A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid, and are commonly used to move liquids through a piping system. When the fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system.
Centrifugal pumps are used for large discharge through smaller heads.
Different Types Of Centrifugal Pumps
Multistage pumps have multiple impellers, which increases the discharge pressure.
A sealess centrifugal pump, where the impeller is not attached directly to the motor, instead the impeller is attached to magnets, and opposing magnets force the impeller to rotate.

A grinder pump is fitted with teeth that designed to grind and chop solids.
Circulator pumps are designed to circulate fluids or gases in a closed system.
Canned Motor Pumps
A canned motor pump is a sealess centrifugal pump, with the impeller attached to the motor rot, and the wetted parts inside a can.
A slurry centrifugal pump is a heavier and more robust version, and are designed to handle slurry.
Trash pumps are toughened and are designed to pump water solid particles.
Cryogenic pumps, as the name suggest are designed specifically to handle low temperatures.
