Chesterton, the world leader in split seal technology, has the largest installed base globally. Our broad experience in split sealing enables a wide array of users to improve plant efficiencies. Today, with years of proven performance, Chesterton split seals are used in more types of equipment, sealing more types of process materials.
The 442’s unique, patented adjustable gland, with captured fasteners, and automatic centering deliver unsurpassed ease of use.
Chesterton split seals are installed in all types of equipment and deliver years of reliable service.
"P" shaped spacer positions the 442 seal for easy installation.
Ball-and-socket o-rings are leak-free, without the use of adhesives. Installation video is available to demonstrate easy installation.
Chesterton was challenged by one of the world's largest refineries to improve the MTBR for mixer seals used in their Alkylation Reactor Units. Ideally, the service life of the seal would run in parallel with their 5-year turnaround cycle. Secondary issues included reducing repair costs, lowering acquisition costs and offering local seal repair. Previously a combination of Durametallic and older Chesterton seal designs were used. The Dura MX-201 cartridge seals lasted from 2-3 years causing unscheduled interruptions and impacting overall production.
The 170 Slurry Seal is engineered to Operrate in severe slurry environments, eliminating costly external seal flushes. Plant efficiency improvements are achieved with the 170 seal by reducing product dilution and increasing production rates while meeting environmental concerns. The abrasive slurry operating environment along with low water dilution requirements creates an aggressive sealing challenge. The 170 meets this challenge by integrating multiple high performance slurry design features. These features combined with Chesterton’s local service will deliver unparalleled slurry handling performance levels.
Self Centering Lock Ring Ensures Reliability
The Patented Prcise for correct face mating and sustainable sealing. Cloverleaf 3 point Contact ensures concentricity to the shft. Faces start out square and stay square to prevent the instrusion of contaminats of abrasives. also, consistant face squareness reduces opportunities for fluid leakage and uneven wear
Many Common conditions create dynamically chnaging stresses on the seal faces. Consider changes in tempratures of pressure, Fluid phase changes, or water hammer. commnface geometries distortat the mating surface stresses in the body of the seal ring, away from the critical face mating surfaces. faces stay flat, preventing intrusion of contaiminants or fluid leakage for long term reliability
Highly Effective emissions control
The advanced design of the 155 and ability to keep faces square and flat ensures superior emissions control capability. the 155 has proven in independent tests to be able to meet or exceed the most stringent USA emissions standarts. of course for total emissions control or hazardous fluids, use Chesterton ne generation dual seals
All wearing parts, seal faces, O-rings, screws and springs are replaceable at low cost, making in-plant rebuilding simple and economical. Parts being replaced can be crushed and bagged for environmentally safe disposals
