Water rotary union FG™

multi-passage

Designed specifically for Yankee Dryers, FG™ Series joints are externally supported, with the seal ring assembly attached to the rotating cylinder journal, while the counter seal is attached to the stationary joint body. The joint body is rigidly secured to the machine frame by a bell, bracket or rod support. While pressure-type joints use operating pressure to maintain sealing, FG Series joints use mechanical seals to lower seal contact pressure and thus reduce wear and extend seal life, even under high-pressure conditions. Seal wear is fully compensated through provisions for axial movement of internal seal components. The joint body remains fixed throughout the life of the seal. The FG series will also accommodate dryers fitted with CARB* bearings.
