Fully Variable (ECF) Water Pump

Fully variable water pump ECF

The professional in demand recognition

In addition to switching the coolant flow on and off this fully variable ECF (Electro hydraulically Controlled Flow) - water pump can regulate the flow rate in between with a modulated hydraulic pressure generated by an electrically initiated and pulsing solenoid valve. For completing the control loop NGPM uses a constant feedback of the control slider’s position by magnet and sensor.

This concept supports NGPMs main goal to reduce the CO2-emissons due to a coolant flow perfectly adjusted to the engine’s demand.

Special features

On demand coolant heat management / flow regulatioN
Fast engine heating causes a reduction of fuel consumption and emissions
Independent from vacuum
In comparison to constant pump no increase of installation space
Power reserves of Axial Piston Pump when controlling
Fail-safe function: a full delivery is guaranteed even if there is a control failure
