  • Chesterton 442C Split Cartridge Seal

    Chesterton is the world leader in design innovation of split seals. Our innovative split seals have been used to seal thousands of process-critical pieces of rotating equipment with exceptional​​ ​results and many years of leak-free operations.

     

    Chesterton was the first company to offer commercially-viable split seals for plant-wide use, which revolutionized pump sealing across industries. Since that time, we’ve launched a number of innovative split seal designs now used as a standard by companies around the globe.​ We offer shaft diameters ranging from 25-914​ mm (1-36 in.)​

  • Chesterton DualPac® 2212 Packing

    A reliable sealing solution can save you both time and money on your pump operation. Traditional braided pump packing requires frequent gland adjustments and often burns out quickly, especially under high speeds. This results in packing failure and equipment damage.

    Chesterton® DualPac 2212 is created using ​our patented DualPac Technology,  which combines a burn-resistant material on the packing’s shaft side with a highly resilient outer fiber. This formulation creates a unique, long-lasting packing that ​uses the gland load more efficiently and achieves a reliable and quicker break-in period.  This ability keeps the packing internally loaded against the rotating member while, at the same time, resisting burning and shaft scoring. DualPac 2212 gives users peace of mind in the toughest sealing applications.

    ​DualPac Technology Advantages

    • Significantly fewer gland adjustments than traditional packing
    • Simplifies your inventory: you can use the same packing for end rings and sealing rings
    • Better utilization of gland load in sealing configuration
    • Minimizes shaft scoring
    • Requires less overall maintenance​​​

  • Chesterton NSF 61 Seals

    Chesterton Expands NSF 61 Certification to All Single Cartridge and Split Mechanical Seals

    To meet the growing demand for certified drinking water supplies, Chesterton has expanded its offering of NSF 61 certified mechanical seals to include all its single cartridge seals as well as split seals.

     

    Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI/CAN 61 sets health effects criteria for many water system components. The majority of water treatment or distribution products in North America are now required to comply with NSF/ANSI/CAN 61: Drinking Water System Components – Health Effects by governmental agencies that regulate drinking water supplies.

     

    Previously, Chesterton’s NSF products were limited to the 155 Single Cartridge Seal and the Chesterton 442 with RSC faces. The company recently received approval for ALL Chesterton single cartridge seals as well as its flagship Chesterton 442 and 442C split seals.

     

    The certifiable seal configurations are as follows:

    • 155, 150, S10 (Seal Faces: CB/SSC EP, SSC/SSC EP) including variants
    • 442C, 442 (Seal Faces: CB/RSC EP, RSC/RSC/EP) including variants

     

    Chesterton also offers an industrial coating NSF 61 certified product, ARC S1PW​, which protects pipes and other structures against erosion, corrosion, and chemical attack.
