The end suction centrifugal pump is mainly composed of pump body, impeller, shaft, bearing, sealing device and other components. The pump body is usually made of cast iron or stainless steel material and has good corrosion resistance. The working principle is based on the action of centrifugal force. When the motor is started, power is transmitted to the pump shaft through a transmission device to make it rotate. The impeller then rotates, generating centrifugal force. Under the action of centrifugal force, the liquid enters the pump body from the inlet and is pushed by the impeller to the outlet. At the same time that the liquid is pushed out, the pump body will form a low pressure area, so that the inlet produces negative pressure, so that the liquid is sucked into the pump body. In this way, the end suction centrifugal pump can achieve uninterrupted transfer of liquid out.
