How Does a Centrifugal Pump Work?
A centrifugal pump is a type of rotary pump that uses centrifugal force to move fluids. It works by accelerating the fluid inside a spinning impeller, which creates a vacuum at the inlet of the pump. This vacuum draws in fluid from the inlet, and the impeller then propels the fluid outward into a discharge pipe. The centrifugal force generated by the spinning impeller causes the fluid to travel outwards in a circular motion, creating pressure in the discharge pipe. This pressure is then used to move the fluid through the discharge pipe, allowing it to be pumped to its destination. Centrifugal pumps are commonly used in a variety of applications, including water supply systems, agriculture, and manufacturing.
