Hydraulics in their best form
The Switchable ECF (Electro hydraulically Controlled Flow) Water Pump is based on a hydraulic control of the internal control unit. This one is working on the on-/off-principle. When the water pump is in the deenergised state ("on"), the coolant flow is unhindered transported from the spiral channel into the engine block of the internal combustion engine.
- In the energised state ("off") the magnet valve is triggered and this causes that the internal hydraulic circuit is closed. Thereafter it builds up a pressure and the control slide moves mechanically through the impeller. This results in an interruption of the coolant flow rate ("standing water"). The return of the control slide in the deenergised state is saved by a return spring.
