Efficient heat dissipation solution for TOPSFLO mini water pump TL-C01
1. Low heat generation and low temperature rise
Choosing a water pump with low heat generation is very beneficial for heat dissipation. As an electronic product, the water pump will generate heat when it works for a long time. If the temperature of the water pump itself is too high, it will cause problems such as overheating and burning, loud noise, etc. In severe cases, it will directly cause damage to the water pump.
The main heat source of the water pump comes from the winding. TOPSFLO Pump Industry has introduced motor engineers from Johnson Electric, a world-leading motor company, and continuously optimized the motor structure design to reduce the heat released when the water pump is working. The electronic components used in TOPSFLO pumps are all temperature-resistant components of international first-line brands, which can not only quickly obtain the support of the original FAE of the electronic control components, but also ensure the quality and improve the heat resistance of the water pump.

The higher the ambient temperature, the more difficult it is to take away the heat. TOPSFLO’s professional team will match water pumps with different functions according to the actual use scenarios of customers, and recommend customers to use water cooling systems of different powers, matching micro water pumps with different functions to achieve the best cooling effect.

3. Material safety, authoritative certification
The trend of medical beauty equipment is to be controlled in accordance with the standards of the medical industry. As the core component of the water cooling system, the safety of the material of the water pump must be absolutely reliable. The earliest medical beauty equipment customer that TOPSFLO contacted once complained: “The mini water pump used before will precipitate a large amount of black particles when working, and the water will turn black in severe cases.” This is a typical internal graphite sleeve that is not wear-resistant.
To ensure the quality of each pump, Dopule is very strict in material selection. TL-C01-B uses PPE imported from Asahi Kasei of Japan as the pump shell material, and promises not to add a single grain of recycled material; the shaft and sleeve are made of highly wear-resistant imported materials; the sealing ring is made of natural rubber imported from Malaysia; the injection-molded magnet and high-precision integrated rotor are all imported from Japan. The product has passed authoritative certifications such as FDA, WRAS, RoHS, NSF, CE, CQC, and REACH.

4. The water pump has a large flow rate and strong performance
The biggest problem with laser beauty equipment is the high heat generation, and in order to pursue faster beauty effects, it is often necessary to use a higher-power laser tube, so the water pump must have a large flow rate to quickly and efficiently take away the heat, making the equipment safer and more reliable.
The final flow of the water pump is closely related to the overall structure, motor, and electronic design and matching scheme. Professional R&D capabilities and the support of professional equipment are indispensable. TOPSFLO Pump Industry has a professional R&D team composed of electronic engineers, motor engineers, and structural engineers with 20 years of rich industry experience. The research on water pump performance is far ahead of the industry. TL-C01-B uses high-efficiency motors and rotors. The water pump efficiency is about 30% higher than similar models in the industry.

What Changes does “Liquid Cooling” Technology Bring to Charging Stations and How to Choose a Reliable Liquid Cooling Water Pump?

Recently, Have you noticed that Huawei’s “liquid-cooled 600kW supercharger station” caused tremendous repercussions on the internet? It is said that this charging station can achieve a “one kilometer per second” charging speed, providing car owners with a charging experience of “having a cup of coffee and setting off fully charged”. This resolves many of the core pain points such as range anxiety and charging anxiety for electric vehicle owners, bringing a completely new charging experience.

Huawei Technologies plans to install 100,000 EV DC fast charging stations in more than 340 cities and major highways across the country in China by 2024, leading the way in achieving “high-quality charging wherever you’re”

 

What is the Liquid Cooling Fast Charging Station?

Different from traditional air-cooled charger, liquid cooling technology utilizes liquids to dissipate heat and maintain equipment temperature. Liquid-cooled ultra fast charging stations use this technology to charge electric vehicles in a shorter period, effectively improving charging efficiency and speed.

First, let’s understand the basic principles of liquid cooling fast charging technology. According to the formula “power = voltage x current” (P = UI), we can see that when either the voltage (U) or the current (I) increases, the power (P) will increase, accelerating the charging speed and reducing the time required to fully charge.

Therefore, achieving high power fast charging mainly involves two methods. Firstly, increasing the vehicle’s charging voltage—the charging voltage for electric vehicles has transitioned from the previous 400V to 800V and 1000V. Secondly, increasing the charging current. The majority of third-party universal fast chargers in China have achieved the 250A current limit recommended by the 2015 national standard. However, vehicle manufacturers’ self-built super-fast chargers can successfully surpass the 250A current limit, achieving a higher 600A current output.

Why Do Electric Vehicle Charging Stations Heat Up So Much?

When the current passes through the resistor, all the electrical energy consumed on the resistor is converted into heat energy. According to Joule’s law (Q=I²RT), the heat generated by the current through the conductor is proportional to the second square of the current, proportional to the resistance and power-on time, that is to say, the greater the current, the more heat generated by the charging pile.

Under the premise of the same resistance and equal time, when charging at 250A, a single charging cable or two charging cables can generate 62,500 joules of heat. And when charging at 600A will generate 360,000 joules of heat. Thus, how charging stations can withstand such high levels of heat has become a technical challenge that charging station manufacturers need to overcome.

How to Achieve the “Black Technology” of Liquid Cooling EV Fast Charging？

In the liquid cooling EV fast charging technology, the role of the liquid-cooled water pump is crucial.This is because the all-liquid-cooled charging station uses a liquid-cooled charging module, with no air ducts on the front and back of the liquid-cooled module. The module relies on the internal circulation of the coolant in the liquid cooling plate to exchange heat with the outside. The heat dissipation liquid is circulated between the charging host and other components to stabilize the temperature and ensure that the charging process is efficient and stable.

Meanwhile, the fully liquid-cooled charging pile has a special liquid circulation channel between cable and charging gun. Liquid coolant for heat dissipation is added to the channel, and the coolant is circulated through a liquid-cooled water pump, thereby dissipating the heat generated during the charging process. The liquid cooling system extends from charging station to charging cable and connector, enabling low-temperature operation of the entire charging system. This enhances the heat dissipation performance, increases the device power density and output power, and is significantly improved compared to traditional air-cooled heat dissipation technology.

|  Market pain points

There are the following difficulties in implementing a liquid cooling solution in 1U/2U server:

1.The problem of limited design space: The original air-cooling design solution is relatively mature. If you want to add a liquid cooling solution while maintaining the original design solution, the layout space for the liquid cooling solution will be very limited. 1U server Height = 4.445 cm, 2U server height = 4.445*2 = 8.89 cm.

2.Sealing and anti-leakage issues: Liquid cooling systems involve the use of a large amount of liquid media, and the core component in the server is the chip (CPU and GPU, etc.). Once the chip comes into contact with liquid, there is a risk of burning, resulting in The entire server is damaged, so it’s crucial to ensure the fluid circulation system is air-tightness and leak-proof.

3.Heat dissipation efficiency and performance issues: More than 55% of chip failures are caused by heat transfer failure or temperature rise. If the chip is above 70 degrees, its reliability will be reduced by 50% for every 10 degrees of temperature increase. Once the quality of the components in the cooling assembly is not good or the circulation design is not effective, there is a possibility of unstable product performance, which will lead to local overheating or insufficient cooling, thus affecting the normal operation of the server.

Water Pump Intelligent Customized FG Signal – Meet Diverse Needs and Enhance Pumping Experience

As an advanced fluid transfer device, brushless DC centrifugal pumps are playing an increasingly important role in various industries. This kind of dc water pump not only has the advantages of high efficiency, low energy consumption and smooth operation, but also has the advantages of easy installation and use, long life and is deeply loved by users, becoming the preferred device in many fields. The FG signal of the brushless DC centrifugal pump is very important for monitoring, controlling and optimizing the operation of the pump, which can improve the stability, safety and efficiency of the system.

What is the FG Signal of a Brushless DC Centrifugal Pump?

The FG signal of a brushless DC centrifugal pump usually refers to the “Frequency Generator” signal line, which usually work through a square wave signal. The frequency of this square wave signal is proportional to the speed of dc water pump. When the motor speed increases, the frequency of the square wave signal will increase accordingly, and when the motor speed decreases, the frequency of the square wave signal will also decrease. Through the frequency change of this square wave signal, the control system can achieve precise control of the motor speed and control it as needed to ensure the stable operation of the water pump.

If the motor speed is lower than the set value, the control system can increase the output power of the motor by increasing the duty cycle of the speed regulation signal, thereby increasing the motor speed. On the contrary, if the motor speed is higher than the set value, the control system can reduce the output power of the motor by reducing the duty cycle of the speed regulation signal, thereby reducing the motor speed.

How is the square wave generated? The FG signal is actually the communication signal of the brushless DC motor. When a communication event occurs, the FG output will toggle. The rotor used in the TOPSFLO water pump has 4 poles, which means that 4 communication events will occur during one rotation of the rotator, and the FG will flip twice to produce a square wave.

Wiring Method of the FG Signal Line

The wiring sequence of the customized 5V/PWM/FG signal line of TOPSFLO DC brushless water pump is generally: red line positive, black line negative, blue line 5V or PWM speed regulation, yellow line FG signal. When the red, black and yellow wires are connected, the water pump works normally; when the yellow wire is not connected, the water pump works, but there is no signal display; when the input current is >50mA, there is a risk of damage to the FG signal circuit of the pump. When measuring speed, a pull-up resistor must be connected. The pull-up resistor is recommended to be between 1K and 10K. It is adjusted according to the pull-up voltage. The greater the voltage, the greater the resistor selected.

FG Wiring Precautions

What kind of applications need to customize the FG signal lines?

The reasons for customizing FG signal for brushless DC centrifugal pumps involve many aspects such as control system requirements, accuracy, integration, and performance optimization. By customizing FG signal lines, customers’ specific needs can be met to ensure that the water pump can achieve the best performance and functionality in its applications. The following are common applications that require customized FG signal lines:

1. Equipment control system requirements: The customer’s control system requires specific types or specifications of signal inputs to ensure optimal performance. For control systems that require specific frequency ranges or signal types, customizing FG signal lines to meet these requirements is necessary.
2. Precision and accuracy requirements: Customer applications require higher measurement precision and accuracy, such as the medical industry, drinking industry, cooling industry, precision instruments, etc. By customizing the FG signal line, the speed of the water pump can be precisely controlled. For example, the speed regulation function needs to be implemented or the pump needs to run at a specific speed under specific conditions. At this time, the FG signal line can provide the operating status and speed information of the water pump to facilitate customers to accurately control and adjust the water pump.
3. Real-time monitoring requirements: The operating status of the water pump needs to be monitored in real time. For example, it is necessary to know the flow rate of the water pump or whether it has stopped due to failure. At this time, customized FG signal lines can collect and monitor these data, helping customers promptly detect abnormal pump operation and take corresponding measures.
4. Integration and compatibility requirements: Customized circuits or wiring schemes are required for customer system integration to meet the overall system design and requirements. In this case, customized FG signal lines can better meet the needs of system integration, providing a more flexible and reliable system solution.

How to choose a water pump meeting automobile power supply way?

As we all know, there are differences between the fluctuated automobile power supply voltage and the stable voltage of household, so the ability of water pump to resist voltage fluctuation is particularly important in automobile applications.
So how to choose a water pump meeting automobile power supply way? This article will discuss with you.

First, we need to understand the root cause of automotive voltage fluctuations.
Typically, the standard voltage is 12V for small and medium-sized cars, and 24V for large and heavy-duty vehicles. The basic power supply system voltage of most passenger vehicles (such as cars, SUVs, etc.) is 12V. The working voltage of the sensor inside the engine is 5V, and the on-board computer board also provides a voltage of 3.3V. Various peripheral devices usually use 12V power supply, such as electrical appliances on the vehicle, control modules, etc. Peripheral appliances such as lights, horns, engine cooling fans, wipers, instrument panel assemblies, control panels, audio, window motors, central locking, starters, and air-conditioning motors all use 12V voltage.

However, the actual 12V voltage is not fixed. If you measure the voltage across the battery with a multi-meter, you’ll find a different value. After the vehicle is turned off, the battery voltage is usually between 12-13V, or even lower; and after the vehicle is started, the battery voltage will fluctuate in the range of 12-14V. Therefore, it is normal to measure the battery voltage in the range of 12-14V. The voltage supply of vehicle equipment is also limited to 14V, and the maximum withstand voltage is between 14-14.8V.

So, where does 14V come from?
It comes from the car’s alternator. Although the starter no longer works after the vehicle is started, many electrical appliances start to run and consume electricity. If the generator can’t replenish the power in time, the battery will run out of power very quickly. Therefore, when the engine is started, the generator also starts working immediately. In order to charge the battery, the output voltage of the alternator must be higher than the battery voltage. By creating a voltage difference, current flows from the alternator to the battery. However, this voltage difference should not be too large, otherwise the battery may be overcharged and damaged. Therefore, the maximum output voltage of the generator is limited to 14.5V.

Next, let’s take a deeper look at how an automotive power system works.
The battery, generator and on-board electrical appliances are all connected in parallel. When the engine is running normally, the alternator not only supplies power to the on-board electrical appliances, but also charges the battery. When starting, the battery supplies power to the starter. The discharge warning light is used to indicate the charging and discharging status of the battery. The role of the regulator is to ensure that the generator can maintain a stable output voltage when the speed changes. The task of the automotive power system is to provide low-voltage DC power supply (usually 12V for gasoline vehicles and 24V for diesel vehicles) for all on-board electrical appliances to ensure the normal operation of various parts of the vehicle.

The voltage of the car power supply can be divided into the following two situations:
12V system: The no-load voltage of the battery is about 13 volts, and the load voltage should not be lower than 11 volts, otherwise it may cause difficulty in starting.
24V system: The no-load voltage of the battery is about 26 volts, and the load voltage should not be lower than 22 volts to avoid difficulty in starting.
When the generator starts generating power, the voltage should be between 13.5-14.5 volts for a 12V system, and between 27-29 volts for a 24V system.

Under the premise of knowing the rated voltage, what factors will affect the selection of a suitable automobile water pump?
1. Rated power of the pump: An increase in the power of the pump results in an increase in the required voltage. If a low voltage is input into a high-power automobile water pump, not only will the efficiency be low, but the motor may even be damaged.
2. Stability of power supply: Water pumps usually need to run for a long time, unstable power supply will have a negative impact on it, and even damage the motor. Therefore, when choosing the rated voltage of the automobile water pump, the stability of the power supply is very important. If the power supply is unstable, it is recommended to consider installing a voltage stabilizer.

After receiving the automobile water pump, how to confirm its rated voltage?
1. Check the pump itself: Most pumps have voltage information marked on the body. By checking these markings, you can confirm the rated voltage of the pump.
2. Check the product manual: The product manual usually clearly states the rated voltage of the pump, and the voltage requirements of the pump can be confirmed by reading the manual.
3. Consult the manufacturer: If the above methods cannot determine the rated voltage of the pump, you can directly contact the pump manufacturer for answers.
After determining the rated voltage of the pump, be sure to choose a power supply that matches the rated voltage of the pump to avoid possible failures and equipment damage.

Over the years, TOPSFLO has been committed to the R&D, design and production of brushless DC water pumps. The TA50 and TA60 automotive water pumps adopt a special electronic design scheme, which can run stably under the complex situation of car charging and discharging. This makes the automotive electronic water pump not affected by the high peak voltage of the automotive power supply, and can run stably and durably under various voltage conditions.
Operating voltage range for 12V automotive pump: 9V-18V.
Operating voltage range for 24V automotive pump: 18V-32V.
This wide operating range far exceeds the fluctuation range of the power supply voltage, providing users with a reliable guarantee.

Popular Science Class l Why is the Brushless DC Water Pump Strictly Prohibited From Dry-running?

The dry-running of the brushless DC water pump means there is no water in the pump chamber, or there is an excessive amount of air in the pump chamber when the water pump is running. That is, the water pump runs without water or with poor water flow. When the water pump is working, the water plays an important role in lubrication and cooling, so dry-running is absolutely not allowed. Let’s explore the reasons why the brushless DC water pump is strictly prohibited from dry-running, and the factors that may cause this phenomenon. At the same time, we will also discuss what measures can be taken to prevent the water pump from dry-running.

Do not run without water
Why is the brushless DC water pump strictly prohibited from dry-running?
The brushless DC water pump may cause the following problems when dry-running:

Damage to the water pump motor: the rotor of the water pump motor rotates at high speed when dry-running, but there is no water cooling, which will cause the motor to overheat, thereby damaging the motor insulation and bearings, and shortening the lifespan of the motor.

Cause the pump to be stuck: the pump body will generate heat when dry-running. Without the liquid cooling, those narrow gaps are easy to be bitten through due to the long-term thermal expansion and contraction, resulting in the pump being stuck and unable to work normally.

Increase the power consumption: the motor will work without load when dry-running, and the power conversion efficiency will be low, which will cause energy waste and increase power consumption.

Affect the sealing performance of the water pump: dry-running may cause excessive frictional heat at the seal of the water pump, which will affect the sealing performance and cause leakage from the pump body.

Cause harm to other equipment: dry-running may lead to overpressure of the pipeline, and even cause other equipment failures, which will have a chain reaction on the system.
Therefore, in order to protect the normal operation of the pump and prolong its service lifetime, it is strictly forbidden to have the brushless DC water pump from dry-running.

Possible Reasons for Dry-running
1. No water supply: Brushless DC water pumps are prone to dry-running when there is no water or insufficient water. For example, the inlet of the water pump is not connected to the water supply or the water supply is suddenly interrupted.
2. Blockage or leakage: If the inlet of the water pump is blocked or leakage occurred, the pump cannot absorb water normally, which may cause dry-running.
3. Failure of the control system: If the control system of the water pump fails, the operation status of the water pump cannot be monitored correctly, which may cause the water pump to continue to run without water and dry-running.
4. Power problem: Unstable power supply or power failure may cause the water pump to fail to operate normally, resulting in dry-running.
5. Improper installation: Improper installation of the water pump or improper connection of the pipes causes the water pump to fail to pump water normally.

How to Prevent the Water Pump from Dry-running?
1. The pump inlet must be connected to a pipeline with water source, and being lower than the water source to ensure that water can enter the pump smoothly.
2. Use a suitable pump controller, such as a pressure switch, flow switch or smart controller, to monitor the running status of the pump and avoid dry-running.
3. Choose a water pump with dry-running protection, so that when the water pump runs without water, it will automatically stop working to avoid damage.
4. Regularly maintain the water pump, check the running state of the motor, the sealing and the pipeline connection, to ensure that the water pump is running in the best condition.

Dry-running Protection of the Water Pump

When the brushless DC water pump lacks water during running, it may face the risk of burning out. However, the water pump equipped with dry-running protection can realize short-term dry-running when the internal environment is wet, and effectively avoiding the occurrence of burn-in.

All the brushless DC water pumps produced by TOPSFLO are equipped with dry-running protection (either standard or customized). The role of this function should not be underestimated. The electronic control system of the water pump can realize the intelligent monitoring of the current and speed, and accurately triggers the corresponding protection measures according to the set threshold. When the current and speed are lower than the predetermined threshold, the system immediately starts the dry-running protection, so as to ensure that the water pump is not damaged or malfunctioned.

The dry-running protection can monitor the running status of the water pump in real time, accurately identify possible abnormal situations, and respond quickly. Once the system finds that the pump current or speed deviates from the predetermined range, it will immediately take corresponding measures to reduce the pump speed, stop the pump operation or issue an alarm to avoid damage or accidents caused by dry-running.

Do you know the main parameters of the brushless DC water pumps

In the industrial and civil sectors, brushless centrifugal pump are widely used as efficient and reliable fluid transportation equipment in various fields such as industry, agriculture, and healthcare. This article provides a detailed introduction to the main performance parameters of brushless DC centrifugal pumps, as well as an interpretation of the labels of TOPSFLO water pumps, to help you better understand and choose brushless centrifugal pumps.

1. Flow rate parameter
Flowrate is one of the important performance parameters of a brushless centrifugal pump. It represents the amount of liquid that the pump can deliver per unit of time. Flowrate can be measured in terms of volume flowrate or mass flowrate.
The volumetric flow rate (Q) refers to the volume of liquid conveyed by the pump in a unit of time, commonly used measure units are litres/minute (L/min), cubic metres/hour (m³/h) and so on. The volumetric flow rate determines the pumping capacity of the pump. For different application requirements, it is necessary to select an appropriate volumetric flow rate based on the liquid delivery needs.
TOPSFLO pumps are usually labelled with the volumetric flow rate and also the maximum flow capacity (Max water flow / Max air flow / Max flow / Max flow without pressure ), which indicates the maximum flow rate that the pump can achieve without actual load pressure. When the outlet of a brushless centrifugal pump is not connected to any pipework, the flow rate will be at its maximum, but no pressure will be generated.

2. Water head parameters
Water head is a key indicator of the performance of brushless centrifugal pumps. It represents the increase in effective energy per unit mass of liquid from the pump inlet to the pump outlet. The water head determines the pumping capacity of the pump and the height or pressure at which the liquid can be delivered.
The water head is measured in meters (m) and represents the height of the liquid column that can be conveyed. However, the water head does not only represent the height of the liquid, it also includes the energy required to overcome fluid resistance and lift both static pressure and kinetic energy. Therefore, the water head is a key parameter for determining the pump’s ability to transport liquid.
TOPSFLO pumps are often labelled with a maximum pressure capacity, i.e. open pressure (Max water head/Max pressure/Open pressure/Open pressure/open pressure without flow), which indicates the maximum pressure that the pump can achieve without actual flow. When a brushless centrifugal pump pumps water to a maximum limit point, no further flow will come out.

3. Speed parameter
Speed (n) represents the number of rotations the pump shaft makes per minute, measured in revolutions per minute (r/min). Under constant speed, the flow rate, water head, and power remain unchanged. When the speed changes, the flow rate, water head, and shaft power of the brushless centrifugal pump will also correspondingly change. The selection of speed has an impact on the flow rate, head, and pump efficiency. Different application scenarios require the appropriate speed to be chosen based on specific requirements.

4. Power Parameters
Power indicates the work done by the pump in a unit of time.
Effective power (Ne) represents the work done by the pump on the conveyed liquid in a unit of time, commonly used unit is watt (W) or kilowatt (kW). It can be calculated through the flow rate, water head and liquid density, this is an important indicator of pump efficiency.
The shaft power (N) represents the pump input power, also indicates the power transferred from the prime mover to the pump shaft. The shaft power is usually less than the effective power because there are various losses within the pump that do not allow the input power to be fully converted into the effective power of the liquid. Shaft power is also expressed in watts (W) or kilowatts (kW).
The mating power (ND) is the power of the prime mover that is mated to the brushless centrifugal pump. Its relation to the shaft power can be calculated by a factor. Mating power is usually used to determine the required prime mover power to ensure proper pump operation.
Input electric power (P) is the input power, also indicates the total electric power that the pump obtains from the power supply. The input power includes the electrical energy required to run the pump as well as the motor’s own losses. It is usually expressed in watts (W) or kilowatts (kW).
It should be noted that the power indicated on the nameplate of brushless centrifugal pumps is not the effective power, but rather shaft power, rated power, or input power. For example, the power indicated on the TOPSFLO water pump label is the input power.

5. Other Parameters
In addition to flow rate, water head, speed, and power, there are other parameters that need to be considered, such as operating temperature, material corrosion resistance, noise level, etc. These parameters should be selected based on specific application scenarios and requirements.
By understanding the performance parameters of the pump, it is possible to accurately match the characteristics of the pump with the application needs. For example, understanding the flow rate can determine the pump’s conveying capacity, allowing the selection of an appropriate flow rate to meet the actual requirements. Understanding the head can determine the pump’s delivery height or pressure requirements, ensuring that the pump can provide sufficient lift. Understanding the shaft power and effective power can evaluate the pump’s energy conversion efficiency, and selecting a high-efficiency pump can provide greater effectiveness. Having a clear understanding of the performance parameters of the pump also helps in selecting suitable supporting equipment such as motors and controllers, while avoiding the risks of overload and damage.
In conclusion, the performance parameters of brushless centrifugal pumps are of significant importance for correctly selecting and applying pumps. By fully understanding the performance parameters, it is possible to better select a pump that suits the requirements and ensure that it can achieve the best results in practical applications.

Understanding the Working Principle and Key Selection Criteria of Laser Cooling Circulation Pumps

However, laser generators generate significant heat during extended operation. If the laser tube’s temperature rises too high, it can lead to irreversible damage, reduced output power, and negatively impact the quality of the processed materials. Prolonged overheating can also shorten the laser tube’s lifespan. Given the high cost of replacing laser tubes, an effective water cooling system is essential to maintain optimal temperature control and ensure long-term operation.

Working Principle: In the heat exchanger, the circulating water absorbs heat from the laser cavity. The heated water then returns to the water tank, where it passes through a filter and pump, continuing the cooling cycle by carrying heat away from the laser. The water then re-enters the heat exchanger to repeat the process, effectively maintaining a stable temperature.

Selection Criteria: The performance of the centrifugal water pump plays a pivotal role in the effectiveness of the laser cooling system. Here are key factors to consider when selecting a pump:

1. Intelligent Control: For precise temperature regulation in industrial settings, a DC brushless centrifugal pump with intelligent control is recommended. This pump’s PCBA control board ensures fast, accurate responses to temperature fluctuations, preventing overheating of sensitive components.
2. Consistent Water Flow: Pumps with high batch consistency and low failure rates, like TOPSFLO laser cooling pump, are ideal. These pumps provide reliable, stable flow, ensuring constant laser wavelength and prolonging the laser’s life.
3. Long Lifespan: Opt for pumps that offer over 20,000 hours of operational life, ensuring safe, long-term performance without aging-related issues that could impact the cooling system or laser efficiency.
4. Superior Sealing and Leak Prevention: Choose pumps like the TL-B10, which feature advanced static sealing and high-strength, stable structures made with imported Japanese PPE materials to guarantee reliability and airtightness.

01 What is liquid-cooled commercial and industrial energy storage

While traditional energy storage systems often suffer from energy loss and heat dissipation, the core of liquid-cooled commercial and industrial energy storage is the coolant circulation system, which keeps the temperature of the equipment within a controlled range by circulating coolant through the energy storage equipment, absorbing heat and carrying it away. This cooling technology can significantly improve the efficiency of energy storage systems, reduce energy losses, and increase system reliability and lifetime.
Liquid-cooled energy storage is in a rapid development stage, the technology continues to mature and improve, and is widely used in a number of applications, and can be used in energy storage power plants, grid peaking and leveling, backup power and other scenarios. Broad market prospects. With the rapid growth of renewable energy and the change of power system, liquid-cooled commercial and industrial energy storage is expected to become one of the important means to achieve clean energy transition and improve the flexibility of power system.

02 The role of water pump in liquid cooling system

Water pump is an important component in liquid-cooled commercial and industrial energy storage systems, undertaking two key functions: circulation and liquid replenishment.
In the circulation function, the water pump directs coolant from the energy storage unit to the cooling equipment through high efficiency, adjustable flow and pressure output to reduce the system temperature and maintain the normal operating temperature of the energy storage unit. The high efficiency and adjustability of the water pump enable it to adapt to different load requirements and improve the efficiency of energy utilization.
As for the liquid replenishment function, the water pump plays a key role of automatic liquid replenishment. During the operation of the system, the coolant may decrease due to evaporation or leakage, when the water pump will automatically start according to the change of system pressure monitored by the system and replenish the right amount of coolant to maintain the cooling effect and safety of the system.

03 Specific requirements for different functional water pumps

The design and selection of pumps for liquid-cooled C&I energy storage systems requires consideration of the system’s flow requirements, pressure requirements and piping resistance. Depending on the specific liquid-cooled system design and requirements, the type, power and operating mode of the pump may vary.

–A. Circulation function water pump:
Flow rate and pressure: The pump needs to provide sufficient flow rate and pressure to meet the circulating demand in the liquid cooling system. The specific flow and pressure requirements depend on the size of the system, the design parameters and the heat load of the liquid cooling equipment. Typically, larger liquid cooling systems may require higher flow rates and pressures.
High performance: The pump should have high performance characteristics to ensure that it provides the required flow and pressure while minimizing energy consumption. High performance pumps help improve the energy efficiency performance of liquid cooling systems, reducing energy consumption and operating costs.
Corrosion resistance: Considering the corrosive liquids or chemicals that may be present in the liquid cooling system, the circulating water pump needs to have a certain level of corrosion resistance to prevent corrosion, liquid leakage and equipment damage.

–B. Liquid replenishment function water pump:
Liquid replenishment capability: The liquid replenishment pump needs to have sufficient liquid replenishment capability to maintain the required coolant level in the liquid cooling system. It should be able to inject the right amount of coolant automatically or manually when needed to replenish the coolant lost due to evaporation, leakage or other reasons.
Precise control: The charge pump should have precise control to ensure that the charge level meets system requirements and to avoid over- or under-filling. Accurate charge control helps maintain system stability and cooling effectiveness.
Automation integration: The charge pump usually needs to be integrated with the control system of the liquid cooling system. It should have the ability to communicate with the control system, be able to automatically perform the replenishment operation according to the system requirements, and automate the system operation.

These requirements are based on general liquid-cooled commercial and industrial energy storage systems and may vary depending on the specific application and design. Therefore, ensuring the selection of the right type, size and performance of pump for a practical application usually requires consideration of the specific requirements, technical parameters and performance specifications of the system, and may require further discussion and consultation with a professional engineer in the relevant field.

How to Choose Automotive Coolant ?

Automobile antifreeze, also known as “antifreeze”, the full name is “automobile antifreeze coolant”. Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as antifreeze in winter, anti-boiling in summer, anti-scale and anti-corrosion throughout the year.

When driving in the northern China, antifreeze must be used when the vehicle survives the winter, and antifreeze is divided into different levels, suitable for different temperature environments. Although the temperature in winter in the south is not as cold as in the north, there is always a period of time when the temperature is quite low, so it is best to use antifreeze to be on the safe side. Actually antifreeze is engine coolant, which is an indispensable heat dissipation medium for the normal operation of automobile engines.

1. Types of antifreeze
There are many types of automobile antifreeze, such as calcium chloride (CaCl2) in inorganic substances, methanol (CH3OH) in organic substances, ethanol (C2H5OH, common name alcohol), ethylene glycol (C2H4 (OH) 2, common name sweet alcohol), Glycerol (C3H5(OH)3, commonly known as glycerin), lubricating oil, and common sugar and honey in our daily life can be used as the mother liquid of coolant Ionized water, such as distilled water, unpolluted rainwater, snow water, etc., can become an antifreeze in the general sense after the total hardness component concentration of the water quality is between 0-30ppm).

Since methanol and ethanol are relatively volatile, they are not suitable for vehicles in northern China.

Currently, ethylene glycol is used in more than 95% of water-based antifreeze. Ethylene glycol is a colorless slightly viscous liquid with a boiling point of 197.4℃ and a freezing point of -11.5℃. It can be mixed with water in any proportion. Compared with tap water, the most notable feature of ethylene glycol is that it is antifreeze, while water cannot be antifreeze. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability. Therefore, ethylene glycol-type antifreeze is an ideal coolant, and conventional antifreeze is generally produced with ethylene glycol as the main raw material.

2.Freezing coefficient of antifreeze
The conventional cooling levels of antifreeze are -25℃, -35℃ and -45℃，which are more common for us.
Automobile manufacturers usually specify the mixing ratio of antifreeze for different low-temperature antifreeze levels in the user manual, and also specify the type of antifreeze, which cannot be mixed.
Generally, when the ratio of antifreeze to water is 40:60, the boiling point of the coolant is 106℃, and the freezing point is -26℃. When it is 50:50, the boiling point of the coolant is 108℃, and the freezing point is -38℃. Normally it is required to prepare coolant at a temperature lower than the local minimum temperature of about 5℃.

3.How to choose antifreeze
There are two main points to measure the pros and cons of antifreeze:
The first is the antifreeze effect. The freezing point of water is 0℃. Generally, ordinary antifreeze can reach -40℃, while high-quality antifreeze should reach about -60℃. This is an important indicator for calibrating the quality of antifreeze.
The other is the boiling point of antifreeze. The boiling point of water is 100℃, and the antifreeze should be at least 108℃. That is to say, the lower the freezing point, the higher the boiling point, and the greater the temperature difference, the better the quality of the antifreeze.

In addition, it is necessary to pay attention to the anti-corrosion and anti-rust performance, and choose antifreeze with anti-rust, anti-corrosion and descaling capabilities as much as possible. Because some cheap antifreeze will use cheap calcium chloride, industrial salt and other inorganic salts, methanol, industrial alcohol and other alcohols to replace ethylene glycol, these alcohols volatilize quickly, and inorganic salts are easy to precipitate , and is highly corrosive to metals, causing great damage to automobile engines.

4.  Matching of Coolant and water pump
In the cooling system of an automobile engine, the matching of the antifreeze and the water pump is related to the normal operation and reliability of the automobile engine.
For example, military-grade automobiles require that pump can start normally at extreme temperature of -41℃, so the freezing point of the antifreeze must be lower than -41℃, and the temperature resistance of the water pump used must match the freezing point of the antifreeze to ensure the smooth start of the car.

TOPSFLO has 18 years of experience in research and development of micro pump products, and has created mature low temperature resistance solutions for the automotive industry. The TA50 and TA60 series electric coolant pump of high-quality automotive electronic pumps produced by TOPSFLO will not cause the engine to fail even at an extremely low temperature of -50°C, which fully meets the heating needs and has been widely recognized by customers, such as Tesla, BAIC, Shaanxi Auto and so on.

Electric water heater brushless DC booster pump solution recommendation

Background Introduction

Electric water heater is a water heater that uses electricity as an energy source for heating. It is one of the three major water heaters alongside with gas water heater and solar water heater. It can be divided into three types according to the size of heating power: storage type, instantaneous heating type and quick heating type.

Among them, the instantaneous water heater does not require the use of any stored hot water, instant hot, can meet the demand for hot water 24 hours a day, no waste of energy, loved by the majority of customers. However, during peak electricity consumption, the unstable voltage input leads to changes in water flow, and changes in water flow lead to sudden cold and hot water temperature; there is also too much noise when the water heater is in use and other conditions directly affect the user’s shower feeling. So electric water heater manufacturers commonly through the built-in booster pump to solve this problem.

Working Principle

The electric water heater is a household electrical equipment in which cold water enters the water heater and then the water is instantly heated by the brushless DC booster pump to the heating system, and then the water is circulated to each water-using unit.
The simple principle schematic diagram is as follows, mainly composed of power supply, brushless DC booster pump, solenoid valve and flow valve assembly, and heater tank assembly.


The principle of operation of electric water heaters is based on the following steps:

Cold water enters the electric water heater: Cold water enters the container of the water heater through the inlet pipe.
Water pump conveys water: The electric water heater is equipped with a brushless DC booster pump, which is responsible for conveying cold water from the tank to the heating system. The water pump generates centrifugal force by rotating and pushing the water towards the heating element.
The heating system heats the water: As the water enters the heating system, it comes into contact with the heating element (usually an electric heater or heat generator), which heats the water by passing an electric current through it.
Hot water supply: Once the water is heated to a set temperature, hot water flows out of the heating system and is transferred to each water-using unit (e.g. sink, shower, etc.) via the outlet pipe.

Technical requirements for  electric water heater booster pumps

In order to achieve a good match between the electric water heater and the brushless DC booster water pump, the manufacturer should consider the following requirements when designing and selecting the micro water pump, and conduct sufficient tests and verifications to ensure its performance and reliability in the electric water heater application.

Although the electric water heater achieves fast heating, the traditional AC pump, which is vulnerable to noise and voltage floating interference. So for electric water heaters, TOPSFLO micro pumps have the following two options to recommend:

For electric water heaters with power above 8KW, TOPSFLO recommends DC booster pump TL-C01 series:
TL-C01-C12-2411  24L 11M
Noise: ≤42dB(A) IP Grade: IP68，suitable for wet environments
Ambient temperature：-40℃~40℃ Liquid temperature:-40°℃~75°℃
Built-in intelligent chip, adjustable flow and signal feedback Compared with traditional AC motors, the efficiency is increased by 30%


For electric water heaters with a power of 3-8KW, TOPSFLO recommends the DC booster pump TL-B10 series
TL-B10-D24-1208  12L  8M
Noise:<40dB(A) IPGrade:IP68，suitable for wet environments
Ambient temperature：-40℃~40℃ Liquid temperature:-40°℃~75°℃
Built-in intelligent chip, adjustable flow and signal feedback Compared with traditional AC motors, the efficiency is increased by 30%

Customers can choose the appropriate model according to the actual application requirements, or contact our sales staff for more detailed information. We look forward to providing you with quality products and services.

Is it possible to customize the product?

We have our own independent structural engineers, electronic engineers, electrical engineers, and process engineers. If the customer’s project must require some non-standard samples or additional customization, after the customer tests our standard products to confirm that the basic parameter performance is ok, we can according to Customize structure/electronics/motor according to different customization requirements of customers.

Can this brushless dc pump run dry?

No, definitely not! Magnetic drive pumps will incur damage even after short periods of dry running. Our advice is to ensure that the pump has a flooded suction or always make sure that the pump casing and inlet pipe are filled with fluid; one way of ensuring this is to fit a check valve on the inlet line to stop water escaping when the pump is inactive. Another way of protecting the pump is to fit a dry running device, this will turn the pump off if it detects that no fluid is entering the pump. If you think that dry running is inevitable, then please speak to us and we will try to select a more suitable pump for your application.

What is a magnetic drive and what are the benefits?

A magnetic drive is a means of sealing a pump without the requirement of a mechanical seal. Magnets are used to transfer torque from the motor shaft to the shaft within the pump head.
There are many benefits of sealing the pump in this fashion, including;
• A mechanical seal does not need to be regularly replaced due to wear and tear, this greatly reduces maintenance costs.
• A seal flush is not required for seal lubrication.
• The fluid is fully contained within the pump, this means there are zero chances of leakage. This is a great benefit when handling hazardous and corrosive products.

About the Laser Tube Cooling for 3D Laser Printer

As the Ministry of Education attaches great importance to students’ quality education, more and more schools and families begin to pay attention to children’s hands-on ability. 3D printers (also known as 3D laser engraving machines) have become widely used in school and family education.

The speed and lifespan of a 3D printer are closely related to its key component, the laser tube. At present, it is generally considered to use a CO2 laser tube of about 40W for home use, and the speed is relatively fast.

Today, let me show you the product structure and cooling method of CO2 laser tubes. This will help you better choose a high-quality and durable 3D printer.

Structure of CO2 Laser Tube
The CO2 laser tube is composed of CO2, nitrogen, hydrogen and other gases. With a laser wavelength of 10.6 μm, the laser beam generates a power of more than 20 kilowatts, which can achieve continuous work. It is often used in laser marking machines and laser cutting machines. CO2 laser tubes are used in a wide range of applications.

(Cooling structure diagram of CO2 laser tube)

The basic structure of the CO2 laser tube is shown in the figure above. It is mainly composed of hard glass, resonant cavity and electrodes.
The hard glass part is composed of a discharge tube, cooling tube, gas storage tube and gas return tube.
The discharge tube is a key component in CO2 lasers, which basically determines the characteristics of the laser output.
The function of the cooling tube is to cool the working gas, maintain a stable output power, and prevent the discharge tube from bursting due to heat during the discharge pumping process.
The function of the gas storage tube is to increase the gas storage capacity of the gain medium and enhance the mechanical strength and stability of the discharge tube.
The air return pipe can improve the unbalanced distribution of the voltage between the electrodes caused by the electrophoresis phenomenon.

Pain Points of CO2 Laser Tube Cooling
There are two types of laser tubes with the same power: catalytic type and sealed-off type. The catalytic type CO2 glass laser tube (enhanced type) is an upgraded product of the traditional sealed-off laser tube. The service life and power are greatly improved by coating the nano-high-efficiency catalyst film in the discharge tube, and the adjustable inner cavity structure greatly improves the light quality of the laser tube, so that the cutting efficiency and engraving precision in the application are greatly improved.

Whether it’s the catalytic type or the sealed-off type CO2 laser tube, a lot of heat will be generated during working, and the temperature of the discharge tube will be too high. However, its own heat dissipation capability is limited, and the temperature will continue to rise. Thus a cooling system is needed to cool down the internal temperature of the laser tube.

At present, there are two main methods of CO2 laser tube cooling: air cooling and water cooling.

Air cooling is often used for low-power lasers, while water cooling covers the entire power range that CO2 lasers can achieve. The effect of water cooling is generally 3-5 times that of air cooling, which can effectively avoid the problem of equipment burn-in caused by poor cooling effects.

Generally, household 3D printers can directly integrate cooling water pumps into the equipment, while large-scale commercial high-power printers may consider adding a chiller for cooling.

The laser chiller is a right-hand assistant for CO2 laser tube cooling. It has a built-in water cooling system. The cooling liquid is circulated through the operation of the water pump, which takes away the high temperature of the laser tube and returns it to the evaporator. After reducing the water temperature, it returns to the laser tube, which can constantly keep the CO2 laser tube equipment within an appropriate range, guaranteeing for the laser equipment to work for a long time. The laser chiller has a water temperature adjustment function, and the water temperature setting range is from 5 to 35°C, which can meet the individualized temperature setting requirements of different CO2 laser equipment.

Due to the unstable structure of the cooling system of the common CO2 laser tubes currently on the market, excessive fluctuations in the flow rate of the cooling water can break the power generation tube.

Therefore, whether it is a household or commercial 3D printer, a high-quality laser printer cooling water pump is urgently needed on the market.

Laser Tube Cooling Water Pump Recommendation

Since entering the laser tube cooling industry in 2014, TOPSFLO has nearly 10 years’ experience in mass production and verification. Laser printer cooling water pumps TL-B03, TL-B10, TL-C01, etc. are very popular in high-end markets in Europe and America.

It can run continuously for 24 hours and has a life span of up to 30,000 hours. 100% of the key electronic components are imported and traceable. The rotor is injection-molded by a Japanese-funded enterprise with high precision and no leakage. Small size and easy installation, it’s ideal for C02 laser tube cooling.

Why is it Said that Home Energy Storage will Enter the “Liquid Cooling Era”?

This year, a branch of new energy storage – home energy storage, suddenly became popular in the global market. Continued increases in energy price and electricity price have rapidly driven the adoption of home energy storage devices abroad.
“Just like the air conditioners of the 90s”, some market veterans used this as a metaphor for home energy storage. On one hand it means that it is like the air conditioner in the 90s in overseas markets, and on the other hand it means that the appearance of home energy storage is gradually comparable to the volume of a cabinet air conditioner, and integrated home appliances are gradually becoming a trend.

With the rapid development of home energy storage, liquid-cooled energy storage systems are gaining more and more attention.

Overseas Demand for Home Energy Storage has Exploded

Due to the soaring price of energy and electricity in Europe, North America, and other countries or regions such as Africa with high electricity prices but poor stability, the application of home PV + energy storage can improve the level of electricity self-generation and self-consumption, delay and reduce the risks brought about by electricity price increases, and at the same time obtaining stable power support, thus the demand is rapidly rising.

Huajing Industry Research Institute predicts that from 2021 to 2025, the growth rate of new home energy storage overseas will be maintained at more than 60%, and the total capacity of new user-side energy storage overseas will be close to 50GWh by 2025. According to the “Analysis of the Market Size and Industry Investment Prospects of the 2022 Home Energy Storage Market,” the global market size of home energy storage was $7.5 billion in 2020, and the Chinese market size was $1.337 billion, equivalent to RMB 8.651 billion. It is expected that by 2027, the global market size will reach $26.4 billion and the Chinese market size will reach $4.6 billion.

Oriental Securities Research Report also pointed out previously, the Russian-Ukrainian conflict has intensified the panic of the European energy crisis, promoting the European household energy storage market explosion.

Relevant listed companies in the industry are accelerating the layout of the home energy storage market. In the face of rapid expansion of home energy storage capacity, analysts and listed companies are optimistic that the market still has a large growth space.

Liquid Cooling Temperature Control has Become a Market Trend

Liquid cooling system is a temperature control technology for battery temperature management. Air conditioners, electric vehicles, and charging piles that we are more familiar with will use temperature control technology. Temperature control system plays a vital role in the safety, efficiency and lifespan of energy storage.

Air-cooled technology was first commonly used in energy storage systems because of its simple structure, mature technology, low cost and rapid delivery and deployment. As a medium and long-term technical solution, liquid cooling will gradually increase its market penetration. Why is liquid-cooled temperature control becoming a trend in the energy storage market?

1. Safer Working Conditions

The threshold of liquid cooling energy storage technology is relatively high, it is not a simple system heat dissipation. It uses a circulating water pump to drive the cooling liquid convection to directly dissipate heat to the battery cells. The method is controllable, and not affected by external conditions. Besides, the heat dissipation efficiency is high, and the temperature control is more precise, which can greatly reduce the risk of temperature runaway, fire and explosion. As far as the liquid cooling system is concerned, the key point is to ensure that no liquid leaks.

Choosing a pump with better sealing can effectively solve the problem of liquid-cooled energy storage system leakage. TOPSFLO imported advanced production equipment from the United States, France, Japan and other countries for high-precision production, high surface finish, and innovative use of special design inlet & outlet connection, and pipeline connection tight fit without gaps. In addition, imported gas-tight testing equipment (leakage value: 1Pa) is used to conduct tests higher than the industry standard, which can effectively eliminate the risk of pump leakage.

2. Lower Operation and Maintenance Cost

In addition to safety, energy storage system design should also take into account the whole life cycle of operation and maintenance, which generally needs to ensure stable operation for more than ten years. Moreover, energy consumption control is also the focus of liquid-cooled energy storage.

Liquid-cooled system does not make the energy storage itself produce a large self-consumption of electricity, compared with the air-cooled system, can save 30%-50% of energy consumption, effectively reducing operating costs.

TOPSFLO liquid cooling pump has the characteristics of maintenance-free, and can be customized according to customer requirements with a lifespan of 50,000 hours to meet the long-term operation needs of the energy storage system. 38 in-depth inspections for all-round performance that are stricter than industry standards. Each water pump has undergone comprehensive performance inspections before leaving the factory, and product reliability is guaranteed.

3. Smaller Size and More Intelligent Management

In addition to meeting the basic safety and operation requirements, small size and intelligence are undoubtedly the higher pursuit of industry customers for liquid-cooled energy storage systems.

Based on the characteristics of the liquid-cooled energy storage system, TOPSFLO uses the core technology of the liquid cooling system pump industry to design ingeniously.

More energy-saving and more efficient! TOPSFLO assists chillers to achieve rapid cooling

With the continuous development of social economy, machines have become a necessity for industrial production activities. In order to ensure the use effect of machines and product quality, cooling and maintenance equipment such as chillers have become an indispensable and critical part of the production process.

Chiller, commonly known as freezer, refrigerating machine, ice machine, cooler, etc., are cooling water equipment that can provide constant temperature, constant flow, and constant pressure.

The demand for chiller is showing a straight-line upward trend in the domestic and even global markets. It is widely used in many scenarios such as industry, electronics, medical pharmaceuticals, printing, food processing, energy storage temperature control, laboratory and computer room equipment, 5G base stations, etc.

The cooling water temperature of the chiller can be automatically adjusted according to the requirements, almost no water consumption, and long-term use can save a lot of water. It is an ideal device to quickly achieve the ideal cooling effect and save energy.

The chiller transmits the coolant (cooling water or coolant) to the equipment to be cooled through three interrelated systems: refrigerant circulation system, water circulation system and electrical automatic control system. The coolant takes away the heat from the equipment and flows back to the water tank. The reciprocating cycle achieves the role of cooling.

In the overall equipment, the circulating water pump to transport the coolant plays a vital role. How to improve the cooling capacity of the refrigeration system to the maximum at the same time, the cooling circulation pump can achieve the maximum output more efficient and energy-saving, faster to provide cooling equipment, is the urgent demand and development trend of the market.

TOPSFLO has launched the chiller cooling circulation pump TL-C01 as early as when the market needed more efficient and energy-saving water pumps.
TOPSFLO has a team of R&D engineers with more than 20 years of industry experience, and has strong independent R&D and design product strength. In the early stage of product development, the water pump performance review and temperature rise review are strictly followed, international first-line brand electronic components are used, the motor and electronic solutions are reasonably controlled, and the layout design has as much heat dissipation area as possible, which has better temperature resistance. The chiller water pump can achieve the maximum output under the given power, the overall heat generation of the water pump is smaller, and the loss is lower. While the efficiency is high, it will not bring more heat sources and affect the heat dissipation of the overall equipment.

Chiller Cooling Circulation Pump Manufacturer-1

TOPSFLO R&D engineers have compared and tested chiller water pump TL-C01 and the same parameters and power pumps (50W) on the market. TL-C01-C24-2411 can stably output a flow rate of 24L/min, while the comparison pump can only achieve a maximum of 18L/min. Under the same conditions, TOPSFLO cooling water pump efficiency is 30% higher, outputting more effective work, more efficient and energy-saving.

At the same time, the factory is equipped with more than 100 sets of international advanced automation equipment. On the premise of improving productivity and helping customers save production costs, it can effectively guarantee the batch consistency of water pumps, so that customers can choose with confidence.

Taking advantage of technological innovation, TOPSFLO breaks through the pain points of the market and continuously meets the needs of diversified applications in the chiller market. In the past 20 years, it has focused on the development of reliable and accurate fluid power solutions, and has a number of independent patents. In the future, TOPSFLO will continue to study and bring better products to customers.

The noise source of micro pump and effective solution of noise reduction

With the progress of science and technology, more and more devices have been introduced into people’s life and work. However, the running noise of these devices directly affects the user experience and sense of quality of products. We often encounter customers consulting low noise micro pump, especially in the medical, household appliances and other industries, low noise is an important performance requirement.

So, how can we reduce the noise of the micro dc water pump? This article will analyze noise sources and show effective methods of micropump noise reduction, giving you a more comprehensive understanding of how low noise micropumps are implemented.

1.The noise source of the micro dc water pump

Pump noise is a reflection of the characteristics of the pump working state, and mainly produced by its inner parts or the flowing medium.
From the source, noise is mainly divided into: fluid power noise, electromagnetic noise, mechanical noise, hydraulic noise.
Fluid dynamic noise: When the micro dc pump is working, it continuously generates pulses of fluid pressure, which excites the vibration of the pump body, valves, pipes and other components to radiate noise to the outside world. The test found that the larger the flow of the pump or pump motor running speed is higher, the fluid power noise will be more obvious.
Electromagnetic noise: Electromagnetic noise is mainly caused by the periodically changing radial electromagnetic force or unbalanced magnetic pulling force in the motor, which causes magnetostriction and vibration of the core and winding. Electromagnetic noise is also related to the vibration characteristics of the stator and rotor itself.

Mechanical noise: It is the main source of micro pump noise, produced by the pump internal bearing friction, gasket friction and rotor imbalance impact shaft, etc.
Hydraulic noise: It’s mainly caused by pump impeller blades, cavitation, uneven flow velocity distribution at the impeller inlet, vortex, and surge phenomena.

2.Noise control methods of micro dc water pump

In order to effectively reduce the noise during pump operation, micro quiet water pump products can adopt the following technologies and methods to reduce the noise and vibration during work:

a.Design

For pump noise, there are many related important design points: electronic control scheme, motor design, parts processing accuracy, assembly accuracy, pump head shape design, etc. Among them, the frictional sound influenced by bare pump noise, parts accuracy and the flow sound influenced by pump head design are the main source. After cooperating with the customer’s products, the noise of the whole device and the design of the motor and the electric control scheme are the main ones. The following is a simple analysis of the electronic control scheme, parts accuracy, assembly accuracy.

–Electric control scheme
As there is a switching process in the commutation of the motor, each commutation will cause a vibration of the motor, which is called torque ripple. Field-oriented Control (FOC) scheme can accurately control the size and direction of the magnetic field, making the motor torque stable and improving the noise of the bare pump. At present, both FOC and non-FOC schemes of TOPSFLO can achieve high motor efficiency points in the industry, which is available for customers.

–Parts processing accuracy
All parts that produce relative motion during work will produce friction noise, such as rotor and shaft, rotor and gasket. The dynamic balance of the rotor is a very important factor affecting the noise of the motor. Because the rotor is unbalanced, periodic centrifugal force will occur during rotation, causing vibration and noise. Therefore, the accuracy of the parts must be controlled very precisely in order to effectively control the noise. TOPSFLO adopts imported high-precision ceramic shaft, magnetic quiet rotor, rotor unbalance is much lower than the market average value.

–Assembly accuracy
There are many control points in the pump assembly, such as the coaxiality of the rotor and the stator, the verticality of the shaft, and so on. These, if not well controlled, can cause the same periodic noise as a poor rotor balance. TOPSFLO adopts imported materials and high precision molds to ensure the perfect coordination between components during assembly.

b.Test
The silent room is a noise control measure that uses sound insulation to cover the noise source in a small space so that the noise is rarely transmitted. The shape of the silent room is often designed to be close to the outline of the sound source and installed as close as possible to the sound source. The sound insulation wall of the TOPSFLO silent room adopts a super energy-concentrating sound insulation wall, with a total of 20 layers and a thickness of 400mm. It has all-weather anti-interference ability against external noise and vibration, and provides the best conditions for the shock and noise reduction of the quiet water pump.

c.Installation and operation
Strictly implement the installation procedure during installation to prevent sound sources.
During installation, be sure to use the standard rubber shock-absorbing mounting feet and flexible hoses to connect the pipes, which can effectively slow down the transmission of vibration noise through the equipment chassis and gas pipelines.

In addition, it is possible to reduce mechanical noise by adding sound-insulating materials or boxes to the outside of the pump. It should be noted that some high-power micro-pumps are equipped with heat dissipation, and the heat dissipation part needs to maintain air circulation. When adding sound insulation measures, the heat dissipation part needs to be exposed to avoid overheating and shutdown of the pump.

Pay attention to exhaust (empty) in operation, ensure the allowable suction height or ensure the necessary NPSH, and control the minimum flow of the pump and the overload flow of the pump.

3.Silent micro pump recommendation

TOPSFLO silent water pump series adopts DC magnetic drive three-phase motor, patented silent suspension rotor, and comprehensively uses flow channel optimization and sealing optimization to achieve a noise value of ≤25dB (A), which is 5-10dB(A) lower than the industry average. When running, the sound made by the water pump is softer than the sound of flipping a book, and only slightly higher than the sound of falling leaves. It is very popular with customers in small household appliances, plumbing mattresses, medical beauty and other sub-sectors.

How does TOPSFLO TL-C05 water pump win the favor from the global car heater leader?

In Dec, 2022, good news came from the customer “H company”: TOPSFLO engine preheater water pump TL-C05 has passed UL certification together with the heater equipment of H company, and can enter the market in batches! This means that the products of both parties bring more safety and reliability guarantees to the preheater users, and also represents the opening of a new chapter in the story between TOPSFLO and H Company!

What is the background of H company?
It is a well-known leader in car heaters in the world, headquartered in the United States, with branches all over the world.

What is UL certification?
UL has been established for more than 100 years, and its authority has been well recognized. Especially backed by the huge market in the United States, UL standards have almost become the most important quality indicators in the world. UL is mainly engaged in product safety certification and business safety certification business. Its ultimate goal is to obtain products with a certain level of safety for the market and contribute to the guarantee of personal health and property safety. For manufacturers, UL has the highest recognition in the world and provides the most credible product safety testing and certification.

Then, how does the TOPSFLO engine heater water pump relate to the H company’s engine heater, and passed the UL certification together?

First contact – initial communication needs

The story begins with the first contact between TOPSFLO sales engineer Irina and H company.
It was the day after New Year’s Day in 2016. Irina took the initiative to contact the technical director of Company H to inquire about the need for water pumps. It just so happens that their new generation products is in the research and development stage, and the focus is to break through some technical defects of the original products.

After preliminary communication, Irina learned the water pump they used had the following problems:
1. It’s a AC pump, the efficiency is 2-3 times lower than that of the DC pump, and the volume is large and takes up much space;
2. In the engine system, the liquid containing impurities is easy to cause jamming and wear when passing through the water pump;
3. It is difficult for the AC pump to realize the intelligent control function of the product, such as PWM and FG;
4. The AC pump technical team was not professional enough in support, and the service response was not timely.
In addition to the above problems to be solved, the need for UL certification was also raised.

UL certification is a necessary certification to enter the US market, but it is not a rigid indicator for low-voltage water pumps as components. However, on the basis of having obtained multiple certifications in China, Europe and the United States, TOPSFLO has already made well preparations for UL certification. As long as customers is in need, TOPSFLO team will fully cooperate to help customers realize the verification of the whole machine.

The first-round sample test encountered obstacles

Based on this communication premise, Irina recommended TOPSFLO TL-C01 mini water pump for “H” to test standard parameters.
After testing various performances of the water pump (including flow head, high and low temperature, stalled rotor, power, etc.) by the “H” technical team, it was found that the car water pump needs to be adjusted as follows in order to fully adapt to the new generation heater:
First of all, the pipeline resistance of the heater is relatively large, and a pump with a head pressure of 11M is required, while the standard parameter of TL-C01 is 8M.
Secondly, due to the particularity of the working environment, metal impurities will continuously enter the liquid, causing the relevant contacts of the pump to be stuck or worn.
Thirdly, in order to achieve the purpose of energy saving, high efficiency and environmental protection, the new heater system has a power limit, so the power of the water pump needs to be customized.
Finally, this new heater is an innovation of “H” exsiting product lines, and the functions of automatic signal feedback and intelligent speed regulation need to be added.

The second-round sample test is qualified

Every small adjustment of pump will involve investment in various aspects such as personnel cooperation, development costs, and time cycle, but this is not the point, and the needs of customers are the first for TOPSFLO.
After receiving feedback from “H”, Irina immediately started product optimization work, continuously discussed and verified with the R&D department for three consecutive months, and held several online communication meetings with “H”. In order to achieve the best matching effect with“H” heater, Irina asked “H” R&D team to send the heater system pipeline for testing, and repeatedly debugged the 3D samples, and finally successfully developed the mini water pump TL-C05, realizing a satisfactory customization solution:
1. Based on the large pipe resistance, TOPSFLO R&D team improved the efficiency of the motor, increased the head of the pump and reduced the power at the specified working point, while meeting the performance and power requirements. In fact, this solution is very difficult, because if you want a larger head pressure, you will inevitably increase the power.
How to increase the head pressure while reducing the power?
It requires the perfect matching of the pump structure, motor, electronics and other modules. During this period, TOPSFLO R&D team repeatedly adjusted the customized solution and tested it, and it took a full 15 days and nights.
2. Based on the particularity of the liquid and working conditions, the structure of the key component rotor is customized and molded so that metal impurities can pass through without damaging the pump, and the performance and reliability of the pump will not be affected in any way.
3. Based on signal feedback and speed regulation needs, combined with signal matching,TOPSFLO team helped “H” customize intelligent functions.

After the second sample delivery, Irina finally waited for the good news. According to feedback “H” R&D team, TOPSFLO TL-C05 car water pump has solved the problem that has been bothering them, and impurities won’t damage the water pump. These are problems that have not been solved in the previous water pump.

Hand in hand to pass UL certification

After samples were approved, “H” started formal prototype production, re-matched the test pump samples, and adjusted the structural design of the pump head again to meet the fit and seal with the preheater Auxiliary water pump flow channel, and then began a durable 2-year lifetime test.
At the beginning of 2019, after 3 years, everything was finally verified as qualified, and the purchasing department of “H” issued a trial order for 500 units.
But this is not the beginning of batches. The market still needs the car preheater to meet UL certification before it can be used safely. Then “H” and TOPSFLO responded to the needs of the UL unit, submitted materials, and conducted on-site audits and third-party verification.
In December 2022, the good news finally came that the TOPSFLO car preheater water pump C05 passed the UL certification together with “H” new generation heater!

Climate change may set off a new wave of solar dc pump development

Climate Change Affects All Humanity
Fossil fuels such as gasoline/petrol, diesel, LPG, coal and natural gas power much of the modern world. These materials are burnt to release the energy contained in the carbon atomic bonds, but there are harmful byproducts, a major one being CO2. Increased CO2 levels in the atmosphere act like an insulating layer, trapping heat like a greenhouse, and causing the earth to gradually warm. This occurrence is commonly referred to as Global Warming, and is a key factor behind the Climate Change our planet Earth is experiencing.

Climate change is something that impacts all humans. The effects are many and varied but in general terms it brings more extreme and erratic weather patterns… Things that directly effect the life, safety and prosperity of the human race.

Professional solar water pumps help reduce carbon footprint
Fortunately there is a growing wave of awareness and action to implement technologies and practices to reduce CO2 emissions, and to move the world towards using a more sustainable energy mix. For example, the use of renewable energy sources such as solar, wind, water, biomass, ocean, tidal and geothermal energy is constantly expanding.

Among them, solar energy is widely used all over the world due to its advantages such as absolute cleanliness, no geographical restrictions, convenient access, and high energy quality. Central heating projects have become the main way to sell solar energy, and solar water heaters and solar hot water circulation systems have also entered more and more families. The effect is very ideal for cost control, energy saving and emission reduction.

In solar energy application equipment or systems, circulating pumps are important power components.At present, TOPSFLO has the most professional solar DC circulation pump — TS5 pump, which is an advanced type professionally designed for solar water heating system and solar panel power supply.

TOPSFLO in the production of professional solar pump process, the main materials are:Plastic particles, electronic components, metal parts, ceramic parts, etc., the main production process includes electronic plug-in welding, winding stator assembly, finished product assembly, according to the national intelligent manufacturing development direction of production operations, in the process of industrial production does not produce greenhouse gases, the main source of greenhouse gas generation for the use of electricity.

The TS5 solar water pump is particularly convenient for photovoltaic operation – for solar system loops, the TS5 solar dc pump can be powered directly from the photovoltaic panel. As the sun rises, heat is generated in the solar panels, while electricity is generated in the photovoltaic panels. The main advantages of TS5 solar pumps are:
1. Soft start, easy to work directly with solar panel.
2. High temperature resistance 110 degrees Celsius, automatic over-temperature protection.
3. Brushless magnetic coupling drive, life up to 30,000 hours, continuous operation.
4. Low or no maintenance.
5. All strong materials, system pressure 10bar.
6. Dry-running, locked and polarity and other protection functions.

TOPSFLO Professional Solar DC Pumps are part of a clean energy portfolio and an effective way for ordinary businesses and households to directly reduce their own carbon footprint!

How much CO2 can be saved?
By using renewable energy sources such a Solar Thermal, Solar PV, Wind, Hydro and Geothermal, reliance on fossil fuels can be minimised, thus directly reducing CO2 emissions.
On average, for every 1kWh of grid electricity from non-renewable energy sources, around 0.6kg / 1.3lbs of CO2 is produced, and burning natural gas for water heating produces about 0.185g / 0.4lbs of CO2 for every kWh (not including production and delivery embodied carbon or gas burner efficiency).
In the average household, water heating accounts for around 30% of CO2 emissions. Installing a solar water heater can provide between 50-90% of a household’s hot water heating energy needs, and reduce CO2 emissions by more than 20%. If offsetting electricity from non-renewable sources, installing solar thermal collectors and TOPSFLO professional solar pumps reduces CO2 emissions by approximately 1500kg/3300lbs per year.That is roughly equivalent to planting more than 380 urban trees, or each year driving 10,000 km or 6250 fewer miles in a mid sized modern petrol car.
A solar thermal collector and TOPSFLO professional solar pumps are therefore an excellent way to reduce your household’s carbon footprint.

What are the features of DC water pumps and AC water pumps?

What is a brushless DC mini water pump?

I. Definition of Micro Brushless DC Mini Water Pump
Brushless Mini DC water Pump refers to a machine that uses DC 4.5V ~ 24V to drive a brushless motor to run, and the brushless motor rotation drives the impeller to rotate, thereby increasing the pressure of the liquid to achieve the effect of transferring liquid.
The water pump is generally composed of pump body, motor stator, shaft, bearing, rotor (magnets and impellers) and so on. There are one inlet and one outlet on the pump body, water enters from the water inlet, and exits through the outlet. Any water pump that adopts this form and in small size is called brushless DC mini water pump.
With the development of all walks of life and the progress of science and technology, some customers want to make the pump smaller and lower power consumption, even portable and can be powered by DC. Therefore, miniaturization of water pumps has become an inevitable trend.

II. Principle of Micro Brushless Mini DC Water Pump
Micro brushless DC water pump adopts advanced magnetic drive technology, liquid through the permanent magnet rotor high-speed rotation, static seal design instead of traditional mechanical shaft seal. The liquid is completely isolated from the motor to avoid liquid leakage and improve product life and performance.
The water pump has a built-in frequency conversion brushless DC motor, no need for carbon brush commutation, no mechanical friction and heat generation, low power, and small temperature rise.
The brushless magnetic drive overcomes the inherent defects of the brushed motor and replaces the mechanical commutator with an electronic commutator. Therefore, the BLDC motor not only has the characteristics of good speed regulation performance of the DC motor, but also has the advantages of a simple structure of the AC motor. Reversing sparks, reliable operation and easy maintenance.There is no commutator and carbon brush wear, which reduces mechanical noise and prolongs the service life of the water pump. It is not only related to performance indicators, noise, vibration, reliability and service life, etc., but also involves the manufacturing cost of the product.
At the same time, the brushless DC motor can also accurately feed back the target number of revolutions, torque, etc. Heat generation and power consumption of the motor can be suppressed by precise control.

III. Characteristics of  Brushless DC Mini Water Pump
1. No leakage. Using advanced magnetic drive technology, the stator part and rotor part of the water pump are completely isolated, statically sealed, and leak-free.
2. Long life. It can work continuously for 24 hours for a long time; the service life can reach more than 20,000 hours.
3. Low noise. One-piece injection molded silent rotor is adopted, with low rotor unbalance; imported high-precision ceramic shaft, imported materials and high-precision molds, high-precision control of component size and perfect fit, the noise is 5-10dBA lower than that of water pumps with the same parameters in the market.
4. High temperature resistance. Imported high-temperature food-grade plastic parts are used, which can withstand high temperatures of 100°C for a long time without cracking or deformation.
5. Complete certification. Topsflo pumps have passed multiple authoritative certifications such as NSF, FDA, WRAS, and meet food-grade safety requirements.
6. Customization. With strong research and development strength, water pump products can be customized according to the special needs of customers.

IV. Application range of Brushless DC Mini Water Pump
Micro brushless DC water pumps are widely used in many industries including cooling circulation system, 3D laser printer cooling, battery cooling system, hot water circulation, radiator, heater, water purifier, water dispenser, coffee machine, vending machines, water heaters, water purification humidifier, sweepers, automotive air-conditioning systems, air-conditioning drainage, automotive cooling circulation systems, cleaning equipment, computer CPU cooling circulation, bathroom equipment and many other fields.

7 matters needing attention in the use of brushless DC mini water pumps

The brushless DC pump uses a DC power supply to drive the brushless motor to run. When the brushless motor runs, it drives the impeller to run, so that the liquid in the pump generates pressure and the pressure gradually increases to achieve the function of transferring liquid.

Due to its low price, small size, high efficiency, long life, safety, and quietness,  brushless dc mini water pumps are widely used as functional parts for fluid delivery in various equipment, such as water dispensers, coffee machines, electric vehicles, ,EV charger,solar water circulation system, computer water circulation heat dissipation, refrigeration, medical equipment, cooling system, bathroom products and other fields.

When using a  DC mini water pump, you need to pay special attention to the following 7 major matters

1. Power supply correctly
Use a 12V or 24V DC transformer to supply power, and connect the positive and negative poles of the pump power line correctly. The red power wire of the water pump is connected to the positive pole, and the black wire is connected to the negative pole. The positive and negative poles cannot be reversed, otherwise the pump will be short-circuited and burned.

2. Operate the pump within the allowed voltage range
The water pump cannot be used with excess voltage, and the brushless DC pump should be used within the specified operating voltage range. If the water pump has an over-voltage protection function, when the voltage exceeds the range, the water pump will automatically stop and resume work after returning to the normal voltage range.

3.Strictly forbidden use non-conductive liquid with magnetic particles or impurities.
Ferromagnetic impurities and particles enter the magnetic drive and bearings, which will be adsorbed on the magnet rotor and cause blockage. Impurities and particles enter the pump body and damage the pump. Filtration measures should be taken as far as possible. When transporting media containing solid particles, it should be filtered at the water inlet of the brushless DC pump to prevent impurities from entering the pump and blocking it. Liquids with impurities or magnetically conductive particles are strictly prohibited. Flush in time after conveying the medium that is easy to crystallize or settle (fill the pump chamber with clean water after stopping the pump, and drain it after running for 1 minute), so as to protect the service life of the sliding bearing.

4. Operated at the specified temperature
The water pump should be operated at the specified temperature, and the temperature of the medium is strictly prohibited to exceed the standard, which will easily lead to demagnetization of the magnet and degradation of the performance of the control circuit. A platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve of the magnetic pump to detect the temperature rise in the ring gap area, so as to alarm or stop when the temperature exceeds the limit.

5. Strictly forbidden for the water pump to dry-running
The brushless DC mini centrifugal pump is strictly prohibited from dry-running, because there is no medium lubrication during running, and the rotor will rotate at a high speed, causing its temperature to rise to 200-300 degrees, which is easy to wear the rotor and cause the pump to be stuck. Therefore, you can customize dry running protection to protect the pump motor if there is a risk of running dry for prolonged periods of time.

6. The minimum pipe diameter is not smaller than the inlet and outlet
Ensure that the minimum pipe diameter in the pipeline is not smaller than the inner diameter of the water inlet and outlet. If it is less than that, the pressure of the water pump cannot be released normally, so that the rotor of the water pump rotates at a high speed, and the noise is large. On the one hand, it will also reduce the life of the water pump.

7. Installed below the liquid level
The brushless DC water pump is a centrifugal pump, which cannot automatically exhaust air or self-priming, and must be submerged or installed below the liquid level when in use (the liquid can flow in automatically when the pump is not working).

How to select the water flow rate of laser chillers pump ?

In the selection method of the laser chiller, the water flow and head of the chiller will directly affect the stable operation of the laser chiller in the future.

1) The flow rate of the chiller water pump is too small:

The direct effect of too small flow rate of the water pump is that the heat cannot be quickly taken out from the cooled equipment, causing the temperature of the cooled equipment to rise. And because the cooling water flow rate is not fast enough, the temperature difference between the inlet and outlet becomes larger, so the surface temperature difference of the temperature-controlled equipment is relatively large.

2) The chiller water pump flow rate is too large:

The large flow rate of the water pump makes the cooling effect of the chiller good and the cooling capacity large, which can meet the cooling requirements. However, an excessively large cooling water circulation pump will inevitably increase the equipment cost of the industrial chiller, and the operating cost such as electricity will also increase. The high cooling water flow and pressure will also increase the resistance of the water flow pipe, which will cause unnecessary energy consumption, reduce the service life of the cooling water circulating pump, and may cause many other failure

Application of micro diaphragm pump in inkjet printing industry

Background Introduction
Inkjet printers, which are used to spray ink droplets onto a printing medium to form words or images.
There are two main types of inkjet printing technology: continuous inkjet (CIJ) and on-demand inkjet. Continuous inkjet technology is mainly used in industrial and professional printing systems. On-demand inkjet is a random inkjet system in which ink is sprayed only when printing is needed, which has a relatively wider application range.
Regardless of the type of inkjet printer, professional inkjet technology requires the perfect combination of all technical components to achieve the perfect printing effect.In order to achieve this goal, the micro diaphragm pumps plays a vital role.

The roles of diaphragm pumps in inkjet printing equipment
– To vacuum and pressurize the feeding system;
– Conveying water and solvent-based inks;
– Refill ink container;
– Remove excess ink from the print head and remove ink-breaking material for the storage tank;
– Clean the print head and ink drain system.

The application difficulty of diaphragm pump in inkjet printer
1. Continuous inkjet (CIJ) process uses a pressure pump to pump the ink jet into the nozzle. If it is continuous inkjet printing, the operation time is longer, the air pump needs to be in the working state for a long time, and the pump life requirements are higher.
2. Inkjet needs stable pressure, which requires the pressure system to maintain stable pressure when working for a long time. It has high requirements on pump durability, stability and reliability.
3. Different ink components may contain additives that will decompose diaphragms, connectors or pipes and other parts of the pump, which puts a high requirement on the chemical resistance of the pump’s materials.
4. Because the ink solvent is volatile and flammable, there are safety risks, and the pump is required to run without sparks and static electricity.

TOPSFLO micro diaphragm pump series solutions
TOPSFLO TM30, TM40, TF30 series diaphragm ink pumps are durable and reliable, can ensure maintenance-free continuous operation in arduous inkjet printers:
1. Lifetime up to 15,000 hours: independent design using high-performance coreless brushless motor, high quality rubber material of high purity and good wear resistance, long service life and maintenance free.

Analysis on the Principle, Structure and Application of Pump of Biochemistry Analyzer

Biochemical diagnosis is the earliest automated detection method, and it is also one of the most commonly used in vitro diagnostic methods. Biochemical diagnosis is often used for basic examination items such as liver function, kidney function, blood sugar and lipid. It is used in combination with biochemical diagnostic reagents and biochemistry analyzer to determine whether the human body is in a healthy state by measuring the content or activity of specific biochemical substances.

The currently commonly used automatic biochemical analyzer is a biochemical analysis instrument that automates the steps of sampling, adding reagents, mixing, heat preservation reaction, detection, result calculation and display, and cleaning in the analysis process. Due to the high degree of automation and the functions of calibration and automatic correction, the subjective error and system error are relatively small and easy to use.

•Working Principle

The colored liquid in the cuvette is irradiated by multiple vertical monochromatic beams;
Through the absorption of light energy by the measured sample, the light signal is converted into a corresponding electrical signal by the photoelectric converter;
The signal is amplified, rectified, and converted into a digital signal, which is sent to the computer;
Computer-controlled drive electric drive filter wheel and sample tray;
Then the measurement data is processed, calculated, analyzed and saved according to the working mode selected by the user;
The printer prints the corresponding results simultaneously;
After measuring each set of samples, the cuvette was cleaned.

Basic Structure

Structurally, the automatic biochemistry analyzer includes sampling system, reagent system, reaction system, cleaning system, pipeline system, colorimetric system, computer system, etc.

1. Sampling system: it is the key device for adding quantitative samples (usually microscale) and reagents to designated cuvettes for reaction. The dispensing and sampling device is mainly composed of syringe, stepping motor or transmission pump, sampling arm and sample probe, etc.

2. Reagent system: it generally consists of a reagent storage device and a dispensing&liquid filling device. The dispensing&liquid filling device is similar to the sampling system. The reagent probe can often pre-warm the reagent. The initial amount of the reagent 2 (R2) probe in the dual reagent system should be relatively low in order to match reagents with different R1/R2 ratios.

Reaction system: reaction cuvettes are mostly in the form of a turntable. During the reaction measurement process, the sample loading arm, the liquid loading arm, the stirring rod, the optical path and the cleaning device are rotated according to a fixed program. The biochemistry analyzer uses a temperature control device to keep the incubation temperature regulated and constant.

Cleaning system: Probes and stirring rods are automatically flushed by means of torrent. The cleaning device generally consists of a suction needle, a discharge needle and a wiping brush. Generally speaking, after aspirating the reaction solution, the instrument is first rinsed with alkaline solution, then with acidic solution, and finally with deionized water for three times.

Computer system: The computer is the brain of the automatic biochemistry analyzer. The injection and identification of specimens and reagents, barcode identification, constant temperature control, flushing control, result printing, quality control monitoring, and alarms for various instrument failures are all performed by the control of computer.

Application of  Biochemistry Analyzer Pumps

In a biochemistry analyzer, micro medical pump is a common fluid-driven component that has multiple functions such as sample transmission, reagent cooling, deionized water circulation, temperature control system cooling, waste liquid removal, and probe cleaning.

As a precision medical equipment, biochemistry analyzer has very strict requirements on the performance of Direct Drive pumps, and also have high requirements on the cleanliness of equipment pipelines, it must without impurities and particles being precipitated, and without any pollution. In addition, biochemistry analyzers are generally used in hospitals and other places, which have very high requirements for noise and vibration.

Laser Chiller Water Pump

The laser chiller is a cooling device for cooling the generator of laser equipment by water circulation. It can control the temperature of the laser generator and maintain the normal operation of the laser generator for a long time. It is an indispensable and important part of the operation of laser equipment.

The working principle of the laser chiller is to inject a certain amount of water into the chassis, the cooling system cools the water, and then circulates the cooling water to the laser equipment through the coolant pump to achieve the purpose of cooling. Among them, the laser cooling circulation pump plays an important role as the heart of the system, and its main functions are:

1. Promoting the circulation of cooling fluid to realize that excessively high operating temperature of the laser tube will cause irreversible damage and weaken the laser output power. The service life of the laser tube will also be greatly shortened.

2. Provide large and stable flow and head to maintain the performance of the chiller. The water circulation is unstable or the head is too small, which will easily cause poor heat dissipation of the laser chiller module and Q head, and easily cause dirty blockage, which directly affects the performance of the laser chiller. and service life.

Topsflo Battery Cooling Water Pump Effectively Solves the Safety Problem of Energy Storage System

New energy storage, as an important measure to improve the regulation ability, comprehensive efficiency and security capability of the energy power system and support the construction of the new power system, which is one of the key supports for carbon neutrality in the energy field. However, the frequent safety accidents of energy storage power stations in recent years are anxious, and the thermal management of energy storage is very important.

The energy storage industry will enter the fast lane of development

In recent years, PV and wind power and other new energy power generation has developed significantly, but the development of the energy storage industry has not kept up. The ratio of storage to new energy has gradually declined in recent years. In 2020, China’s new energy storage ratio will be about 6.7%, which is significantly lower than that of other countries and regions outside China. 15.8% reserve ratio.

Since 2020, various provinces in China have introduced relevant policies to encourage or mandate new energy supporting energy storage, stipulating that the proportion of new energy power side allocation and storage is 5%-20%. On August 2022, the National Development and Reform Commission and the Energy Bureau clarified that 15% of the power of peak-shaving resources (20% is preferred), and more than 4 are required to be equipped with peak-shaving capabilities.

On July, the National Development and Reform Commission and the National Energy Administration issued the “Guiding Opinions on Accelerating the Development of New Energy Storage”, with the goal of achieving carbon peak and carbon neutrality. By 2025, new energy storage will be realized from the initial stage of commercialization to large-scale The development will turn, and the installed capacity will reach more than 30GW; by 2030, the comprehensive market-oriented development of new energy storage will be realized, the technological innovation industry will rank among the top in the world, and the installed capacity will basically meet the corresponding needs of the new power system.

Recently, China Southern Power Grid issued the “14th Five-Year Plan for Power Grid Development” and proposed that during the “14th Five-Year Plan” period, the construction plan of China Southern Power Grid will invest about 670 billion RMB in order to speed up the construction of digital power grids and the process of modernizing power grids, and promote new types of power with new energy as the main body. In terms of system construction, in the field of energy storage systems, 20GW of new energy is proposed, and the ratio of new energy storage in China Southern Power Grid is nearly 20%.

Safety issues are the core issues of energy storage power stations

In recent years, safety accidents of energy storage power stations have occurred from time to time, which has aroused strong social concern. On April 2021, an explosion occurred at the Beijing Guoxuan Fuweisi Solar Energy Storage Power Station, resulting in the death of two firefighters. On July, an energy storage system in Victoria, Australia, detonated. Four days after the fire, the local government was still trying to contain the fire.
From 2011 to April 2021, there have been 32 fire and explosion accidents in energy storage power stations around the world. Especially in South Korea, under the incentives of policies, the construction of energy storage projects has exploded. There have been major safety hazards on the one hand, and 24 safety accidents have occurred since 2017.

Thermal management is an important guarantee for energy storage safety

Among the above 32 fire and explosion accidents of energy storage power stations, 66% (21 cases) of fire and explosion of energy storage power stations mostly occurred during charging or resting after charging. The battery is in an overcharged state, and the voltage rises to form an internal short circuit, resulting in local thermal runaway, which leads to spontaneous combustion and fire.
This shows the importance of thermal management for the safety of energy storage power plants. The energy storage system must be equipped with a temperature control system with sufficient strength and flexibility to ensure the safe and stable operation of the power plant.

TOPSFLO battery cooling water pump protects the safety of energy storage

A good temperature control system needs a high-quality cooling water pump to support it. TOPSFLO is the supplier of the battery energy storage system (energy wall) of “T” Company in the United States, and has related battery cooling system water pump solutions.

The Story of the Cooperation Between Topsflo and the World Dental Autoclave Brand

Started from good reputation of Topsflo
Long and stable cooperation from Topsflo’s consistent and reliable pump quality

In 2015, RE, the world’s leading company, took the initiative to find Topsflo’s pre-sales engineers.

It turned out that RE was developing an autoclave sterilizer at that time, which was designed and implemented to ensure the safety of staff, patients, instruments and the working environment. The design has taken shape and requires a high-quality dc water pump that is small in size, low in noise, and resistant to high temperatures.

At this time, Topsflo, as a R & D manufacturing enterprise of micro pumps in China, has a good reputation among overseas brand customer groups, so it has attracted customers to come to consult on their own initiative.

After a preliminary contact of the Topsflo, RE Company conducted the first water pump sample test, mainly for the performance of the pump flow, head, power, noise, temperature rise and so on. In the noise link that customers attach great importance to, TOPSFLO micro brushless DC water pump TL-B03 performs well, with noise as low as 35dB(A)/0.5M, which is 5-10dB(A) lower than ordinary water pumps in the market. The customer is very satisfied with the results of the first sample test.

Subsequently, the customer purchased a small batch of samples again for long-term stability testing. After a period of rigorous testing, customers reported that the performance of Topsflo TL-B03 far exceeds expectations in terms of long-term high temperature resistance, working life, and noise batch consistency.

The seemingly easy-to-pass sample test actually condenses the wisdom crystallization of the ten-year painstaking research of the Topsflo R&D team. Topsflo keeps improving the raw materials and structure, constantly overcoming technical difficulties and improving performance, so that TL-B03 satisfies customers in the test.

What has changed is the demand and standard
What remains unchanged is the beginner’s mind

The recognition of RE Company started the formal cooperation between the two parties.

During the seven years of cooperation since then, with the upgrade of autoclave products, the customer’s demand for water pumps has continued to increase, but at the same time more and more stringent requirements have been put forward. Over the years, Topsflo pumps has witnessed the growth of RE’s autoclave project and technology updates. At the same time, RE has also expressed high appreciation for the batch consistency of Topsflo pump, communication services, and delivery capabilities.

In particular, the high batch consistency of the Topsflo mini dc water pump has become a strong backing for RE’s autoclave upgrade.

The high batch consistency of products must be based on the overall strength of a company, not just a certain aspect can be achieved. The company’s hardware is in place, the raw materials are better, the precision is better, the production control ability is better, and the quality control is better… Only when every detail is ensured, the final batch consistency will be guaranteed, and the high-quality water pumps with stable quality will be provided to our customers.

We know that in this industry, it is not difficult to make a good pump, but it is not easy to ensure that the 10,000 or 100,000 pumps provided to customers are of the same high standard. Guaranteeing high-volume consistency of products is not only a manifestation of the “artisan spirit” of Topsflo as a manufacturing enterprise, but also a commitment of Topsflo to customers, and it is also the persistent pursuit of high-end quality made in China!

Since cooperating with RE company on the autoclave, Topsflo has only received one complaint: the customer reported that the label of one of the pumps was not properly affixed. Other than that, the customer is particularly satisfied with the product quality of Topsflo dc water pumps, and said that the upgraded products will still use Topsflo water pumps!

On the other hand, Topsflo’s delivery ability also makes customers invincible in the process of attacking the market!

Topsflo does not fight unprepared battles. In order to meet the growing order demand of RE Company and let customers have no worries in the process of expanding the market, Topsflo makes predictions according to customer orders and purchases preparation materials in advance, even if in the case of global shortage of electronic components, it can also ensure that the products are delivered on time and in quantity.

Time has lived up to expectations, witnessing the ingenuity and quality of Doppler. High-quality water pumps have enhanced the brand power of customers, and the brand power of customers and the increasing order volume have injected stronger market vitality into Doppler.

From the first satisfied test and seven year’s stable cooperation to the future expectation, customer satisfaction and trust is the direction of our efforts, and it is our consistent original intention!

Optimized Design Alignment and Fluid Dynamics Study for Automotive Electronic Water Pumps

1.1 Analysis of Vehicle Thermal Management Requirements

The drive system of a vehicle comprises the drive motor, motor controller, and reducer. These components generate significant heat during operation, particularly under heavy loads. If the temperature rises too high, it can negatively impact motor performance, potentially causing damage or failure. Similarly, excessive temperature in the high-speed reducer’s lubricating oil can reduce its viscosity, compromising the lubrication effect. For electric vehicles, the lithium-ion power battery also generates heat during charging and discharging, especially during fast charging or high-power discharge. If the battery temperature becomes too high or low, it can affect both its lifespan and performance, and in extreme cases, lead to spontaneous combustion. Additionally, components like chargers, inverters, and DC transformers require effective cooling. This study focuses on the cooling needs of the drive system and power battery, with an in-depth analysis of the vehicle’s electronic water pump.

1.2 Cooling System Structure

Based on current research into electric vehicle cooling systems, this paper proposes the use of water cooling to regulate the temperature of the drive system and power battery. As illustrated in Figure 1, the vehicle’s cooling system is designed with one “large cycle” and two “small cycles.” In addition to the conventional water-cooling circuit that manages the temperature of the vehicle’s core components, the air-conditioning system within the passenger compartment is also integrated into the vehicle’s thermal management system. This enhances or shares the thermal load within the overall cooling cycle, ensuring efficient heat distribution and improved system performance.

2. Electronic Water Pump Scheme Design

The hydraulic and mechanical design of the electronic circulation water pump for vehicles closely resembles that of traditional mechanical water pumps, with the primary distinction being in the motor and its controller. Unlike mechanical pumps, the speed of the electronic water pump is decoupled from the engine’s speed and is instead controlled through precise matching control commands. Given the similar design and development processes for electronic water pumps used in both power battery cooling systems and drive system cooling systems, one of these applications can serve as the focus for research. In this case, the electronic coolant pump used in the drive system cooling is selected for analysis.

The vehicle’s electronic water pump comprises three main components: a centrifugal water pump, a brushless DC motor (BLDC motor), and a motor controller. The impeller of the water pump is integrated directly with the motor shaft, resulting in a compact design with minimal mechanical losses. The motor’s rotor drives the impeller, which draws the coolant in from a vertical direction and forces it against the inner wall of the pump’s volute. This process propels the coolant through the system, transferring both energy and fluid to the next stage in the cooling cycle.

Application trend of automotive electronic water pump technology

As a key component of the automotive thermal management system, the electronic water pump plays an important role in the intelligent control of the temperature of the automotive subsystems, ensuring the safe and reliable operation of the subsystems, and reducing energy consumption. This paper introduces the basic structure, principle, advantages and disadvantages of mainstream electronic water pumps, analyzes its different application requirements in major systems such as internal combustion engines, new energy pure electric vehicle drive systems, and power battery thermal management, and analyzes the application and technology of electronic water pumps. Development trends are inferred.

Electronic water pump is a key component in the automotive cooling system. It is mainly used in the main cooling system of the internal combustion engine, the turbocharger cooling circuit and the air intake intercooling system. It is also used in the drive system of new energy vehicles and the thermal management system of the power battery. The use of intelligently controlled electronic water pumps in the above systems can enable the temperature of the cooling system to be closed-loop controlled according to real-time working conditions, and reduce energy consumption while ensuring the reliability of the cooled components.

1 The mainstream structure, principle and advantages and disadvantages of electronic water pumps
The electronic water pump is composed of three basic parts: hydraulic machinery, motor and motor controller. According to its fluid sealing structure, it is mainly divided into dry type and wet type electronic water pump. The hydraulic mechanical part and the motor part of the dry electronic water pump are separated independently and connected by a shaft. The water pump and the motor are sealed and isolated by rotating dynamic seals. The motor casing, water pump casing and motor controller casing are connected as a whole, and the motor drives The impeller of the water pump rotates. The wet electronic water pump is designed with a sealed thin-walled bushing between the rotor and the stator of the motor, and the rotor of the motor is integrated with the impeller of the water pump. When working, the rotor of the motor is immersed in the fluid medium, the magnetic field generated by the stator coil penetrates the thin-walled bushing and the magnetic field of the permanent magnet of the rotor forms a loop, driving the rotor and impeller to rotate, and the motor controller is installed next to the motor.

2. Application of electronic water pump technology in internal combustion engines
2.1 Application of internal combustion engine main cooling water pump
At present, the main cooling water pump of most internal combustion engines is a mechanical pump, which is installed at the front end of the engine. The driving force is provided, and the water pump and the crankshaft rotate synchronously according to a fixed transmission ratio. The disadvantage of this design is that the speed of the water pump can only rise and fall synchronously with the speed of the engine. When the engine needs to warm up quickly at low temperature, it does not need a large coolant flow, but the water pump cannot run at a low speed. However, when the engine is under low-speed and high-load conditions, a large flow of liquid cooling is required, and the water pump cannot run at high speed at this time. When driving at low load and high speed, the air cooling effect is good, and a large coolant flow is not required, but at this time the water pump is running at high speed. In order to ensure a reliable cooling effect under special working conditions such as low speed and heavy load, the mechanical pump must be designed with relatively high power. However, under most non-special working conditions, the pump operates with excess power, resulting in unnecessary energy consumption.

Because of these deficiencies in mechanical water pumps, electronic water pumps are gradually being applied to the main engine cooling system. The speed of the electronic coolant pump is no longer directly related to the engine. The electronic control unit (ECU) collects parameters such as engine speed, load, and water temperature through sensors, and compares them with the calibrated optimal water temperature under corresponding working conditions to control the water pump speed. Realize closed-loop control of liquid temperature. Its advantage is that it can control the operating temperature of the engine in the optimal range, thereby improving the thermal efficiency of the engine and reducing fuel consumption, while achieving rapid warm-up under low temperature conditions. The speed of the electronic water pump is independently controlled, and it does not need to run at full power when it is not the maximum cooling demand. The maximum power and average operating power of the electronic water pump are much lower than those of the mechanical water pump.

The power of the electronic water pump is mainly distributed between 50 and 600 W. For cars equipped with ordinary generators and ordinary 12 V batteries, the power consumption and current of this power section are still too large. The electric energy that drives the water pump is generated by the generator driven by the engine, and the multi-stage conversion of energy brings about a large loss of efficiency. And because the electronic water pump involves technologies in multiple fields such as electronics, software, motors, and hydraulic machinery, it is very difficult, and the failure of the water pump will also lead to serious consequences of engine damage, so its reliability is extremely high. Previously, only a few international auto parts companies had mature technologies and products. These factors made the application cost of the main cooling electronic water pump very high and it was difficult to popularize it.

As cars become more efficient at recovering energy to generate electricity during braking, the recovered electricity is most suitable for driving accessories such as water pumps. After years of research and development, some auto parts companies have also launched a series of cost-effective electronic main water pump products, which are now supporting mainstream auto manufacturers. After solving the power consumption and cost problems of the water pump, the electronic water pump for main cooling of the engine will quickly become popular due to its unique advantages.

2.2 Application of electronic water pump in turbocharger cooling circuit
Due to the high-temperature exhaust gas and high-speed rotation of the turbocharger, the temperature at the turbine end will reach above 600°C, while the working temperature of the sealing ring needs to be controlled below 230°C, and the bearing needs to be controlled below 150°C, otherwise the turbocharger will be damaged quickly , so efficient cooling is key. Turbochargers are generally designed with a liquid cooling circuit, but after the engine stops, the mechanical main water pump will also stop working. Without cooling of the circulating liquid, heat soaking will cause damage to the bearings, shafts and seals of the turbocharger. To solve this problem, a 15-30 W auxiliary electronic water pump is generally configured in the turbocharger cooling circuit to continue to provide cooling for the supercharger after the engine is shut down.

2.3 Application of electronic water pump in air intake intercooling circuit
Due to the high-temperature heat conduction at the turbine end of the turbocharger and the heat generated by the compression of the air, the temperature of the air passing through the turbocharger compressor can reach 150°C, while the temperature of the air entering the engine should generally be controlled below 50°C. Compressed air is used to cool the air, and the current mainstream technology uses liquid cooling plus air cooling to cool the intake air. In a supercharged engine equipped with a mechanical main water pump, a small electronic water pump of 30-60 W is often configured in the liquid cooling circuit of the intercooler to control the intake air temperature. The electronic water pump is used in the air intake and intercooling system, which can solve the cooling demand of the turbocharger through the layout of the pipeline. In engines using external exhaust gas recirculation (EGR) technology, the liquid cooling circuit of the EGR cooler is generally connected in parallel with the intake air intercooling circuit to achieve exhaust gas cooling.

2.4 Internal combustion engine thermal management system based on electronic water pump
After the engine uses the electronic main water pump, it can realize the shutdown cooling function. On this basis, the thermal management system is equipped with an electronically controlled valve group that can control the flow direction and flow of the cooling circuit, so as to realize the matching of the needs of each cooling circuit, and does not need to be equipped with multiple The water pump can better meet the thermal management needs of various parts of the engine. At present, General Motors has used this technology on the CSS series of new engines. However, its thermal management system and electronic water pump are designed and arranged separately and connected by pipelines. The integrated design of pump and valve can save installation pipelines, optimize layout space and reduce pipeline interfaces, which is conducive to cost reduction. It will become the development trend of engine thermal management technology in the future.

3 Application of electronic water pump technology in new energy electric vehicles
The application of electronic water pumps in electric vehicles is mainly the liquid cooling circuit of the drive system and the liquid cooling circuit of the power battery. The drive system includes a drive motor, a motor controller and a reducer. The drive motor generates a lot of heat when it is running under heavy load, and the high-power device IGBT in the motor controller will also generate a lot of heat. Excessive temperature will reduce the efficiency of the motor and electric control. drop, temperature runaway can lead to serious consequences of rapid burnout. In order to ensure good lubrication in the high-speed reducer, it is also necessary to control the temperature of the lubricating oil through the heat exchanger. Therefore, the driving system is generally designed with a liquid cooling circuit, and the temperature of the cooling liquid is generally required to be controlled within 90°C. The general power of the  small electronic coolant pump used in this system is 40-60 W.

The lithium-ion power battery of an electric vehicle will generate heat during charging and discharging, especially during fast charging and high-power discharging. The discharge performance and cycle life are reduced, and thermal runaway may also cause the power battery to spontaneously ignite. Therefore, the power battery is designed with a thermal management system of liquid circulation. In the liquid circulation circuit, there is a heat exchanger for heat exchange with the air conditioning system, an electric heater for heating the liquid, and an electronic water pump to drive the liquid circulation, which can realize the power battery. The temperature of the power battery is controlled at 10-55°C, the temperature of the liquid in the battery thermal management system is generally lower than 50°C, and the power of the mini electronic water pump is generally 50-120 W.

There are also components such as chargers, inverters and DC transformers in electric vehicles, which also need to use liquid cooling systems. Due to the large difference in the control temperature range of the drive system and battery thermal management, the same cooling system cannot be used, so more than two electronic water pumps are generally used. The difference between the electronic water pump used for electric vehicles and the electronic water pump used for internal combustion engines is that the temperature of the working medium of the internal combustion engine water pump can reach 120 °C, and the ambient temperature can reach 150 °C, and its high temperature reliability requirements are extremely high. The electric vehicle water pump not only needs to work when the car is running, but also during the charging process, and its service life is required to be higher.

TOPSFLO High-Power Liquid-Cooled Charging Cable Pump Enables Safe and Fast EV Charging

As the “fuel stations” for electric vehicles, the charging times for EV chargers are considerably longer compared to traditional refueling. With sales of new energy vehicles continuing to rise, concerns over battery life and the availability of charging stations—especially during peak periods like holidays—are becoming more common. The viral news story about a Tesla driver stuck in traffic during the recent National Holiday, unable to reach a charging station and requiring a tow truck due to an empty battery, sparked widespread discussion.

Compared to the sluggish charging speeds of “low-flow” chargers, fast-charging EV chargers are much more attractive to consumers. To keep up with the increasing demand for faster charging, the output power of EV chargers must be scaled up, which in turn raises the heat flow density within the system. This presents significant challenges to the safety and efficiency of the charging system.

A crucial solution to this issue is the use of liquid cooled EV charger pumps. When manufacturers choose water pumps for their new energy vehicle charging piles, they must ensure that the pump maintains high reliability, long service life, quiet operation, and resistance to water and dust in extreme temperatures (ranging from -45°C to 80°C). It should also provide multiple safety protections and intelligent controls.

The role of  EV fast charger pumps in electric vehicle charging systems can be broken down into two main areas:

–Liquid Cooling Modules
In the DC fast-charging system, the liquid cooling circuit consists of several cooling modules. A circulating pump and a diverting valve are used to distribute coolant evenly across these modules. The design of the internal pipes in the cooling module depends on the position of the heating components in the charging pile, with the coolant circulating through cold plates to absorb and dissipate heat.

–Liquid-Cooled Charging Cables
These specialized cables are designed to handle high-current charging applications. A cooling channel runs between the cable and charging gun, with coolant circulating to absorb heat. The liquid cooled EV charger pump drives this circulation, efficiently removing excess heat from the system. For example, Tesla’s V3 supercharger, introduced in March 2019, uses a liquid-cooled charging cable that is about 44% smaller in diameter than its V2 counterpart (23.87mm). This upgrade allows the V3 supercharger to deliver a maximum peak power of 250kW.

The EV charger cooling pump is essential for managing the heat dissipation needs of high-power chargers, minimizing heat-related damage to components such as the charging gun, cable, and charging pile.

TOPSFLO has been a leader in the development of cooling systems for charging piles. The company’s DC EV charger pumps offer numerous advantages over standard pumps, including compact size, excellent cooling performance, resistance to both high and low temperatures, long lifespan, and maintenance-free operation. Additionally, these pumps are designed with intelligent control systems and can be customized to meet specific customer requirements, including electromagnetic compatibility (EMC) solutions.

Each liquid cooled  fast EV charger pump by TOPSFLO undergoes comprehensive high and low-temperature fast-switching tests, ensuring that it performs reliably in the extreme conditions of supercharging stations. TOPSFLO pumps use high-quality electronic components from renowned international brands, ensuring reduced heat generation and exceptional reliability. Additionally, TOPSFLO’s brushless DC charging pile pumps feature 5V/PWM speed regulation and FG feedback signals, allowing for automatic detection, real-time data feedback, and failure alarms to protect high-performance liquid cooling systems in supercharging piles.

As a vital part of the new energy vehicle infrastructure, charging piles have gained significant national policy support and are growing rapidly in response to rising market demand. With nearly 20 years of expertise, TOPSFLO focuses on the development and manufacturing of brushless DC water pumps, leveraging cutting-edge technology to support the global shift toward electric and intelligent vehicles, and driving innovation in the development of liquid cooled EV charger pumps.

Application of food grade water pump in intelligent water dispenser

Water as one of the three main elements of human survival, no one can leave it. 50% ~ 60% of the body weight is composed of water, the water in the children body is even higher than 80%. It can be said that there is no life without water. With the improvement of people’s living standard, consumers have higher requirements for drinking water. Intelligent water dispenser also gradually enters people’s vision. So do you know how the smart water dispenser discharge water quickly? Next, the editor will explain the application of food grade water pumps in intelligent water dispenser.

What is an intelligent water dispenser ?

Intelligent water dispenser, as the name implies, is intelligent control of the water dispenser, also known as intelligent drinking table, intelligent boiling water system, intelligent water boiler and so on. This is different than ordinary bottled water products. It filters impurities in tap water through a filter, and then heats it to meet drinking standards. This smart application saves time and electricity, and deeply loved by people.

Function of Water Pump in Intelligent Drinking Water Dispenser
The water inlet of the intelligent water dispenser is connected with a water pipe, which finally reaches the standard of human drinking water through layer filtering, heating or cooling. After so many filtration and dilution, the pressure in tap water has already been reduced. When the drinking water reaches the water outlet, the pressure is already very weak, which directly affects the volume and speed of the water. Therefore, it is necessary to install a food grade water pump to pressurize the water to make drinking easier and more intelligent. This is the principle and effect of pressurization of food grade water pumps.

Features of  food grade water pump:

1. Food grade approved. All food water pumps have passed WRAS and FDA food certification, FDA is recognized as one of the largest food and drug regulatory agencies in the world with strict requirements; WRAS is a UK certification for drinking water safety.

Topsflo’s Liquid Cooling Energy Storage Electronic Water Pump Empowers Home Energy Storage Safety

The liquid cooling energy storage industry has been closely watched recently, and some institutions predict that the market space of liquid cooling energy storage will explode by 25 times in four years. What is liquid cooling energy storage? What are the components? What are the characteristics? Topsflo engineers will explain it to you in detail.

Thermal runaway accidents of energy storage occur frequently

To understand liquid cooling energy storage, it is necessary to start with energy storage temperature control technology. Liquid cooling energy storage is a type of energy storage temperature control technology.

Energy storage temperature control is the key to preventing the capacity decay, life shortening, and thermal runaway of the energy storage system. The energy storage system has a large number of batteries, large battery capacity and power, and requires effective battery thermal management. Otherwise, it may lead to a decline in battery charge and discharge performance, capacity, and life, or even lead to thermal runaway, resulting in safety accidents.

From 2011 to 2021, a total of 32 energy storage power station fires and explosions occurred around the world. From January to May 2022, more than 10 energy storage fire accidents have occurred around the world. Thermal runaway of batteries has become the main cause of fire accidents. Frequent fire incidents highlight that energy storage temperature control has become an essential and important component to ensure the safe operation of energy storage power plants.

Liquid cooling is the long-term trend of energy storage temperature control

Energy storage temperature control mainly includes air cooling, liquid cooling, heat pipe cooling, phase change cooling and other technologies. Among them, air cooling is to take away the heat in the energy storage system in the form of air convection, and liquid cooling is to take away heat by using liquids such as water and ethylene glycol as the heat transfer medium. Phase change cooling and heat-pipe cooling are currently less practical and are still in the laboratory stage.
The basic components of the liquid cooling system include: liquid cooling plate, liquid cooling unit (heater optional), liquid cooling pipeline (including temperature sensor, valve), high and low voltage wiring harness, coolant, coolant water pump, etc.

On the whole, liquid cooling has higher heat dissipation efficiency and heat dissipation speed, and can better control the temperature difference between batteries. Therefore, its energy consumption is lower and the system life is longer, thereby helping the energy storage system to reduce the cost of the whole life cycle. Although the current domestic energy storage thermal management is still dominated by air cooling, under the trend of high-capacity and high-rate energy storage, liquid cooling solutions are more suitable for high-temperature or large-capacity scenarios. In the future, as the demand for energy storage stations with larger battery capacity and higher system power density, such as new energy power stations and off-grid energy storage, starts, it will promote the industry to adopt more liquid cooling solutions.

5 essential features of high-quality energy storage electronic pumps

The energy storage liquid heat dissipation solution needs to drive the liquid in the pipeline to circulate through the electronic water pump, take away the performance of the excess heat of the battery system, and achieve the best working temperature conditions of the battery pack. Therefore, the electronic water pump, as the core component of liquid cooling, is very important.

So, what are the characteristics of high-quality energy storage electronic water pumps?

First, longer life. Long-life pumps help reduce operating costs and increase the life of the energy storage system. Topsflo pumps use high-efficiency brushless DC motors, imported chips, and high-precision silent rotors, with a lifespan of 30,000 hours, which is much higher than that of ordinary pumps on the market.

Second, the temperature rise is lower. More than 90% of Topsflo pump parts and electronic components are from world-renowned brands, automotive grade electronic components, uniquely designed PCB boards, sufficient margin design for electronic solutions, low temperature rise, fast heat dissipation, The cooling effect is remarkable.

Third, the temperature range is wider. Liquid-cooled energy storage pumps must have the ability to work normally in outdoor conditions. Each Topsflo water pump has undergone strict high and low temperature fast switching tests of the whole machine, and can run stably under -40°C low temperature conditions.

Fourth, the security level is higher. The safety level of the water pump is related to the safety of the energy storage system and should not be underestimated. Topsflo pumps have six safety protections including idling protection, locked rotor protection, overcurrent protection, polarity protection, overvoltage protection, and constant power output, escorting high-efficiency liquid-cooled energy storage systems.

Fifth, the reliability is higher. The liquid-cooled energy storage system requires the water pump to have the ability to run stably for a long time, and has extremely high requirements on the reliability and stability of the water pump. Topsflo has four laboratories that meet the standards of CNAS national laboratory accreditation, equipped with international advanced testing equipment, and carries out reliability verification stricter than industry standards, and has passed CQC quality certification, CE, RoHS, REACH, WRAS, FDA, NSF and other international certifications, to provide customers with pumps with stable performance and excellent quality.

Temperature control plays a crucial role in the safety and economy of energy storage systems. As a long-term trend, liquid-cooled energy storage will have great potential. That’s it for the introduction of liquid-cooled energy storage electronic water pumps. Topsflo Pump looks forward to working with more energy storage companies to jointly promote the sustainable development of the industry!

TOPSFLO pumps meet the rigorous cleanliness standards required in the IVD industry.

RV BLDC Booster Pump

Life is originally plain, but running will be windy. The long years are no longer than the mountains along the way, and it is nowhere near the footsteps of moving forward. Yearning for poetry and distant places, and do not want to give up the warm home and breakfast, perhaps we can change the way of life, the RV to take you to travel to poetry and and far away.

“Home is in the car, life is on the road”, the RV the caravan is imaginatively compared to a “home in a car”. Comfortable bedroom, spacious living room, clean bathroom and neat kitchen, everything is just like at home, with all the amenities. So the question is, how can a home lack water when almost every amenity needs water? The RV water system is like the circulatory system of the human body, which is particularly important for RVs. It is not only convenient and quick to install, but also easy to maintain in the later period.

A complete RV water system, including water supply and sewage treatment system, the three main components are a clean water tank, a black water tank, and a gray water tank.
Clean water tank: The clean water tank is a water tank used to store clean drinking water and domestic water, and is also the source of water for RVs.
Black water tank: The black water tank is a container used to store the waste water discharged from the toilet. Special degradants and deodorants are usually added inside, which can better degrade solids and remove odors, providing a beautiful environment for the RV.
Grey water tank: A grey water tank is a tank used to collect and treat domestic wastewater, such as common drainage from vegetable sinks, washbasins and bathrooms.

So how to pressurize the water supply of the clean tank in the car? The built-in clean water tank usually adopts a clean water inlet with a lock, and the water pipe outside the car is used to fill the clean water tank. Water is usually added at the faucets of high-speed service areas, campsites, and farms. Pressurized pumps are not needed at this time. When the external water supply stops, this time you need to choose a TOPSFLO 12V/24V C02 automatic pressurized water pump, so that the RV water is not affected.

Install this TL-C02 booster water pump in the recreational vehicle, after turning on the water pump switch, it will pressurize the entire water supply pipe in the recreational vehicle. TOPSFLO TL-C02 BLDC booster pump adopts high-efficiency motor and rotor design, with small water loss, large flow head, high energy efficiency and remarkable boosting effect. At the same time, it adopts a silent design, and the noise is as low as 40dB(A), which is much lower than that of ordinary water pumps in the market. The TL-C02 series has obtained the high-standard drinking water industry safety WRAS certification in the United Kingdom, and at the same time passed the REACH, CE, FDA, ROHS certification, and takes care of the healthy water for you and your family.
Poetry and distance are ideals, and home is reality. RV has changed people’s definition of home. Home not only waits for you to go home, but also accompanies you to see the beauty of the world. TOPSFLO is always by your side, escorting your healthy life.

Application of Solar DC Pump TD5 in Hot Water Circulation System

TOPSFLO TD5 solar hot water circulating pump has been widely used in New Solar Whole House Water Heating System，and has been recognized and praised by customers.

The new solar hot water circulation system works by installing solar collectors on the roof, and the buckets are installed below the roof or on the ground. We need a circulation pump to continuously circulate cold water to the collectors. The collector circulates the hot water to form a closed-loop system circulation to realize the exchange of cold and hot water.

At present, water pumps used in New Solar Whole House Water Heating System on the market are roughly divided into two types: alternating current circulation pump and direct current solar hot water pump.

Compared with the traditional separated AC circulating pump, the DC solar hot water pump has the following advantages:

Energy saving, environmental protection and safer: using solar panels to supply power directly, 6V low voltage start, 2W low power start, and water pump can start and work normally when the sunlight is weak in the morning. no need to use household AC power supply, very energy saving (if install DC solar energy system in the developed countries in Europe and America, the government will give certain subsidies accordingly) . The water pump itself is DC low voltage, which is very safe to use, avoiding the risk of AC pumps.

1. Long service life: solar system pump adopts the most advanced magnetic drive method, and the lifetime is more than 30,000 hours. Compared with the lifetime of AC pump of about 6,000 hours, it is greatly increased, and the average cost-effectiveness of the customer’s use is greatly improved.
2. Low noise: solar DC circulating pump is an isolated centrifugal pump, the friction between the bearing and shaft is very small，so the working noise of the pump is lower than that of AC pump, and quieter.
3. Small size: DC pump is about 1/3 the size of the traditional AC pump, which is more convenient to install and use;
4. MPPT function：Every three seconds, the processor modifies the operating point on the PV panel’s voltage-current curve to find the point of optimal performance. No separate performance equipment is required, TD5 solar pump automatically finds the optimum operating point for maximum performance under any given light and temperature conditions. Compared with general pumps on the market, the efficiency can be improved by 30%-50%.

Advantages over solar pumps from EL SID Solar DC Pump and Laing D5 DC Solar Pump
Many of our clients also reflected application problems by using SID and Laing-D5 pumps, such as tempreature, MPPT max efficiency and so on. But they are very satisfied with ours till now since transition. Our TD5 solar circulation pumps are developed by studying SID and Laing-D5 pumps first,Then optimize their weakness.
For example, there exists tempreature issue due to spherical motor for Laing D5 pumps, and SID pumps do not have MPPT functions. Generally, our solar pumps have comprehend all advantages and optimize the advantages for supporting solar system at its max performance, and have been tested and applied in the market for a long time with nice feedback. I believe topsflo will be a great choice for you.

As the only professional solar water pump supplier in China, TOPSFLO will continue to improve technology, innovate and make breakthroughs, turn customer recognition and support into continuous forward momentum, and strive to become a leader in the global micro pump industry.

EV Charging Stations pump

Technical difficulties: serious heat generation caused by high power
Overcharging can bring users a more convenient experience. Who doesn’t want to fully charge the vehicle in 5 minutes, but the problems of overcharging have also stumped many car companies.
With simple physical knowledge, overcharging is actually increasing the charging power. According to the power formula: P=U×I, that is, increasing the voltage or current can increase the power.
Of course, it seems simple in theory, but not so easy in practice. If the current is increased, due to the limitation of the internal space of the charging pile, heat will rapidly accumulate in the charging pile, so that the temperature of the pile body will continue to rise, affecting the stable use of internal components. In order to ensure the stable operation of the supercharged pile and improve the safety and reliability of the equipment, the heat dissipation problem must be solved first.

Solution: Increase Cable VS Liquid Cooling
There are mainly two solutions for the pain point of heat dissipation: 1. Increasing the cable area to increase the current carrying capacity; 2. Using better cooling technology to enable the module or cable to cool down faster.

At present, some manufacturers in the market have adopted the first solution, and the result is: heavy gun head, thick cable, and poor user experience. When charging, the car owner needs to unplug the gun head weighing 3~4 kg, and also drag the long and thick charging cable on the ground, which is very unfriendly to female car owners.

The second solution is adopting better cooling technology.

T company is the first car company in the world to adopt liquid-cooled charging. In March 2019,  V3 supercharged pile debuted in the world. The liquid-cooled charging cable used is about 44% smaller than the diameter of the V2 supercharged pile , only 23.87mm.

Subsequently, more and more companies chose liquid cooling technology.

In August 2021, GAC Aion A480 supercharged pile was released. The entire pile body adopts liquid cooling technology and lightweight liquid-cooled cables. In April 2022, TELD liquid-cooled super-charging pile was launched, with maximum charging power of 600kW and liquid-cooled control system. In August, Xiaopeng S4 ultra-fast charging pile was launched, the maximum power of a single pile is 480kW, the maximum current is 670A, and it also adopts liquid cooling technology.

Compared with the traditional air-cooled charging pile, the liquid-cooled charging pile not only has a super fast charging speed, but also has the advantages of low noise, low heat generation and high safety. At the same time, the charging equipment is light in weight, bringing a more comfortable charging experience.

At the beginning of September, thousands of liquid cooling water pumps supplied by Topsflo to American T companies were shipped out as usual. According to the representative of Topsflo, T company is a world-renowned manufacturer of DC fast charging piles for electric vehicles, and Topsflo provides liquid-cooled circulating water pumps for their 350KW super charging piles, mass production starting from February 2021. At present, the 350KW super charging piles from T company have been sold to 41 countries, and tens of thousands of super charging piles using Topsflo pumps are standing all over the world.

In fact, the founder of Topsflo, Richard Wang, has awared of the huge potential of the new energy vehicle charging pile market many years ago. Mr. Wang entered the micro pump industry since 2005, and he is one of the experts who engaged in the research and development of brushless DC pumps in China at the earliest time. Mr. Wang is also a researcher who is fully proficient in micro pumps in Europe, America and Japan. Perennial attention to the European and American markets made him aware the situation early: The US electric vehicle charging pile market, which started at the end of the 20th century, has developed steadily and received strong support from all aspects of the government. In China, although the electric vehicle industry started late, development is inevitable. Seizing the opportunity is the way to develop. Therefore, Topsflo is the first to enter the market, and it has laid out the charging pile cooling application field with an advanced vision.

In 2015, Topsflo became the pump supplier of TESLA, and has provided 250,000 liquid-cooled circulating pumps for them. On the busy streets of Wall Street, Topsflo pumps are behind the rows of charging piles. Up to now, Topsflo has successfully provided high-efficiency liquid cooling solutions for more than 20 well-known enterprises in the charging pile industry.

How to choose a liquid-cooled charging pile water pump? These features are important!

Charging piles belong to civil infrastructure, most of which are deployed in outdoor scenarios, and need to withstand the test of high dust, flying flocculent, heavy salt spray, and highly corrosive substances that are not conducive to equipment operation. The problem is that the equipment has a high failure rate. Unstable operation and other phenomena cannot be safely produced, and operators cannot get a good return on investment, which puts forward higher requirements for the safety and reliability of charging piles.
Therefore, liquid-cooled charging piles came into being.

Liquid cooling technology, the current mainstream of the charging pile market

The first batch of liquid-cooled charging piles are the V3 super charging piles launched by Tesla in 2020, which can achieve a maximum range of 250km after charging for 15 minutes, using liquid-cooling technology. The charging pile scheme announced by Tecom in early April this year also uses liquid cooling technology, which can increase the cruising range of the vehicle by 300km after 5 minutes of charging.

2. Strong environmental adaptability: no direct heat exchange with outside air is required, and it is protected from damage to power and electronic devices caused by external dust, salt spray, humidity and other unfavorable environments, especially in application scenarios where the above factors are relatively harsh.
3. High safety and convenient maintenance: The liquid cooling circuit is isolated from the electrical circuit, and the electrical and heat exchange compartments are designed separately. The electrical compartment is protected from adverse environmental erosion, and the accumulated dust in the heat exchange compartment can be directly washed.
4. High reliability and long service life: ensure the working environment temperature of electronic components and prolong the service life of modules and systems.

Liquid-cooled coolant pumps make charging piles more competitive
The principle of the liquid-cooled charging pile is not difficult to understand, that is, a special circulation channel is set between the cable and the charging gun, and the cooling liquid that can play a role in heat dissipation is added to the channel, and then the liquid circulation is pushed by the power pump to take away the heat. So, how to choose a liquid-cooled charging pile water pump?

We look forward to working with more charging pile enterprises to contribute to the innovation and development of the industry!

In the field of liquid cooling of charging pile cables for many years, TOPSFLO pump industry calmly copes with the era of ultra-fast charging

Many people have to consider the issue of charging when buying new energy vehicles. Compared with the slow charging of “small water and long flow”, convenient and efficient super charging piles are more in line with the needs of car owners, which has also become the focus of competition between car companies and charging pile companies. Electric vehicles are moving towards the era of super fast charging, which has also driven the use of liquid-cooled charging cables.

The layout of ultra-fast charging is the general trend
Once, OPPO’s slogan “charge for 5 minutes, talk for two hours” opened up the era of super fast charging of mobile phones. Now, this phrase is used in the field of new energy vehicles.
On August 15, Xiaopeng Motors released the S4 ultra-fast charging technology, which can charge for 5 minutes and have a range of 200 kilometers. At the same time, it was announced that 1,000 self-operated charging stations will be launched, which is also the first station in the country equipped with the latest generation of ultra-fast charging pile S4. Xiaopeng plans to build another 2,000 ultra-fast charging stations by 2025.
On August 30, Sinopec’s first community super charging station in China, Lotus Super Charging Station, was completed and put into use in Longyan City, Fujian Province. It can charge 24 vehicles, integrating refueling, charging, photovoltaics, and rest. An ordinary family car with a range of about 400 kilometers can be filled in minutes.
As the market’s requirements for the charging capacity of electric vehicles continue to increase, high-power fast charging and super fast charging have become an inevitable option for car companies to improve their advantages, which also means that the utilization rate of liquid-cooled charging cables will be greatly improved.

Liquid-cooled cables solve the problem of charging thermal damage
For ordinary car charging cables, the increase of charging current and voltage is bound to increase the wire diameter and insulation thickness of the cable to ensure the smooth transmission of high-power current, but this also makes the cable thick and hard, and the charging gun is cumbersome and difficult. In addition, the high-power current transmission will inevitably dissipate more heat. During the charging period, the charging gun contacts the car at a high temperature, which will easily increase the risk of spontaneous combustion of the car.
The use of liquid-cooled high-power charging cables can alleviate the above problems. The liquid cooling cable is a special cable used for high-current heating equipment. A special circulation channel is set between the cable and the charging gun. The heat dissipation effect is more suitable for high-power charging of electric vehicles, which can reduce the thermal damage caused by high-power charging to the charging gun, charging cable, and charging pile.
As the first car company in the world to adopt liquid-cooled charging, Tesla has been developing a charging station with a new liquid-cooling system in 2015. In March 2019, Tesla V3 supercharger appeared in the world, using a liquid-cooled charging cable. The diameter of the charging cable is about 44% smaller than that of the V2 supercharger, which is only 23.87mm. The maximum peak power of the supercharger can reach 250kW.
With the continuous adjustment and upgrading of the electric vehicle industry, the hardware requirements of high-power charging and fast charging will continue to drive the electric vehicle charging connection device. Products must master cooling technology, and liquid-cooled circulating water pumps have also become the focus of liquid-cooled charging cables and even charging pile manufacturers. one of the focal points.

TOPSFLO provides mature solutions for liquid cooling of supercharged pile cables

Small Water Pump TL-B04

Liquid Cooling is the Future Trend of EV Fast Charger Market

Affected by the international situation, oil and energy prices raised in 2022. At the same time, China has pledged to peak carbon dioxide emissions in 2030 and strive to achieve carbon neutrality in 2060. Driven by comprehensive factors, new energy vehicles have become the mainstream of future vehicles. In view of the development of the general environment, the infrastructure supporting facilities for new energy vehicles – the charging pile market has also become the focus of major enterprises.

The latest data from China Economic Net on August 3, 2022: The National Energy Administration held an online press conference for the third quarter of 2022. From January to June, 1.3 million charging stations were added nationwide, 3.8 times that of the same period last year, according to the report. At present, the types of charging products on the market are mainly divided into two categories: liquid-cooled charging products and air-cooled charging products. The main difference lies in the different heat dissipation methods used by the products.

Today, editor will explore the difference and advantages and disadvantages of air cooling and liquid cooling of charging piles, so that you can avoid detours in the design of “charging pile cooling scheme”.

Heat dissipation is a difficult problem that must be solved in the construction of charging pile
Compared with other power sources, the system heat dissipation of charging pile is much larger, and the system thermal design requirements are extremely strict.
The power range of DC charging pile is 30KW, 60KW and 120KW, 350KW … 600kW etc. . The efficiency is generally about 95%, so 5% of it will be converted into heat loss, and the heat loss will be 1.5kW, 3KW and 6KW. For outdoor equipment, the heat must be discharged from the equipment, otherwise it will accelerate the aging of the equipment. At the same time, it is necessary to do a good job of waterproof and dustproof treatment to prevent the occurrence of short circuit and signal disorder of electronic equipment.
In order to intuitively let you know the calorific value generated by charging pile under normal operation, we compared the charging pile with 60KW power with the communication power supply cabinet: At present, the nominal efficiency of the mainstream module in the industry is 95%. Taking the 60KW system as an example, the heat dissipation of the module alone reaches 60*0.05*1000=3000W, which means that the heat generated by the charging pile in the charging process is 3 times of the heat dissipated by the communication outdoor cabinet under the same volume condition. It can be seen that the heat generated by the charging pile in the charging process is large, and if it is not released in time, it will cause a great safety accident. Therefore, the heat dissipation problem is one of the problems that must be solved in the promotion and construction of the charging pile system!

Air cooling and liquid cooling are the mainstream cooling methods in the market
At present, the mainstream heat dissipation methods of charging piles mainly include direct ventilation forced cooling, liquid cooling and heat dissipation by heat pipes (the whole machine is closed and air-cooled modules are used). Direct ventilation is the mainstream cooling method for domestic charging modules, but it is transforming to liquid cooling. Liquid cooling has been widely used in North American and European markets and has become the mainstream of the industry.

According to the different designs of air cooling and water cooling, the editor made a simple comparison table of advantages and disadvantages, which can compare the two types more intuitively.

Advantages and disadvantages of cooling methods.
From the picture, we know that the air-cooled heat dissipation is mainly forced to dissipate heat through the external air, which causes outdoor dust to easily enter the cabinet and contaminate the precision components. If the heat dissipation of the heating body is not strong, the heat is easy to accumulate in the heating body, and even if the external heat dissipation is strong, the effect will be limited. At present, some companies also use closed cold and heat isolation air duct technology to avoid the above shortcomings, and have been applied to actual charging piles.

Breaking through limitations, the overall cost of liquid cooling is lower
For charging operators, charging piles are the production tools they use to make money. In addition to operating income, product quality, service life, and after-sales maintenance costs are all important factors that affect the final revenue. The maximum economic value is excavated during the life cycle, so the one-time purchase cost is no longer the primary concern of operators, and the service life and later operation and maintenance costs have become the key aspects of comprehensive consideration for operators.
Compared with the limitations of air-cooled charging products, liquid-cooled charging products have gradually entered the stage and occupy an important position in the charging market.
So what are the characteristics of liquid cooling of charging modules that have been widely used in North American and European markets? From the perspective of the entire life cycle of the equipment, the overall cost of liquid cooling modules is undoubtedly lower. Compared with air-cooled heat dissipation, liquid-cooled heat dissipation has stronger heat dissipation capacity, higher efficiency, lower power consumption and stronger output voltage.

Heat dissipation capacity: The cooling of the module device is 10~20℃ lower than that of the forced air cooling module.
Efficiency: the highest efficiency > 96%, the overall efficiency > 93%. For example, a 30kW module is used for 300 days a year, and the utilization rate is 20% per day. Each increase of one point can save 450kWh of electricity per year and reduce operating costs (OPEX).
Power consumption: Standby power consumption is less than 10W.
Output voltage: The output voltage of the module can reach 1000V, which is more in line with the construction and layout trend of super charging.
Take the Tesla Supercharger V3’s liquid-cooled cable as an example, and its vehicle coolant pump is located at the base of the white SC gear. The appearance is basically the same as the previous generation, the only difference is that the charging cable looks thinner and achieves higher charging efficiency. The specific data are: power conversion efficiency (V3 is 96%, V2 is 92%) and more low cost. The total AC input is 438kVA, 526A, which can support a maximum output power of 250kW. Any additional power can be shared between cabinets. The site master controller is 4G LTE, which is used to detect the power consumption and billing of the car.

TOPSFLO’s high-quality liquid cooling water pump is favored by many giants
At present, liquid cooling has become the mainstream of the European and American charging markets, and domestic charging modules have also been concentrating on research and development to transform to liquid cooling. Liquid-cooled heat dissipation charging piles are bound to become the most reliable choice for new energy electric vehicle charging solutions.
In order to achieve the best cooling effect of the charging pile, the selection of high-quality liquid-cooled water pumps is also very important. TOPSFLO liquid-cooled EV chargingcoolant pump has a long life of 30,000 hours, maintenance-free, zero maintenance, and supports the working conditions of storage temperature -40~80 degrees, operating temperature -30~50 degrees, and medium temperature -30~90 degrees, so as to provide new Energy electric vehicles provide stable and reliable charging solutions. At the same time, it also has intelligent control function, which can realize 5V/PWM speed regulation, FG speed signal feedback and other functions, and can customize six protection functions of idling, water shortage, locked rotor, overcurrent, reverse connection, and overvoltage.
With stable performance and rich product selection, TOPSFLO dc supercharging cooling pump has attracted widespread attention in the charging pile industry, and has successfully reached strategic partnerships with many giant companies, such as the successful matching of TOPSFLO TL-B10 four-wire intelligent control water pump. In the projects of famous German companies and domestic listed companies, TOPSFLO TA60 intelligent control model has been used in the products of famous Australian companies and domestic famous companies. There are also a variety of cooling water pumps favored by many charging pile manufacturers. Welcome more charging pile customers to negotiate, and TOPSFLO engineers will recommend the most suitable cooling water pump solution for you.

Liquid-cooled supercharging technology attracts attention | TOPSFLO cooling water pump enables “cold and fast” charging piles

With the development of new energy vehicle battery technology, battery life has been significantly improved, but the problem of slow charging still plagues the entire industry and has become an important factor hindering the rapid increase in the penetration rate of new energy vehicles. More efficient and safer liquid-cooled supercharging technology, as a new trend in the industry’s technological evolution, has become the focus of the industry’s efforts. TOPSFLO pump industry has been supplying liquid-cooled cooling water pumps to Terras since 2015, which really helps super charging piles to achieve “cold and fast”.

The principle of liquid cooling technology is not complicated. To put it simply, a special circulation channel is set between the cable and the charging gun. The cooling liquid for heat dissipation is added to the channel, and the liquid is circulated through the power pump to take out the heat. Compared with the traditional air-cooled charging pile, the liquid-cooled charging pile not only has a super fast charging speed, but also has the advantages of low noise and no disturbance to the public.

But on the other hand, the technical difficulty of liquid cooling is still relatively high. When the current and voltage are very large, the system is very easy to heat up, and the electrical loss will be relatively high. The problem of heat dissipation of charging equipment directly determines the service life and stability of the equipment. Therefore, it is also extremely important to choose a high-quality water pump supplier.
As a super-filled pile manufacturer, how to choose a high-quality liquid-cooled circulating pump supplier? The TOPSFLO pump engineer who has been deeply involved in the industry for more than ten years will take you to understand the following points:
First of all, choosing a charging pile liquid-cooled Supercharging pump supplier with independent research and development and its own factory is more guaranteed in terms of product quality, delivery time, and customized development.

What should we pay attention to when choosing a CPU radiator cooling water pump?

Application of TOPSFLO Pump Products in Global Anti-epidemic Medical Devices

Internationally, the main epidemic strains of the COVID-19 are still evolving, and the COVID-19 in many countries is showing a rebound trend. The WHO stressed that the COVID-19 pandemic remains a public health emergency of international concern. Thousands of people around the world are still infected everyday. Therefore, the demand for important medical equipment in hospitals is also increasing, such as ventilators, defibrillators, Atomizers, patient monitors, ECMO, CT, etc.
Pump is an indispensable component in the application of medical devices. This article will show you those TOPSFLO medical pumps that work in anti-epidemic medical devices.

Ventilator

Ventilator is the key equipment to prevent and treat respiratory failure, save and prolong patient’s life. Pneumonia caused by the COVID-19 is most prone to hypoxemia, which is what we often call low oxygen saturation. The most direct way to treat this symptom is to inhale oxygen, and then use mechanical ventilation, that is, a ventilator.
For patients with pneumonia caused by the COVID-19, the ventilator is their “life-saving machine”. If you are unfortunately infected with the COVID-19 and have difficulty breathing, the most important thing is to get timely medical treatment and use appropriate assisted breathing. The ventilator replaces the person’s own breathing process, which can help the patient to resist the infection and eventually recover.
Topsflo double-head diaphragm air pump is currently operating in the ventilator ventilation system used in the fight against the epidemic. It adopts food-grade safe raw materials, has a highly optimized heat dissipation structure and a patented diaphragm structure, and has good heat dissipation and wear-resistance performance, which can effectively ensure the ventilator’s stable operation and provide clean compressed air for patients with breathing difficulties.

Atomizer

Atomization inhalation therapy is an important and effective treatment method in respiratory system diseases. It is mainly used to treat various upper and lower respiratory system diseases. Atomizer inhaler is used to atomize the liquid medicine into tiny particles, and the medicine is inhaled through breathing into the respiratory tract and lung deposition, so as to achieve the purpose of painless, rapid and effective treatment. For patients with new coronary pneumonia, atomization expectorant and interferon atomization inhalation are common treatments in the recovery process.
Because the liquid medicine needs to be pressurized by a high-pressure pump and then sprayed into the atomizer to be atomized, the pump is the key component of the atomizer equipment. The high-end series of  Topsflo diaphragm air pumps perfectly match the application requirements of the atomizer. Its brushed motor and brushless motor all adopt the self-designed medical EMC motor scheme to ensure that the entire atomizer can pass the IEC 60601 standard test, and the products meet the requirements CE, ROHS, REACH standards and can better meet the needs of customers in the medical industry.

Gene Sequencer

The gene sequencer can be used for gene and virus screening. Its application in the diagnosis of infectious diseases is mainly reflected in the following: using sequencing technology to identify the gene sequence of the pathogen corresponding to an infectious disease Efficacy and safety of medication. At the same time, genetic sequencing can be used to discover new pathogens and better prevent them. During the epidemic, gene sequencers can make more accurate and faster diagnosis of new crown patients and co-infected people.
The gene sequencer needs to rely on the water pump to cool the chip platform. As the core component of the device, the water pump is very important to ensure its stability. At present, TOPSFLO DC brushless pumps have been successfully used in gene sequencers developed by well-known domestic medical equipment manufacturers, and sent to major hospitals and testing institutions to assist in anti-epidemic work and virus screening. During the tense period of the epidemic, TOPSFLO Medical Device Pump well fulfill every mission in the gene sequencer, improved the efficiency of gene and virus screening, and helped fight the epidemic with stable and reliable quality.

Medical equipment can save lives . In order to meet the needs of medical equipment manufacturers during the epidemic, TOPSFLO focuses on tailor-made options for specific needs in many aspects to ensure the maximum effect of the product during use, like safety, chemical resistance, temperature resistance, size, vibration, control, motor, voltage, noise. In addition to the above medical devices, Topsflo products have also been successfully used in other medical products such as nasal aspirator, medical rehabilitation massage, and heat and cold physiotherapy equipment.
Topsflo is proud to be able to provide the best support in the fight against the epidemic! We will continue to make breakthroughs and strive to provide higher quality products and solutions for more industries!

A comprehensive guide to the installation and benefits of the TOPSFLO car Engine preheater pump

As a pioneering brand in Automotive water pump, TOPSFLO has led the way in providing innovative water pump solutions across various sectors, including solar energy, water heating mattresses, battery cooling, hot drink machines, and more since its founding in 2005. Our products have consistently received high praise in the market. In the automotive preheater sector, the car preheater water pump developed by TOPSFLO has been widely recognized by high-end preheater manufacturers, both domestically and internationally. TOPSFLO has also established long-term partnerships with leading domestic suppliers of military-grade preheaters.

So, which models are compatible with the TOPSFLO Vehicle heating water pump? And why should you choose TOPSFLO pumps? This article aims to clarify these points.

Function of the Car Preheater Water Pump

Car preheaters eliminate the need for warming up the garage in winter and solve the common problem of hard-to-start vehicles after they’ve been parked in freezing temperatures. Even in extreme cold of -30°C, you can start your car and drive away without issues. The preheater works by warming the engine, defrosting the windows, and heating the interior of the car. For fuel vehicles, the preheater gets its heat from burning gasoline, and it can work after the engine is off or during driving as an auxiliary heater.

So, what role does the car preheater water pump play in this system?
The preheater water pump circulates the coolant from the engine, heats it in the preheater, and then returns it to the engine. This process helps warm the engine and ensures smooth starting in low temperatures.

Compatible Models for TOPSFLO Automotive water pump

TA50 series: Compatible with 5KW liquid heaters	TA60 series: Compatible with 10KW liquid heaters

Installation Guide for TOPSFLO Car Preheater Water Pump

To install the pump, position it between the engine’s outlet and the heat exchanger of the interior heater. The water flow should follow this sequence:

• Water outlet of the engine → Inlet of the preheater water pump
• Outlet of the preheater water pump → Cooling water inlet of the preheater (marked “IN”)
• Cooling water outlet of the preheater (marked “OUT”) → Interior heater heat exchanger.

Ensure that the Cold start water pump is installed lower than the preheater.

• Secure the water pipe joints with the provided pipe clamps.
• Do not extend the wiring harness. The specified distance between the pump and the engine is critical to avoid malfunctioning.
• Pay attention to the antifreeze during installation. Supplement the system with antifreeze of the same specification, and ensure the engine is run for a while to reach the required coolant level.

Special Installation Note:

If air needs to be purged from the pump each time it starts, install the pump as shown in the figure below to assist with air removal and reduce noise during startup. If no purging is required, the pump can be installed in any position.

Key Advantages of TOPSFLO Car Preheater Water Pump

Meet Diverse Needs and Improve End Customers Experience ——TOPSFLO Pumps, Pioneer of Intelligent Speed Regulation Technology

With the progress of the times and the development of science and technology, people’s demand for intelligent products is getting higher and higher. This demand also extends to the pump industry. For example, professional fields such as medical treatment, automobile, laboratory, water treatment, etc. have high requirements on the volume, noise and power consumption of water pumps, and at the same time, there is an increasingly strong market demand for the customized speed regulation function of water pumps.

The customized speed regulation function of  TOPSFLO DC brushless centrifugal pumps (hereinafter referred to as “centrifugal pumps”) has been widely used in fields with high speed control requirements. This is thanks to TOPSFLO’s customized speed-regulating water pump solution that enables infinitely smooth speed regulation, and realizes closed-loop control through speed feedback. Thus, it can easily adapt to different working conditions in different industries, thereby improving the efficiency of the process.

Benefits of Customized Speed Control Function for Centrifugal Pumps
At present, there are many types of centrifugal pump products on the market, many of them do not have speed regulation function, nor do they support customized speed regulation, because the speed regulation function of the pump will make the electronic solution design of the circuit board more complicated, and the requirements for stability and reliability are higher. The cost will also be higher.

TOPSFLO Pumps has experienced electronic engineers. When designing electronic solutions, they will consider the needs of customers in different industries. Therefore, the circuit board has excellent performance in terms of stability and reliability, and has been unanimously recognized by many customers at home and abroad. The following are the three major advantages of TOPSFLO centrifugal pump customized speed regulation function:

1.Can adapt to the needs of different stages of actual working conditions
The centrifugal pump which customized with speed regulation function, can adjust the speed based on the actual application needs, and control and adjust the water flow, water head, and pressure of the pump to meet the actual working conditions of customers in different industries.
2. Low power consumption, high efficiency and long lifetime
The start-up function of the speed-regulated water pump is very prominent, so that the start-up current changes from zero, the maximum value does not exceed the rated current, and it is very stable without impact, and the control power is very small under the same process. Moreover, the efficient speed regulation method can control the output torque more accurately, reduce the motor loss and the heating of the electronic components, prolong the service life of the pump, and save the maintenance cost of the equipment.
3. Simple operation and convenient control
Generally, a centrifugal pump with speed regulation function has 3 wires, namely red wire, black wire and blue wire. Usually, the red wire is the positive pole of the power supply, the black wire is the negative pole of the power supply, and the blue line represents the speed adjustment line. The wiring method of the speed regulation function of the centrifugal pump is very simple, the control is convenient, and troubles caused by improper operation can be reduced.

The excellent performance of the customized speed regulation function of TOPSFLO centrifugal pumps is due to the company’s excellent R&D and design strength. Started in 2005, TOPSFLO has a group of professional structural engineers, motor engineers and electronic engineers, who can not only customize the speed regulation function, but also customize the size, structure, materials and other aspects of the pump. Over the years, TOPSFLO has cooperated with many internationally renowned companies such as Tesla, Whirlpool, Bosch, KTM, KOHLER and provided OEM supporting services, which has won unanimous praise from customers.

Topsflo Micro Brushless Water Pump Repass the British WRAS certification

WRAS (Water Regulations Advisory Scheme) certification refers to the Water Regulations Advisory Scheme, which is a certification for drinking water safety in the UK. It is a standard enforced by British Water and is a mark of compliance that covers all fittings and materials that come into contact with water by public water systems. Once approved, the WRAS is valid for up to five years, after which the product needs to be resubmitted for evaluation, which shows the strictness of passing requirements. The certification includes various safety tests for the test material:
A. The smell and taste of water in contact with the material will not change
B. The appearance of the material in contact with water does not change
C. Does not cause the growth of aquatic microorganisms
D. No precipitation of toxic metals
E. Will not contain or release substances that affect public health

Topsflo micro pump industry has always been positioned as the mid-to-high-end market in Europe and the United States, making continuous efforts with international high standards, and always insisting on improving the relevant quality certification of products, meeting customer application requirement and gaining the trust and recognition of customers in different industries. The product was first WRAS certified in 2017, and five years later Topsflo pumps have again successfully passed this water fitting compliance certification in a UK laboratory.

In the UK, although it is not illegal for water fittings without the WRAS mark, from the perspective of the health of drinking water for residents, it is necessary to prove that they can pass the relevant regulations to ensure the safety of the water supply system. Therefore, products with their own WRAS certification are generally selected. The water pump is a key accessory for drinking equipment, and compliance with this certification not only demonstrates its compliance, but is also the easiest and most reliable way for accessory buyers to avoid selecting low-quality or defective products.

Although WRAS certification has become a common practice as a necessary license for the British market, but there was no laboratory in China that could do this test in the early years, and the materials had to be sent to the British laboratory for testing, which increased the complexity of the entire testing process. However, due to Topsflo’s emphasis on the UK and even the entire European market, and the strict requirements for its own product high quality standards and excellence, it still overcomes difficulties and sends the product to the UK laboratory for BS6920 standard compliance testing and finally obtains certification. Which fully reflects the determination of Topsflo people to make high-end miniature brushless DC centrifugal pumps.

How strict is the WRAS certification test? It can be said that a little component can lead to the failure of the whole result. Here is a small story of Topsflo’s first certification process. At that time, the British laboratory reported that the graphite bearing of the pump failed to pass the test, but the actual raw materials and ingredients of the part did not contain this material, which made the technical team puzzled. After some investigation, it was found that the trace metal substance was contaminated with a metal processing tool of the supplier, and immediately negotiated with the supplier to readjust and improve the production process. After the second sample delivery, all the wading parts of the related dc brushless centrifugal pump TL-B10 series products successfully passed the test.

Today, in the in-depth cooperation with high-end customers, Topsflo Pumps has accumulated more experience in pump design and material selection. The full range of TL miniature brushless DC water pumps has undoubtedly passed the WRAS compliance certification again, representing the improvement of the overall quality of Topsflo micro pumps over the years. Which not only enhances the confidence of British and European customers in the long-term use of pumps, but also helps them develop more products that meet market demand, occupy a larger market share, and truly become a solid backing behind the stable development of customers.

Strictly select global raw material suppliers, Topsflo micro pumps use international well-known brand raw materials, directly imported from the original factory, without any return material in the production process, high consistency in batch and long-term use, and good sealing during operation, which can meet the high requirements of customers in the high-end home appliance industry. Quality requirements, widely used in drinking water machines, hot drink machines, water dispensers, purifiers and other drinking industries, well received by customers, and look forward to sincere cooperation with more customers for a win-win future.

The application of micro water pump in different types of humidifier

A humidifier is a household appliance that increases the humidity in a room. The development of the humidifier industry in China has a history of nearly 20 years. After years of popularization of air quality concepts, product research & development, and market cultivation, the functions and role of humidifiers, a relatively unfamiliar small household appliance, have gradually been accepted. As consumers’ demand for humidifiers begins to shift from basic humidification to diversified changes, such as beauty, non-radiation, zero pollution, and low noise etc., the product structure of humidifiers is constantly being optimized, and technological innovation has also been accelerating the transformation and upgrading of the industry.

From the original “atomizing humidifier” to “waterless mist humidifier”, and to the more popular “air purifying humidifier” that appeared during the COVID-19 epidemic, pumps are required for all of them. Today let’s learn about the application of micro water pumps in these three different types of humidifiers.

Atomizing Humidifier
Atomizing humidifiers are also called evaporative humidifiers, which can be divided into direct evaporation type and thermal evaporation type.
Direct evaporative humidifiers are often referred to as pure humidifiers. The pure humidification technology is a new technology just adopted in the humidification field. The pure humidifier removes the calcium and magnesium ions in the water through the molecular sieve evaporation technology, and completely solves the “white powder” problem. Thermal evaporative humidifiers are also called electric humidifiers. Its working principle is to heat the water to 100 degrees in the heating body to generate water vapor, which is sent out by a fan. Electric humidifiers are generally used in conjunction with central air conditioners, instead of using alone.

Structurally, the atomizing humidifier generally includes: water tank, water suction pipe, base, micro water pump, controller, atomizer, etc., and the micro dc water pump is located under the interior of the water tank, and one end of the suction pipe and the return pipe is connected with the micro water pump. The micro water pump transports the water in the water tank to the atomizer. After the atomizer atomizes the water, it turns into a fine water mist through the atomizing nozzle, and sprays it into the air to achieve the effect of humidification.

Waterless Mist Humidifier
The waterless mist humidifier is a cold evaporative humidifier. Its working principle is to inhale the dry air in the room through the built-in fan of the humidifier, and blow the moist evaporative filter element or filter screen through the circulating air, and blow the moist air carrying water molecules into the indoor, to achieve the purpose of humidifying indoor air. No spray can be seen during use, but it brings a smooth and silent effect.

The humidifier is equipped with a water pump for water circulation. Its working principle is to circulate the water in the water tank to the filter screen, and then transport water molecules to the room through the fan to achieve the effect of humidification. The water mist cannot be seen by the naked eye, but the humidity will increase. At the same time, the humidifier is equipped with a built-in sterilization device to ensure the safety and health of water quality and moisture, and it is easy and safe to use.

Air Purifying Humidifier
The humidification principle of the air purifier is to continuously pass the indoor air through the air purifier through its own or external fan when purifying the indoor air. And the purification technology of the ion group, gradually remove the particulate matter and toxic gas in the air, and finally send the clean air through the air outlet. The air purifier with additional humidification function belongs to the “air purifying humidifier”. The water pump mainly acts in the water circulation of the water tank to achieve the effect of humidification.

So, what is the main role of the humidification function of the air purifier? Firstly, the healthy humidification and natural vaporization way of humidify, releasing pure water molecules that are closer to nature, which is more beneficial to human health and has no secondary pollution; Secondly, doubling the purification and humidification function can increase the lifespan of the ion group, improve the ability to remove solid pollution such as dust and dust mites in the air, and improve the purification ability to remove formaldehyde, odor, second-hand smoke, etc. It can not only humidify, but also purify, kill two birds with one stone, why not do it?

TOPSFLO silent water pump empowers the development of the humidifier industry
With the increasing progress of society, the destruction of the environment by social development has unknowingly played a degrading role, and environmental problems are constantly being induced. Air pollution, dryness, turbidity, and diseases caused by indoor air environment are also increasing. Coupled with the continuation of the COVID-19 epidemic, air purifying humidifiers will become an “indispensable member” of every family in the future. Choosing a silent water pump that can accompany users to sleep has become a “top priority” for all humidifier manufacturers.

TOPSFLO 12V DC water pump adopts the industry’s unique patented silent design and magnetic silent rotor imported from Japan, with low rotor unbalance, effectively reducing friction, noise as low as 25dB, and ensuring long-term silent operation; At the same time, using high-precision molds from Japanese-funded mold factory for injection molding, long-term production precision control is stable, and noise batch consistency is high. The product is stable and reliable for a long time, has a long service life, is maintenance-free, and has no problems such as bad feedback on noise etc.

Twelve years together, TOPSFLO has grown together with global famous automotive air-conditioning customers

From 2010 to 2022, just like Ma Liang’s magic brush, Changsha has taken on an entirely new look, from “blueprint on paper” to fame — replacing flat houses with high-rises, turning dirt roads and mud pits into high-speed overpasses, and evolving from three-wheel buses to subway and private car.
Twelve years is not a short time, which can make Changsha change with each passing day, and can also make the cooperation between enterprises continue to flourish. If time is the most loyal recorder, then CN company is the most persistent witness of the development of Dupule Pump industry.

Twelve years, starting from the common pursuit of quality
In 2010, CN Company hoped to find high-quality automotive air-conditioning parts suppliers in China. As one of the earliest pioneers in the brushless DC car water pump industry in China, TOPSFLO has been committed to the research and development of high-quality pumps,with mature products and supporting experience of projects. TOPSFLO’s unremitting pursuit of quality and continuous breakthrough in technological innovation have deeply attracted customers. After a preliminary understanding of the TOPSFLO pump industry, CN company purchased the first small batch samples. After the test, the customer gave a high evaluation to the TOPSFLO pumps in terms of batch consistency, noise value, design, and other aspects. Thus, the prelude to the 12-year cooperation between TOPSFLO and CN Company was opened.
In the past twelve years, TOPSFLO and CN Company have changed from a simple cooperative relationship to a good friend. Customers said that CN has suppliers all over the world, and has signed numerous contracts with many companies, but the cooperation with TOPSFLO is the most time-tested and baptized.

Twelve years, loyal to the original intention of ” Anxious customer need”
After the outbreak of the epidemic, it is full of difficulties for everyone and every company, and many things are full of uncertainties and challenges. CN originally planned to purchase a batch of water pumps at the end of May 2021. In April, TOPSFLO suddenly received an urgent notice from the customer and needed to deliver the pumps in advance to the beginning of May. This batch of water pumps will be used in the air conditioners of trucks transporting epidemic prevention materials.
Considering the urgent needs of customers, TOPSFLO immediately organized relevant departments to hold an emergency meeting, expedited the procurement of materials, adjusted the production plan, and finally completed production on May 6. However, there are new problems in transportation .Air transportation is the fastest way, but the CN reported that all the flights they booked were empty of space. After learning this news, TOPSFLO logistics department immediately consulted our domestic forwarder and closely followed up the space situation.The hard work paid off, one company changed the flight plan, and these pumps successfully boarded the flight to the destination.
In June, CN sent an email to thank TOPSFLO for its support during the epidemic. They received this batch of water pumps in advance and these water pumps have been officially used in trucks transporting epidemic prevention materials. Every time we communicate with CN, we can feel their trust and support for TOPSFLO. And this email made the hearts of TOPSFLO rise with pride and joy.

Twelve years, a long-standing tacit understanding
On Christmas Eve, in order to express our blessings and thanks to our customers, TOPSFLO specially made a festive video to share with CN and CN’s reply made us feel warm.

Hi kayla
Indeed it has been a very difficult year, God allow this pandemic to end soon, but after that, it will be to start year zero.
How beautiful is this video! How beautiful, the whole TOPSFLO family! It has moved me warmly, and it is not just a cliché, it is reality.
I wish all TOPSFLO and you in particular the greatest successes in the new year.
I greet you with much affection!!!

In the past 12 years, Changsha has not been what it used to be, and the development of CN Company is even more prosperous. While sincerely happy for everyone’s common growth, TOPSFLO Pumps has always adhered to the original purposes- “provide safe, continuous and stable fluid power”, and “become the global leader in high-end micro-pump brands”. To “become the global high-end micro pump brand leader” for the development vision, ensure the highest quality products, achieve the most satisfactory results, and promote the most far-reaching development. It is said that the original intention is easy to obtain, but it is always hard to maintain. In the beginning of the 12th year, TOPSFLO Pumps has not changed its heart.

TOPSFLO’s outstanding performance has secured a prestigious client in the global thermal management industry

Recently, LD company, a renowned global thermal management solutions provider, sent a three-person delegation from its Shenzhen facility to conduct an on-site visit and inspection of TOPSFLO. During the tour, LD’s representatives expressed alignment with TOPSFLO’s commitment to high-end positioning and serving top-tier clients, which mirrors LD’s own aspirations. Both companies share a dedication to becoming industry benchmarks and achieving the long-term goal of creating century-old enterprises.

LD, known as the preferred thermal management solutions partner for major global equipment manufacturers like Siemens, Philips, and Tesla, decided in 2019 to replace its Japanese pumps with China-made micro brushless DC water pumps at its Shenzhen site. Upon recommendations from its European and American clients, LD discovered TOPSFLO, a company known for quality. However, LD’s criteria for supplier selection went beyond reputation alone.

To ensure only the highest quality thermal management cooling pumps, LD established three testing platforms in the US and China, performing rigorous daily evaluations on various performance aspects. These tests included ON-OFF accelerated cycle aging, 80°C high-temperature endurance, and flow and pressure assessments. LD’s R&D team closely monitored pump performance in real conditions.

After a year and a half of intensive testing, TOPSFLO emerged as the top choice, outperforming other brands in quality and durability. LD representatives particularly noted TOPSFLO’s exceptional performance in the 80°C test, where its pumps maintained the lowest temperature rise among all models, reducing heat generation and enhancing electronic component reliability. Remarkably, TOPSFLO’s thermal management cooling pumps also demonstrated greater high-temperature resilience than the existing Japanese pumps, which often failed under similar conditions.

Satisfied with the test results and the proven advantages of TOPSFLO’s pumps, LD’s Shenzhen factory representatives conducted a detailed follow-up visit. The evaluation was overwhelmingly positive:

1. ESD Control Excellence: LD recognized TOPSFLO’s leadership in anti-static control, supported by an ESD and dust-free facility compliant with ANSI ESD S20.20 2014 standards, minimizing static-related electronic failures.
2. Operational Standards: TOPSFLO’s adherence to TUV IATF 16949 and ISO9001 certifications, along with its pursuit of “zero defect” quality, received strong praise.
3. Automated Production: TOPSFLO’s automated lines, equipped with over 100 advanced manufacturing and testing systems, impressed LD for their efficiency and precision in electronic, motor, and pump assembly processes.
4. Advanced R&D Capabilities: LD commended TOPSFLO’s R&D and testing facilities, which include four laboratories certified to CNAS standards, and a seasoned engineering team that delivers both standard and custom solutions.

Additionally, LD offered valuable insights on areas like waste management and staff training, aiming to guide TOPSFLO toward continued improvement. This collaboration promises a dynamic partnership grounded in shared values. TOPSFLO is committed to building on this trust by delivering products that meet high-quality standards and creating added value for clients who prioritize excellence in thermal management cooling pumps. As our corporate philosophy states, “To ensure the best quality of each TOPSFLO pump.”

How to choose a food grade dc water pump

At present, there are many kinds of food-grade water pumps on the market, and it takes a little effort to choose them. So, how can you choose a pump that meets your needs, also known as your heart? Generally speaking, a good food-grade water pump must meet the following 5 points:

1. Food grade certified material
Because food-grade water pumps are used to transport food, beverages, and drinking water that customers drink. Therefore, all materials in direct contact with fluids must be food-grade certified materials, otherwise they are harmful to human health. Such as through WRAS, FDA food certification: FDA is recognized as one of the world’s largest food and drug management agencies, strict requirements; WRAS is the certification of drinking water safety in the UK.

2. Customized size and interface
According to the actual situation of the equipment, determine the size of the pump or the size of the space reserved in the equipment, and then consider whether it is a threaded interface or a Babaokou. It is also necessary to determine the direction of the water inlet and outlet, and the diameter of the pipe. According to the needs, the matching pump can be customized to maximize the performance of the pump and the equipment to achieve the best quality.

3. Cost saving
According to the application requirements, calculate the requirements for the working voltage, current, etc. of the food-grade water pump. Select the same voltage as the power supply mode of the device; select lower power consumption under the premise of guaranteed functions, etc. Choosing a pump whose performance is competitive enough for the application can save you a lot of money over choosing a more powerful pump.

4. High temperature resistance
Small household appliances such as hot drink machines and coffee machines transport high-temperature media for a long time. Therefore, when choosing a water pump, the ambient temperature and working fluid must be taken into account. For applications that require a 100°C operating temperature, a pump with a maximum operating temperature of only 50°C cannot be selected. And to consider the long-term, long-term high temperature food-grade water pump is the first choice.

5. Custom function
Choose a water pump that can realize customized functions, such as overvoltage protection, overcurrent protection, idling protection, PWM/5V intelligent speed regulation, speed feedback and other customized requirements.

What is a food grade water pump?

TOPSFLO dc water cooling pump successfully helped China fight against the epidemic

Recently, Molly, the sales engineer of TOPSFLO received feedback from H company in the medical industry. The customer expressed high satisfaction with the brushless DC medical Cooling pump provided by TOPSFLO and the active cooperation and meticulous service of the team.
Enterprise H focuses on the fields of life science and biotechnology, providing real-time, panoramic, and full-life-cycle life digital equipment and systems for industries such as precision medicine, precision agriculture, and precision health. At present, it has more than 1,700 employees, and its business layout covers more than 70 countries and regions on six continents. It has established scientific research, production bases, training and after-sales service centers in many countries and regions around the world. It is one of the global enterprises with independent research and development and mass production capacity of clinical high throughput gene sequencer

In late 2021, TOPSFLO received a call from the customer for the first time and needed a water cooling pump used on a gene sequencer for gene and virus screening in major hospitals, laboratories and scientific research institutions. The customer used a Japanese water pump before, however the technical service was not in place, and the lead time was very long so that the project progressed very slowly because of the pump supply problem.
The customer said that the gene sequencer is a high-tech product, and not many really have R&D strength. In the early years, the genetic testing market was basically monopolized by foreign countries. H company invested more than 700 R&D people committed to make high-end products belonging to China. Since the gene sequencer needs to rely on the DC water pump to cool the chip platform, it is very important to ensure the stability of the water pump as the core component of the application.
Although customers known that Topsflo has always been strict with itself in accordance with international standards and has cooperated with many famous customers in the medical industry, and its products can well meet the needs of the medical industry. However, customers are still full of concerns about using domestic water pumps to replace the original Japanese brand.

In view of the particularity of the industry, customers have very high requirements on the quality and batch consistency of pumps. After in-depth communication with H company, Topsflo sales engineer Molly recommended two brushless DC water pump TL-B10&TL-C01 to the customer, and urgently provide samples to customers three times for testing and further verification.

Topsflo micro pumps strictly adopt raw materials imported from Japan, and never use any recycled materials. All plastic parts must pass the water sampling test with a burst pressure of 28bar, high and low temperature sampling test. All finished products must pass the 100% comprehensive test, 100% air tightness test , 100% burn-in test… 38 strict quality inspections ensure the stable and reliable performance of each pump.

Traditional AC Pump VS New DC Solar Pump

At present, water pumps used in solar energy equipment on the market are roughly divided into two types: alternating current circulation pump and direct current solar hot water pump.

The traditional separate AC circulating pump system, that is, the household electricity 220V/110V directly supplies water pump with uninterrupted power supply, to realize the circulation of cold and hot water.

The new energy and DC solar hot water pump circulation system directly uses 5W, 10W, 15W, 25W solar panels to supply power to water pump and keep continuously work, and to realize the exchange of cold and hot water.

Compared with the traditional separated AC circulating pump, the new energy DC solar hot water pump has the following advantages:

1. Energy saving, environmental protection and safer: using solar panels to supply power directly, low power consumption can be started, no need to use household AC power supply, very energy saving (if install DC solar energy system in the developed countries in Europe and America, the government will give certain subsidies accordingly) . The water pump itself is DC low voltage, which is very safe to use, avoiding the risk of AC pumps).
2. Long service life: DC circulating pump adopts the most advanced magnetic drive method, and the lifetime is more than 20,000 hours. Compared with the lifetime of AC pump of about 6,000 hours, it is greatly increased, and the average cost-effectiveness of the customer’s use is greatly improved.

3. Low noise: DC circulating pump is an isolated centrifugal pump, the friction between the bearing and shaft is very small，so the working noise of the pump is lower than that of AC pump, and quieter.

4. Small size: DC pump is about 1/3 the size of the traditional AC pump, which is more convenient to install and use;

5. Integration of functions: The traditional AC screw irrigation pump needs a photovoltaic pumping inverter to realize MPPT function, while the new DC solar pump can realize MPPT function without the inverter (such as  TOPSFLO TD5 solar pump), which reduces the cost.

(MPPT function analysis: Control and adjust the operation of solar water pump, drive water pump with electric energy emitted by the solar array, and adjust the output frequency in real time according to the change of the sunlight intensity, so that the output power is close to the maximum power of solar battery array.)

In a word, the advantages of DC brushless water pump over traditional AC water pump are very obvious, especially its energy-saving features are valued and welcomed by more and more countries, and it is gradually replacing the use of traditional AC water pump. TOPSFLO’s dedicated solar hot water circulating pump is DC brushless solar pump.

Five advantages of TOPSFLO TD5 solar hot water circulating pump

At present, TOPSFLO TD5 solar hot water circulating pump has been widely used in New Solar Whole House Water Heating System, Solar Water Heater, Hot Water Circulation, Cooling System and other fields, and has been recognized and praised by customers. So, what is the charm of TD5 solar hot water circulating pump to be favored by the market?

• First, all stainless steel solar hot water circulating pump. Made of food grade stainless steel, it is very safe and reliable, and there is no leakage of dangerous elements. Traditional copper, lead, and brass products contain more or less lead in a certain proportion, and high lead content will have adverse effects on our health. All-stainless steel pump body of TD5 can withstand high temperature of 110℃, and system pressure can be up to 10bar.   

• Second, low power, soft start. TD5 can be powered directly by photovoltaic panels. 6V low voltage start, 2W low power start, and water pump can start and work normally when the sunlight is weak in the morning. The pump starts up reliably even after a prolonged shutdown. The general solar pump on the market cannot start with such low voltage and low power, and it is easy to burn the machine with too low power.

• Third, maximum power point tracking (MPPT function). Every three seconds, the processor modifies the operating point on the PV panel’s voltage-current curve to find the point of optimal performance. No separate performance equipment is required, TD5 solar pump automatically finds the optimum operating point for maximum performance under any given light and temperature conditions. Compared with general pumps on the market, the efficiency can be improved by 30%-50%.

• Fourth, long lifetime. Using high-efficiency ECM brushless DC motor, maintenance-free, with 30,000 hours lifetime, and advanced magnetic drive technology, static sealing, never leaking.

• Fifth, multiple protections. Overvoltage protection – pump stops working in the case of overvoltage, and restarts when it is lower than the voltage;

Locked rotor protection – when the rotor is blocked by debris, it will automatically protect and stop, and automatically resume work after the debris is removed;

Polarity protection – the polarity of the power supply is reversed, the water pump will not work, but it will not cause an irreversible fault.

Generally, the pumps of domestic manufacturers do not have these functions.

As a renewable clean energy, solar energy is widely used in various fields. To produce the best pumps with the highest standards, TOPSFLO adheres to the concept of energy saving and environmental protection and vigorously develops and researches, resulting in the amazing advent of TD5 solar hot water circulating pump. As the only professional solar water pump supplier in China, TOPSFLO will continue to improve technology, innovate and make breakthroughs, turn customer recognition and support into continuous forward momentum, and strive to become a leader in the global micro pump industry.

TOPSFLO Water Heating Mattress Circulation Pump Solves Easy Stuck Problem

Recently, TOPSFLO sales manager, Susan received an annual new order of 100,000 units from a well-known Korean customer in the water heating mattress industry, and also received great affirmation and recognition from them in email. They reflected the 150,000 units of  TOPSFLO Quiet brushless circulating water pumps used in the past 3 years, are far superior to other pumps they have used before. With high quality and batch consistency with zero defect rate of stuck problems, TOPSFLO quiet pump C03 solved their industry problems caused by “easily stuck” previously.

Water Heating Mattress, also known as temperature-controlled plumbing mattress, consists of two parts: a plumbing mattress and a water reservoir. In recent years, the advent of water heating mattress has allowed more people to enjoy comfortable sleep, and has gradually developed into a household necessity. The working principle is that the water is heated through the reservoir, and then pumping to the plumbing mattress for heating by the brushless mini DC circulating water pump. Because the medium is water, it does not produce any electromagnetic radiation, especially suitable for the elderly and children.

As an indispensable power source for the liquid circulation, the circulating water pump has a direct impact on the pros and cons of the plumbing mattress. At present, many plumbing mattresses on the market are prone to the problem of uneven heating after running for a period of time, or the host cannot start when the plumbing mattress is put away for a year after being used in winter, which is caused by the stuck mini water pump. It not only affects customers experience, and also has greatly reduced the brand reputation, and many plumbing mattress manufacturers and customers have been suffering from it.

Facing the long-standing industry problem, the customer’s team inspected a number of  micro pump manufacturers and tested a variety of miniature brushless circulation pumps, but the results were unsatisfactory. Finally, under the recommendation of its partner company, the customer learned about TOPSFLO water heating mattress pump. After understanding TOPSFLO technical development capabilities and R&D strength, the customer initially affirmed its strength, and further proposed to TOPSFLO technical team to solve the industry problem “water pump stuck”.

The problem has not only plagued plumbing mattress customers for a long time, but also a common problem faced by the micro-pump industry. But TOPSFLO R&D team embrace this challenge and always hold the intention of truly solving problems and creating value for clients, continues to conduct in-depth research and try to solve the stuck problem from various aspects. After more than 1 year of long-term research and multiple rounds of verification, breakthroughs are finally made in the following three aspects to solve the industry stuck problem.
1.TOPSFLO adopts high-quality raw materials and high-precision molds imported from Japan, to ensure the high precision and high batch consistency of the rotor bearing & shaft, to prevent the dimensional deviation caused by the precision problem and cause the stuck, eventually ensuring the high precision and high quality of the products with Seiko quality and batch consistency;
2.On the condition that ultra-quietness and high batch consistency are ensured, the structure of the pump is more rationally designed to reserve a space to allow more impurities to pass through. This is due to the strength of TOPSFLO technical research in the pump industry for nearly 20 years and the accumulation of long-term customer service experience.
3.The combination of extra large torque motor and the electronic starting scheme, makes large starting torque. Even if there are tiny impurities, it will not cause stuck.

What industry problems does the TOPSFLO smart toilet booster pump help internationally renowned bathroom manufacturers solve?

Since its entry into the smart toilet industry in 2018, TOPSFLO Pumps has had in-depth and stable cooperation with well-known domestic and foreign brands such as ROCA, GEBERIT and COMA. And it has accumulated rich industry experience and high-end customer service experience in structural design, parameter modulation, and equipment matching in the early stage of product development.

Industry barriers appear, and innovation in the smart toilet industry is imminent

In 2018, hidden smart toilets without a tank were popular abroad. N·A, a well-known European sanitary ware manufacturer, contacted the overseas sales engineer of  TOPSFLO Pumps: hoping to solve its problems in smart toilets by using small and high-efficiency miniature brushless booster pumps. The problem encountered in the new project – the problem of insufficient water pressure in the pipeline leading to poor flushing. This problem is also a common problem that the entire smart toilet industry needs to solve urgently.

Previously, external water tanks were generally used in the industry to solve the problem of insufficient water pressure, but the external water tanks caused the size of the smart toilet to be too large, which could not meet people’s increasing pursuit of simplicity and smart home in life. Innovation in the smart toilet industry is imminent.

N·A is a well-known bathroom manufacturer in Europe, with 3 production bases in Switzerland, Romania and Thailand. And design and produce smart bathroom products for internationally renowned brands such as Laufen, Grohe, Geberit, etc. As a well-known company in the industry, whether N·A can quickly make a breakthrough in this innovation is the key to its core competitiveness in the market.

Micro brushless DC pump has become the core key of the smart toilet industry

After continuous research and development and verification, N·A found that as long as the water pump reaches certain parameters, it can break through the water pressure limit. Even if no external water tank is installed, it can still have a strong impulse. Therefore, the problems of insufficient water pressure in the pipeline and external water tank are easily solved. .

However, if the installed water pump fails, it will cause the entire smart toilet to fail to operate normally, and the resulting maintenance costs and loss of brand reputation will far exceed the cost of a water pump itself. Therefore, when choosing a supplier of miniature brushless DC water pumps, N·A has very high audit standards and extremely strict quality requirements – not only have high requirements on the supplier’s production scale and company strength, but also the high water pump. Quality requirements come first.

After testing more than ten models of water pumps on the market, N·A was finally selected in its “long-term life test”, which has the best test effect and the most stable and reliable quality – the high-end smart toilet Booster water pump TL-C04.

TOPSFLO intelligent toilet booster pump helps customers solve industry problems

TOPSFLO intelligent toilet booster pump TL-C04 can realize 0Mpa start-up in an independent water pressure system, and the start-up time is as low as 0.1s, which is more than 5 times higher than that of water pumps with the same parameters in the industry. Impact force, avoiding flow loss to the greatest extent, allowing users on high floors and areas with low water pressure to use smart toilets to break through the water pressure limit, helping N·A to successfully solve the problem of “insufficient water pressure in pipes leading to unclean flushing”.

In the follow-up stable cooperation, the high standards of product quality, the in-depth study of core technologies, and the management and control capabilities of factory automation production lines have been recognized by TOPSFLO Pumps. Long-term product batch consistency and high-efficiency service have enabled our company to gain more trust and support from customers.

As a professional manufacturer of intelligent toilet booster pumps, TOPSFLO Pump has always kept pace with the world’s latest cutting-edge technologies since its establishment, based on the highest international standards, and strictly follows the German TUV Rheinland IATF16949 quality management system. With high-quality products and comprehensive solutions, we help customers achieve new breakthroughs in the smart toilet industry and achieve high-end brand power.

In the future, we will continue to take customer recognition and support as our goal and driving force, continue to focus on the R&D and manufacturing of high-end miniature brushless DC pumps, and bring higher-quality miniature pump products and solutions to more customers.

What is a Smart Toilet Pump

The problem of insufficient water pressure in the pipeline leads to the smart toilet not being flushed cleanly, which is a common problem to be solved urgently in the entire smart toilet industry. Until then, external water tanks were generally used to solve this problem, but because the overall size was too large, it could not meet people’s increasing pursuit of simplified and intelligent home furnishing. Under the market development trend of simplicity and intelligence, the smart toilet booster pump has become the key to breaking the deadlock.

For smart toilet manufacturers, choosing a good smart toilet booster pump can not only achieve good flushing effect, save space, solve the problem of insufficient water pressure, but also improve their own brand power and user reputation, which is quite important.

As early as 5 years ago, when smart toilets were popular abroad, TOPSFLO Pumps has launched the smart toilet booster pump TL-C04, which adopts 0 water pressure start technology, which can realize 0Mpa start in an independent water pressure system, and the start time as low as 0.1s. It is more than 5 times higher than the water pump with the same parameters in the industry, and the peak water volume is released instantly, allowing users on high floors or low water pressure to use the smart toilet to break through the water pressure limit, and successfully solve the problem of unclean flushing caused by insufficient water pressure in the pipeline.

At present, TOPSFLO Pump has maintained long-term and stable cooperation with ROCA, LAUFEN, GEBERIT, COMA and other well-known smart toilet companies at home and abroad.

How to Choose a Car Preheater Circulation Pump Supplier

According to the research, the wear to the car engine caused by a cold start in a low temperature environment could be equivalent to the wear caused by the normal running for 200 kilometers, and nearly 60% of engine wear is from cold start. Under this situation, the emergence of car preheater has successfully solved this problem, and has been recognized by more and more people. So as the key component of the car preheater, car preheating circulating pump is absolutely quite important.

According to the data from CPCA, the cumulative national car sales in the first quarter of 2021 is 5.092 million, a year-on-year increase of 68.8%. The car preheater industry is ushering in a stage of rapid development, and there are more and more manufacturers of car preheating circulating pumps. However, the product quality of pumps is uneven, seriously affected the development of the car preheater industry. So how to choose a high-quality car preheating circulating pump supplier as a car preheater manufacturer? Let’s turn to the idea and thoughts shared by the Topsflo engineer who has been in deep ploughing car electronic pump industry for more than ten years.

Firstly, choose a car preheating circulating pump supplier with its own independent R&D and factory. Generally, these companies have a complete organizational structure, management, and service system. Therefore, they will have a strong guarantee on product quality, delivery time, custom development, etc.

Secondly, choose a supplier with stable cooperative relations with world-renowned car companies or key OEMs, as these well-known companies have their own strict and complete supplier review system. Therefore, these car preheater circulating pump suppliers who can be selected by major car manufacturers and could reach a long-term stable cooperative relationship with them, their comprehensive strength and product are definitely guaranteed.

Finally, choose a supplier who can provide customized services. As we all know, different vehicles and different application environments will have various requirements on pump’s material, parameters and process, so it’s quite vital to choose to pump suitable for given product. And the customized service can provide the best match for car preheaters.

In conclusion, I believe that you already have a certain understanding of how to choose a high-quality car preheater circulating pump supplier now. Only a well-chosen pump can improve the efficiency of the car preheater and help preheater to start easily in extreme environments, reducing the wear and tear. On the contrary, the use of inferior water pumps will not only fail to achieve the ideal preheating effect, but also will accelerate the wear of car engines and affect the brand power of car preheater companies.

Why Brushless DC Water Pump will Become a New Trend to Replace AC water pump of Fluid Industry in the Future？

In recent years, DC motor water pump have been well known by many companies because of its small size, low power, more safety etc.. Many engineers will consider upgrading their AC water pumps to DC water pumps. Today, let me take you all to find out “why brushless DC motor pump will become a new trend to replace AC water pump of fluid industry in the future”.

First of all, brushless DC pump adopts electronic components for commutation, and detects the position of the permanent magnet through programs. Unlike the traditional AC water pump motor, which will wear out when rotating the carbon brush, the brushless DC water pump don’t need the use of carbon brush commutation, which is a new water pump technology.  There may still be many people who do not know this new pump technology. Let’s take a closer look at the advantages of brushless DC water pumps:

1.Brushless DC water pump more safety
The common power supply for brushless DC water pumps is low-voltage 24V or 12V, which is far lower than the human body safe contact voltage of 36V. It will not cause any damage to the human body and organisms in case that the wire is aging, leakage, etc. However, the AC water pump is high-voltage electricity, once the wire is aging or leaky, it will cause great harm to human body and organisms.

In many industries, the use of AC water pumps will have potential safety hazard, such as swimming pool equipment, fish tank pumping, and dishwasher equipment, once the electricity leaks, it will cause safety hazards to the human body. But brushless DC water pumps do not have this safety hazard problem.

2. Brushless DC pumps are more energy efficient
The traditional AC water pump with 3000L/hour (5L/min) flow rate needs 100W+ power while the water head is less than 3M. For this reason, many manufacturers falsely standardize the parameters (the normal error of pump parameters is about ±5%, and the AC water pump is far more than that). As a result, when you use the water pump, the energy consumption is very large, because the friction loss of the AC water pump motor rotating carbon brush is very large. The brushless DC water pump has a flow rate of nearly 12000L/hour (200L/min) at 100W, and the water head is still 5M. That’s because the brushless DC pump has very low loss and high efficiency.

After one year, with the same power use, you can even save money for several water pumps on your electricity bill by using a brushless DC water pump.

3.Brushless DC pumps have longer lifetime and more silent
Brushless DC water pump adopts the combination of ceramic and carbon fiber graphite shaft sleeve, there is basically no friction and no noise during use，which greatly increase its lifetime. This is not the case with traditional AC water pumps. As long as the motor rotates, the carbon brushes will wear out. When the pump runs to a certain point, the wear gap of the carbon brushes will become larger, and the noise will increase accordingly. After hundreds of hours of continuous operation, the carbon brushes will not be able to commutate any more.

4.Brushless DC water pump generates less heat
The heating of the water pump is inevitable. If the efficiency of the water pump is low, surely the extra power consumed will be used for heating. Due to the high voltage, the traditional AC water pump uses very thin copper wire and can only use very thin copper wire to wind the coil, so the electrical resistance will be large, the heat will be severe, and the very thin copper wire cannot use high temperature resistant enameled wire.

Micro Brushless DC water pump has a low voltage, uses a very thick copper wire, which with high temperature resistant, so that it can withstand high temperatures and has a low temperature rise. Anyone who understands electronics knows that electrical resistance depends on the thickness and length of the copper wire.

The above are the main four advantages of brushless DC water pumps compared with traditional AC water pumps. Of course, in some specific environments, DC brushless water pumps have more advantage, I will not give examples here. I believe that in the near future, as people use more and more brushless DC pumps, they will have a better understanding of them.

Low voltage DC pump or high voltage AC pump which is more suitable for us to use?

Before starting this question, let us understand what is water pump first? Waterwheels, tackles and other water-carrying tools are the prototypes of water pump in ancient times. With the development of production and people’s understanding and mastery of the laws of nature, these ancient water-carrying tools have gradually developed into today’s water pump.
Water pump is a mechanical device used to lift liquid, transport liquid or increase pressure on liquid. Now the water pump, as a kind of general equipment, has been widely used in various fields of daily life. For example, in agricultural production, pump are mainly used for irrigation and drainage. Our country’s agricultural area is vast, and a large number of pumps are needed in agriculture every year. Our country is also a big manufacturing country, and pump are also needed to transport all kinds of liquids in the food industry. It can be said that where the liquid needs to be transported, the pump will be used! The importance of the water pump to the water delivery equipment is like the heart to the human body. It is the core part of the water delivery process. Pump is so important and there are so many types, we equip the equipment with a suitable pump so that the equipment can be used to the best effect.

We simply start from the voltage range, and generally divide the pump into low voltage DC pump and high voltage AC pump, so which one is more suitable for us? This article will start a chat with everyone about the structure, characteristics and scope of application of the two types of pumps:
High voltage AC water pump generally refer to AC 220V, 380V and other AC power supplies (industrial use). The working principle of the high voltage AC water pump is mainly to use the periodic change of the inner volume of the working pump cavity to transport the liquid.
Maybe everyone is unfamiliar with high voltage water pump, but in hot summer, we can all see it in sprinklers on the street, pumping machinery, and fire sprinkler device on fire truck. Mainly used in agro-industrial fields such as liquid spraying, spraying and irrigation.
Taking the reciprocating type as an example, the volume in the pump cavity is changed by the reciprocating piston or plunger, and the process of inhaling and pressing out the liquid is completed to achieve the purpose of conveying the liquid. The structure is shown in the figure:

The characteristics of the high voltage AC water pump are as follows:

1.High voltage current. When connecting to 220V, 380V power supply, the insulation requirements are extremely high, and special attention should be paid to the problem of wire damage. Once the wire is damaged, it is very likely that electric shock, leakage and other safety accidents will occur.
2.Low lifespan, not resistant to high temperature. The high voltage AC pump motor generally uses a copper-clad aluminum wire core, and the stator coil winding wire diameter in the motor is relatively thin and the number of winding turns is large. When the motor is working, the internal temperature of the product is generally as high as 120 degrees or more. And because most of the high voltage AC pumps use electricity in urban areas, the voltage is relatively high. To make water pump with the same power density, it requires much more steel and copper than Low voltage DC brushless pump, and the efficiency is not high, and the product has poor heat dissipation, so it is not suitable for use in high temperature environment.
3.Large size. Due to its own structural design and application field, the size of the high voltage AC pump will be larger than that of the low voltage DC water pump.
4.High noise. The high voltage AC pump currently uses the motor technology of the early years, and it is related to its own steel and copper. As a result, the noise of high voltage AC pump on the market is generally high, the noise gets louder as the user spends longer.

Low voltage DC water pump generally refer to DC 12V, 24V, 36V and other DC power supplies (commercial & households). Low voltage DC water pump involved in this article mainly refers to the brushless DC pump. The brushless DC pump is driven by the brushless DC motor through the magnetic force of electronic commutation, without the use of carbon brushes, and is driven by the brushless carbon brush motor. There is no wear of the commutator and carbon brush, which reduced the noise and prolongs the service life, performance parameters, reliability and consistency have all been improved to a certain extent. The structure is shown in the figure:

Compared with high-voltage AC pumps, brushless DC pumps have the following obvious advantages:
1.Safer. We all know that the safety voltage of the human body is 36V, and the dc brushless water pump uses a low voltage of 12V/24V. Even if the cable is damaged, there is no need to worry about the occurrence of safety accidents caused by electric shock. Moreover, in the case of a power failure, the pump can also be powered by the corresponding battery, which is more convenient.
2.Long lifespan. Brushless motor, no carbon brush loss; especially the brushless motor used by Changsha TOPSFLO, which uses imported precision ceramic shafts and graphite shaft sleeves, never wears out.
3.Lower power consumption. The BLDC motor can accurately feedback the target number of revolutions, torque, etc. Heat generation and power consumption of the motor can be suppressed by precise control.
4.Intelligent control. Built-in intelligent chip, can adjust the flow; realize signal feedback, failure mode feedback, and has multiple intelligent protection functions.
5.Small size, higher efficiency. The brushless DC mini pump has a built-in variable frequency brushless DC motor, no carbon brush commutation, no mechanical friction heating, low power, and small temperature rise. It solves the problems of low energy efficiency, large size and high noise of the high voltage AC pump. Generally speaking, the efficiency of the brushless pump of the same volume can reach 2~3 times that of the AC pump, and the volume is 1/3~1/2 of the AC pump.
6.High temperature resistance liquid. The temperature of the liquid generally used in the brushless DC pump on the market is not higher than 70 degrees. At present, Changsha TOPSFLO Pump Co., Ltd. can customize brushless DC centrifugal pump with high temperature resistance up to 125 degrees.
7.100% waterproof, never leak. The rotor is integrally formed, the stator and the rotor are completely isolated, and the static seal replaces the traditional shaft (dynamic) seal. The liquid is completely isolated from the motor and never leak. And it can be fully submersible and 100% waterproof, effectively improving the service life and performance of the pump.
8.Low noise. Under the same performance, the brushless DC centrifugal pump of Changsha TOPSFLO will be 15-20dB lower than the high voltage AC water pump with the same performance.

Because the brushless DC pump has many advantages, such as reliable operation, convenient maintenance, high efficiency and intelligent control. Its application range has gradually replaced the application field of high voltage AC water pump, and has spread to all fields of the national economy and people’s daily life. For example, our daily water dispenser, water heater, smart toilet, and car; as well as commercial appliances such as medical equipment, beauty equipment, and irrigation equipment.
Through the above analysis, the editor believes that with the continuous improvement of the level of social science technology and the quality of life, brushless DC pump are more suitable for our use, and gradually become the mainstream, replacing most of the fields that require high voltage AC pump. However, each type of pump has its own characteristics, and no one type of pump can be suitable for application requirements in all fields, only the ones that fit the development needs are the best.
Well, that’s all we’re going to talk to everyone about today. If you have different views and suggestions, you can leave us a message, and look forward to communicating with you!

What is a Water Heater pump?

In modern bathrooms, electric water heaters are now a common sight, providing much-needed convenience for daily washing routines. These devices are powered by electricity to heat water and are considered one of the three main types of water heaters, alongside gas and solar water heaters. Electric water heaters are typically classified into three types: storage-type (also known as thermal storage or volumetric type), instant heating, and semi-storage (quick heating) types, based on their heating method.

How Does an Electric Water Heater Work?

The operation of electric water heaters is based on a simple principle. Cold water enters the storage tank from the water supply system under pressure. Inside the tank, a heating element heats the water, with the thermostat and timer controlling the process. As the water warms up, it rises to the top of the tank. When you turn on the hot water tap, cold water enters the bottom of the tank, and the hot water at the top is pushed out due to atmospheric pressure.

Installation Guide for Electric Water Heaters

1. Choosing the Right Location: The water heater is typically installed in the bathroom, and it’s crucial to mount it on a load-bearing wall as required by most manufacturers. A load-bearing wall is generally a thick, solid wall made of materials like brick or concrete. If a non-load-bearing wall such as foam brick or hollow brick is present, professional reinforcement is necessary.
2. Proximity to Drainage: Ideally, the electric water heater should be located close to the drainage system but away from the toilet area to ensure proper functionality.
3. Allowing for Maintenance Space: It’s important to leave enough space for future maintenance. Typically, the area to the right of the water heater should be at least 30cm. If the unit is partially or fully installed in the ceiling, the cover panel must be removable for easy access during maintenance.
4. Pressure Relief Valve: Always install a pressure relief valve with a discharge pipe leading to the floor drain to ensure safety and prevent over-pressurization.
5. Pipe Installation Requirements: Ensure the inlet and outlet pipes are properly spaced, with at least 30cm from the bottom of the unit for the inlet pipe, 10cm between the inlet and outlet pipes, and 15cm between the cold and hot water ports on the mixing valve.

The Importance of a Water Heater Pump

A water heater pump (electric shower booster pump) is a compact centrifugal pump designed to enhance water pressure in electric water heaters. The pump works by rotating the water at high speeds inside the pump cavity using an impeller, creating centrifugal force to boost the water pressure. This ensures that the water pressure coming out of the heater is higher than the incoming supply pressure, allowing users to enjoy consistent water flow and adequate pressure, especially during showers.

Where to Install the Water Heater Pump

Typically, the electric water heater pump is mounted inside the electric water heater using a sturdy bracket and is connected to the water inlet pipe. It helps by pumping cold water into the heating element for efficient water heating.

How to Choose the Best Water Heater Pump

When selecting a water heater pump, manufacturers must work closely with pump suppliers to ensure the right pump is chosen for each water heater model. Most commonly, manufacturers opt for DC 12V, 24V, or 36V pumps. Brushless DC pumps, in particular, offer several advantages:

1. Improved Efficiency: Brushless DC motors are 30% more efficient compared to traditional AC motors.
2. Intelligent Control: These pumps have built-in smart chips that adjust water flow and temperature based on real-time requirements, offering a customized shower experience.
3. Stable Voltage: The 12V/24V DC shower booster pump is compatible with the water heater’s internal power supply, ensuring constant voltage and smooth water flow, regardless of electricity consumption peaks.
4. Quieter Operation: Compared to AC pumps,BLDC pumps generate significantly less noise, improving the comfort of your shower.
5. Longer Lifespan and Compact Design: These pumps boast a lifespan of up to 20,000 hours and are smaller in size, which enhances the overall design and durability of the water heater system.

How to Choose a High-quality Miniature Brushless DC Water Pump Supplier?

Miniature brushless DC pumps are widely used as fluid conveying functional components in various equipment due to their advantages of small size, high efficiency, long life, safety, and quietness. The water pump is to the machine application equipment, just like the heart is to the human body, the performance of the water pump directly affects the normal operation of the whole machine application equipment. So, how to choose a high-quality miniature brushless DC water pump supplier? Here would like to share with you some useful tips, mainly from three aspects: electronic components, rotors and batch consistency, for your reference.

Electronic Components  

Presumably many purchasers of water pumps have been troubled by electronic failures and burn-in. The reason is often that there are problems with electronic components. The components of the water pump are the core part of the water pump, and high-quality water pump suppliers must use high-quality electronic components. So how to evaluate the pros and cons of suppliers’ electronic components?

        1.Choose a well-known brand. The electronic components from big manufacturers and famous brands usually are implemented with higher standards, have stronger stability for long time running, and with higher efficiency, thus can avoid potential failures to a large extent, and the quality of the water pump will be significantly better than others.  

       2. Evaluate parameter sufficiency margin. In the stage of designing electronic solutions, engineers will calculate the corresponding parameters for different applications and leave sufficient margins, which makes the parameters more stable and the performance of components more reliable.

        3.Professional analysis methods for evaluating key temperature rise indicators. The temperature rise of electronic components has a great impact on the lifetime of the pump, especially when the pump is working at high temperature. Professional water pump manufacturers have specialized analysis instruments and equipment for temperature rise analysis, thus the electronic solution design is more reliable.

TOPSFLO Solutions

More than 90% of the electronic components of  TOPSFLO micro pumps are from international first-line brands, and 100% of the original imported materials can be traced. All components must pass six 100% full inspection processes to ensure their reliability and effectively prevent electronic failures. At the same time, the electronic solutions designed by professional electronic engineers with rich design experience in the automotive industry have sufficient margins, better heat dissipation, lower temperature rise, and higher reliability.

Rotor

After the pump has been used for a period of time, the pump chamber cracks and leaks. Why this happens? Maybe there is a problem with the rotor. When choosing a pump supplier, the quality of the rotor is usually judged by the following three points:

     1.Rotor balance. The unbalanced rotor is one of the main reasons for the high noise of the pump, which directly affects the working performance and lifetime of the pump. The high-quality pump supplier uses the one-piece injection-molded magnetic silent rotor, which is molded at one time, with low rotor unbalance, high precision, no yaw, and no pump wear.

     2.Processing Equipment. To produce high-precision rotors, the water pump supplier should be equipped with a series of advanced processing equipment, such as ultrasonic welding machines, which can ensure the seamless and super-strong combination of the impeller and the rotor; the roundness meter and the roughness meter to ensure the high precision of each rotor , to ensure low noise and high batch consistency, etc.

     3.Experimental development equipment. High-quality pump suppliers should also have independent research and development capabilities, professional laboratories, and test conditions that are higher than industry standards, so that products can have more stable and reliable laboratory simulation analysis and testing from the research and development stage. The development failure caused by the inability of professional means to conduct professional analysis can be avoided.

TOPSFLO Solutions

TOPSFLO miniature brushless DC water pump uses an injection-molded magnetic rotor imported from Japan, which is molded at one time and has a low rotor unbalance. At the same time, the injection mold designed and manufactured by a Japanese-owned company has a precision three times higher than that of its counterparts, and with stable precision control for long-term production. On the other hand, TOPSFLO has four laboratories that meet the standards of CNAS national laboratory accreditation, equipped with international advanced testing equipment, and conducts product testing, verification, simulation analysis etc. that are stricter than the industry standards, which truly guarantees the success and reliability of the official development of the pump.

Batch consistency

The headache of many pump buyers now is that they may buy some samples in good condition, but when purchasing in bulk, there is always the problem of unstable performance, especially the noise of some pumps is higher and others are lower. And sometimes pump buyers will face with different failures, these all bring a lot of trouble to the later stage. So, what kind of pump supplier can achieve good batch consistency? The following 4 points are very important:  

       1.Production equipment: try to choose a pump supplier that has a complete production process, advanced intelligent production lines, and implements refined, visual and intelligent management and control of the entire manufacturing process. Advanced production equipment such as: automatic winding machine, automatic screw machine, imported servo press, ultrasonic welding machine, etc.  

      2.Noise laboratory: high noise and noise consistency are the big problems faced by many pump buyers when purchasing pumps. When examining the pump supplier, try to choose a supplier with a noise laboratory, which can eliminate the interference caused by external noise, ensure that the experimental results are objective and correct, and ensure the batch consistency of noise.     

      3. CPK process capability index: CPK is the ability of the process to ensure quality, which can directly reflect the level of batch pass rate. The larger the CPK value, the more sufficient the ability of the production process to maintain stability. When choosing a pump supplier, you should try to choose the one with the largest CPK value to ensure that each process is 100% tested, such as air tightness test, rotor test, water test and so on.

      4.Noise realization means and evaluation ability: The level of noise is an important factor to measure the quality of a pump. To achieve low noise, the water pump should use a one-piece injection-molded magnetic silent rotor, which is molded at one time. At the same time, a good pump supplier should have excellent noise evaluation ability, and can conduct reliable and effective evaluations from the aspects of mold accuracy, whether the noise level is stable during long-term testing, and the noise consistency of products in the same batch.

TOPSFLO Solutions

In order to ensure the batch consistency of products, TOPSFLO only selects well-known suppliers for key raw materials of water pumps to ensure the batch consistency of different batches of materials; secondly, automation equipment is introduced from Japan, the United States, Germany and other countries to build intelligent production lines and processes batch consistency is highly efficient and guaranteed; thirdly, TOPSFLO adopts 6 full testing processes that are stricter than national standards, and is strictly controlled in accordance with the TÜV Rheinland IATF 16949 quality system standard to pursue “zero defect” quality.

Here above are the tips about the selection of water pump suppliers for your reference, hope they will be helpful to you. For more knowledge about the selection skills of miniature brushless DC water pump suppliers, please feel free to contact us.

What are the working principle and structural characteristics of brushless DC water pumps?

Brushless centrifugal pump is the most widely used category in the pump applications, due to its obvious advantages in high water resistance, high efficiency, long life, low noise and vibration, compact size and so on.

So, do you know how a brushless centrifugal pump works?

How to choose a brushless centrifugal pump to match the equipment?

This article will show you details.

Brushless centrifugal pump working principle

The brushless DC centrifugal pump is driven by a brushless DC motor, and uses the rotation of the impeller to make the centrifugal motion of the water to work.

Before the pump is started, the pump body and suction pipe must be filled with water (without self-priming function), and then the motor is started to drive the impeller and water to rotate at a high speed. The flow channel flows into the pressurized water line of the pump. At the center of the pump impeller, since the water is thrown out under the action of centrifugal force, a vacuum is formed, and the water in the suction pool is pressed into the pump casing under the action of atmospheric pressure, and the impeller rotates continuously, so that the water is in the impeller. Under the action of continuous inflow and outflow, the purpose of transporting water is achieved.

Structure Features of Brushless Centrifugal Pump

Brushless DC centrifugal pump is composed of many components, including pump head, motor stator, shaft, bearing, rotor, impeller and so on.

According to the different performance characteristics of each component, the water pump presents the following structural characteristics:

1.The use of electronic components for commutation does not require the use of carbon brushes for commutation. The magnetic drive of the motor has no mechanical friction and low heat generation. Most low-power pumps can work continuously for 24 hours for a long time, avoiding the traditional brushed motor that cannot be used for a long time, spark generation and current interference during work and operation.

2.After the power is energized, the magnetic force is generated to drive the pump to work continuously, and the service life is up to 30000 hours.

3.Adopting high-performance ceramic shaft, or wear-resistant and mute graphite bearing which is integrated with magnet through injection molding, to avoid wear while making lower noise.

4 The shaft adopts high-performance ceramic shaft with high precision and good shock resistance.

5.The stator and the rotor parts are completely isolated, and the pump shaft from the dynamic seal into a closed static seal, which completely avoids media leakage.

6.The stator and circuit board parts are sealed with epoxy resin, 100% waterproof, therefore the pump can be installed underwater and completely waterproof.

7.The rotor part adopts permanent magnet, and the water pump body adopts environmental protection material.

8.By adjusting the various required parameters by the stator windings, the pump can be operated on wide voltage .

Key points of selecting a brushless centrifugal pump

Brushless dc water pump can be widely used in water dispensers, coffee machines, electric kettles, electric vehicles, solar water circulation system, instant thermal water heaters, solar water heaters, intelligent toilets, water heating mattresses, medical beauty equipment and other fields.

When choosing a brushless centrifugal pump, please be sure to first confirm the match between the pump and the equipment.

♦ First, determine the working voltage, current, head and flow, diameter size. In general, the maximum water head is the static water head with no flow when the water is pumped to the maximum head. If you want to pump the water to a certain height and maintain a certain flow at the same time, the required water head must be higher than the specified pumping height when selecting a pump.

♦ Secondly, determine the volume and shape requirements (threaded interface,  the direction and diameter size of the inlet and outlet, etc.).

♦ Thirdly, determine the working environment (temperature, medium).

♦ Fourth, determin e whether there are other special functional requirements (time control, motion control, pressure control, flow control, speed control, etc.).
