Abstract
A rotary joint for use with rotating heat exchanger drums particularly suitable for installations utilizing higher fluid pressures, temperatures and rotative speeds. The joint includes a nipple mounted upon the drum shaft having an enlarged diameter portion within a body chamber upon which a pair of seals are mounted having differential pressure faces to balance fluid medium pressures imposed upon the seals, seal wear does not produce relative axial displacement between the nipple and body, and concentric alignment between the nipple and body is maintained by axially spaced alignment bushings interposed therebetween.
