What Is an Automotive Electric Water Pump

An automotive electric water pump is a motor-driven coolant pump that operates independently from engine speed. Compared with traditional belt-driven pumps, electric water pumps allow:

• On-demand coolant flow control

• Faster engine warm-up

• Reduced parasitic losses

• Improved fuel efficiency and emissions performance

Electric water pumps are widely used in gasoline vehicles, hybrid vehicles, start-stop systems, and thermal management modules.

Applications

Our automotive electric water pumps are suitable for a wide range of vehicle platforms:

• Passenger cars with turbocharged engines

• Hybrid and mild-hybrid vehicles

• Vehicles with start-stop systems

• Auxiliary cooling for batteries, EGR, or turbochargers

OEM vehicle brands and engine applications can be matched according to customer requirements.
