Centrifugal pumps comprise of a high-speed rotating impeller to which vanes are fixed. This impeller helps to move the liquid from one end to another. A tight casing envelops the impeller which has a delivery pipe on one of its sides. These robust centrifugal pumps transfer primer mover's energy into kinetic energy and later into pressure energy of the fluid.

Though, for economical and trouble-free handling of solid-laden liquids, industries today prefer self priming centrifugal pumps. A self priming pump has a large volute that facilitates automatic re-priming without requiring suction and discharge check valves. It operates without any external support by creating and maintaining an adequate vacuum.

In recent times, however, environmental concerns and frequent problems of mechanical seals have given rise to sealless pumps. The sealless pumps have witnessed a meteoric growth in past decade and owing to the developments in its manufacturing processes, their application is rapidly expanding. This has resulted in advanced improvements in the operational safety and consistence performance.
