Liquid ring vacuum pumps of the series SIHIextruvac LEME 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 100 to 900 mbar must be created by robust vacuum pumps. These pumps are especially developed for the use in calibration tables, where the ability of additional water handling capability (max. 7 m³/h) is needed.
Suction volume flow: up to 170 m³/h
Suction pressure: 100 up to 1013 mbar
Shaft seal: mechanical seal
Materials: grey cast iron
