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 1.15 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
1450
Specifications
Consult the factory for special requirements that must be met if the pump is to
operate beyond one or more of the limits specified above.
