    Profile

    These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F. Also known as V-rings and flingers, they protect shaft bearings by blocking dust and other contaminants while retaining lubricant. To install, stretch the seal over your shaft and press it firmly against the face plate.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    Heavy Duty Mechanical Pump Shaft Seals

    Image of Product. Front orientation. Exploded view. Contains Annotated. Shaft Seals. Heavy Duty Mechanical Pump Shaft Seals.
    Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, springs, diaphragm, and washer, and the seat is comprised of the seat and the gasket. Seal Width represents the working height, which is the compressed length when installed.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals. They have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing. Pistons require two seals—install one facing in each direction.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
    Graphite Filled—Graphite-filled seals have greater wear resistance and strength than seals without a filler.
    PTFE—PTFE seals withstand a wider range of temperatures and chemicals than UHMW 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.

    Male and Female

    Adapters Stacked with

    Five V-Rings

    Profile

    Made of PTFE, these V-ring packing seals have excellent chemical resistance and withstand a wide temperature range of -110° F to 500° F. Stack as many V-rings as you need to fill grooves in valves, pumps, and cylinders.
    Begin with a male and female adapter, then add V-rings between them to fill the space. Each V-ring adds to the sealing force; the female adapter also has a sealing edge. For a complete seal, you need male and female adapters (sold together) and at least one V-ring (sold in packs of 5).
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    Rod Wipers

    Also known as U-type wipers, these have a single lip that scrapes dirt, dust, and moisture from the rod, preventing contamination inside the cylinder.
    Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

    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.
    Viton® Fluoroelastomer Diaphragm—Viton® fluoroelastomer diaphragms resist a wider range of chemicals than Buna-N.
    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.
