The Wacker Neuson 5200020014 Flange is a genuine OEM component designed for APT4S and APT4T series self-priming pumps. As a direct factory replacement, this flange is built to the exact material and dimensional standards required for proper sealing and connection integrity within the pump assembly. It is confirmed to fit multiple APT4S and APT4T configurations, including standard, electric brake, surge brake, and Cold Weather variants. Sourcing the correct OEM flange by part number 5200020014 ensures the connection point performs as intended across the full range of compatible pump models.
Key Features
- Genuine OEM Material Integrity — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the flange seats correctly and maintains a leak-free connection under pump operating pressures.
- Drop-In Replacement — Engineered to match the original mounting pattern and interface, allowing straightforward installation without reworking adjacent fittings or housing components.
- Broad APT Series Fitment — Compatible with APT4S Pump with Skid, APT4T Pump with Electric Brake, APT4T Pump with Surge Brake, and all corresponding Cold Weather variants.
- Maintains Pump Flow Efficiency — A correctly fitted flange preserves tight connection integrity at the pump inlet or outlet; a damaged or worn flange can cause pressure loss, leaks, and reduced discharge performance.
- Verified OEM Part Number — Part number 5200020014 is the factory-issued reference for this flange, eliminating guesswork when cross-referencing against your pump's parts diagram.
A flange is a rigid connecting component that joins two sections of a piping or pump assembly — typically the pump body to an inlet or discharge line — and creates a secure, pressure-rated seal when properly torqued. In a self-priming pump like the APT4S and APT4T, the flange plays a critical role in keeping the fluid path closed so the pump can build and maintain the suction necessary to prime itself and move water or other liquids efficiently. When a flange cracks, warps, or corrodes, it breaks the seal, introduces air into the system, and can cause the pump to lose prime, reducing output or preventing the unit from operating altogether.
