The Wacker Neuson is a genuine OEM 4 Bspt Flange designed for PSC-series submersible pumps, including the PSC42203, PSC43703, PSC42303EX, and PSC43803EX. As a factory-sourced component, this flange matches the original discharge connection geometry, ensuring a proper seal and secure pipe interface at the pump outlet. Buyers can order with confidence knowing part number is the correct OEM-specified fitting for these Wacker Neuson submersible pump models.
Key Features
- OEM-Matched Thread Form — Manufactured to the exact BSPT (British Standard Pipe Taper) thread specification of the original, so the connection seals correctly without the risk of cross-threading or leakage.
- Direct Drop-In Replacement — Installs into the same discharge port position as the factory flange, requiring only standard pipe fittings and thread sealant already used during initial setup.
- Confirmed PSC-Series Fitment — Verified for the PSC42203, PSC43703, PSC42303EX, and PSC43803EX submersible pump models, covering both standard and EX-rated variants in the lineup.
- Leak-Free Discharge Connection — A correctly seated flange maintains full discharge pressure at the pump outlet; a worn or damaged flange can cause pressure loss and water ingress at the connection point.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this component meets the same material and dimensional tolerances as the part it replaces, preserving pump output performance.
The discharge flange on a submersible pump serves as the threaded or flanged interface between the pump body and the outlet piping that carries water away from the source. It must maintain a pressure-tight seal under continuous pumping load — any crack, corrosion, or thread damage on this fitting will cause water to bypass the discharge line, reducing pump efficiency and potentially flooding the installation area. Replacing a worn 4 Bspt Flange with a correctly specified OEM part restores the integrity of the discharge connection and allows the pump to move water at its rated flow and head capacity.
