Component, cartridge, slurry and split designs — with sealing faces, elastomers and metal parts specified against the liquid media, the pressure and the temperature, not picked from a shelf.
Supplied as separate rotary and stationary units so the combination can be matched to the equipment. Numerous configurations are available to known engineering designs, with variations of sealing faces and elastomer specification.
A dependable, cost-effective solution for sealing rotating equipment in new installations and retrofits alike — engineered to withstand corrosive chemicals, extreme pressures and high temperatures, and to perform in tight installation spaces.
A cartridge seal is a fully assembled mechanical seal that installs quickly and removes the setting errors that cause early failure. Single cartridge seals are the general-purpose choice across water, wastewater and chemical duties.
Double cartridge seals are used where the pumped fluid is not a suitable lubricant for the sealing faces, where the liquid media is aggressive, or where atmospheric leakage is unacceptable — running a barrier or buffer fluid to the application's API plan.
Correct face specification is essential to performance, and every metal part and O-ring is specified against the duty.
The Chesterton 170 slurry seal is engineered for severe slurry environments and eliminates costly external seal flushes — reducing product dilution and water usage while increasing production rates.
Stationary springs sit outside the seal chamber, giving stable, clog-resistant performance under extreme conditions. The cartridge-style configuration simplifies installation and reduces downtime. Built from wear-resistant materials for mining, minerals processing and other slurry-intensive industries.
The Chesterton 442C cartridge split mechanical seal brings the technical advances that raise seal performance and reliability while simplifying installation — patented self-aligning, interlocking components locate fast and accurately.
Crafted from high-grade materials — carbon, silicon carbide and chemical-resistant elastomers — for superior resistance to wear, corrosion and extreme temperatures. Thousands of successful installations worldwide, including seals up to 915 mm (36″) in diameter.
Correct specification of sealing faces is essential to performance. Send us the application — liquid media, pressure, temperature and shaft size — and we will specify the seal.
