For over 80 years we have been a leading manufacturer of innovative technologies for liquid ring vacuum pumps, liquid ring compressors, dry running vacuum pumps and gas ejectors.
Liquid ring vacuum pumps of the series LEMD 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 vapors, 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.
Suction volume flow: up to 450 m³/h
Suction pressure: 33 up to 1013 mbar
Shaft seal: mechanical seal
Materials: grey cast iron, stainless steel
