Series 80U & 85U are multiple spring units developed for universal application. Their compact design permits their
use in all types of centrifugal pumps. Torque transmission from retainer shell to seal ring is done through drive lugs.
All components are held together by a snap ring which helps in easier installation and removal. As all parts are
interchangeable, one can convert series 80U to 85U by changing only the seal ring and the secondary seal. This concept
is ideal for stock rationalisation. |
