Product Information LEM, LEL

SIHI Vacuum pump type LEM

Liquid ring vacuum pumps of the series LEM/LEL are single-stage displacement pumps of uncomplicated and robust construction with the following particular features like non-polluting due to nearly isothermal compression, oil-free (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, protection against cavitation as standard, incorporated dirt drain, incorporated central drain and no metallic contact of the rotating parts.



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.
