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 SPECIAL NOTE: The theoretical gallons per revolution (gal/rev) is 0.0009855. To find specific outputs at various RPM, use the formula: GPM =0.0009855xRPM P21 7A H ORSEPOWER REQUIREMENTS RPM GPM 1000 PSI 1500 PSI 2000 PSI 2500 PSI* 1725 1.7 1.2 1.8 2.4 3.0 3000 3.0 2.1 3.1 4.2 5.2 3200 3.2 2.2 3.3 4.4 5.5 3450 3.4 2.3 3.5 4.7 5.9 *Pressure washer duty only 3 Specifications Model P218A Volume...................................................................................................Up to 3.4 GPM Discharge Pressure................................................................................Up to 2500 PSI* Inlet Pressure.........................................................................................Up to 90 PSI RPM......................................................................................................Up to 1750 RPM Plunger Diameter.................................................................................... 18mm Stroke..................................................................................................... 10.0mm Temperature of Pumped Fluids...............................................................Up to 160oF Inlet Ports...............................................................................................(2) 1/2" BSP Discharge Ports......................................................................................(2) 3/8" BSP Shaft Rotation.............................................................................Top of Pulley Towards Fluid End Crankshaft Diameter .............................................................................. 24mm Key Width..............................................................................................8mm Shaft Mounting.......................................................................................Right Side Facing Manifold Weight.................................................................................................... 11 lbs. 11oz.

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.
