in orderto prevent dry gas seal from contamination of lubricating oil,
at the same timethe process gas is prevented from going into lubricating oil.
BG series of dry gas seal can work well with either carbon ring or labyrinth.
Outboard separation sealFeatures
Labyrinth Seal
Simple structure,simple instalation procedure;
Higher consumption of seal gas.
Carbon Ring Seal
Lower consumption of N2,only 20%～30% of labyrinth, better oil proof ability;
More complicated installation and maintenance.
