Kinney Liquid ring pumps are sealed with liquid and are ideal for pumping wet gas mixtures and even slugs of liquid. They are available in standard, all iron (no copper), and 316 stainless steel.
Low pressure performance is limited by the vapor pressure of the sealing liquid which can be water, oil, or process liquids. Most liquid ring pumps require water cooling, but air-cooled systems are available.
Single stage pumps operate best above 250 Torr and two stage pumps below.
