Sewage pumps are designed with a wide flow channel by, for example, sacrificing some efficiency and reducing the number of blades, in order to prevent plugging with foreign bodies. This paper proposes a new type of sewage pump impeller designed to further improve pump efficiency and performance in passing foreign bodies. This sewage pump impeller has a structure in which the suction flow channel of closed type non-clog pump is wound in a helical spiral. The focus of this research was to investigate pump performance, internal flow and radial thrust in this single blade sewage pump impeller. The results clearly indicated the following facts. The developed sewage pump impeller had high efficiency and exhibited high efficiency over a wide range of flow rates. Internal flow of this pump is very complicated, and a state of internal flow largely changes when flow rate changes, and force which is non-uniform in the circumferential direction is applied to the impeller.
