two cylinder pump, in particular for the promotion of dickstoffen

摘要

In the case of twin-cylinder piston pumps having cylinders which open into a hopper and which deliver viscous material into a tapering pipe which is pivotably arranged in the hopper, there is the risk that ring-shaped, hardening deposits of constituents of the viscous material, such as sand or gravel, are formed at the delivery cylinder-side end of the pivotable pipe. In order to avoid such deposits, or to remove them, the pivotable pipe (1) which tapers towards its delivery line-side end, is designed in such a way that, at its delivery cylinder-side end, it tapers more strongly compared to the remaining cross-section of the pipe.
