Abstract: The sediment concentration is very high in many rivers in the world, especially in
China. The pumps that designed for the clear water are usually seriously abraded. The probability
of pump cavitation is greatly enhanced due to the existence of sand. Under the joint action and
mutual promotion of sand erosion and cavitation, serious abrasion could occurred, and the
hydraulic performance of the pump may be greatly descended, meanwhile the safety and
stability of the whole pump are greatly threatened. Therefore, it is significant to investigate the
cavitation characteristic of pump under sediment flow condition. In this paper, the flow in a
single stage centrifugal pump under cleat water and sediment flow conditions was numerically
simulated. The cavitation performance under clear water was firstly analyzed. Then, The pressure,
velocity and solid particle distribution in centrifugal pump under different particle diameter and
different particle concentration was investigated by using the two-fluid model; The area and
