Liquid ring vacuum pumps single-stage LPH 40106, LPH 40411, LPH 40516 Pressure range: Suction volume flow: 150 to 1013 mbar 50 to 270 m³/h CONSTRUCTION TYPE Sterling SIHI liquid ring vacuum pumps are displacement pumps of uncomplicated and robust construction with the following particular features: handling of nearly all gases and vapours non-polluting due to nearly isothermal compression oil-free, as no lubrication in the working chamber small quantities of entrained liquid can be handled easy maintenance and reliable operation low noise and nearly free of vibration wide choice of material, therefore applicable nearly everywhere incorporated central drain no metallic contact of the rotating parts The Sterling SIHI liquid ring vacuum pumps LPH 40106, LPH 40411 and LPH 40516 are single-stage ones. They can be applied without modification as compressors up to a compression pressure of 1,2 bar ( see catalogue part K). APPLICATION Handling and exhausting of dry and humid gases; entrained liquid can be handled during the normal duty. The pumps are applied in all fields where a pressure of 150...900 mbar must be created by robust vacuum pumps. Fields of application are for example: chemistry and pharmacy for distilling and degassing electrics industry for impregnation and drying plastics industry for degassing etc. NOTE During operation the pump must continously be supplied with service liquid, normally water, in order to eliminate the heat resulting from the gas compression and to replenish the liquid ring, because part of the liquid is leving the pump together with the gas. This liquid can be separated from the gas in a liquid separator ( see catalogue part accessories) It is possible to reuse the service liquid. The direction of rotation of the pump is clockwise, when looking from the drive end on the pump.
