Dual passage rotorseals allow the transfer of media through two separate shaft passages located on the same shaft end. Each passage can be used for a different medium; for instance, air for clutch actuation and oil for bearing lubrication. Inlet and outlet ports have American National Pipe Threads.

Dual Passage Rotorseals
Description N/A The AD rotorseal has 1/4-18 inlet ports for each of the passages. Both passage outlets can discharge directly into the shaft end. An optional 1/4-18 outlet port in the mounting flange could be used for the outer passage. The inner passage nose is sealed on its outside diameter by a pair of "O" rings. The outer passage is sealed to the shaft end with a compression grommet. N/A The type ADP rotorseal attaches to the shaft end with a 1-11 1/2 thread outlet instead of a mounting flange. The outer passage outlet feeds into the end of the machine shaft. The inner passage is a 1/4-18 port located on a flat of the hex mounting nut. N/A The type BD is similar to the AD, except for a larger diameter mounting flange. The inner passage is sealed with a flat rubber washer which compresses on the bottom of a counterbore in the shaft end. A compression grommet is used between the shaft end and mounting flange to seal the outer passage. N/A The FDA type rotorseal has larger passages than the BD rotorseal. The two inlet ports and the two flange outlet ports for the outer passage are 1/2-14. Compression grommets are used between the shaft end and mounting flange to seal the inner and outer passages.
