Abstract (en)

[origin: EP0577946A2] In a tube pump with, arranged in a pump housing on its bottom, a pump tube with elastically deformable wall which is inserted into the pump housing with a part-circularly bent section around a shaft of a rotor inside the wall of the tube pump as well as at a radial spacing therefrom and the cross-section of which, during the delivery operation, is modified partially by at least one member of the rotor which presses the pump tube cross-sectionally against an abutment, the inner volume being reduced, the rotor (14) is formed in the manner of a bowl from a rotor bottom (13) and a rotor wall (15) and the latter is directed towards the bottom (38) of the pump housing (12), the shaft (16) of the rotor being attached directly to its rotor bottom. <IMAGE>
