A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller’s vane tips.
How Centrifugal Pumps Work?
Centrifugal pumps are a type of pump that uses centrifugal force to move liquids or gases from one place to another. They are used in many industries, from water treatment to oil extraction, and are one of the most common types of pumps used in the world today.
The basic principle of a centrifugal pump is simple: a rotating impeller creates centrifugal force which causes liquid or gas to move from the inlet to the outlet of the pump.
The impeller is the part of the pump that spins and creates the centrifugal force. It consists of a number of curved blades that rotate around a central axis.
As the impeller spins, the blades create a pressure differential between the inlet and outlet of the pump. Incoming liquid or gas is forced outward by the centrifugal force, creating a pressure drop at the inlet.
This pressure drop drives the liquid or gas out of the outlet. Centrifugal pumps can be divided into two main types: single stage and multi–stage.
In a single stage pump, the impeller is the only component that spins. In a multi–stage pump, the impeller is followed by additional stages of impellers, each increasing the pressure of the liquid or gas as it passes
