Abstract
In a peristaltic pump having a pump tube with an elastically deformable wall, which tube is arranged in a pump housing and has externally accessible connection ends and is fitted into the pump housing with a region which is curved in part-circular configuration around a shaft of a rotor of the peristaltic pump and at a radial spacing from the shaft, the cross-section of which tube is variable by pressure rollers which project radially from the rotor and which press the pump tube at least in its curved region against a correspondingly curved fixed support, producing a reduction in the internal volume of the tube, the rotor (20) itself has mounting eyes or bores (52) for the roller spindle (54) of the pressure roller (58), which is mounted in the rotor interchangeably in an aligned pair of bores parallel to the shaft (18) of the rotor.
