The sewage pump are demanded a high pump efficiency and a performance in passing foreign bodies. Therefore, the impeller used by these usages demands the large passing particle size (minimum particle size in the pump). However, because conventional design method of pump impeller calculates impeller exit width small, it is difficult to apply to single-blade centrifugal pump impeller which is used as a sewage pump. This paper proposes design method for single-blade centrifugal pump impeller. As a result, the head curve of the impeller by this design method satisfied a design point, and pump efficiency was over 62% more than conventional single-blade centrifugal pump impeller. Having compared design values and CFD analysis values, the suction velocity ratio of the design parameter accorded well, but the relative velocity ratio did not agree by the influence of the backflow of the impeller entrance.
