70U & 75U (Single Acting Unbalanced Design)

Series 70U & 75U are developed for slurry and dirty media applications. These seals are designed to avoiding clogging and hang-up by using a single helical coil spring to provide better service life in slurry applications.

Its simple design makes it easy for installation and maintenance. As all parts are interchangeable, one can convert 70U to 75U by changing only the seal ring and the secondary seal. These seal series are conceptually designed for stock rationalization.
