AIRFLEX TRIPLE PASSAGE ROTORSEALS TYPE BTA, TYPE RT

TRIPLE PASSAGE ROTORSEALS Type BTA The BTA rotorseal was designed for simultaneous transfer of as many as three different fluids. Three 1/ 2-14 American National Pipe thread inlet ports on the side of the stationary body provide access to the concentric fluid passages. All three passages can discharge directly into the rotating shaft. A 1/ 2-14 port in the mounting flange can be used as an optional outlet for the outer most passage. Type RT The RT rotorseal has two 1" and one 0.5" diameter passageways and is available in a standard cast iron shaft design or a corrosion-resistant model with a brass shaft. The rotating seal is provided by a non-metallic sealing ring, held against the rotorseal shaft by a light spring force. The design promotes positive protection against leakage and minimal seal wear. Ball bearings are used between the stationary and rotating ports to provide rigidity to the rotorseal assembly and to minimize the running torque.
