Centrifugal pumps are the most preferred hydraulic pumps that are mainly used for pumping water in industrial and residential properties.
A Centrifugal pump works on the principle that a fluid of mass is given a force it is thrown outward radially.
The main parts of the centrifugal pump include - Suction eye, Vanes, Impeller, Casing, Suction pipe, and Discharge pipe.
The impeller rotates to create a pressure drop in the suction side. The types of the impeller are - Open impeller, Closed impeller, and Semi-closed impeller.
At the heart of the system lies impeller. It has a series of curved vanes fitted inside the shroud plates. The impeller is always immersed in the water. When the impeller is made to rotate, it makes the fluid surrounding it also rotates. This imparts centrifugal force to the water particles, and water moves radially out. Since the rotational mechanical energy is transferred to the fluid, at the discharge side of the impeller, both the pressure and kinetic energy of the water will rise. At the suction side, water is getting displaced, so a negative pressure will be induced at the eye. Such a low pressure helps to suck fresh water stream into the system again, and this process continues.
