How Does a Centrifugal Pump Work? | Video

A brief demonstration of how centrifugal pumps work. While it isn't necessary to understand how a pump works, knowing the inner workings of a pump may help to diagnose problems or prevent damage.

Centrifugal pumps are one of the most common pump types. The most important part of a centrifugal pump is the impeller. This impeller rotates inside a casing. Liquid is introduced into the casing while the impeller is spinning, and the impeller throws the liquid through a suction port to the outside of the casing. The fluid, upon exiting the casing, leaves a discharge port. The velocity the liquid receives from the impeller is then converted into "head", or pressure energy.

Centrifugal pumps are favored so heavily because of their higher flowrate compared to most positive displacement pumps. More importantly, flowrate from centrifugal pumps can be throttled easily with a valve placed into the discharge piping with little pressure buildup. This flexibility allows centrifugal pumps to be used for a variety of pumping applications.
