    Seal with Retainer

    and Straight Spring

    For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. They come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
    Buna-N Diaphragm—Buna-N diaphragms resist grease and a wide range of oils.
    EPDM Diaphragm—EPDM diaphragms are more resistant to water and steam than Buna-N and Viton® fluoroelastomer, but aren’t as resistant to oils and chemicals.
    Viton® Fluoroelastomer Diaphragm—Viton® fluoroelastomer diaphragms resist a wider range of chemicals than Buna-N.
    Buna-N Gasket—Buna-N gaskets resist grease and a wide range of oils.
    Viton® Fluoroelastomer Gasket—Viton® fluoroelastomer gaskets resist a wider range of chemicals than Buna-N.
    Carbon Washer—Carbon washers are for use with clean liquids.
    Silicon Carbide Washer—Silicon carbide washers have a hard surface that resists scratching, so they can be used with liquids that contain abrasives.
    Cannot Be Sold Outside North America—Products cannot be sold outside North America due to restrictions.

    Mechanical Pump Shaft Seals

    Image of Product. Front orientation. Exploded view. Contains Annotated. Shaft Seals. Mechanical Pump Shaft Seals.
    Commonly used in well, sump, and displacement pumps, these seals have a two-piece spring-loaded design that keeps the sealing surfaces in contact as the material wears. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
    Buna-N Diaphragm—Buna-N diaphragms resist grease and a wide range of oils.
    Viton® Fluoroelastomer Diaphragm—Viton® fluoroelastomer diaphragms resist a wider range of chemicals than Buna-N.
    Buna-N Gasket—Buna-N gaskets resist grease and a wide range of oils.
    Viton® Fluoroelastomer Gasket—Viton® fluoroelastomer gaskets resist a wider range of chemicals than Buna-N.
    Cannot Be Sold Outside North America—Products cannot be sold outside North America due to restrictions.

    Narrow-Profile Mechanical Pump Shaft Seals with Extended Spring

    Image of Product. Front orientation. Exploded view. Contains Annotated. Shaft Seals. Narrow-Profile Mechanical Pump Shaft Seals with Extended Spring.
    With a smaller seal OD than standard seals, these seals have an extended spring that accommodates variations in seal cavity length. They're used in waste water, boiler feed, and compressor pumps. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    Cartridge Mechanical Shaft Seals

    Image of Product. Front orientation. Exploded view. Shaft Seals. Cartridge Mechanical Shaft Seals.
    Install these seals faster and with less technical expertise than other mechanical shaft seals that come in two pieces. They come with their seal and seat already assembled. All have a carbon washer that is self-lubricating. However, this means their washer is too soft to be used with abrasive liquids and liquids with harsh additives.
    Fluoroelastomer Diaphragm—Seals with a fluoroelastomer diaphragm can be used with a wider range of chemicals than EPDM diaphragms, including benzene, butyl alcohol, and fuels.
    EPDM Diaphragm—Seals with an EPDM diaphragm won’t break down from exposure to water and steam. However, they are for use with fewer chemicals.

    Mechanical Pump Shaft Seals with Compact Spring

    Image of Product. Front orientation. Exploded view. Contains Annotated. Shaft Seals. Mechanical Pump Shaft Seals with Compact Spring.
    Built for small circulation and dispensing pumps, these seals have short springs. The spring-loaded design keeps the sealing surfaces in contact as the material wears. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. Seal Width represents the working height, which is the compressed length when installed. The seat is comprised of the seat and the gasket.
    Note: Maximum performance values cannot be achieved simultaneously. For example, speed is affected by pressure, temperature, and other operating conditions.
    Buna-N Diaphragm—Buna-N diaphragms resist grease and a wide range of oils.
    Viton® Fluoroelastomer Diaphragm—Viton® fluoroelastomer diaphragms resist a wider range of chemicals than Buna-N.
    Buna-N Gasket—Buna-N gaskets resist grease and a wide range of oils.
    Viton® Fluoroelastomer Gasket—Viton® fluoroelastomer gaskets resist a wider range of chemicals than Buna-N.
