Question

A fast centrifugal pump impeller will have (1) forward facing blades (2) radial blades (3) backward facing blades (4) propeller type blades

Answer 1

The correct answer is – option 3 – Backward facing blades

 

Centrifugal pumps are the preferred hydraulic pumps that are used domestically and in industries. The impeller in the centrifugal pumps is immersed in water and imparts a centrifugal force which moves out the water particles radially.

The Impellers are known to have backward curved vanes which have less than 90 degree of blade angle. The backward curved blades are the most preferred types as they have better stabilizing power consumption characteristics than the forward and radial types which are less preferred.
