The Wacker Neuson M5 Nut is a genuine OEM fastener designed for the PS2, PS3, and PSA2 series submersible pumps. Sourced directly from Wacker Neuson, this nut meets the original design specification for thread pitch, material grade, and dimensional tolerance — so it installs exactly as the factory intended. It covers a broad range of PS-series configurations including the PS2-500, PS2-800, PS2-1503, PS3-1503, PS2-2203, PS3-2203, PSA2-500, and PSA2-800 models across multiple voltage variants. When you order by part number, you can be confident you are receiving the correct fastener for your machine.
Key Features
- Correct Thread Specification — M5 thread form matches the original fastener exactly, ensuring proper torque retention and a secure connection without the risk of cross-threading or loosening under pump vibration.
- Genuine OEM Part — Manufactured to Wacker Neuson's original design standards, this nut carries the same material grade and dimensional profile as the hardware installed at the factory.
- Broad PS-Series Compatibility — Fits PS2, PS3, and PSA2 submersible pump families across a wide range of voltage configurations (220V, 230V, 400V, 440V, and 575V variants), making it a versatile stocking fastener for pump service.
- Maintains Structural Integrity — A correctly specified nut keeps pump housings, motor covers, and brackets properly secured; a worn, stripped, or incorrect fastener can allow components to shift under load and accelerate seal or bearing wear.
- Direct Drop-In Replacement — Matches the original installation point without rework, keeping pump service straightforward and efficient.
The M5 Nut is a metric fastener used to secure internal and external assemblies on Wacker Neuson PS-series submersible pumps — including motor housings, mounting brackets, and cover plates. Although small, the fastener plays a critical role in keeping pump components clamped at the correct load; an under-torqued or damaged nut allows parts to shift, which can lead to vibration damage, seal failure, or water ingress into the motor housing. Replacing a worn or damaged nut with the correct OEM-specified part restores proper clamping force and helps maintain the overall integrity of the pump assembly.
