PUMP SELECTION, SIZING AND INTERPRETATION OF PERFORMANCE 4 • 3 Performance Curve At some point in the pump selection process, the impeller diameter is selected.
Centrifugal pump Pump Curves ... typically plot a separate pump curve for each size of impellor on the same pump performance chart. Smaller impellors produce less pressure at lower flow rates. Pump performance charts with multiple pump curves are shown below.
