Abstract

A rotary positive displacement pump comprising a pump housing (2) that has a rotor casing (4) with an inlet (401) and an outlet (402), wherein a first rotor (6) and a second rotor (7) are arranged in the rotor casing (4) for effecting pumping of a liquid. A first support (16) is fixedly connected to the pump housing (2), a first support sleeve (14) is rotatably arranged on the first support (16), a first gear (18) is connected to the first support sleeve (14)and the first rotor (6) is connected to the first support sleeve (14). The pump has a corresponding second support (17), second support sleeve (15) and second gear (19). The second rotor (7) is connected to the second support sleeve (15) and the second gear (19) is in mesh with the first gear (18), for effecting simultaneous rotation of the rotors (6, 7).
