Key Features
- Genuine OEM Material Grade — Sourced directly from Multiquip, this washer meets the exact thickness, hardness, and material composition required for proper load distribution in submersible pump assemblies.
- Drop-In Replacement — Matches original mounting dimensions exactly, seating and torquing correctly without modification to mating hardware or fastener threads.
- Confirmed Fitment — Compatible with Multiquip ST3020B1 and ST3020BCUL submersible pump models.
- Protects Mating Surfaces — A correctly spec'd washer distributes clamping load evenly, preventing fastener pull-through, surface gouging, and premature loosening under pump vibration and hydraulic pressure.
- Supports Submersible Environment Integrity — In a submersible application, every fastened joint matters; using the correct washer helps maintain the clamping force needed to keep seals and housings properly compressed.
A washer serves as a load-distributing interface between a fastener and the surface it bears against. In submersible pump assemblies, where components must remain securely joined under continuous vibration, water pressure, and thermal cycling, using the correct washer is critical. An undersized, oversized, or worn washer can allow fasteners to loosen, damage mounting surfaces, or compromise the integrity of sealed joints — leading to leaks or mechanical failure at depth. Replacing a worn or missing washer with the correct OEM part restores proper clamping force and helps the assembly perform as designed.
