The electric water pump powered by a motor pumps cooling water to the engine to keep it at an optimal temperature.
For hybrid vehicles, its EHRS are widely used to reduce engine warm-up times to improve fuel economy, reduce emissions and provide cabin heating.
The compact integration of controller, motor, and pump enables application on various vehicles.
Optimized control of motor lowers the noise.
Product is available from 30W to 80W (input).
Flow is shut at engine start in order to quickly warm-up the engine.
Valve is designed to open by the force of cooling water flow so that the valve could stay open during power off (for fail safe).
An electrically driven coolant pump supplies indirect charge-air cooling fully flexibly and on-demand in the low-temperature circuit and during turbocharger run-on after the engine has been switched off.
Engine cooling through the high-temperature circuit is via the thermostat casing with an integrated water pump driven via the exhaust camshaft by a zero-maintenance toothed belt.
