The fitting has an operating element i.e. operation knob, movable by a lifting piston pump to convey liquid soap from a reservoir to discharge the liquid soap. A housing is divided into a base part (1) fastenable at a washbasin, and a coaxial upper part (2) vertically movably mounted at the base part. A pump piston (10) and a piston rod (11) are arranged within a pump casing (6) that is immovably fixed in the base part. The pump piston is connected with the upper part over the piston rod, and an outlet (12) is fixed at the upper part. The upper part forms the operating element. |
