<p>A pump comprises a casing (1), a rotor (2) mounted in the casing (1) and a means for transmission of the torque to the shaft (4) of the rotor (2) from the shaft (10) of a rotation drive (9). The means for transmission of the torque consists of a sleeve-shaped head (12) corresponding by its shape to the output shaft (10) of the rotation drive (9) and provided with a longitudinal slot (14) for a keyed joint and with a torsion shaft (13). The latter is provided with figured end sections (16), whereas the bottom of the sleeve-shaped head (12) and the end-face of the shaft (4) of the rotor (2) are provided with figured axial openings (6, 15) corresponding by their shape to that of the end sections (16) of the torsion shaft (13). The pump is preferably intended for pumping food-stuffs.</p> |
