Description

by changing only the dynamic ring and the secondary seal, this principle is ideal for stock rationalization, this seals are comfortable to use in wide range of application as below:single helical coil spring unbalanced/balanced Mechanical Seals developed for dirty media & clogging type applications. It is independent of direction of rotation, torque transmission from retainer shell to dynamic ring is done through drive lugs and all components are held together by a snap ring which helps in easier installation & removal. As all parts are Interchangeable, one can convert this series by changing only the dynamic ring and the secondary seal, this principle is ideal for stock rationalization, this seals are comfortable to use in wide range of application as below:
