Get PriceThe impeller is the hydraulic component that rotates to impart velocity to the pumped liquid. "A centrifugal pump converts velocity into flow." Every centrifugal pump includes a casing. The casing is the hydraulic component that captures the velocity imparted by the impeller and directs the pumped liquid to the pump discharge point.
