This game-changing design reduces labor hours, minimizes maintenance costs, and improves safety.
Built for long-term performance, Chesterton split seals are crafted with high-grade materials such as carbon, silicon carbide, and chemical-resistant elastomers—offering superior resistance to wear, corrosion, and extreme temperatures. The patented, self-aligning, interlocking components ensure fast, accurate installation and consistent sealing performance.
With thousands of successful installations worldwide—including seals up to 915 mm (36") in diameter—Chesterton remains the global leader in split seal innovation.
Cartridge Seals
Chesterton cartridge seals deliver outstanding reliability and longevity, even in high-pressure, high-temperature, and corrosive conditions. They are ideal for use in pumps, mixers, agitators, and other rotating equipment across a variety of industries.
Available in single and double seal configurations, with a broad selection of materials and gland options, Chesterton seals offer the flexibility to meet your exact specifications. Their versatile designs support plantwide standardization – helping facilities reduce inventory, simplify maintenance, and streamline staff training.
Component Seals
Chesterton component seals deliver a dependable, cost-effective solution for sealing rotating equipment in both new installations and retrofit applications. Engineered to withstand corrosive chemicals, extreme pressures, and high temperatures, Chesterton component seals perform reliably even in tight installation spaces. Built with premium materials such as silicon carbide, tungsten carbide, and chemical-resistant elastomers, they offer exceptional resistance to wear, corrosion, and thermal shock.
Slurry Seals
Chesterton slurry seals are purpose-built to perform in the harshest abrasive and high-solids environments—even in applications where flush water may be limited or unavailable. Designed for durability and reliability, these seals help prevent leakage, minimize contamination, and extend equipment life in some of the most demanding industrial settings.
Gas Seals
Chesterton gas seals combine advanced, patented sealing technology with a compact, easy-to-install profiled designed to fit standard ANSI/API pumps, mixers, compressors, and blowers without modification. The exclusive In-Gland Control System (IGCS) automatically tracks process pressure to regulate barrier gas, eliminating external gas panels and optimizing gas consumption for significant cost savings.
