The Chesterton 170L Slurry Single Cartridge Mechanical Seal is made to fit Warman AH Series pumps and is engineered to operate in harsh, heavy consistency slurry environments and eliminate costly external seal flushes in the majority of applications. The 170L is designed for sealing mineral-based process materials such as ores, limestone, coal, sugar, and phosphates. The non-clog seal utilizes a unique coil spring design in which the springs are located entirely outside the seal.
