While working these pumps are more subjected to the wear and consumes more power. Hence single stage end suction radial flow pumps are used for these applications. The pump performance is mainly depends on the vane shape, impeller and volute and as well as the supporting mechanical parts. Hence, design has been concentrated on the flow path of the fluid through the vanes and volute section. Since energy is transmitted to the fluid through vanes, so vane shape plays a very important role in effective energy transfer. The impeller and volute is been designed by Walter K Jekat method and Error triangle method given by Stepanoff A J., which is modified during this work by taking equal divisions and varying vane inlet angle form hub to shroud is used to generate the vane which has given an improved efficiency with reduced power consumption with compact design. The model prepared is been analyzed in CFD tool CF Design 2010 and its performance is analyzed at different flow rates. Major work is concentrated on vane shape. * Design Engineer, Weir Minerals India Private Limited, Bangalore. ** Assistant Professor, Department of Mechanical Engineering, Siddaganga Institute of Technology, Tumkur, Karnataka. *** Manager Technical, Weir Minerals India Private Limited, Bangalore.
