HORSEPOWER RATINGS:
The rating shown are the power re-
quirements for the
pump. Gas engine
power outputs must be approximately
twice the pump power requirements
shown above.
SPECIAL NOTE:
FOR CONTINUAL OPERATION, THE SPEED
OF
THE PUMP MUST BE LIMITED TO 700
RPM, AND THE MAXIMUM PRESSURE OF THE
PUMP
MUST BE REDUCED BY 10%.
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.
We recommend a 1.15 service fac-
tor be specified when select-
ing an electric motor as the
power source. To compute
specific pump horsepower
requirements, use the follow-
ing formula:
HP = (GPM X PSI) / 1450
