What is the maximum practical lift of a centrifugal pump?

The maximum practical lift of a centrifugal pump is typically in the range of 15 to 25 feet. This range is acknowledged due to the fundamental operating principles of centrifugal pumps, which experience limitations in their ability to create suction lift.

In practice, centrifugal pumps rely on atmospheric pressure to push water into the pump through an inlet. The maximum amount of lift they can provide is influenced by factors such as the design of the pump and the desired flow rate. As the lift increases, the efficiency and performance of the pump can decrease significantly due to issues like cavitation and lower flow rates. This makes the 15 to 25 feet range a practical maximum where pumps can operate effectively while still maintaining a reasonable flow rate.

Choosing values outside this range could lead to operational challenges, inefficiencies, or potential equipment damage, reinforcing why the specified maximum lift is recognized.
