HORSEPOWER RATINGS:
The rating shown are the power re-
quirements for the pump. Gas e n g i n e
power outputs must be a p p r o x i m a t e l y
twice the pump
power requirements
shown above.
SPECIAL NOTE:
F
OR
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
