The Wacker Neuson is a genuine OEM M12 x 40 Bolt designed for the PS4-11003HH and PS4-1003HF series submersible pumps, as well as PSC series three-phase submersible pumps. As a factory-original fastener, this bolt is manufactured to the exact thread pitch, grade, and dimensional tolerances required by Wacker Neuson for these pump assemblies. Covering a broad range of voltage configurations — including 220V, 440V, 575V, and 400V variants — the is the correct replacement bolt across the full PS4-11003 and PSC product lineup.
Key Features
- Factory-Correct Thread and Grade: — Manufactured to the exact M12 x 40 specification required for PS4-series submersible pump assemblies, ensuring proper torque load and secure clamping without thread mismatch.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this bolt meets the original material grade and surface treatment standards used in pump production.
- Broad PS4 and PSC Series Coverage: — Compatible with PS4-11003HH and PS4-1003HF submersible pump models across multiple voltage configurations (220V, 440V, 575V, and 400V), as well as PSC20753 and PSC31503/31603EX three-phase pump models.
- Structural Integrity Under Submersible Conditions: — A correctly specified bolt maintains housing and component integrity during pump operation; an undersized or incorrect fastener risks loosening under vibration, potentially leading to housing separation or pump failure.
- Direct Drop-In Replacement: — Matches the original bolt's length, thread pitch, and head geometry so it seats into existing bores and fastener patterns without modification.
A bolt of this specification serves as a structural fastener within the pump's housing or component assembly, securing critical sections together against the mechanical loads and vibration generated during continuous submersible operation. Using the correct M12 x 40 grade fastener ensures that clamping force is distributed properly across mating surfaces, preventing joint movement that could compromise the pump's sealed enclosure or internal alignment. When a fastener is worn, stripped, or replaced with an incorrect substitute, it can result in housing looseness, accelerated seal wear, or pump failure — making accurate part replacement essential during any pump service or rebuild.
