Flow in the Low Specific Speed Centrifugal Pump with Circular Casing
Access this Article
The internal flow of a centrifugal pump with semi-open impeller, whose type-number is O.244, is measured by PIV method and analyzed numerically The head and efficiency of a pump that has a circular casing with a very small radius are almost same as those of the spiral casing. Even at the best efficiency point, the internal flow in the pump of circular casing is asymmetric. The flow goes out from the impeller only at the exhaust area of the casing. Also, there is a very strong unsteady flow near this area.
