The Wacker Neuson Flange Bolt is a genuine OEM component designed for the PT2 and PT3 series self-priming centrifugal trash pumps, including PT2, PT2H, PT2V, PT2A, PT3, PT3H, PT3V, and PT3A variants. Sourced directly from Wacker Neuson, part number carries the same specifications as the hardware installed at the factory. It serves across the full PT2 and PT3 pump lineup, making it a practical stocking item for operators and service teams running multiple pump models on site.
Key Features
- Genuine OEM Hardware Grade — Manufactured to Wacker Neuson's exact thread pitch, shank diameter, and flange bearing-surface dimensions, ensuring consistent clamping load across pump assemblies.
- Drop-In Replacement — Matches the original bolt pattern on PT2 and PT3 series pump housings; installs with standard tooling and torques to spec without modification.
- Broad PT-Series Coverage — Fits PT2, PT2H, PT2V, PT2A, PT3, PT3H, PT3V, and PT3A pump models, covering both 50mm/2-inch and 75mm/3-inch discharge configurations.
- Leak-Free Joint Integrity — The integrated flange face distributes clamping force evenly across mating surfaces, helping maintain a sealed pump assembly under continuous high-volume pumping conditions.
- Corrosion-Resistant Construction — Built to withstand exposure to water, mud, and the demanding conditions typical of dewatering and site drainage applications.
A flange bolt differs from a standard hex bolt in that it features a built-in washer-like flange beneath the head, which spreads the clamping load over a wider area on the mating surface. In centrifugal trash pump assemblies like the PT2 and PT3 series, these bolts are used to secure pump housings, volute covers, and other critical mating flanges. A worn, stripped, or missing flange bolt can allow pump casings to separate under pressure, leading to loss of prime, reduced discharge performance, or water ingress into the engine compartment. Replacing a damaged flange bolt with the correct OEM part restores the manufacturer's specified joint integrity and keeps the pump operating at full capacity.
