A pump comprises a body with a cover and a working wheel with a drive disc and blades installed in it on the shaft. In peripheral section of the blades, coaxially to the shaft, concentric arc-like slots are provided. On the cover of the body blades are fixed, as concentric rings with radial slots. The blades are placed with gap in the slots of the blades. To improve dispersion of suspensions, exclude accumulation in after-disc space of not processed suspensions and penetration of those to treated liquid, in the drive disc, between blades, through openings are provided.
