Performance of a Centrifugal Pump with Variation of Impeller Speed

Abstract

This research is addressed to investigate the characteristics of a centrifugal pump. In this work, the experiments were carried out with variations in impeller speed and at several valve openings. The measurement results show that head have the same tendency for all variations of inlet valve opening. Meanwhile for discharge and break horse power have almost the same values ​​at low speed for both theoretical and measurement; however at higher speed there is a significant difference. Large inlet valve openings produce large discharges as well as break horse power and motor horse power. Meanwhile for the head, the inlet valve opening has no crucial effect because it produces almost the same value.
