Abstract
An impeller for a centrifugal pump for pumping fluid containing solid particles includes: a rear side wall; a front side wall; a plurality of vanes located between the rear side wall and the front side wall, each vane having an outer edge and a vane width in an axial direction of the impeller. At least one of a periphery of the rear side wall or a periphery of the front side wall projects by a radial distance beyond the outer edges of the vanes, the radial distance being at least 0.5 times the vane width.
