    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.

    Spiral Trac Environmental Control Device

    Install with Mechanical Seals/Packing for Effective Removal of Solids and Improved Cooling

    ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The SpiralTrac™ Environmental Controller* is an exclusive, patented throat bushing specially engineered to transform and control the internal stuffing box environment in rotating process equipment to reduce downtime and extend equipment life. With unique versions designed to work with both Chesterton mechanical seals and packing, SpiralTrac modifies the flows that exist inside rotating processing equipment:​

    • Enables particulates to be removed from the stuffing box (and away from packing or mechanical seals)
    • Permits air to evacuate the stuffing box upon flooding to retain cooling
    • Minimizes heat buildup in the stuffing box by creating circulation around seal faces.

     

    Avoid Complex Environmental Control Systems

    SpiralTrac is us​ed with a small flush or no flush in chemical service applications and is machined in the bottom to effectively drain the seal cavity.​

     

    It is offered in four configurations:

    • Split: Split ring design for easy installation
    • Adapter: For non-standard stuffing box configurations
    • Standard: Bushing style
    • Packing: For use with compression packing
