The invention relates to a pump (1) for dispensing semi-liquid food products, which comprises an inlet opening (6), an outlet opening (7), a dispensing path (P) between the inlet opening (6) and the outlet opening (7), a rotor (8) for pushing the product along the dispensing path (P), and an airtight chamber (9), which is interposed between the inlet and outlet openings (6, 7) and coaxially contains the rotor (8)； the dispensing path (P) is defined by the cyclically choked gap formed between the outer periphery (14) of the rotor (8), equipped with three projecting and angularly equidistant lobes (15) and the inner periphery (13) of the chamber (9), which is elastically deformable.
