liquid ring vacuum pump / oil-free / single-stage / stainless steel

LOH series liquid ring vacuum pumps represent single-stage displacement pumps designed with simple and robust construction. The pumps include several particular features such as handling of nearly all gases and vapours, oil-free (no lubrication in the working chamber), easy maintenance and reliable, low noise and nearly free from vibration. The pumps include nearly isothermal compression making them pollution free. They are capable of handling small quantities of entrained liquid. LOh series pumps are available in various types of materials (therefore applicable nearly everywhere), includes central drain and are free from metallic contact of the rotating parts.

The pumps are designed for handling and exhausting of dry, humid gases and entrained liquid during normal duty. They are also used in applications where robust vacuum pumps require 150 to 900 mbar pressure. The pumps are widely used in chemical and pharmaceutical industry (distilling and degassing), electric industry (impregnation and drying), plastics industry (degassing) and several other fields.
