Impeller is the most important wet-end spare part of a slurry pump. Centrifugal pumps need impellers to produce the centrifugal force which transfers the slurries. The centrifugal force is produced by the impeller which rotates to a certain speed. The max. tip speed of an impeller should be limited within 55m/s. 

At CNSME, various impellers are available to choose for the same model of slurry pumps, for example, for pump 8/6E-AH, we have the standard 5-vane closed impeller, as well as the 6-vane clsed impeller, and both 4-vane closed and open impellers are optional. 

Different impellers selected will affect the pumps' performance slightly. At CNSME, our pump specialist will choose the right impeller for the customers based on their specific requirements from applications to applications.
