In an apparatus for conveying concrete, comprising a pump with pistons arranged mutually parallel, which conveys the concrete, which can be supplied via a funnel, alternately into a pressure pipe via an S-shaped distributor arranged pivotably in the funnel, the funnel being connected at its rear wall to the cylinders of the pump via openings lying in one plane and the openings being alternately connectable to the pressure pipe by the distributor, at least three pump cylinders (6) arranged in symmetrical distribution on the circular line ( epsilon ) and having corresponding openings (5) being provided. The distributor (9) is structurally defined so that it always covers at least two pump cylinders (6) on the inlet side and is pivotable stepwise through the round angle and a multiple thereof. With a concrete pump of this type, it is possible to obtain a continuous conveying stream. <IMAGE>
