The aim of the invention is to provide a simple, smoothly running pump, especially a slurry pump, preferably for concrete, which comprises a driven rotor (4) rotating inside a housing (2). According to the invention, the rotor (4) is configured as a polygonal, prismatic body wherein at least the connecting lines of the corners of the base form an equilateral polygon. The rotor performs a rotational movement about its center axis on an orbit, the longitudinal edges of the prismatic body (4') touching the longitudinal inner wall surface (2') of the housing (2).

L'objectif de l'invention est de créer une pompe tournant de façon régulière, construite de manière simple, en particulier une pompe pour liquides épais, de préférence pour le béton, comprenant un rotor (4) annulaire, entraîné, placé dans un logement (2). A cet effet, le rotor (4) est formé comme un corps sous forme de prisme polygonal, dans lequel au moins les lignes de raccordement des coins de surfaces de base forment un polygone équilatéral. Ledit rotor effectue un mouvement de rotation autour de son axe central se déplaçant sur une trajectoire circulaire. Les arêtes longitudinales du corps (4') sous forme de prisme touchent la paroi (2') interne longitudinale du logement (2).
