Multi Spring Unbalanced/Balanced Mechanical Seals (Close Type)


Share This :

Description

Multiple springs unbalanced/balanced Mechanical Seal developed for universal applications. It is independent of direction of rotation, torque transmission from retainer shell to dynamic ring is done through drive lugs, their compact design permits their used in all types of centrifugal pumps and all components are held together by a snap ring which helps in easier installation & removal. As all parts are interchangeable by changing only the dynamic ring & the secondary seal, this principle is Ideal for stock rationalisation, this seals are comfortable to use in wide range of application as below:
