Unitized, Non-Contacting Seal for Bearing Protection
Bronze Award Winner: Plant Engineering's 2016 Product of the Year Award in the Fluid Handling category
Made from Chesterton’s proprietary polymer material technology, the Chesterton, patent-pending Polymer Labyrinth Seal (PLS) is a non-contact bearing seal designed to provide protection for pumps, motors, gearboxes, and other rotating equipment in splash applications. The unique design eliminates fretting caused by conventional lip seals, and helps increase bearing and gearbox life by extending the mean time between equipment repairs.
The design also incorporates a built-in valve, activated by shaft rotation, which engages during shutdown periods to create a positive seal during idle time—blocking the ingress of external contaminants from entering the housing.
Available with same-day shipment to minimize downtime and associated costs.
