A first hose (22) is connected to the forcing and lifting joints and is arranged on the inner wall (24) of the housing (10). Squeezing elements (26) can be moved along the hose (22) in such a manner that said hose can be squeezed together by each of the squeezing elements from the direction of the lifting joint (12) to the direction of the forcing joint (14). Said hose pump is characterized by at least a second hose (32), which is elastically deformable, its one extremity (44) ending in the internal part (46) of the housing (10) and its other extremity (50) ending outside the housing (10); said second hose is placed in the internal part (46) of the housing is such a manner that it can be squeezed together from the direction of its one extremity (44) to the direction of its other extremity (50) by the movement of at least two additional squeezing elements (26) moving along it.
