Abstract: Experimental work involving the modification of an impeller with straight front shroud to curved one to satisfy the condition of uniform variation of velocities in the vane channel is attempted. Inspection of vanes and vane channels using precise and accurate instrument will form an important step in the manufacture and realization of an impeller. A method of such inspection procedure for vanes and vane channels is presented. The values of linear correlation coefficient of vanes and vane channels are used for evaluating the variations from one channel to another. Performance and cavitation characteristics of the pumps have been obtained experimentally at various discharges and speeds of nine bladed single stage centrifugal pump of shape number 95 using straight and curved front shrouded impellers. The results for two impellers have been compared.
