Series N80U & N85U 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 N80U to N85U by changing only the seal ring and the secondary seal. This
concept is ideal for stock rationalisation. |
