The peristaltic pump (1) comprises a housing (3) provided internally with a recess (4) for receiving the deformable tube (2) and rolling tracks (5) surrounding said recess against which can press and roll the rollers (6) designed for compressing and closing that part of the tube located in the zone of contact of the rollers with the rolling tracks. The pump comprises, inside the housing (3), at least two independent arcs (10, 11) of the deformable tube, extending on different angular ranges and arranged so that the variations in the flow of each basic pump corresponding to an angular arc (110, 11) are phase-shifted, whereby the inlets (12, 15) and back flows (13, 14) of the independent arcs (10, 11) are respectively connected so that the total flow of the pump consisting of the sum of the flows of the basic arcs has reduced variations.
