Abstract:
Abstract: The aim of this study was to experimentally investigate the effect of speed, concentration and size of
slurry on the performance of a centrifugal pump. For this purpose a facility was built where the performance of a
centrifugal slurry pump was examined using aggregate slurry. Three sizes of slurry with three concentrations and at
three impeller speeds were used for the performance investigations of a centrifugal slurry pump. As a reference
performance the performance of centrifugal slurry pump was also tested with clean water. The performance of pump
has been reported as variations of head, power and efficiency at various flow rates along with the system
characteristics of the pump. The results reveal that the pump performance is grossly affected by the type of slurry, its
concentration and size. Besides this the variation in speed also affects the performance as is observed in pumps with
water. The maximum decrease in the head, with respect to clear water, at the operating point was found to be 47%
for aggregate for size 20 mm, 15% concentration and 2600 rpm. The maximum decrement in efficiency at operating
point for aggregate was found to be 47% for 4 mm size, 15% concentration and at 2200 rpm. The power increment
requirement for aggregate was 9% for 4 mm size, 15% concentration and 2600 rpm.
