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

Low noise and nearly free from 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 LOH 20103 and LOH 20107 are single-stage ones. They can be applied without modification as compressors up to a compression pressure of 1 bar (see catalogue part K).

APPLICATION

Handling and exhausting of dry and humid gases; entrained liquid can be handled during normal duty. The pumps are applied in all fields where a pressure of 150 to 900 mbar must be created by robust vacuum pumps.

Fields of application are for example:

chemistry and pharmacy for distilling and

degassing,

electric industry for impregnation and drying

plastics industry for degassing etc.

NOTE

During operation the pump must be continuously supplied with service liquid, normally water, in order to eliminate the heat resulting from gas compression and in order to replenish the liquid ring, because part of the liquid is leaving the pump together with the gas. This liquid can be separated from the gas in a liquid separator (see catalogue part accessories).

Reuse of the service liquid is possible.

The direction of rotation of the pump is clockwise when looking from the drive on the pump.
