170 Slurry Seal
Released for testing in July 2009, the 170 Slurry Seal has springs entirely outside the seal to prevent clogging. The seal faces are loaded through an innovative loading mechanism called the pressure plate. The springs are viewed externally and can be cleaned if required. Chesterton also included larger springs into the design to also minimize clogging.
