Chesterton 170L Slurry Cartridge Single Seal

Chesterton 170L Slurry Cartridge Single Seal
Designed to fit Warman® AH® series pumps

​​​​​​​​​​​​​​​​​​​​​​E​ngineered 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.

The 170L uses a single clamping screw which simplifies seal removal in sticky or viscous fluids or where solids clog up the set screws. This seal has large clearance and rugged components designed to resist the effects of heavy slurry environments.
