The application for mixed flow pumps is in the range of 3 to 30 meters head and is characterised with a fairly constant efficiency with varying heads. Centrifugal pumps are used when high heads are re- quired (above 20 meters). With serial or multi stage pumping heads up to 1000 meter can be reached.

Centrifugal pumps are generally sized to operate at or near the best efficiency point at maximum flow. The maximum flow requirements, however, frequently occur for a very short period during the operating cycle with the result that some method of flow control is required.

Typical centrifugal pumps will show an increased flow rate as head pressure decreases. The curve also shows the shut off head or the head that the pump would generate if operating against a closed valve. In our same example, the shutoff for the 7.9” impeller is 45 ft of head. The pump performance curve also provides efficiency curves.
