Liquid ring compressors LOH 05501 VACUUM TECHNOLOGY KPH K 1 133.72105.54.01 E 12/2008 Compression pressure: 0.2 to 2 bar Volume flow: 2.8 to 4.8 m³/h CONSTRUCTION Sterling SIHI liquid ring compressors have a simple but robust construction with the following features and benefits: Capable of handling almost all gases and vapours Near isothermal compression Oil-free, with no internal lubrication Low maintenance and safe operation Low noise and almost vibration free Available in a wide range of materials Broad range of applications Rotating metallic parts are non contacting to minimise wear ATEX compliance The LOH 05501 operates according to side channel principle and therefore the pump has the advantage, besides the abovementioned features to handle large quantities of entrained liquid. Sterling SIHI liquid ring compressors of the range LOH 05501 are two-stage compressors. They can be used as vacuum pumps up to a suction pressure of 80 mbar without any modification. (See the Technical Catalogue – Liquid Ring Vacuum Pumps). APPLICATIONS Pumping and compressing of dry gases and saturated vapours; the compressors can also handle liquids. The compressors are applied in all fields where a compression over pressure of up to 2 bar has to be created by robust compressors and only a small increase in temperature is admissible during compression. Typical application areas include: - the plastics industry, for recovery of process gases as vinyl chloride - the petrochemical industry, for the compression of combustible gases as gasoline vapours or hydrogen - transport of gases in general e.g. to a reactor NOTE By continuously feeding the compressor with a small amount of service liquid (usually water), the heat due to gas/vapour compression is conducted away. This also replenishes the liquid ring and ensures that it does not become saturated with process media. Recharging the pump with service liquid at ambient temperature enables the unit to condense evacuated gases/vapours. It can therefore be used for solvent recovery. The condensed gas and liquid can be separated in a pressure liquid separator. More information is provided in the accessory catalogues. The service liquid can simply be re-circulated. The rotation of the pump is clockwise when viewed from the drive end.
