Performance characteristics of centrifugal slurry pumps

The performance of two centrifugal slurry pumps has been reported for thr e r solid materials having different particle size distribution (PSD) in term s of head, capacity, and power characteristics. The results have shown that the values of head and efficiency ratios are not only dependent on solid c oncentration but are also affected by PSD of the solids and properties of t he slurry. The addition of fine particles in the slurry of coarser material leads to reduction in the additional losses that occur in the pumps due to the presence of solids. It is also observed that with the increase in the pump size, the additional losses due to presence of solids reduce.
