The invention relates to a thick material pump having a first delivery cylinder, a second delivery cylinder and an additional cylinder. The additional cylinder serves for bridging a transition between the first delivery cylinder and the second delivery cylinder. The thick material pump comprises a movable tube portion which forms a connection between the first delivery cylinder and an outlet of the thick material pump in a first state and which forms a connection between the second delivery cylinder and the outlet of the thick material pump in a second state. The movable tube portion comprises a switchable closure which is arranged between an inlet end of the movable tube portion and the additional cylinder. The thick material pump according to the invention makes it possible for a uniform material flow to be delivered in the direction of the pump outlet.
A thick material pump having a first delivery cylinder (20), a second delivery cylinder (21) and an additional cylinder (22) for bridging a transition between the first delivery cylinder (20) and the second delivery cylinder (21), and having a movable tube section (24) which, in a first position, forms a connection between the first delivery cylinder (20) and an outlet (23) of the thick material pump, and which in a second position forms a connection between the second delivery cylinder (21) and the outlet (23) of the thick material pump, wherein the movable tube section (24) comprises a switchable closure (27) which is arranged between an inlet end (25) of the movable tube section (24) and the additional cylinder (22), wherein the movable tube section (24) comprises a first partial section which extends between the inlet end (25) and the closure (27) and a second partial section which extends between the closure (27) and the additional cylinder (22).
