The invention relates to a device for delivering thick matter. The device comprises: a delivery cylinder (20); a material feed space (16), which is connected to the delivery cylinder (20) on the entry side; a delivery line (18), which is connected to the delivery cylinder (20) on the exit side; a delivery plunger (12), which can be displaced to-and-fro through the material feed space (16) and the delivery cylinder (20), and; a closing element (22), which is placed at the exit location of the delivery cylinder (20) or inside the delivery line (18) and which can be displaced between an open position and a closing position. In order to be able to separate foreign substances, which are contained in the flow of thick matter, out of the flow of thick matter before the actual processing step for the useful substances, the invention provides that the delivery cylinder (20) is perforated at least over a portion of its cylinder jacket (24). These measures make it possible to obtain a device that combines the features of a thick matter pump, a sieve and a press.
