How Centrifugal Pumps Work

Before starting the pump, fill the pump and the inlet pipe with water. After the pump is running, the water in the impeller flow channel is thrown around by the centrifugal force generated by the high-speed rotation of the impeller. The water in the pool is sucked up along the suction pipe under external atmospheric pressure to supplement this space. The inhaled water is then thrown out by the impeller through the volute and into the outlet pipe. It can be seen that if the impeller of the centrifugal pump rotates continuously, it can continuously absorb and pressurize water, and the water can be continuously raised from a low place to a high place or a distance. In summary, the centrifugal pump is called a centrifugal pump because it lifts water to a high place under the action of centrifugal force generated by the high-speed rotation of the impeller.
