Abstract
The present invention relates to a thick matter pump comprising at least two pump units alternating in the pump and suction mode, a delivery line, a suction line and a switching valve for switching between the pump units, one pump unit being connected in the pump mode by the switching valve to the delivery line, and one pump unit being connected to the suction line in the suction mode. The filling level of the pump unit in the suction mode is to be improved. To this end a pressure boosting device which acts independently of the pump units is provided in the area of the suction line for actively effecting a precompression of thick matter. The invention also relates to a suction/pumping method which is carried out by said thick matter pump.
Claims23
A thick matter pump comprising at least two pump units (1, 2) alternating in the pump and suction mode, a delivery line, a suction line, and a switching valve (11) for switching between said pump units (1, 2), one pump unit (1, 2) being connected in the pump mode by said switching valve (11) to said delivery line, and one pump unit (1, 2) being connected in the suction mode to said suction line, characterized in that a pressure boosting device (17) which operates independently of said pump units (1, 2) is provided in the area of said suction line for actively effecting a thick matter compression.
