MACHINE TYPE: Liquid ring pump SECTOR OF USE: Chemical, Pharmaceutical, Food, Environmental DETAILS: The liquid ring vacuum pump uses the rotation of an impeller to create a ring of liquid that acts both as a sealant and as a compression medium. This mechanism generates cavities that expand to draw in gas and contract to compress and discharge it. Thanks to this technology, the pump can handle moist gases, vapors, and liquids, absorb compression heat, and offer great reliability and robustness, with reduced wear.
