The Wacker Neuson is a genuine OEM M12 X 20 Bolt designed for the PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 series submersible pumps. Sourced directly from Wacker Neuson, this bolt meets the exact material grade, thread pitch, and dimensional specifications called out in the original equipment build. It fits across the full PS-series submersible pump range, covering 2-inch, 3-inch, and 4-inch discharge models in both 50 Hz and 60 Hz configurations. When a fastener in this application loosens or fails, it can compromise housing integrity and lead to seal failure or pump disassembly under load — replacing it with the correct OEM part keeps the pump assembled and operating as intended.
Key Features
- Correct Thread and Grade for Pump Housing Loads — manufactured to the exact M12 x 20 thread specification and material grade required to maintain proper clamping force across the PS-series pump housing.
- Genuine OEM Part — supplied by Wacker Neuson as original equipment, ensuring 5000150738 matches the torque spec, coating, and dimensional tolerances of the part it replaces.
- Broad PS-Series Coverage — a single part number covers PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 submersible pump models across multiple voltage configurations.
- Drop-In Replacement — matches the original bolt's head size, shank length, and thread engagement, installing directly into existing threaded bores without rework.
- Protects Pump Integrity Under Submersed Operation — a correctly torqued fastener maintains housing compression and seal alignment, which is critical when the pump is operating fully submerged under continuous load.
Fasteners like the M12 X 20 Bolt serve a structural role in holding the pump housing, motor casing, or mounting components together under the mechanical and hydraulic stresses of submersed pumping operation. A bolt that is stretched, corroded, or incorrectly sized will not maintain the clamping load needed to keep mating surfaces sealed and aligned. In submersible pump applications, a compromised fastener can allow water ingress into the motor housing or cause progressive misalignment of internal components, leading to accelerated wear or pump failure. Replacing worn or damaged fasteners with the correct OEM specification part restores the structural integrity the manufacturer designed into the assembly.
