centrifugal pump impeller vane profile|Impellers Selection Guide: Types, Features, Applications : consultant
Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a volute chamber / casing, from where it exits into the downstream piping. Centrifugal pumps are used for large discharge through smaller heads.
