Centrifugal pump drives the impeller to rotate through the pump shaft to generate centrifugal force. Under the centrifugal force, the liquid is thrown to the impeller exit along the flow path of the impeller, and the liquid is collected by the volute and sent to the discharge port. The liquid takes energy from the impeller, increases both pressure energy and kinetic energy, and relies on this energy to deliver the liquid to the work site. While the liquid is being thrown to the exit of the impeller, a low pressure is also formed at the center of the entrance of the impeller, resulting in a pressure difference between the liquid at the center of the suction tank and the impeller. Due to the pressure difference of the liquid in the suction tank, Continuously through the suction pipe and pump suction chamber into the impeller.
