The Multiquip 0202020B608 Wave Washer is a genuine OEM component designed for ST3050D, ST3020B1, and ST3020BCUL submersible pump models. Sourced directly from Multiquip, this washer matches the original specification installed at the factory, ensuring correct load distribution and fit within the assembly. It is sold by DHS Equipment as an authorized Multiquip replacement part, giving you confidence that you are receiving the correct component for your machine. Verified fitment covers the ST3050D, ST3020B1, and ST3020BCUL submersible pump series.
Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the original wave profile and material grade, maintaining consistent axial load and spring back force within the pump assembly.
- Direct Drop-In Fit — Matches the original bore diameter, thickness, and wave geometry so it seats correctly without modification during reassembly.
- Confirmed Submersible Pump Fitment — Compatible with ST3050D, ST3020B1, and ST3020BCUL models, making it straightforward to order the right part the first time.
- Protects Rotating Components — Maintains correct preload on adjacent bearings or seals, preventing premature wear caused by axial play in the pump stack.
- Built for Wet Environments — As a genuine OEM part, this wave washer is specified to withstand the internal conditions of a submersible pump, including continuous exposure to moisture and mechanical vibration.
A wave washer is a thin, corrugated spring element used inside mechanical assemblies to apply a controlled axial load between components. In a submersible pump, it is typically positioned to take up slack, maintain preload on bearings or seals, and absorb vibration within the pump stack. When a wave washer loses its spring tension — through fatigue, corrosion, or improper reassembly — adjacent components can develop unwanted play, accelerating wear on seals and bearings and reducing overall pump efficiency. Replacing a worn or damaged wave washer with the correct OEM part restores the proper load balance in the assembly and helps the pump run as intended.
