The Wacker Neuson Bearing is a genuine OEM component designed for the PDT and PDI series diaphragm pumps, including the PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) models. Sourced directly from Wacker Neuson, this bearing matches the original specification for correct fit and function without adaptation. It is a direct replacement for units across multiple machine numbers within the PDT and PDI pump families. If your diaphragm pump is showing signs of wear or noise in the drive assembly, part is the factory-specified replacement to restore proper operation.
Key Features
- Genuine OEM Load Rating: — Manufactured to the original tolerance spec for the PDT/PDI pump drive assembly, ensuring correct load distribution and shaft alignment under operating conditions.
- Direct Drop-In Replacement: — Designed to seat into the existing bearing housing on PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) pumps without reworking the housing or shaft.
- Broad PDT/PDI Family Coverage: — A single part number covers both 2-inch and 3-inch models across the PDT and PDI diaphragm pump range, simplifying parts procurement for mixed fleets.
- Protects Drive Shaft and Pump Housing: — A worn bearing allows shaft play that accelerates wear on surrounding components; replacing it promptly preserves the integrity of the entire drive assembly.
- Verified Wacker Neuson Part Number: — Part number 5000180285 is confirmed against multiple machine numbers in the PDT/PDI series, so you can order with confidence that this is the correct bearing for your pump.
A bearing in a diaphragm pump supports the rotating drive shaft, allowing it to spin smoothly while carrying the radial and axial loads generated during pump operation. When the bearing is in good condition, the drive assembly runs quietly and the diaphragm strokes evenly, maintaining consistent flow and pressure. As the bearing wears, shaft play increases, leading to vibration, accelerated seal wear, and eventually damage to the pump housing or diaphragm — making timely replacement essential to keeping the pump performing at full capacity.
