Steam rotary union FSB

multi-passageball bearinghigh-speed

Pioneered by DEUBUN, the FSB™ is a self-supported steam joint that features ball bearings and a balanced mechanical seal applicable to (in tandem with a stationary siphon) high-speed open gear machines. With the FSB, many older open gear machines may now be upgraded to utilize stationary siphons that offer the benefits of reduced differential pressure and blow-through. When teamed up with a stationary siphon, the FSB Series steam joint offers an opportunity to increase production on dryer limited machines while reducing downtime and maintenance costs. The FSB steam joint/stationary siphon combination is suitable for machine throughput speeds up to 900 MPM (3000 FPM) with a steam pressure of 3 bar (45 PSI). The balanced mechanical seal delivers improved seal life by up to four times that of conventional pressure-type seals (depending upon steam pressure, speed and paper grade.)
