The delivery mechanism 1 is connected to the stator 2 by two pairs of articulated connecting rods 11, on the one hand on the vertical members 10 integral with the base 9, and on the other at the ends of the rigid body 12. The latter is formed by the runners 13 and 14 and cross members 15. It supports and guides the pulleys 17, which guide the chains 18 driving the rollers 20 and 21. The pipe 3 is arranged horizontally and anchored between the jaws 4 and 5, the upper surfaces of which form a flat, horizontal trough intended to receive a lubricant. The connecting rods 11 allow the rollers 21 to be distanced from the tube 3 in order to facilitate dismantling and/or cleaning of the pump. <IMAGE>
