A positive-displacement pump (1) consists of a containment body (2) having a first and a second pipe (3a, 3b) for the passage of a liquid to be pumped. The pipes (3a, 3b) are both in fluid communication with a cavity (7) made in the containment body (2). The cavity (7) houses a rotor (11) moved by movement means (12). The pump (1) also has a movement part (15) attached to the containment body (2) for moving the body (2) relative to the rotor (11).
