170L Slurry Cartridge Seal for Warman AH Pumps

Designed to fit Warman AH series pumps

Engineered to operate in harsh, heavy consistency slurry environments and eliminate costly external seal flushes in the majority of applications.

Chesterton 170L is designed for sealing mineral-based process materials such as ores, limestone, coal, sugar, and phosphates.  The innovative, non-clog seal uses a unique coil spring design in which the springs are located entirely outside the seal.  It is engineered to fit Warman AH series pumps without modification.
