SGB Pump Volute Casing description
Product Description The pump volute casing is the most common type of centrifugal pump. Its characteristic feature is the volute-shaped pump casing which is typical for single-stage centrifugal pumps . The pump parts volute casing is specially designed to constrict the fluid from the pump inlet, direct it into the impeller and then slow and control the fluid before discharge. A pump volute casing is a curved funnel that increases in area as it approaches the discharge port. The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge. As the fluid travels along the volute it is joined by more and more fluid exiting the impeller but, as the cross sectional area of the volute increases, the velocity is maintained ...
