CONSTRUCTION TYPE

Sterling SIHI liquid ring vacuum pumps are displacement pumps ofuncomplicated and robust construction with the following particularfeatures:

handling of nearly all gases and vapoursnon-polluting due to nearly isothermal compressionoil-free, as no lubrication in the working chambersmall quantities of entrained liquid can be handledeasy maintenance and reliable operationlow noise and nearly free of vibrationwide choice of material, therefore applicable nearly everywhereincorporated central drainno metallic contact of the rotating parts

The Sterling SIHI liquid ring vacuum pumps LPH 40106, LPH 40411and LPH 40516 are single-stage ones. They can be applied withoutmodification 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 canbe handled during the normal duty. The pumps are applied in all fieldswhere a pressure of 150...900 mbar must be created by robustvacuum pumps.Fields of application are for example:

chemistry and pharmacy for distilling and degassingelectrics industry for impregnation and dryingplastics industry for degassing etc.

NOTE

During operation the pump must continously be supplied with serviceliquid, normally water, in order to eliminate the heat resulting from thegas compression and to replenish the liquid ring, because part of theliquid is leving the pump together with the gas. This liquid can beseparated from the gas in a liquid separator ( see catalogue partaccessories)It is possible to reuse the service liquid.The direction of rotation of the pump is clockwise, when looking fromthe drive end on the pump.
