The working principle of an automotive electronic water pump is as follows:

1. The circular motion of the motor causes the diaphragm inside the water pump to reciprocate through a mechanical device, thereby compressing and stretching the air in the pump chamber (fixed volume);

2. Under the action of the one-way valve, a positive pressure is formed at the outlet (the actual output pressure is related to the assistance received by the pump outlet and the characteristics of the pump);

3. A vacuum is formed at the water pumping port, resulting in a pressure difference with the external atmospheric pressure. Under the action of the pressure difference, water is pressed into the water inlet and then discharged from the water outlet;

4. Under the action of the kinetic energy transmitted by the motor, water is continuously sucked in and discharged, forming a stable flow.

Hebei Nanfeng Group has been committed to the production of electronic water pumps for more than 30 years.

Hebei Nanfeng Automobile Equipment (Group)Co.,Ltd was established in 1993,which is a group company with 6 factories and 1 international trading company.We are the biggest vehicle heating & cooling system manufacturer in China and the designated supplier of Chinese military vehicles.Our main products are high voltage coolant heater,electronic water pump,plate heat exchanger,parking heater,parking air conditioner,etc.

Our factory's production units are equipped with high tech machineries,strict quality control testing devices and a team of professional technicians and engineers endorsing the quality and authenticity of our products.

In 2006,our company has passed ISO/TS 16949:2002 quality management system certification.We also bagged the CE certificate and E-mark certificate making us among the only few companies in the world acquiring such high level certifications.Currently being the largest stakeholders in China,we hold a domestic market share of 40% and then we export them around the globe particularly in Asia,Europe and Americas.

Our electronic water pumps  are specially designed for heat sink cooling system and air condition circulation system of new energy automotive.All pumps also can be controlled through PWM or CAN.
