    DETAILS & SPECIFICATIONS

    Product Detail

    +
    The GW L9 cartridge seal offers a pre‑assembled, ready‑to‑install solution for external sealing applications. Its engineered design incorporates a hydraulically balanced rotating face that reduces heat and wear, extending seal life and lowering power consumption. All wetted components are constructed from non‑metallic materials, providing enhanced resistance to corrosion and chemical attack.

    This unit is manufactured to match the dimensional and performance specifications of the AES CS cartridge seal, ensuring full interchangeability in compatible seal cavities. Suitable for pumps, mixers, and other rotating equipment, the GW L9 is ideal for maintenance upgrades and OEM replacements where reliability and ease of installation are critical.

    *Installation note: Confirm equipment shaft size and seal cavity dimensions before fitting. Use proper handling procedures to avoid seal face damage.
