Abstract：The relationship between the wear rates on the surfaces of the impeller as well as volute and the sediment concentration was investigated using the distribution of the wear rates. An Eulerian-Lagrangian computational fluid dynamics(CFD)procedure was used to simulate steady liquid-solid two-phase flow for various pump operating conditions. The FINNIE model was used to predict the abrasion of the surface of impeller and volute. It was found that the relative value of wear rate of impeller and casing surface increased with the increase of sediment concentration; it was larger at the low flow rate of the pump, while the value was lower in the high efficiency condition of the pump. The relative value for the casing surface is larger than that for the impeller surface. The relative value for flow parts is low in the high efficiency area of the pump.
