In this paper, the mechanism of back flow to the suction side of mixed-flow pump impeller was studied by measuring the pressure distribution and the flow direction on the outside of impeller blades. Furthermore, the effect of setting angle of impeller blades on the back flow mechanism was investigated. The obtained results are mainly as follows : (1) The pump performance was made clear. (2) Pressure distributions and flow patterns on the outside of impeller blades were made clear. (3) The difference of flow on the outsides of axial-flow and mixed-flow impellers was made clear. (4) Two different reasons for the beginning of the back flow were discovered with the mixed-flow impeller.
