In the present study a cast iron pulley operated centrifugal pump was selected which has 11 components namely casing, impeller, shaft, pulley, bearing stand, bearing cover, top flange, bottom flange, gland, counter weight and base. It was found that the present existing centrifugal pumps have many technical disadvantage related to its cost, weight, corrosion and wear and tear. During the study it was found that these technical disadvantages can be overcome by replacing the metallic parts of pumps with the engineering plastic materials.

The experiment results reveal suitability of using a mono block centrifugal pump in hydro turbine mode. The results confirm that the pump in hydro turbine mode operate at higher heads and discharge as compared to the pump mode operation. BEP (best efficiency point) for the pump in hydro turbine mode is lower than in pump mode operation. Correlations proposed by earlier researchers for performance prediction of pump in hydro turbine mode are also tested.

In the Department of Structural and Fluid Mechanics we are happy to present the first English edition of the book: ’The Centrifugal Pump’. We have written the book because we want to share our knowledge of pump hydraulics, pump design and the basic pump terms which we use in our daily work. ’The Centrifugal Pump’ is primarily meant as an internal book and is aimed at technicians who work with development and construction of pump components.
