Our liquid pumps are optimized for operation above 200 mbar(a), making them perfect for applications such as filtration or wet conveying, with an ultimate pressure of 30 mbar(a) Liquid ring compressor—a rotary compressor that uses an impeller with vanes to transmit centrifugal force into a sealing fluid, such as water, driving it against the wall of a cylindrical casing. Lubrication system—a system that circulates and cools sealing and lubricating oils As the impeller of a liquid ring vacuum pump rotates, water (which is the typical seal liquid used in this type of vacuum pump, though other liquids can be employed) is thrown about to form a literal liquid ring. This, in turn, seals the impeller and creates separate enclosed gas chambers between each blade causing the primary ring to separate from the mating ring creating a running gap between the two rings. A sealing gas is injected into the seal, providing the working fluid for the running gap and the seal between the atmosphere or flare system and the compressor internal process gas.
