The Multiquip 020PX400023 Companion Flange PX-400 is a genuine OEM component designed for PX400 series submersible pumps. Sourced directly from Multiquip, this flange is manufactured to the exact specifications required for correct installation and a leak-free connection on PX400 equipment. Genuine OEM construction means you are installing the same part that left the factory — no guesswork on fit, thread pattern, or material grade. If you are maintaining or rebuilding a PX400 submersible pump, this is the correct companion flange for the job.
Key Features
- OEM-Grade Material Construction — Built to the same dimensional and material standards as the original flange, ensuring proper sealing surface integrity under submersible pump operating pressures.
- Direct-Install Compatibility — Engineered to align precisely with the PX400 pump discharge assembly, allowing straightforward bolt-up installation without rework or shimming.
- Confirmed PX400 Fitment — Verified for use on Multiquip PX400 polyurethane impeller submersible pumps — order with confidence for this specific model family.
- Maintains Discharge Integrity — A worn or damaged companion flange can cause flow loss, misalignment at the discharge connection, and accelerated seal wear. This replacement restores a secure, properly aligned joint.
- Genuine Multiquip OEM Part — Supplied as an authorized Multiquip replacement, ensuring this part meets the performance expectations of the original design rather than a generically adapted alternative.
The companion flange on a submersible pump serves as the structural and sealing interface between the pump's discharge outlet and the connected piping or hose assembly. It holds the discharge connection rigid and leak-free under continuous pumping loads, which is especially critical in submersible applications where access for mid-job repairs is limited. When a companion flange cracks, corrodes, or loses its seating surface, the discharge joint can weep or fail under pressure, compromising pump output and potentially damaging downstream piping connections.
