- Chesterton 170 SSC/SSC Slurry Single Cartridge Seal

The Version D SpiralTrac has a unique double spiral design specifically engineered for fibrous environments. The enhanced axial flow generated by the double spiral helps remove non settling fibrous solids out of the seal cavity, keeping the seal area clean, and the seal faces cool and lubricated. As of writing, the application has been running successfully for over 2 years. That is already 4 times longer than the previous MTBF!
