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.
NOTES: 1 Positive inlet pressures are recommended!
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:
HP = (GPM X PSI) / 1400
