The pump has a feed hose (14) passed between a curved hose bed (24) and a number of rollers (23) supported around the periphery of a driven carrier (22), for rotation in a circular path at a given distance to the hose bed, selected so that the hose is compressed at several points of contact. The hose bed is offset relative to the circular path of the driven rollers, so that the spacing of the rollers from the surface of the hose bed increases in the transport direction of the rollers. <IMAGE> |
