Abstract (en)
A pump (1) for circulating a medium comprises: an elastically deformable hose (4) which lies against a pressing surface (3), with a medium inlet (6) and a medium outlet (7); and pressing elements (9,10) which move along the hose and press the hose part in contact with a pressing element against the pressing surface while locally compressing and closing the hose part; whereby medium is drawn in via the medium inlet and discharged under pressure via the medium outlet. The pump has the special feature that a cavity (15) is defined in the pump housing (2), the pressing surface of which cavity forms a boundary and in which cavity the hose and the pressing means with the pressing elements are accommodated; and the cavity is hermetically sealed and filled with a filling medium.
