* Do not exceed 94 BHP (70 kW).
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.
HORSEPOWER RATINGS:
The rating shown are the power require-
ments 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
SPECIAL NOTE:
The theoretical gallons per revolution (gal/rev) is
0.068.
To find specific outputs at various RPM, use the
formula:
GPM = 0.068 x RPM
