Abstract
Concrete-pump system with a swing pipe into which in each case one of two piston pumps delivers in successive alternation while the other piston pump in each case sucks in the concrete subsequently to be delivered into the swing pipe. The swing pipe is arranged on a floatingly mounted swivelling shaft. The cylinders of the piston pumps end in a plate against which that end of the swing pipe which is associated with the piston pumps rests, an adjusting-spring arrangement ensuring that the end of the swing pipe rests against the plate in leakproof fashion over a long period of operation.
