Series N70U & N75U are single helical coil spring seals developed for dirty media and clogging type applications. 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 N70U & N75U by
changing only the seal ring and the secondary seal. This concept is ideal for stock rationalisation. |
