N70U & N75U (Single Acting Unbalanced Design)

Series N70U & N75U are developed for slurry and dirty media applications as per DIN 24960 specifications. 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 N70U to N75U by changing only the seal ring and the secondary seal. These seal series are conceptually designed for stock rationalization.
