VOLUTE CASINGĀ V024

The volute casing derives its name from a spiral shaped casing surrounding the pump impeller.
The purpose of the volute is to convert velocity energy to pressure energy.
A circular casing would have the impeller positioned in the center of the casing with equal space all around between the tip of the impeller and the casing wall.
