Perfected twin-screw pump, particularly suitable for the pumping of biphase fluids in a submarine environment

摘要

Twin-screw pump, wherein the four conical screws are vertically arranged and are fed with biphase fluid at the two ends, independently of each other, by means of a stream divider and wherein the two screw shafts each have a central axial drilling which connects the delivery chamber to a series of radial channels which end up on the tip of the single teeth of the screws. A preferen-tial stream divider is described.
