It is important in pump design that the axial thrust of a mixed-flow pump is predicted with accuracy. Predictions of the axial thrust were carried out with CFD for mixed-flow pumps of three specific speeds. The region concerning with the axial thrust prediction was taken out, and was divided into two parts. One of them was the hydraulic part, which included the impeller and the vaned diffuser. The other was the rear part of impeller. Those parts were calculated individually. The CFD results were compared with experimental ones. They showed good agreements. It is shown that the axial thrust for a mixed-flow pump can be predicted using CFD with practical accuracy.
