Abstract
A pump for pumping a mixture of a liquid and a coarse-grained material comprises a motor-driven rotor (1) having a plurality of longitudinal cylinders (5, 6, 7, 8) having individual piston members (9), whereby these are driven back and forth by means of a pressure medium which is supplied to one end of the rotor. At the other end of the rotor, the cylinder openings, during rotation, pass a stationary inlet channel (21) and a stationary outlet channel (22) for the mass that is to be pumped. The rotor (1) is designed as a truncated cone, the cylinders being obliquely positioned with respect to the axis of rotation and having the greatest radial distance thereto at the cylinder ends which cooperate with the above-mentioned inlet and outlet channels.
