The invention relates to a screw pump (1), in particular a twin screw pump, comprising: a multi-part housing (2, 7, 15, 21) and at least two coupled chamber-forming rotors (3, 3a), each The rotors each comprise at least one thread-like profile (4, 4a) formed at least in regions and having a helical channel (5, 5a) and a dividing wall ( 6, 6a), wherein the rotors (3, 3a) perform reverse rotor rotations and the partition walls (6, 6a) mesh with each other in the manner of gears; and the running housing part (7), wherein the running housing part (7) surrounding the rotor (3, 3a) in a non-contact manner, wherein the rotor (3, 3a) together with the running housing part (7) forms at least one delivery chamber (8, 8a) for the fluid to be delivered, Among them, the transfer chamber (8, 8a) moves axially along the rotor shaft (10, 10a) and transfers the fluid from the suction chamber (11) to the pressure chamber (12); the suction side connection element (13), which is fluidly connected to a suction chamber (11); and a pressure-side connecting element (14), which is fluidly connected to the pressure chamber (12), wherein the suction-side connecting element (13) and the pressure-side connecting element (14) are arranged in the multi-part housing (2 , 7, 15, 21) on the connecting housing part (15), wherein the housing (2, 7, 15, 21) includes a planar dividing surface (16), which is in the running housing part ( 7) and the connecting housing part (15) extend parallel to the rotor shaft (10, 10a).
