Triple Passage Rotorseals

Type BTA
The BTA rotorseal was designed for simultaneous transfer of as many as three different fluids. A mounting flange simplifies installation to the shaft end. Three 1/2-14 American National Pipe Thread inlet ports on the side of the stationary rotorseal body provide access to the concentric fluid passages. All three passages can discharge directly into the rotating shaft. However, a 1/2-14 port in the mounting flange can be used as an optional outlet for the outermost passage.
