LPS-081-U/LPS-085-U & LPS-083-B/LPS-088-B
LPS-081-U/LPS-085-U & LPS-083-B/LPS-088-B series are multiple springs unbalanced/balanced Mechanical Seal developed for universal applications. It is independent of direction of rotation; torque transmission from drive collar shell to dynamic ring is done through drive pin. Their compact design permits their used in all types of centrifugal pumps and which helps in easier installation & removal. As all parts are interchangeable, one can convert this series LPS-081-U/LPS-083-B to LPS-085-U/LPS-088-B by changing only the dynamic ring, this principle is ideal for stock rationalization, this seals are comfortable to use in wide range of application as below:
