The invention relates to a conveyor device at least for conveying a fluid, comprising at least one conveyor chamber (18), at least one dimensionally stable conveyor chamber element (20) which is formed separately from a housing (14) in particular and at least partly delimits the conveyor chamber (18), and at least one elastically deformable conveyor element (22), in particular a conveyor membrane, which together with the conveyor chamber element (20) delimits the conveyor chamber (18) and is arranged on the conveyor chamber element (20). The conveyor chamber element (20) comprises at least one connecting piece (38) for a fluid supply line adapter (28), which is designed to differ from a tube in particular, and/or at least one connecting piece (40), in particular an additional connecting piece, for a fluid discharge line adapter (30), which is designed to differ from a tube in particular, said connecting piece/connecting pieces being arranged on a conveyor chamber element (20) face facing away from the conveyor element (22), in particular on the exterior of the conveyor chamber element. According to the invention, the conveyor device comprises at least one movement compensation unit (52) which is at least designed to at least partly compensate for and/or damp relative movements between the fluid supply line adapter (28) and the connecting piece (38) when the connecting piece (38) is connected to the fluid supply line adapter (28) and/or to at least partly compensate for and/or damp relative movements between the fluid discharge line adapter (30) and the connecting piece (40), in particular the additional connecting piece (40), when the connecting piece (40), in particular the additional connecting piece, is connected to the fluid discharge line adapter (30).
