Specifications
Model P319
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.
NOTE:
1 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 require-
ments 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
SPECIAL NOTE:
The theoretical gallons per revolution
(gal/rev) is 0.0014.
To find specific outputs at various RPM,
use the formula: GPM = 0.0014 x RPM
