ABSTRACT:
In a double-cylinder pump for conveying cement, a distribution pipe is pivotally driven into alignment with each of the cylinders in turn. A wearing ring, which provides a seal between the end of the pipe and the cylinders, is mounted so as to be movable with respect to the end of the pipe so as to be able to assimilate wear.
