What is Centrifugal Pump ?
Centrifugal Pump is a type of rotodynamic pump in which the flow through the pump is induced by the centrifugal force imparted to the liquid by rotation of the impeller.
Parts of The Centrifugal Pump
Rotor : It consist of Impeller And Shaft
Casing : It is the stationary part of the pump which acts as housing to all the internal parts

View of
Centrifugal Pump
Diffuser : The diffuser performs the same function as volute casing i.e convert part of K.E energy of the fluid to the pressure energy.
Eye of the Impeller : In the centre of the impeller, is the eye of the impeller which receives inlet flow of liquid into the vanes of the impeller.
Cavitation
What is
The process of the formation and subsequent collapse of the vapor bubbles in a pump is called cavitation.
What is
Priming
PRIMING is the process in which the pump is filled completely with liquid to be raised from outside source before starting the pump. It is done to remove the air from the pump.
Net Positive Suction Head (NPSH)
Difference between inlet pressure and the lowest pressure level inside the pump.
