    • The invention relates to an installation piece for supporting a roller in a roller stand of a roller frame. The installation piece comprises a main bore for receiving a journal of the roller, an inlet (120) for a lubricant, an outlet for the lubricant, and a pump device (130) for pumping the lubricant leaving the installation piece through the outlet. The pump device has a housing (132), an inlet channel (134), and an outlet channel (136), said inlet channel communicating with the inlet and said outlet channel communicating with the outlet for the flow of the lubricant. The pump device is driven by the flow of the lubricant in the inlet. The invention describes a pump device for an installation piece as an alternative to the prior art. The housing of the pump device according to the invention is equipped with a screw pump (137) and a turbine (139), which is driven by the pressurized inflowing lubricant, in the inlet channel for driving the screw pump.
