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 hel​ps 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.​ Features & Benefits High-performance, non-contact design eliminates fretting caused by lip seals Keeps lubrication in and seals out external contamination Unitized design and durable, non-sparking material provide easy, reliable installation Available in a variety of configurations to meet plant-wide equipment needs Same-day shipment availability, minimizing downtime and associated costs Standard sizes available for popular equipment; custom sizes available upon request IP56 (third party certification) designed to be resistant to dust and water
