Abstract

An impeller for centrifugal pumps having at least one blade for delivering solids-containing media has, between a leading edge of the blade and a circumferential direction, an angle α, and between a leading edge of the blade and a meridional direction, an angle β. Depending on the dominant speed, the associated angles α, β are less than 90°, preferably less than 70°, in particular less than 50°.
