Abstract

A pump for concrete and other sludgy materials comprises a hopper with two parallel pump cylinders connected to the hopper, the open (head) ends of the cylinders opening to the interior of the hopper. A C-shaped discharge pipe is disposed in the hopper with its upper end connected to a delivery pipe which is disposed above the pump cylinders and which has its inlet end facing in the same direction as the head ends of the cylinders. The discharge pipe is oscillated to and fro about an axis above and parallel to the pump cylinders to bring the lower end of the discharge pipe into register with the open ends of the two pump cylinders alternately. Means may be provided for pressing the lower end of the discharge pipe against the open ends of the pump cylinders to minimise leakage.
