FOR IMMEDIATE RELEASE
June 2, 2017 - Groveland, Massachusettts: Chesterton’s Polymer Labyrinth Seal (PLS) won a bronze award in the Fluid Sealing Category for Plant Engineering’s 2016 Product of the Year Program.
PLS is a unitized, non-contacting seal designed to protect splash-lubricated bearings found in pumps, motors, gearboxes, and other rotating equipment. The unique seal is designed to eliminate fretting caused by conventional lip seals, and extends bearing and gearbox life by increasing the time between equipment repairs.
Plant Engineering's 2016 Product of the Year program consisted of 15 categories and is “a celebration of all that is new and innovative in product development.” The awards were presented to the winners at the 2017 Engineering Awards in Manufacturing dinner on Monday, April 3, 2017, hosted by both Plant Engineering and Control Engineering.
Chesterton’s Polymer Labyrinth Seal (PLS) is a patent-pending seal ideal for use as an upgrade from conventional lip seals because it reduces fretting and helps to reduce maintenance costs associated with premature bearing and gearbox failures.
Fossil Power Plant - Italy: The PLS was used to replace an elastomer radial oil seal in a hot water circulating pump (Goulds Type LX). The original seals failed prematurately with a lifetime of <3 months and caused shaft sleeve fretting. The Chesterton PLS non-contacting seal was made to size and is still working well after 9 months.
Chemical Plant - Japan: The Chesterton PLS was used to replace an elastomer radial oil seal in a process pump for splash beaing protection of pump bearing housing. The original seal had a varying, short life span. The PLS1 non-contacting seal was made to size and has existed over 14 months with virtually leak-free operation.
PLS is available in a variety of configurations to meet plant-wide equipment needs.
