The working principle of a centrifugal pump

2025-06-09

Centrifugal pumps rely on the high-speed rotation of the impeller to throw the liquid from the center of the impeller to the edge under the action of centrifugal force, thus gaining kinetic energy and pressure energy. After entering the pump casing, the liquid flows through a gradually expanding channel, converting part of its kinetic energy into static pressure energy, and finally being discharged from the outlet. At the same time, a low-pressure area is formed in the center of the impeller, and the external liquid is sucked in under the action of atmospheric pressure, forming continuous delivery.
