LPS-061-U/LPS-065-U & LPS-071-B/LPS-075-B
LPS-061-U /LPS-065-U & LPS-071-B/LPS-075-B series are 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 LPS-061-U/LPS-071-B to LPS-065-U/LPS-075-B 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:
