What type of pump is a centrifugal pump?

• A. Positive displacement pump
• B. Piston pump
• C. Velocity pump
• D. Reciprocating pump

Answer: (C)

A centrifugal pump is classified as a velocity pump because it operates on the principle of converting kinetic energy into hydraulic energy. In this type of pump, fluid is directed into the impeller, which moves at high speed, creating a centrifugal force that propels the fluid outwards through the pump's volute or diffuser. The increase in the fluid's velocity translates into pressure as it exits the pump. This classification distinguishes centrifugal pumps from other types such as positive displacement pumps, which move fluid by trapping a fixed amount and forcing it into the discharge pipe. Centrifugal pumps are commonly used in various applications due to their ability to handle large volumes of fluid efficiently, particularly in water distribution systems. Understanding the operating principles of a centrifugal pump as a velocity-type pump helps in selecting the appropriate pump for specific applications.
