Just What is a Centrifugal Water Pump?

We have some pretty intelligent customers, but others are not exactly engineers. This is why they call on us for pump sales, service and repair. But we always like it when our customers have a basic knowledge of what we do. It makes conversations a little easier. With that said, today we’d like to take a minute to define exactly what a centrifugal water pump is.

By definition, centrifugal water pumps transport fluids using rotational energy, typically powered by a motor. The fluid is accelerated by the impeller – a series of curved or triangular plates that are always immersed in fluid – which is housed by a casing. Depending on the type of fluid being moved, the impeller may be closed, semi-open or open. Liquid flows into the suction port and he impeller moves the water radially outward to the discharge nozzle. This velocity is converted to pressure energy.

Common applications of centrifugal water pumps are industrial, agriculture, municipal water and wastewater plants, power generation plants, petroleum and many other industries.

One of the best ways to learn how a centrifugal pump works is by seeing it for yourself. Check out this short 5 minute video which we think offers a great explanation.
