Abstract (en)
[origin: WO2019025238A1] The invention relates to an impeller (2) for centrifugal pumps having at least one blade (12). Said impeller (2) is used for delivering solids-containing media. The angle a is at an angle between a leading edge (17) of the blade (12) and a circumferential direction. The angle β is an angle between a leading edge (17) of the blade (12) and a meridional direction. Depending on the dominant speed, the associated a, β is designed to be less than 90°, preferably less than 70°, in particular less than 50°.<i />
