HORSEPOWER RATINGS:
The rating 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 1.1 service factor be specified when selecting an electric motor as the power source.
To compute specific pump horsepower requirements, use the following formula:
GPM X PSI = hp 1400
