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.
NOTES:
In order to drive the pump from the side opposite the present shaft exten-
sion, simply remove the valve casing from the crankcase and rotate the
pumps 180 degrees to the desired position. Be certain to rotate the seal
case (item #20) as well, so that the weep holes are down at the six o'clock
position. Exchange the oil fill and the oil drain plugs, also. Refer to the
repair instructions as necessary for the proper assembly sequence.
HORSEPOWER RATINGS:
The rating shown are the power re-
quirements 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 elec -
tric motor as the power source. To
compute specific pump horsepower
requirements, use the following for-
mula:
HP = (GPM X PSI) / 1450
SPECIAL NOTE:
The theoretical gallons per revolution
(gal/rev) is 0.00455.To find specific
outputs at various RPM, use the formula:
GPM = 0.00455 x RPM
