Abstract

The present experimental study deals with the effect of varying different soft slurry concentrations ranging from 0 to 18 % by weight on the performance characteristic of a centrifugal pump. Experimental results are presented for pump performance (head, overall efficiency and electrical power input) as a function of the flow rate. In addition the pump performance is predicted by general empirical correlations, using the obtained experimental data as function of the soft slurry concentration used in the present study. Within the operating range of the considered parameters, the obtained results show that the head and the efficiency of a centrifugal pump with soft slurry are lower in comparison to water due to the presence of soft slurry. The head and the efficiency of a centrifugal pump decrease with increase in slurry concentration by weight and specific gravity. Power consumption on the other hand increases with the increase in soft slurry concentrations and specific gravity.
