Infinity engineers is the manufacturer of triple screw pumps. These triple screw pumps are specially designed for handling clear viscous liquids. These are suitable for differential pressures up to 16 bars. The pumping elements contain of a power screw and two idler screws, running in a close fitting insert. The idler screws serve to maintain the closed chambers that pump the liquid. Each screw is provided with a drum so that axial forces are hydraulically balanced. The shaft seal chamber is connected internally to the inlet and the seal is therefore always subjected to inlet pressure only. The inserts, screws and balancing bushes, together with bearing and seals form a replaceable cartridge that is located inside a casing.
