There are three general categories that centrifugal pumps fall into: mixed flow, axial flow, and radial flow. Axial flow centrifugal pumps are centrifugal pumps that use the direct action of the impeller on the liquid to develop pressure. Radial centrifugal pumps are centrifugal pumps that completely use centrifugal force to develop pressure. Mixed centrifugal pumps are centrifugal pumps that use both centrifugal force and the action of the impeller on the liquid to develop pressure.

Centrifugal pumps can use many sources for a power supply, including AC power, DC power, natural gas, steam, water, gasoline, and solar power. Some centrifugal pumps, when purchased, do not include a power source. Instead, they only include the pump mechanism, and either a drive shaft or another mechanical device that later connects to a power source.

Many different industries employ centrifugal pumps for varied uses according to the industry. For example: cryogenics use centrifugal pumps in extreme cold applications; dairy farmers use centrifugal pumps to keep their product at the proper temperatures, hot and cold; electric utility companies use centrifugal pumps, or turbines, to produce energy; food service, construction, distillery, and automotive companies are a few more examples of industries that employee centrifugal pumps for their many applications.

There are many types of centrifugal pumps that allow for individualized ease of application. Ballast and bilge centrifugal pumps can be found aboard almost any ship or vessel hard at work removing or loading water into or out of the bilge or ballast. Drum centrifugal pumps are generally used to transport the contents of drums, barrels, or tanks. Grinder centrifugal pumps are used in sewer systems to grind refuge and sewage, then raise the sewage to a higher elevation. Magnetic drive centrifugal pumps are generally used in laboratories, chemical processing, OEM applications, and production lines.

Centrifugal pumps are used in nearly ever industry available today. Keeping the centrifugal pump well-maintained will prolong its life and add quality and to its functionality.
