Specifications
Models GP8055 / GP8055-1000
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 1.15 service
factor be specified when select-
ing an electric motor as the power
source. To compute specific pump
horsepower requirements, use the
following formula:
SPECIAL NOTE:
The theoretical gallons per revolution (gal/
rev) is 0.130. To find specific outputs at vari-
ous RPM, use the formula:
GPM = 0.130 x RPM
GPM x PSI = HP
