Abstract
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. Authors have been proposing 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 internal flow in this single blade sewage pump impeller by LDV measurement and CFD. As a result of having examined influence of impeller blade loading and volute casing, it clearly indicated the following facts. As well as influence of impeller blade middle loading and influence of the secondary flow, by increase of slip by influence of volute casing, static pressure and total pressure suddenly decrease together towards the end from impeller blade middle neighborhood.
