The Wacker Neuson 5200021763 Drain Valve is a genuine OEM component designed for the APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T pump series, including standard, cold weather, electric brake, surge brake, and skid-mounted configurations. As a factory-sourced part, the 5200021763 is manufactured to the exact specifications Wacker Neuson engineers built into these towable pump units, ensuring a direct, correct-fitting replacement every time. This drain valve serves a critical role in fluid management for the APT series, making it an essential service item for routine maintenance and winterization procedures. Verify your machine model against the fitment list to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this drain valve is manufactured to the same material and dimensional tolerances as the original component installed at the factory.
- Broad APT Series Coverage — Fits the full APT4S, APT4T, APT6S, APT6T, APT8S, and APT8T pump lineup, including standard and cold weather variants with electric brake or surge brake configurations.
- Drop-In Service Replacement — Designed to thread or seat into the existing drain port without modification, keeping service time to a minimum during scheduled maintenance or winterization.
- Critical for Freeze Protection — A functioning drain valve allows complete fluid evacuation from the pump system, preventing freeze damage in cold weather operation — particularly important for CW-designated models.
- Prevents Fluid Loss and Contamination — A worn or failed drain valve can result in uncontrolled fluid leakage or an inability to fully drain the system, compromising both pump performance and fluid integrity.
A drain valve controls the release of fluid from a closed system within the pump, allowing operators to fully evacuate liquid from the pump body and associated plumbing during maintenance, storage, or cold weather preparation. On towable pump units like the APT series, a properly sealing drain valve is essential to protect internal pump components from freeze damage and to facilitate clean, controlled fluid removal during servicing. When the drain valve fails — through thread wear, seal degradation, or cracking — it can cause unintended leaks during operation or prevent complete drainage, leaving the system vulnerable to freeze damage or contamination.
