- Liquid Ring Vacuum Pump Two Stage LPH 45008, LPH 45311, LPH 45316 Pressure Range: Suction Volume: 33 to 1013 mbar 55 to 258 m³/h CONSTRUCTION Sterling SIHIliquid ring vacuum pumps have a simple but robust construction with the fo lowing features and benefits: Near isothermalcompression Oilfree,with no internallubrication Capable ofhandling almost a lgases and vapours Able to handle quantities ofliquid carry over Low maintenance and safe operation Low noise and almost vibration free Available in a wide range ofmaterials Broad range ofapplications O-ring sealing as standard Cavitation protection as standard Drain hole as standard Built-in solids drain Rotating meta lic parts are non contacting to minimise wear ATEX compliance Sterling SIHIliquid ring vacuum pumps ofthe range LPH 45008, LPH 45311 and LPH 45316 are two stage pumps. In addition,the LPH 45008 and LPH 45316 can be used as compressors without any modification. (see the Technical Catalogue - Liquid Ring Compressors) APPLICATIONS Evacuation and pumping ofdry gases and saturated vapours. The pumps can also handle liquids. These units o fer pressures in the range of33...900 mbar(a)to atmospheric. Much lower pressures are available by using ancilaries such as ejectors and lobular boosting pumps. Typicalapplication areas include: Chemicaland pharmaceuticalindustry for distilation,drying and degassing Food and beverage industry for low temperature cooking, and bottle filing Electronic industry for impregnation and drying Plastics & Rubber industry for degassing Healthcare for sterilisers and generalvacuum Note By continuously feeding the pump with a sma lamount ofservice liquid (usua ly 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 liquid separator. More information is provided in the accessory catalogues. The integrated solids drain permits the removalofany entrained solids whilst the pump is operating. The service liquid can therefore, simply be re-circulated. The rotation of the pump is clockwise when viewed from the drive end.
