SIHILPH-X- Liquid Ring Compressors LPH 40106, LPH 40411 LPH 45008, LPH 45316 VACUUM TECHNOLOGY KPH K 4 133.72120.56.01 E 08/2006 Pressure range: 0.2 to 1.5 bar Suction volume range: 55 to 175 m³/h CONSTRUCTION Sterling SIHI liquid ring compressors are displacement compressors with a simple but robust construction and the following features and benefits: Can handle almost all gases and vapours Near isothermal compression Oil free with no internal lubrication required Able to handle quantities of liquid carry over Low maintenance and safe operation Low noise and almost vibration free Available in a wide range of materials Broad range of applications O-Ring sealing as standard Central drain plug as standard Built in solids drain Rotating metallic parts are non contacting to minimise wear The Sterling SIHI liquid ring compressors LPH 40106 and LPH 40411 are one stage. They can be used without modification as vacuum pumps up to a suction pressure of 150 mbar (for more information see Catalogue Part LI 2). The Sterling SIHI liquid ring compressors LPH 45008 and LPH 45316 are two stage. They can be used without modification as vacuum pumps up to a suction pressure of 33 mbar (for more information see Catalogue Part LII 3). APPLICATION Transport and compression of dry gases and saturated vapours. The pumps can also handle liquids. Compressors are used typically where a pressure of up to 1.5 bar is required and only a limited temperature increase due to the compression is permitted. Applications include: - The plastics processing industry for the recovery of gases such as vinyl chloride - The petrochemical industry for the compression of flammable gases such as petroleum vapours or hydrogen - Gas transfer 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. The condensed gas and fluid can be separated in a liquid separator (see Accessories Catalogue). Recharging the pump with service liquid at ambient temperature enables the unit to condense evacuated gases/vapours. More information is provided in the accessory catalogues. The rotation of the pump is clockwise when viewed from the drive side.
