The Wacker Neuson Pump Base is a genuine OEM component designed for the PDT2A, PDT2, PDI2A(I), PDT3A, PDI3A, and PDI3A(I) diaphragm pump series. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material specifications of the original, ensuring a correct installation without rework or modification. It fits across multiple PDT and PDI series pump models, making it a versatile stocking part for operators and service technicians running Wacker Neuson diaphragm pumps on their sites. When your pump base is cracked, worn, or damaged, replacing it with the genuine restores the structural foundation of the pump assembly.
Key Features
- Genuine OEM Structural Integrity — Cast and finished to Wacker Neuson's original material specification, providing the load-bearing strength and dimensional accuracy the diaphragm pump assembly depends on.
- Direct Bolt-On Replacement — Matches the original mounting pattern and interface surfaces on PDT and PDI series pumps, so the assembly seats correctly without shimming or rework.
- Broad Diaphragm Pump Compatibility — Confirmed fit across PDT2A, PDT2, PDI2A(I), PDT3A, PDI3A, and PDI3A(I) models, covering both 2-inch and 3-inch discharge diaphragm pump variants.
- Restores Full Pump Alignment — A compromised pump base causes misalignment of internal components and mounting instability; replacing it with part 5000179864 re-establishes correct component alignment throughout the pump.
- Verified Wacker Neuson Part Number — Part number 5000179864 is a genuine Wacker Neuson reference, so you can order with confidence that the part matches your machine's build specification.
The pump base forms the structural foundation of a Wacker Neuson diaphragm pump, providing the rigid mounting platform that locates and supports the pump's internal diaphragm mechanism, valve housing, and drive components. It keeps all mating parts correctly aligned during operation, which is critical for maintaining consistent fluid displacement and preventing premature wear on seals and valves. When the pump base is cracked, corroded, or structurally compromised, the entire pump assembly loses its geometric reference point — leading to fluid leaks, vibration, and accelerated failure of surrounding components.
