The Wacker Neuson 5200021770 Flange Complete is a genuine OEM component designed for the APT6S, APT6T, APT8S, and APT8T series submersible pumps. As a direct OEM replacement, part 5200021770 is sourced from Wacker Neuson and built to the same specifications as the original, ensuring a proper seal and correct alignment at the pump connection point. This flange assembly covers the full range of APT6 and APT8 configurations, including skid-mounted, surge brake, electric brake, and cold weather variants. When you need to restore your pump to full working condition, the 5200021770 is the exact part the machine was built with.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original dimensional and material tolerances, ensuring the flange seats and seals correctly under pump operating pressures.
- Direct Bolt-On Replacement — Matches the original mounting pattern and port dimensions for a straightforward swap with no rework required at the connection interface.
- Broad APT Series Compatibility — Fits APT6S, APT6T, APT8S, and APT8T pumps across standard, surge brake, electric brake, and cold weather configurations.
- Maintains Pump Integrity — A correctly fitted flange prevents leakage at the discharge connection, keeping flow rates and system pressure where they need to be for effective water removal.
- Verified Part Number — Ordering by Wacker Neuson part number 5200021770 confirms you are receiving the correct assembly for your specific APT pump model.
The flange complete serves as the structural and sealing interface between the pump body and the discharge line. It holds the connection point rigid and leak-free, allowing the pump to move water efficiently without pressure loss at the joint. When a flange is cracked, corroded, or improperly seated, the pump loses discharge efficiency and can introduce air into the line — degrading performance and, in severe cases, causing the pump to run dry and overheat.
