Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the exact load and deflection specifications required to maintain consistent clamping force in submersible pump assemblies.
- Direct Drop-In Installation — Sized and profiled to seat correctly in the existing fastener stack without adjustment or shimming.
- Confirmed Fitment — Compatible with ST3020B1, ST3020BCUL, and ST3050D Multiquip submersible pump models.
- Prevents Fastener Loosening — The spring action resists vibration-induced loosening, which is critical in continuously running pump applications where fastener movement can lead to leaks or component misalignment.
- Fluid System Integrity — Maintaining correct torque retention with a properly functioning spring washer helps preserve sealed joints inside the pump housing, reducing the risk of water ingress into protected internal areas.
A spring washer is a hardened, curved or split washer placed beneath a fastener to maintain clamping load under conditions of vibration and thermal cycling. In submersible pump applications, where the unit operates continuously in water and generates sustained mechanical vibration, spring washers play a critical role in keeping fasteners secure and mating surfaces properly sealed. When a spring washer wears flat or fractures, the fastener it supports can back out gradually, leading to loose covers, compromised seals, or misaligned components that affect pump output and longevity.
