    2009-3-31 · The pump produces approximately 6 GPM (22.7 LPM) at 1,800 RPM and atpressures up to “A” [its low pressure setting], while consuming roughly“C” [horsepower (kW)]. When the load resistance increases the operatingpressure above “A,” the unloading valve will automatically reduce outlet flowby approximately 75%, thus limiting the overall horsepower required.
