Now, the water due to centrifugal force continue to move towards the casing. This drop in pressure creates the suction force of the pump and hence the pump draws the fluid from the suction supply. And because of this movement of the fluid to the outer periphery, there is a drop of pressure at the eye of the impeller. The rotation of the centrifugal pump impeller causes the liquid it contains to move outward from the center to beyond the circumference of the impeller because of the centrifugal effect. DELIVERY PIPEĭelivery pipe is the pipe whose one end is connected to the outlet of the pump and the other end is connected to the required height where water is to be delivered.Īlso Read : Difference Between 2 Stroke and 4 Stroke Engine WORKING OF THE CENTRIFUGAL PUMP The strainer is used to filter the unwanted particles present in the water to prevent the centrifugal pump from blockage. The foot valve is a one way valve that opens in the upward direction so that the water does not flow back to the supply side when the pump is not in the operation. The suction pipe consists of a foot valve and strainer at its lower end. Suction Pipe with Foot Valve And StrainerĪ pipe whose one end is connected with the inlet of the impeller and the other end is dipped into the sump of the water is called suction pipe.
