Specifications
Model GP8055
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
requirements for the pump. Gas
engine power outputs must be
approximately twice the pump
power requirements shown above.
We recommend a 1.1 service factor
be specified when selecting an
electric motor as the power source.
To compute specific pump horse
power requirements, use the
following formula:
GPM X PSI
SPECIAL NOTE:
The theoretical gallons per revolution (gal/rev) is 0.130.
To find specific outputs at various RPM, use the formula:
GPM = 0.130 x RPM
= HP
