The Wacker Neuson is a genuine OEM Flange Bolt designed for the PDT and PDI series diaphragm pumps. As a direct OEM replacement sourced through the Wacker Neuson parts program, this flange bolt meets the exact specifications required for proper flange sealing and structural integrity across the pump assembly. Compatible models include the PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) — covering both 2-inch and 3-inch diaphragm pump variants. Having the correct replacement on hand keeps your pump running at full capacity with no compromise to the flanged joint.
Key Features
- OEM Thread and Grade Compliance — Genuine Wacker Neuson hardware engineered to the correct thread pitch, shank length, and torque specification required at pump flange connections.
- Drop-In Replacement — Matches the original bolt pattern and head geometry, allowing straightforward installation at the pump flange without any modification to the housing or mating surfaces.
- Broad PDT and PDI Series Coverage — Fits PDT2A, PDT2, PDT3A, PDT3, PDI2A(I), PDI3A, and PDI3A(I) diaphragm pump models across multiple machine number variants.
- Flange Joint Integrity — Maintains the clamping load needed to keep pump flanges sealed under operating pressure; a worn or incorrect bolt risks flange leakage and loss of prime.
- Genuine OEM Part — Supplied directly through the Wacker Neuson OEM parts program, ensuring the hardware grade and dimensional accuracy match the original pump build specification.
A flange bolt secures the bolted joints that connect pump housings, inlet and outlet flanges, and other mating surfaces within the diaphragm pump assembly. By clamping these surfaces together under the correct torque, the bolt compresses the sealing interfaces and prevents fluid from escaping under pressure. When a flange bolt stretches, corrodes, or is replaced with an incorrect grade, the clamping force across the joint drops, which can lead to seepage, loss of prime, or pump body damage during operation.
