Overall pump efficiency
WebApr 25, 2016 · Anderson: To convert horsepower to kW we must do the following equation: (gpm x TDH x S.G.) / (3,960 x pump efficiency x motor efficiency x VFD efficiency) x 0.746. This will convert EHP or electrical horsepower to kW. I would recommend always sizing a generator to the maximum load of the motor.
