AVV units on the liquid ring vacuum pumps basis

The AVV units based on liquid ring vacuum pumps 3VVN with ejector stage installed oт the suction pipe of the pump are used for creation and maintaining vacuum in the working pressure range from atmospheric to 10 Torr. Ejector stage allows to increase the capacity of the pump at the inlet pressure low then 150 Torr and reach  higher vacuum 5·10-5 Torr.      

This units are designed for operating with liquids, slow-soluble in luqids gases and vapors which are nontoxic, fire and explosion hazardous and non-agressive to construction materials.
