Specifications
Model P220A
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.
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
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.
*Intermittent duty only
