Abstract (en)

The invention relates to a peristaltic pump comprising an electric motor (1) having a bearing (2) and an output shaft (4a) rotating about an axis of rotation (4b); a pump body (3) mounted stationary on the said bearing (2); a cylindrical casing (8) whose axis of symmetry (5) is parallel to the output shaft (4a); a rotor (6, 7) mounted fixedly on and rotationally driven by the output shaft (4a) inside the cylindrical casing (8); a planet wheel (9, 10) of the rotor (6, 7) rotationally driven inside the casing (8); a flexible tube (11) lining the internal lateral wall (18) of the casing (8) and compressed between the planet wheel (9, 10) and the lateral wall (18). According to the invention, the distance between the axis of rotation (4b) and the distal end of the rotor (6, 7)/planet wheel (9, 10) arrangement added to the thickness of the compressed tube (11) is greater than the radius of the cylindrical casing, the said cylindrical casing (8) being mounted elastically on the pump body (3) through the use of external elastic elements (12). <IMAGE>
