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
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 ap-
proximately 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 0.00455.To find specific
outputs at various RPM, use the formula:
GPM = 0.00455 x RPM
RPM GPM 2000 PSI 2500 PSI 3000 PSI 3625 PSI
