Key Features
- Genuine OEM Material Integrity — Manufactured to Multiquip OEM specifications, ensuring the correct hardness, thickness, and load-bearing capacity expected of a retaining washer in a diaphragm pump application.
- Direct Drop-In Replacement — the part installs in the same position as the original washer with no rework or modification to mating components required.
- Confirmed SDP-3 Fitment — Verified for use with STOW SDP-3 series diaphragm pumps; reference model code SDP-3 when ordering to confirm applicability.
- Maintains Pump Assembly Integrity — A correctly seated retaining washer keeps internal components properly secured under operating pressure; a worn or missing washer can lead to component migration, seal failure, or fluid leakage.
- Built for Demanding Pump Environments — Designed to withstand the cyclical pressure and fluid exposure typical of diaphragm pump service, supporting consistent pump output and extended service intervals.
A retaining washer serves as a mechanical fastening element that holds a mating component — such as a shaft, valve, or seat — securely in its designed position within the pump assembly. In a diaphragm pump, this type of washer is subjected to repeated pressure cycles and must maintain its seating without deforming or migrating. When a retaining washer wears, cracks, or is lost during service, the components it secures can shift out of alignment, leading to internal leakage, loss of prime, or accelerated wear on surrounding parts.
