liquid ring vacuum pump / oil-free / single-stage / low-noise

The Sihi sterivac LEMS liquid ring vacuum pumps are single-stage displacement pumps of simple and robust construction with the following features: non-polluting due to nearly isothermal compression, oil-free (no lubrication in the working chamber), handles nearly all gases and vapours. Small quantities of entrained liquids can be easily dealt with, and the pump itself is easy to handle and is also simple to maintain. Very low noise, and virtually vibration free and with protection against cavitation coming as standard, this pump is ideal for the handling and exhausting of dry and humid gas. 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 a robust vacuum pump. Also features a suction volume flow of up to 57 m?/h, and a suction pressure of 33 up to 1013 mbar.
