The centrifugal pump has an impeller (1) with vanes (4) whose end (5) on the outlet side of the fluid is provided with at least one cut-out (6). The cut-out (6) permits a part flow of the fluid through the vane end (5) and thereby produces a quietening of the singing of the vanes of the centrifugal pump (1). <IMAGE> |
