Abstract

1. Apparatus for conveying slurries, comprising at least two two-cylinder piston pumps, the cylinders of which can be connected by a valve alternately with the feed of the slurry and with the delivery pipe, and wherein both two cylinder piston pumps deliver into a common delivery pipe and the second two-cylinder piston pump operates displaced by a quarter-cycle in time from the first, characterized in that the inlet of the delivery pipes (10 and 12) of the two two-cylinder piston pumps (A and B) into the common delivery pipe (15) is effected by a pivoting flap valve (14).
