What is a Centrifugal Pump?

What is a centrifugal pump? Centrifugal pumps are a popular choice for low viscosity (thin) liquids that need to be pumped at high flow rates. Centrifugal pumps are often used in many industrial, municipal and commercial applications and are usually quick to install and easy to repair. Centrifugal pumps use one or more impellers that rotate on a shaft.

The rotating impeller moves the fluid along the spinning vanes, which increases the velocity of the fluid. The fluid then leaves the impeller vanes and moves into the pump volute where the velocity of the fluid is converted into high pressure through a diffusion process. Then the fluid is sent through the discharge port of the centrifugal pump and into the piping system.

There are dozens of centrifugal pump types available, including: end suction pumps, booster pumps, regenerative turbine pumps, fire pumps, grinder pumps, jet pumps, mag drive pumps, submersible pumps, trash pumps and many more.
