Centrifugal pumps rely on the principal of centrifugal force

- Oct 26, 2017 -

Centrifugal pumps rely on the principal of centrifugal force. The centrifugal force usually affects an object or material that is moving in a circular pattern causing it to move away from its central axis or center point of path along which it is rotating. This force can be utilized in machines to regulate the pressure and motion within a pumping unit, and then combined with other centrifugal pumping principals to form the working nature of hydraulic mechanisms.

the centrifugal pump is based around a casing that is filled with fluid which is usually water. The special casing inside forces a fast rotary motion that causes the water to spin. This would generate the centrifugal force and to eventually channel it through the discharge point. The discharged water is then responsible for creating a vacuum for atmospheric pressure and thereby forcing more water out of the casing. This is a continuous process, which is dependent mostly on the rotary motion of the casing and the constant supply of water.

It works very simply just like a centrifuge. Spinning any fluid quickly will force it outward from the center of rotation. This creates a pressure differential between the center and outside of the enclosure. By putting the inlet at the center and the outlet near the edge the fluid will flow through the pump as it turns.
