Key Features
- Genuine OEM Construction — Manufactured to the precise material hardness and dimensional tolerances required to maintain proper retention force in diaphragm pump assemblies.
- Drop-In Replacement — Engineered to match the original mounting position and seat geometry, allowing straightforward installation without rework or shimming.
- Confirmed Fitment — Direct replacement for STOW Diaphragm Pump models SDP-3, CA90749, and SDP-2.
- Maintains Pump Integrity — A correctly functioning retaining washer keeps internal components properly secured under operating pressure, preventing unwanted movement that can lead to accelerated wear or seal failure.
- Authorized OEM Sourcing — Supplied as a genuine Multiquip part, backed by the manufacturer's part number SP3360 for accurate identification and reordering.
A retaining washer is a fastening component used to secure and locate parts within an assembly, preventing axial movement under vibration and operational load. In a diaphragm pump, where cyclic pressure and mechanical flex are constant, a worn or missing retaining washer can allow internal components to shift, leading to misalignment, accelerated wear on adjacent parts, or loss of pumping efficiency. Replacing a damaged washer promptly with the correct OEM part helps preserve the integrity of the surrounding assembly and keeps the pump operating within its designed parameters.
