Pump School Lesson 2 The Pump Curve (PPCO)

To control the flow of a centrifugal pump it is normally necessary to restrict the discharge pipeline, usually with a valve, and thus set the flow at the desired rate. a 7 1/2 hp motor would adequately power the pump at a duty point of 120 gpm at 150 feet. But notice that the end of curve brake horsepower requires that a 10 hp motor be used.
