Abstract
A screw centrifugal pump is a non-clog type pump known as the sewage pump to transfer solids such as rags, hair, clusters of stringy material, and digested sludge applications. With the large and open channel from suction to discharge, the screw centrifugal pump shows better solids transferring capability, even the sensitive products such as food (tomato, potato), live fish, eel, shrimp. However, the impeller blade inlet of screw centrifugal pump with the high rotation speed can damage the live fish or food. Therefore, in this study, the impeller blade inlet shapes are investigated for their influence on the performance of the live fish transfer pump. The straight, concave, and convex blade inlet shapes are created. Numerical analysis was conducted to study the pump hydraulic and suction performances according to the impeller blade inlet shapes of the screw centrifugal pump.
