Seal series N70B & N75B are developed for high pressure slurry and dirty media applications to meet 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 N70B to N75B by changing only the seal ring and the secondary seal. These seal series are conceptually designed for stock rationalization.
