    Rod Installation

    Piston Installation

    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.
    UHMW Polyethylene—UHMW seals are good for sealing out water and hydraulic fluid in environments where chemicals and high temperatures are not a concern.

    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.
