SIHILPH-X - Liquid Ring Vacuum Pump One Stage LPH 40106, LPH 40411, LPH 40516 VACUUM TECHNOLOGY LPH LI 2 133.71120.61.01 E 03/2008 Pressure Range: 150 to 1013 mbar Suction Range: 50 to 270 m³/h CONSTRUCTION Sterling SIHI liquid ring vacuum pumps have a simple but robust construction with the following features and benefits: Near isothermal compression Oil free, with no internal lubrication Capable of handling almost all gases and vapours 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 Cavitation protection as standard Drain hole as standard Built-in solids drain Rotating metallic parts are non contacting to minimise wear ATEX compliance Sterling SIHI liquid ring vacuum pumps of the range LPH 40106, LPH 40411 and LPH 40516 are one stage pumps. They can be used as compressors up to a pressure of 1.2 bar without any modification (see the Technical Catalogue - Liquid Ring Compressors Part K). APPLICATIONS Evacuation and pumping of dry gases and saturated vapours. The pumps can also handle liquids. These units offer pressures in the range of 150…900 mbar(a) to atmospheric. Typical application areas include: Chemical and pharmaceutical industry for distillation, drying and degassing. Electronic industry for impregnation and drying. Plastics & Rubber industry for degassing. NOTE By continuously feeding the pump 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. It can therefore be used for solvent recovery. More information is provided in the accessory catalogues. The integrated solids drain permits the removal of any entrained solids whilst the pump is operating. The service liquid can, therefore, simply be recirculated. The rotation of the pump is clockwise when viewed from the drive end.
