The NASH 2BG two stage liquid ring compressor is based on the flat sided liquid ring pump and compressor design. Engineered to withstand the harshest chemical, petrochemical and oil & gas processes, the 2BG compressors have cylindrical roller bearings and a fixed deep-groove ball bearing which is sprung to eliminate play. The result is a powerful liquid ring compressor with low maintenance requirements. Our 2BG compressors can handle a wide range of gases and can accommodate special seal liquids such as petrol or oil when compatible with the process gas.
