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:

In order to drive the pump from the side opposite the present shaft extension, simply remove the valve casing from the crank- case 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.

P221A HORSEPOWER REQUIREMENTS

RPM GPM 1000 PSI 1500 PSI 2000 PSI* 2320 PSI*

1150	1.4	1.0	1.5	2.0	2.3
1450	1.8	1.3	1.9	2.5	2.9
1750	2.2	1.5	2.3	3.0	3.5

*Intermittent duty only

SPECIAL NOTE:

The theoretical gallons per revolution (gal/rev) is 0.00126.

To find specific outputs at various RPM, use the formula: GPM = 0.00126 x RPM

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
