The Wacker Neuson is a genuine OEM Bolt with Washer Kit (12) 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 kit delivers the exact hardware specification required for proper pump assembly and service. Each kit includes twelve bolt and washer sets, giving you everything needed to complete a full fastener replacement in a single order. Confirm your model number before ordering to ensure a correct application match.
Key Features
- Hardware-Grade OEM Specification — Manufactured to Wacker Neuson's exact thread pitch, shank diameter, and washer bearing-surface dimensions, so fastener preload and clamp force are correct at every joint.
- Complete Kit of 12 — Supplies the full count of bolt-and-washer sets needed for a single service interval, eliminating the risk of a partial fastener replacement that can cause uneven clamping.
- Direct-Fit for PDT and PDI Diaphragm Pump Families — Verified fit across the PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) pump models with no rework or hardware substitution required.
- Diaphragm Seal Integrity — Properly torqued OEM-spec bolts maintain even compression across the diaphragm housing, which is critical for maintaining suction performance and preventing bypass leaks during pump operation.
- Genuine OEM Part — Part number 5000180277 is an authentic Wacker Neuson component, ensuring traceability and correct fitment for professional pump maintenance and service documentation.
In a diaphragm pump, the bolts and washers in this kit secure the diaphragm housing halves and cover plates together, creating the clamped seal that allows the diaphragm to flex and generate suction and discharge pressure. If these fasteners are worn, stretched, or improperly seated, the clamping load across the diaphragm perimeter becomes uneven, which can cause the diaphragm to leak, lose suction, or fail prematurely. Replacing the full set with correctly specified hardware ensures the pump maintains its rated flow and discharge performance through its next full service cycle.
