The Wacker Neuson 5100044493 is a genuine OEM Flange Bolt designed for the PT3A, PT3A(I), PT4A, and PT4A(I) series self-priming centrifugal trash pumps. As a factory-sourced component, it meets the original design specifications set by Wacker Neuson for these pump models. Verified fitment across multiple PT-series configurations makes the 5100044493 a straightforward, confidence-inspiring replacement when servicing your pump's flanged connections.
Key Features
- Genuine OEM Integrity — Sourced directly from Wacker Neuson, this flange bolt is manufactured to the exact thread specification, shank diameter, and head geometry required for flanged joints on PT-series trash pumps.
- Drop-In Replacement — Matches the original bolt pattern and seating surface, allowing straightforward installation without rework or fitting adjustments at the flange joint.
- Broad PT-Series Compatibility — Confirmed fitment for PT3A, PT3A(I), PT4A, and PT4A(I) pump models, covering both standard and indirect-drive configurations within the Wacker Neuson trash pump lineup.
- Maintains Pump Integrity Under Pressure — A correctly torqued flange bolt keeps flanged housings and covers sealed tight. A stripped, corroded, or under-spec bolt risks fluid leaks, pressure loss, and pump housing damage during operation.
- Critical Fastener for Fluid-Carrying Joints — On pumps handling water, slurry, and debris-laden fluids, flange fasteners are subject to vibration and thermal cycling. Using the correct OEM bolt protects the sealing surface and prevents joint failure in demanding site conditions.
A flange bolt secures the mating faces of flanged pump housings, covers, and pipe connections, holding them together under the operating pressures and vibration generated by a running trash pump. It works in combination with a gasket or O-ring to create a leak-free seal at the joint — if the bolt is the wrong grade, thread pitch, or length, that seal is compromised. A missing, damaged, or incorrect flange bolt can result in fluid leaks at the connection point, reduced pump efficiency, and potential damage to surrounding components, making it one of the smaller fasteners that carries an outsized responsibility in pump performance.
