Effective against product and gas interchange, Guardian Seal™ consists of multiple elastomer seals stretched over rotating screw conveyor shaft. Seals face both inward and outward, and gap in-between is filled with grease through remote zerk. As seals wear, they continue to conform to shaft to extend seal life. Self-adjustable product, with bolt on installation, requires occasional greasing and handles shaft run-out and thermal expansion.
