The Wacker Neuson Stud Bolt is a genuine OEM fastener designed for the PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 series submersible pumps. Sourced directly from Wacker Neuson, this stud bolt meets the exact specifications used in original production, ensuring correct thread engagement, torque retention, and sealing integrity within the pump assembly. It is compatible across a wide range of voltage configurations — covering 50 Hz and 60 Hz models rated from 220 V through 575 V — making it a versatile service part for both domestic and international pump variants. Confirm your model and machine number against the fitment list before ordering to ensure a correct match.
Key Features
- Genuine OEM Threaded Fastener — Manufactured to Wacker Neuson's original thread pitch and material grade, delivering the clamping force and corrosion resistance required in submersible pump environments.
- Drop-In Installation — Matches the original stud bolt position and thread specification exactly, allowing straightforward installation without recutting or chasing threads.
- Broad PS-Series Compatibility — Fits PS2-3703, PS3-3703, PS4-3703, PS3-5503, and PS4-5503 submersible pumps across 50 Hz and 60 Hz variants from 220 V to 575 V.
- Maintains Pump Housing Integrity — A correctly torqued stud bolt holds pump casing sections under load; a worn or stripped stud can allow housing separation, seal failure, and water ingress into electrical components.
- Electrical Safety Relevance — Proper fastener tension is critical in submersible electric pumps to maintain housing seals that protect motor windings from water contact.
A stud bolt is a headless threaded fastener that extends from a fixed point in the pump housing, allowing a nut to be torqued against a mating component or cover to create a secure, repeatable clamping joint. In submersible pump assemblies, stud bolts are commonly used to secure motor housings, volute casings, or end covers where a conventional bolt head cannot be accommodated. When a stud bolt becomes corroded, stripped, or damaged, the clamping load across the joint is compromised, which can allow the pump casing to shift under operating pressure or permit water to bypass seals and reach the motor — leading to motor failure. Replacing a damaged stud bolt with the correct OEM part restores the joint to its original rated clamping specification.
