摘要
A thick-matter pump for producing a continuous thick-matter flow is described. The pump includes at least two pump units, which alternate in pumping and suction operation, a suction line with a charge-pressure device, which acts separately from the pump units for actively bringing about a thick-matter compression, a delivery line, and a switchover device for switching between the pump units. In a first operating state for conveying the thick matter, by way of the switchover device, at least one first pump unit is connected during pumping operation to the delivery line and at least one second pump unit is connected during suction operation to the suction line. In a second operating state, by way of the switchover device, at least one first pump unit is connected during suction operation to the delivery line and at least one second pump unit is connected during pumping operation to the suction line, and the charge-pressure device is switched to an inactive state.
