Rotodynamic pump is a generic term to broadly classifies radial-vane, Francis-vane, mixed-flow and axial flow pumps. Very often, rotodynamic pump is often incorrectly interchanged with the word centrifugal pump. Strictly speaking, only radial-vane pumps are classified as centrifugal pumps. – The allowable
