DOI : Background: The application of centrifugal pumps is found in domestic and petrochemical industries. Industrial centrifugal pumps are designed and tested using water as working fluid before supplied to industries, as water is commonly available. However, centrifugal pumps are used in industries for various applications, which involve the handling of fluids other than water- like saline-water, crude oil, gasoline, etc. Consequently, hydraulic performance of the pump differs from the designed and tested values and pump performance becomes unpredictable. Cavitation characteristics of the pump handling different fluids other than water are also changed and many a time, cavitation starts prematurely. As a result, the operating cost of pump is increased.

Turbomachinery Design and Theory

Patented Jan. Church, Mount Vernon, N. As heretofore constructed, a centrifugal pump is primarily a constant pressure, variable volume machine when driven at constant speed. When motor drive. A serious problem occurs when under certain conditions variable pressure is required from such a pump. The pump has usually been designed for the maximum pressure and all pressures below maximum were obtained by throttling, at a large sacrifice in power, that is, the friction loss due to throttling represents power.
