The ratings shown are the power requirements for the pump. Gas engine power outputs must be approximately twice the pump power requirements shown above.
We recommend a 1.15 service factor be specified when selecting an electric motor as the power source. To compute specific pump horsepower requirements use the following formulas:
Electric HP = (GPM X PSI)/1450
Gas HP = (GPM X PSI)/1100
*Engine power varies based on horizontal or vertical orientation, as well as by makes and models from each manufacturer.
