ABSTRACT:
The cylinders of two plunger-type slurry pumps on a truck delivering concrete mixture to a constructions site are connected to openings in the bottom of a bin and alternatively connected to a discharge conduit by a tubular connector movable in the bin between positions of at least approximate sealing engagement with the openings. The useful life of the connector and of associated devices is improved by supporting the connector on a rigid frame above the bin.
