Abstract (en)
[origin: EP1961969A2] The axial flow radial impeller (10) has a driven supporting part (18,118), which extends perpendicular to the rotating axis (12). A blade arrangement is provided with a number of crown-shaped impeller blades (20) peripherally arranged spaced from each other. The additional blades (44) are engaged in rotating direction (V) of the impeller such that the particles contained in the liquid to be conveyed are subjected to a force component aligned towards supporting part.
