Before the pump starts, the pump and the inlet pipe are filled with water. After the pump runs, under the action of centrifugal force generated by high-speed rotation of the impeller, the water in the impeller runner is thrown around and pressed into the volute. The inlet of the impeller forms a vacuum, and the water in the pool is sucked into the suction pipe under the external atmospheric pressure. Then the suction of the water is thrown out by the impeller through the volute and into the outlet pipe. It can be seen that if the centrifugal pump impeller constantly rotating, it can continuously absorb water, pressure water, water can continuously from low to high or far away. To sum up, the centrifugal pump is due to the centrifugal force produced by the high-speed rotation of the impeller under the action of the water to the height, so called centrifugal pump.
