The pump has a running wheel spaced at a distance from an inlet (3) such that a free passage (7) is provided between the inlet and a running wheel outlet. A running wheel base of the outlet is formed through a front side (24) of a hub body and underlying plate surface (28), where the body is projected in center part of the wheel. The base is provided in an inner region of the pump, where the radius of the inner region is smaller than height difference between an inner end of blade front surfaces (30, 35) and a maximum depth of the plate surface based on the inner end of the front surfaces. |
