The Wacker Neuson is a genuine OEM Spring Washer designed for the PS2-3703, PS3-3703, PS4-3703, and PSC series submersible pumps. As a factory-sourced component, it meets the original engineering specifications set for these electric submersible pump families across a wide range of voltage configurations, including 220V, 440V, 575V, and 400V/50Hz variants. This Spring Washer is a direct-fit replacement that installs exactly as the original, keeping your pump assembly properly tensioned and secured. Whether you are servicing a 2-inch, 3-inch, or 4-inch discharge model, part number is the correct OEM choice.
Key Features
- OEM Spring Tension Rating: — Manufactured to the original load and deflection specification, ensuring consistent clamp force across the pump assembly rather than a generic approximation.
- Broad Series Coverage: — Fits PS2-3703, PS3-3703, PS4-3703, and PSC-series submersible pumps across 2-inch, 3-inch, and 4-inch discharge sizes in both 50Hz and 60Hz configurations.
- Drop-In Installation: — Matches the original washer geometry and bore size, seating correctly against mating fasteners without modification or shimming.
- Maintains Fastener Integrity Under Vibration: — A functioning spring washer prevents fastener back-off during pump operation; a worn or flattened washer allows hardware to loosen, leading to misalignment or seal failure inside the pump housing.
- Genuine Wacker Neuson OEM Part: — Sourced directly through the Wacker Neuson parts network, carrying the same part number used by authorized service centers worldwide.
A spring washer is a small but critical fastening component used throughout the pump assembly to maintain tension on bolted connections. By exerting a continuous spring force against the fastener and mating surface, it resists the loosening effect of vibration and thermal cycling that occurs during pump operation. When a spring washer becomes flattened, corroded, or cracked, fasteners can back off progressively, compromising the structural integrity of the assembly and potentially allowing water ingress or misalignment of internal components.
