Structure composition and working principle of gravel pump

The gravel pump is mainly composed of a pump body, impeller, shaft, bearings, and sealing device. The pump body is made of wear-resistant materials to adapt to media containing solid particles; The impeller is the core component responsible for introducing the medium from the suction port and pushing it to the discharge port; The shaft and bearings support and drive the impeller to rotate; The sealing device ensures that the medium inside the pump body does not leak. Its working principle is based on centrifugal force. By rotating the impeller, liquid and solid particles are thrown towards the edge of the pump casing to form a high-pressure zone, thereby achieving medium transport.
