Description

Multi spring unit unbalanced double Mechanical Seals for clear & non-corrosive liquids. It is independent of direction of rotation, this design uniform force over the seal faces enhance its life. These seals can be offered in balanced and unbalanced configuration, these seals are in three type of arrangement, Back to Back, Face to Face & Tandem arrangement 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 rationalization, this seals are comfortable to use in wide range of application as below:
