Slurry Single Cartridge Seal
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 innovative, non-clog seal utilizes a unique coil spring design in which the springs are located entirely outside the product. The 170L uses a single clamping screw which simplifies seal removal in sticky or viscous fluids or where solids clog up the set screws. The 170L has large clearance and rugged components designed to resist the effects of heavy slurry environments. Plant optimization can be achieved through reduced product dilution and higher production rates.
- Runs longer in heavy abrasive slurries without the need for flush or quench water
- Stationary springs located outside the seal for maximum reliability
- Clamp ring available for ease of installation
