Liquid solvent pump
US Patent 1,, for liquid-ring vacuum pumps and compressors, was granted to Lewis H. Another application is the vacuum liquid solvent pump of molded paper-pulp products egg cartons and other packaging. This liquid is separated from the gas stream by other equipment external to the pump.
In some recirculating systems, contaminants from the gas become trapped in the ring-liquid, depending on system configuration. They are used on paper machines to dewater the pulp slurry and to extract water from press liquid solvent pump. For dry chlorine gas applications concentrated sulfuric acid is used. In vacuum service, the attainable pressure reduction is limited by the vapour pressure of the ring-liquid. The reduction in volume caused by the impeller rotation liquid solvent pump the gas, which reports to the discharge port in the end of the casing.
The liquid-ring pump compresses gas by rotating a vaned impeller located eccentrically within a cylindrical casing.
