An infusion pump for syringes, comprising a supporting structure (2), a support (3) for a syringe (4), which can be rigidly associated with the syringe (4) and can be associated with the supporting structure (2) so that they can rotate alternately about an axis (A) that is substantially perpendicular to the longitudinal axis (B) of the syringe (4), and a first actuation (5) for actuating the alternating rotation and a second actuation (6) for actuating the sliding of the plunger (4b) of the syringe (4), which cooperate functionally with the first actuation (5).
