Centrifugal pump is a type of turbomachinery which is dynamically axisymmetric and work absorbing in nature. In more simpler terms it’s a pump which is used to lift liquids from a lower area to a higher area. Its most widely used in industries where sensitive fluids as in chemical industries are required to be moved.
The basic principle of centrifugal pumps is the conversion of rotational kinetic energy to hydrodynamic energy of fluid movement. The fluid enters through the pump impeller near the rotating axis and gets accelerated reaching the desired destination.

It is the heart and soul of a centrifugal pump it has following subtypes.
This impeller does not have a crown and base plate, it finds wide application where physical impurities in the liquid to be pumped has to be kept at bay.
It is completely covered with no scope of any foreign body entering. Widely used for pumping water.
Lacks a crown plate and is suited for fluids which might have charged debris in them.
