    Item #SH-19B33MMKRTE80-251

    KSB Amarex KRTE 80-251 Pump Repair Kit

    A direct-fit service kit for the KSB Amarex KRTE 80-251/164XG submersible pump. Built to OEM-equivalent standards or higher.

    What’s included:

    • (2) mechanical seals, 33mm — Silicon Carbide / Silicon Carbide faces, Viton (FKM) elastomers

    • O-ring kit — complete, matched to the KRTE 80-251/164XG

    Application:

    • Brand: KSB

    • Pump model: Amarex KRTE 80-251/164XG

    • Series: Amarex KRT / KRTE submersible motor pump

    An Amarex KRT works in a wet well moving raw sewage and stormwater, so the liquid crossing the seal faces carries grit and rag continuously, and the pump runs unattended for long stretches between services. Silicon carbide against silicon carbide resists that abrasion, runs cooler under marginal lubrication, and tolerates the brief dry-running that comes with a falling wet well. The Viton (FKM) elastomers hold up against the heat and the fats, oils and treatment chemistry that come with the same work.

    Replace both seals at the same service. The upper seal is what stands between a failed lower seal and a flooded motor, and it has been working the whole time the lower one has.

    Fitment

    Confirm the type and serial number on the pump nameplate before ordering. Not sure? Send a photo of the nameplate and the old seals to info@sealhouseusa.com, or call or text 561-414-1046 — our seal specialists will match it. No purchase required.

    Application:

    • Brand: KSB

    • Pump model: Amarex KRTK 150-401/506XG-S

    • Series: Amarex KRT / KRTK vertical single-stage submersible motor pump

    An Amarex KRT sits in a wet well moving raw sewage and stormwater, so the liquid crossing the faces carries grit and rag continuously, and the pump runs unattended for long stretches between services. Two hard faces resist that abrasion, run cooler under marginal lubrication, and tolerate the brief dry-running that comes with a falling wet well. The Viton (FKM) elastomers hold up against the heat and the fats, oils and treatment chemistry that come with the same work.
