Abstract
A solid material pump comprising a pump housing, a pair of parallel pump cylinders driven by hydraulic cylinders and each connected to a pump chamber, a slurry feed device which communicates via inlet valves with inlet valve chambers each of which communicates with a pump chamber, the axes of valve cylinders for actuating the inlet valves extending in parallel and spaced relationship to the axes of the pump cylinders and the inlet openings being provided at the pump housing opposite to the pump cylinder whereby the sucked-in flow is deflected twice, further comprising outlet valve chambers adapted to communicate via outlet valves each with a pump chamber and connected to a common outlet conduit, with the valve cylinders for actuating the outlet valves being connected to the pump housing on the side opposite to the inlet valve cylinders and their axes extending in parallel and spaced relationship to the axes of the pump cylinders and the inlet valve cylinders. The axes of the inlet cylinders and the pump cylinders are so close to each other and the pump chamber, the inlet valve chamber and the junction zone are formed so and merge into each other such that the sucked-in flow is defl…
