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 5 Specifications Model P220A U.S...............................Metric Flow.....................................................................4.7 GPM......................17.8 LPM Pressure (Continuous).......................................2000 PSI......................140 Bar Pressure (Intermittent) .......................................2500 PSI......................175 Bar Maximum Crankshaft Speed ................................................................... 1750 RPM Maximum Inlet Pressure....................................145 PSI........................10 bar Plunger Diameter...............................................0.71”............................18 mm Stroke..................................................................0.56”............................14.1 mm Max.

I 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.
