NOTE:
In order to drive the pump from the side opposite the present shaft extension, 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.

Specifications
Model P227
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 specific pump horse
power requirements, use the
following formula:
HP = (GPM X PSI) / 1450
