The Wacker Neuson Ball Bearing is a genuine OEM component designed for PDT2, PDT3, PDI2, and PDI3 series diaphragm trash pumps. As a direct factory replacement, this bearing is built to the same specifications as the original, ensuring proper fit within the pump's drive assembly. It is compatible across a wide range of 50mm/2-inch and 75mm/3-inch Wacker Neuson diaphragm trash pump configurations, including both inline and standard models. Choosing the correct OEM part keeps your pump running at rated flow capacity and helps avoid premature wear on surrounding components.
Key Features
- OEM-Grade Load Tolerance — Manufactured to the same radial load and rotational speed tolerances as the original bearing, maintaining consistent pump drive performance across the full duty cycle.
- Drop-In Replacement — Matches the original bearing seat dimensions and interface geometry for straightforward installation without modification to the housing or shaft.
- Broad Diaphragm Pump Compatibility — Fits PDT2, PDT2A, PDT2B, PDT3, PDT3A, PDI2, PDI2A, PDI3, and PDI3A series diaphragm trash pumps from Wacker Neuson.
- Protects Drive Assembly Integrity — A worn or failed bearing allows shaft misalignment, which accelerates seal wear and can lead to diaphragm failure and pump output loss.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying full OEM part number 5000089217 for confident ordering and parts record accuracy.
A ball bearing in a diaphragm trash pump supports the rotating drive shaft that actuates the diaphragm, converting engine or motor power into the reciprocating motion that moves fluid through the pump. It carries both radial and axial loads generated during operation, keeping the shaft centered and reducing friction for smooth, efficient power transfer. When a bearing wears out, shaft play increases, placing stress on the diaphragm and seals — leading to reduced pumping output, fluid leaks, and eventually a complete loss of pump function if not addressed.
