Specifications
Model GP8065 / GP8065-1000
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
selecting an electric motor as the
power source. To compute spe
-
cific pump horsepower require-
ments, use the following formula:
GPM X PSI
= HP
1450
SPECIAL NOTE:
The theoretical gallons per revolution (gal/
rev) is 0.182. To find specific outputs at vari-
ous RPM, use the formula:
GPM = 0.182 x RPM
