The WP29 ePump is a high-performance electric water pump, with an intelligent CAN enabled controller. The controller allows the pumps speed to be controlled via CANbus and also allows the pump to give full diagnostic information back to the vehicle. The pump uses a robust and efficient brushless DC motor to ensure performance and reliability. The WP29 is capable of a flow rate in excess of 110 Litres/minute but has full speed control via CAN making it suitable for a wide range of applications.

Due to this unique ability to precisely control the power consumption and performance of the pump it is rapidly coming to the standard pump for cooling heavy-duty hybrid and electric vehicle systems and can be found in electric and hybrid trucks, buses and construction machinery from the world’s leading brands. A special edition of the pump is also available which is ideally suited to water circulation of de-ionised water in hydrogen fuel cell systems.

Available as 12V, 24V or 48V DC input the AVID coolant pump is perfect for high-performance thermal management applications such as electric and hybrid vehicles. In addition to these applications, the ePump can also be found in more conventional vehicles for water circulation in auxiliary cooling circuits to boost the water flow or replace the mechanical water pump completely.
