During normal operation, municipal wastewater like many plants utilize large rotating equipment to move fluid (wastewater) throughout various processes within each treatment plant.  Large equipment repair and ultimately disassembly leads to reduced equipment availability, additional labor needs, lifting & rigging, incidental component replacement, and disruption of nearby plant and services, just to mention a few challenges faced.  These critical equipment disassembly costs can be dramatically reduced with the A. W. Chesterton 442C XL Cartridge Mechanical Seal advantages.  This seal delivers ease of installation and use, without equipment disassembly. In customer terms, the A. W. Chesterton 442C XL improves reliability and reduces maintenance cost.

A.W. Chesterton’s patented 442C Split Cartridge Seal design incorporates features that protect the precision lapped, split faces, incorporates an adjustable gland that makes for easy adjustment to suit your equipment bolting pattern, and does not require the pump to be disassembled to maintain.  Since the pump remains assembled during the seal installation, the pump remains aligned.  This is a double feature, eliminating pump disassembly time and reducing the complex startups process.

As of this blog, A.W. Chesterton is now supplying this technology in a much larger range of sizes.  The latest developments have raised the bar and the range significantly to fit rotating equipment shafts from 5.00” up to 7.75”.  This increases the application opportunity to reduce down time and increases productivity.

This new size range with the 442C platform is finding success and continued proven reliability in many industries and applications. A. W. Chesterton 442C XL Cartridge Split Mechanical Seals assures the plant personnel time-savings and a reliable sealing solution. With over 10,000 Chesterton split seals installed and operating globally, you can be confident in implementing this technology.
