Functions of Electronic Water Pump
GMB electric water pump is installed into HEV, EV or FCV in order to cool down the surrounding devices of these vehicles. Conventional mechanical water pump is powered by combustion engine to circulate coolant around the engine. Volume of coolant is in proportion to the engine revolution. Just control of coolant volume on demand is not mechanically possible. It may either overcool or undercool.
Electric water pump is activated by battery and motor only on demand for cooling. The just function minimizes the load on engine.
* Our electric water pump HCC-20 of 20W series which we are producing in a good volume, to the contrary, functions as auxiliary heater. HCC-20 circulates the heated liquid into the heating device when engine stalls.
