The Wacker Neuson Spring Washer is a genuine OEM component designed for the PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF series submersible pumps. As a direct OEM part, the is manufactured to the exact material and dimensional standards of the original, ensuring correct load distribution and consistent clamping force within the pump assembly. This Spring Washer fits across a broad range of PS-series configurations spanning 3-inch and 4-inch discharge sizes, multiple voltage ratings, and both high-head and high-output variants. Keeping this small but critical fastening component in good condition is essential to maintaining proper assembly integrity throughout the pump's service life.
Key Features
- OEM Spring Tension Consistency — Manufactured to original specifications, this washer delivers the correct spring rate and load-bearing capacity needed to maintain secure, vibration-resistant fastening inside a submersible pump environment.
- Drop-In Replacement — Matches the original mounting position and profile exactly, seating correctly without rework or shimming during reassembly.
- Broad PS-Series Compatibility — Fits PS3-5503, PS4-5503, PS4-7503HH, and PS4-7503HF submersible pumps across 50Hz and 60Hz configurations and a wide range of voltage ratings including 220V, 400V, 440V, and 575V variants.
- Submersible Environment Durability — Built to withstand the continuous moisture exposure and operational vibration inherent to submersible pump service, maintaining clamping performance over extended run cycles.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the full backing of the manufacturer's parts program for verified fitment confidence.
A spring washer serves as a locking and load-distributing fastener within bolted assemblies, using its curved or wave profile to maintain tension under vibration and thermal cycling. In a submersible pump, where the unit operates continuously in wet conditions and is subject to motor vibration, spring washers prevent fasteners from loosening over time and help keep internal components properly seated and aligned. When a spring washer flattens, corrodes, or loses its tension, fasteners can work loose, leading to misalignment, increased wear on surrounding components, or potential ingress of water into areas of the pump that depend on a secure seal.
