The Wacker Neuson 5200021767 Flange Complete is a genuine OEM component designed for the APT4S and APT4T submersible pump series. This includes compatibility across cold weather, electric brake, and surge brake configurations, covering the full range of APT4S and APT4T variants. As a direct OEM replacement sourced through authorized Wacker Neuson channels, the 5200021767 is manufactured to the same standards as the original part it replaces. Confirm your machine's model number before ordering to ensure proper fitment.
Key Features
- Genuine OEM Construction: — Manufactured to exact material and dimensional specifications for this flange connection point, ensuring consistent sealing performance under pump operating pressures.
- Drop-In Replacement: — Matches the original mounting pattern and port geometry of the APT4S and APT4T pump series for a straightforward swap with existing hardware.
- Broad APT-Series Coverage: — Fits APT4S Pump with Skid, APT4S Cold Weather, APT4T Electric Brake, APT4T Surge Brake, and both cold weather variants of the APT4T line.
- Maintains Pump Integrity: — A correctly fitted flange maintains the sealed flow path through the pump assembly; a worn or cracked flange can lead to leaks, pressure loss, and pump inefficiency.
- Fuel and Fluid System Safety: — Proper flange sealing is critical to preventing uncontrolled fluid escape at connection points, which is especially important in cold weather and high-demand pumping applications.
A flange on a submersible pump serves as the structural and sealing interface between major pump components or between the pump and its discharge piping. It holds adjoining sections together under pressure and ensures that fluid moves through the intended flow path without leaking at the joint. When a flange cracks, warps, or loses its sealing surface — whether from corrosion, impact, or thermal cycling in cold weather use — the pump can lose prime, drop output pressure, or allow fluid to escape at the connection point, interrupting the pumping operation entirely.
