  • DESCRIPTION

    HOMA AMX644-260/20P/C Repair Kit – 45mm Mechanical Seals

    The HOMA AMX644-260/20P/C repair kit is a direct-fit rebuild kit for the HOMA AMX644-260/20P/C submersible pump — 45 mm upper and lower HOMA-special mechanical seals in silicon carbide with Viton secondary seals, supplied with the Buna-N O-ring set including the O-ring seats for both seals. Built to OEM-equivalent standards or higher.

    What’s included

    • 45mm OEM equivalent Homa special mechanical seal (upper) – Silicon carbide / silicon carbide (SiC/SiC), Viton (FKM)

    • 45mm OEM equivalent Homa special mechanical seal (lower) – Silicon carbide / silicon carbide (SiC/SiC), Viton (FKM)

    • Buna-N O-ring kit

    Application

    The AMX644-260/20P/C is a HOMA AMX-series submersible wastewater pump, and the upper and lower seal pair is what keeps the motor dry once the pump is back in service. Silicon carbide running against silicon carbide is the face combination for water carrying grit — it takes the abrasive load that grooves a carbon face, which is why HOMA specifies SiC on both sides as standard. Viton secondary seals cover the temperature and chemical range of municipal and industrial duty. The seals in this kit are the HOMA special design, not a standard-seat seal, and the kit includes the O-ring seats for both. Built to OEM-equivalent standards or higher.

    Compatibility:

    • Pump compatibility: Homa AMX644-260/20P/C

    • Motor compatibility: N/A (motor model unknown)

    Fitment

    Fits: HOMA AMX644-260/20P/C. HOMA uses multiple seal designs that can share the same shaft size — match by the full model number from the pump nameplate and confirm seat style and thickness before ordering. Not sure which you have? Text a photo of the nameplate and the old seal to 561-414-1046 and we’ll match it. No purchase required.
