Abstract In order to develop a CFD-based method for predicting hydraulic performance of multistage centrifugal pump, a multistage centrifugal pump is selected as the study object, and the information of flow field in the whole pump is obtained as well. Specially, the three-dimensional flow domain models of single-, two- and three-stage for the pump are generated and the hydraulic loss across each through-flow component in every stage in those models is obtained. It is shown that the hydraulic loss across a through-flow component in the single-stage model is basically similar to that across the counterpart in the two- or three-stage model, implying the loss is independent of the number of stages chosen and a model with less number of stages can be used to predict performance of a multistage centrifugal pump. By analyzing the energy loss in the models of multistage centrifugal pump to demonstrate the loss characteristics and flow features in each stage, it is found that the vortex structure is nearly consistent across every stage except the diffuser in the last stage. By making use of energy analysis combined with vortex dynamics approach, a set of formulas for predicting the performance of multistage centrifugal pump are established according to a computational model with a few stages. 
