First, what is the brushless DC pump?
　　The brushless DC water pump uses the principle of a permanent magnet brushless DC motor, and an impeller is added to the rotor, and the cavity structure is designed to make the liquid centrifugally move. Since there is no carbon brush friction, no spark is generated; High efficiency, low power consumption, long life and low noise compared to brushed motors.

Second, the characteristics

　　1. Long life, no maintenance, small size and high efficiency, low power consumption.

　　2. Excellent design structure: the water pump head is connected with the rotor cavity of the motor, and the rotor cavity of the motor is completely isolated from the motor stator, so that it is completely waterproof and leakproof and the motor pump is highly efficient.

　　3. Safety and health, environmental protection and energy conservation (because the brushless is electronically controlled to commutate without sparks, no carbon dust pollution).

　　4. The shaft of the pump adopts high-performance ceramic shaft with high precision, good wear resistance and low sound. It can be used for water bed circulation and water bed heating.

　　5. The three-phase DC water pump in the pump can realize PWM speed regulation, analog signal input speed regulation, and potentiometer manual speed regulation, which can realize the head and flow regulation.

　　6. Three-phase brushless water pump with impeller rotor stuck protection, reverse connection protection, overload protection, overcurrent protection.

　　7. Three-phase brushless water pump, the control is soft start, no impact, and the starting power consumption is small.

　　8. amphibious use (installation position is lower than the liquid level).

　　9. The pump can be customized according to user requirements and designed according to customer requirements.

　　10. Pump interface is rich, 4 points thread, 2 points thread, 8mm, 10mm, 22mm, 27mm, etc., can also be customized according to customer requirements

Third, the application

　　1. Water supply function: coffee machine, tea set, water heater/kettle, water dispenser/beverage machine, foot bath, irrigation system/equipment, etc.

　　2. Oil supply function: high efficiency and energy saving, such as: various machine tools, fueling equipment, etc.

　　3. Heat dissipation / water circulation system: medical system / equipment, automation equipment, electronic refrigerator, small indoor and outdoor fountain, solar fountain, aquarium fish tank, hot and cold mattress, etc.

　　4. Drainage function: mobile air conditioner.

　　5. Flush function: Flush glass system/equipment for all types of cars.

　　6. Automobile industry: It is used for engine cold start of automobile engine under 40 degrees below temperature in winter, fuel system antifreeze high temperature 120 degree circulating heat dissipation, electric car, electric motorcycle water circulation heat dissipation.

　　7. Solar photovoltaic energy products: Solar water pumps use solar panels to directly drive water pumps. Solar water pumps have three major functions:

   　1) Energy saving, energy saving 35% than ordinary DC brush water pump;

   　2) Soft start function, the power can be started normally within 1W;

   　3) It is convenient to set the overvoltage protection function;

　　8. Food industry: It is mainly used for dishwashers, coffee pots, water dispensers, and water pump housings. Special food grade high temperature resistant materials can be used. The pump can work normally for more than 100 degrees. Can reach food grade

　　9. Household products: aquarium, fountain, foot, shower, plumbing mattress, computer water cooling system, etc.; DC brushless water pump has the characteristics of low noise, long life and good pressurization effect, which can fully meet the above requirements.

　　10. Mechanical equipment and chemical industry: machine equipment water circulation heat dissipation, chiller circulation heat dissipation, sewage purification treatment, etc.

Fourth, the pump use precautions

　　1. Use a 12V or 24V DC transformer to supply power.

　　2. It should be operated under the specified temperature conditions, and the medium temperature is strictly prohibited. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise of the annulus region, so that the alarm or shutdown occurs when the temperature exceeds the limit.

　　3. Connect the positive and negative poles of the pump power supply correctly so that the pump can start and operate normally.

　　4. Please put in clean water as much as possible to avoid solid objects entering the pump and causing blockage.

　　5. Please do not wrestle the product and affect the performance of the pump.

　　6. The pump is a centrifugal pump. It cannot automatically discharge air. It must be dived or installed below the liquid level when in use.

　　7. The pump should not be idling as much as possible. Because there is no medium lubrication when idling, it is easy to wear.

　　8. Do not use more than the rated voltage, otherwise the pump will be damaged.
