The Wacker Neuson Spring Washer M20 is a genuine OEM component designed for the PSC42203 submersible pump. Sourced directly from Wacker Neuson, this washer is manufactured to the exact material and dimensional standards required for proper fastener retention in submersible pump assemblies. Confirm your model number before ordering to ensure a correct, hassle-free fit.
Key Features
- Genuine OEM Spring Tension: — Manufactured to Wacker Neuson's original spring-rate and hardness specs, so the washer delivers consistent clamping load without losing tension over time.
- M20 Sizing, Drop-In Installation: — Sized precisely for M20 fasteners, so it seats correctly in the existing bolt pattern with no modifications to hardware or mating surfaces.
- Built for Submersible Environments: — Engineered to withstand continuous moisture exposure and the vibration loads common in submersible pump operation.
- Protects Fastener Integrity: — A functioning spring washer maintains consistent bolt tension and prevents loosening under vibration; a worn or flattened washer risks fastener migration and housing damage.
- Confirmed Fitment for PSC42203: — Verified as the correct replacement for PSC42203 series submersible pumps, cross-referenced by Wacker Neuson part number 5000177071.
A spring washer works by exerting a continuous outward force against a fastener and its mating surface, compensating for the micro-movement and vibration that would otherwise allow a bolt or nut to gradually back out. In submersible pump applications, where the assembly is exposed to constant water immersion and operational vibration, maintaining reliable bolt tension is critical to keeping housings sealed and drive components properly aligned. When a spring washer loses its temper or becomes compressed flat, fasteners can loosen progressively, leading to misalignment, leaks, or accelerated wear on surrounding components.
