The Multiquip 0401450300 Washer QP-D302 is a genuine OEM component designed for the D302 series quick-prime pump. As a direct OEM part sourced through Multiquip's authorized supply chain, it is manufactured to the exact specifications required for the D302, ensuring a correct, confident fit every time. DHS Equipment stocks this part to keep your pump back in service without the guesswork of compatibility concerns.
Key Features
- Genuine OEM Material Specification — Produced to Multiquip's exact material and dimensional tolerances for the washer seating surface on the D302, maintaining proper load distribution and sealing integrity.
- Drop-In Replacement — Engineered to match the original mounting geometry of the D302, so installation follows the same procedure as the factory-installed component.
- Confirmed D302 Fitment — Specifically validated for the Multiquip D302 quick-prime pump series; always verify your model code before ordering.
- Protects Mating Surfaces — A properly sized and rated washer distributes clamping force evenly, preventing fastener pull-through, surface damage, and premature joint failure under operating vibration and pressure.
- Supports Pump Integrity — Worn or incorrect washers can allow fasteners to loosen during operation, leading to leaks or component misalignment; replacing with the correct OEM part restores proper joint clamping.
A washer serves as a load-spreading interface between a fastener and the surface it bears against. In pump assemblies like the D302, washers play a critical role in maintaining consistent clamping force across joints that are exposed to continuous vibration, fluid pressure, and thermal cycling. When a washer deforms, corrodes, or is substituted with an incorrect size, fasteners can loosen, gaskets can fail to seal, and mating surfaces can suffer damage that compounds into larger repairs. Using the correct OEM washer — built to the right dimensions and material grade — ensures the joint performs as intended throughout the service life of the pump.
