An apparatus for treating pulp with a treatment liquid, comprising a vessel (1) with a cylindrical wall (2), an internal straining member (3) for drawing off liquid from the pulp, together with a number of distribution pipes (5) on the outside of the vessel for supplying treatment liquid into the vessel via a number of inlet connections (6). According to the invention, each distribution pipe (5) is formed by an annular profile (20) and an opposite part (21) of the cylinder wail (2), the profile being welded firmly directly to the cylinder wall, and the profile and the cylinder wall part enclosing between them a distribution duct (22). Furthermore, each inlet connection (6) has an opening (23) which extends through the cylinder wall part and connects the distribution duct to the interior of the vessel.
