This animated video is aimed at giving a logical explanation on the working of centrifugal pumps. The importance of priming, cavitation & NPSH and commonly used impeller types are also illustrated in this video. Centrifugal pumps are the most preferred home water pumps. Depending upon the fluid viscosity different impeller types such as open, semi-open and shrouded are used. Mechanical design aspects of centrifugal pump such as water sealing arrangement and bearing housing are also well explained here.
