PARAMETRIC INVESTIGATION OF A CENTRIFUGAL SLURRY PUMP WHILE HANDLING CLEAR WATER

Abstract

The results show that the increase in blade number leads to an increase at head and shaft power. However, the hydraulic efficiency is variable and depends on flow rates. Around operation conditions of the studied pump, the impellers which have three and four blades are more efficient than impellers with two and five blades. Furthermore, by increasing of blade height from 30 mm to 50 mm, the performance of the slurry pump increases only at high flow rates. On the other hand with the decreases in blade thickness from 50 mm to 30 mm, the performance of centrifugal slurry pump increases at all flow range.
