The Wacker Neuson Stud Bolt is a genuine OEM component designed for the PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF series submersible pumps. As a direct OEM replacement, this stud bolt is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct thread engagement and clamping load across all covered configurations. This part supports a wide range of voltage variants — including 220V, 440V, 575V, and 400V/50Hz models — making it a versatile service item for dewatering fleets running mixed pump inventories.
Key Features
- Genuine OEM Thread Specification: — Manufactured to exact thread pitch and shank dimensions, delivering the correct torque loading required for secure pump assembly on PS4-series submersible units.
- Drop-In Hardware Replacement: — Installs directly into existing pump housings without modification to mating fastener points or flange interfaces.
- Broad PS4 Series Coverage: — Fits PS4-7503HH, PS4-7503HF, PS4-11003HH, and PS4-11003HF pumps across 220V, 440V, 575V/60Hz, and 400V/50Hz configurations, covering both High Head and High Output variants.
- Structural Integrity Under Submersed Load: — A correctly torqued stud bolt maintains housing seal compression and prevents fastener-related leaks in demanding continuous-duty dewatering applications.
- Pressure-Critical Fastener: — On submersible pump assemblies, fastener integrity directly affects housing seal performance; using the correct OEM stud bolt is essential to maintaining watertight assembly at operating depth and pressure.
A stud bolt is a threaded fastener used in pump housing assemblies to clamp flanges, end covers, or motor casings together with consistent, measurable clamping force. On submersible pumps like the PS4 series, these fasteners hold critical sealing surfaces under continuous hydraulic and mechanical load — meaning a stretched, corroded, or incorrectly sized stud bolt can compromise housing integrity and allow water ingress into the motor cavity. Replacing worn or damaged stud bolts with genuine OEM hardware restores the correct clamp load and protects downstream components from water damage.
