Electric Water Pump from 30W to 500W

Electronic water pump
The electronic water pump consists of a pump housing, impeller, sealing ring, motor housing, electrical plug, motor assembly, bearings, rotor, controller, control seat, rear cover, fixing bolts, etc.
The ECU adjusts the duty ratio through PWM based on feedback signals such as water temperature. The controller connects the harness through electrical fingers, and then controls the motor to drive the impeller and rotor based on the duty ratio, thereby achieving coolant circulation and ensuring accurate control of coolant flow; The sealing ring ensures the sealing between the pump housing, motor housing, controller base, and rear cover; The pump housing, motor housing, and rear cover seal the internal components of the electronic water pump in a dust-free environment, ensuring the reliability of the electronic water pump.

DARE Changzhou, a wholly-owned subsidiary of DARE AUTO, is subordinate to the Thermal Management Division, specializing in the research and development and production of automotive electric water pump and brushless motor. The company is located in Luoxi Town, Xinbei District, Changzhou, with a plant area of 150,000 m². DARE Changzhou has semi-automatic production lines and fully automated production lines, with a total production capacity of 1 million units.

Critical parameters:

Auto water pumps generally have a self priming function, which means that when air is in the pump's suction pipe, the negative pressure (vacuum) generated during pump operation is used to raise the water pressure below the water inlet under the action of atmospheric pressure, and then discharge it from the discharge end of the pump. There is no need to add "water diversion" before this process. A micro water pump with this self priming capability is called a "micro self priming pump". The principle is similar to a micro air pump.

It combines the advantages of self priming pumps and chemical pumps, using a variety of corrosion resistant imported materials to synthesize, with acid resistance, alkali resistance, corrosion resistance, and other properties; The self priming speed is extremely fast (about 1 second), the suction force is strong, the suction distance is up to 5 meters, and there is basically no noise. Exquisite workmanship, not only has a self priming function, but also has a large flow rate (up to 25 liters/minute), high pressure (up to 2.7 kilograms), stable performance, and convenient installation. Therefore, this large flow pump is commonly used in new energy vehicles.
