225
Reliable Dual Seal for High-Performance, Low-Emission Applications
The Chesterton 225 is a dual cartridge seal engineered for critical sealing in tough process environments, including those requiring reduced emissions and enhanced containment. With a non-fretting design, robust construction, and stable dual-face configuration, the 225 provides long-lasting reliability in pumps, mixers, and rotating equipment. Its modular design fits standard ANSI and ISO equipment, making installation and maintenance straightforward. Ideal for chemical, pulp and paper, and other demanding industries, the 225 delivers strong performance, even under fluctuating pressures and temperatures.
