Description

Liquid ring vacuum pumpsin compact design LEM 91, LEM 126, LEM 161 LEL 91, LEL 126, LEL 161 with threaded connection Pressure range: Suction volume flow: 33 to 1013 mbar 24 to 195 m³/h CONSTRUCTION SIHI liquid ring vacuum pumps are displacement pumps of uncomplicated and robust construction with the following particular features: non-polluting due to nearly isothermal compression oil-free, as no lubrication in the working chamber handling of nearly all gases and vapours small quantities of entrained liquid can be handled easy maintenance and reliable operation low noise and nearly free from vibration wide choice of material, therefore applicable nearly everywhere protection against cavitation as standard incorporated dirt drain incorporated central drain no metallic contact of the rotating parts The SIHI liquid ring vacuum pumps LEM/LEL are single-stage ones. 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 33 to 900 mbar must be created by robust vacuum pumps. NOTE During operation the pump must continuously 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 leaving 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 pumps are equipped with a device by which the contaminated service liquid can continuously be drained during operation (dirt drain), if necessary. The direction of rotation is clockwise, when looking from the drive on the pump.
