Key Features
- Genuine OEM Material Spec — Manufactured to the exact thickness, hardness, and surface finish required for correct load bearing in these diaphragm pump assemblies — no guesswork on fitment.
- Direct Drop-In Replacement — Matches the original mounting geometry of the PDT2, PDT2A, PDT2B, PDI2, and PDI2A series, seating correctly against mating fasteners and surfaces without rework.
- Broad PDT2 and PDI2 Family Coverage — Fits multiple model variants across the 50mm/2-inch diaphragm trash pump lineup, consolidating your parts inventory for faster turnaround on pump servicing.
- Protects Fastener Integrity — A correctly spec'd washer distributes clamping load evenly, preventing fastener pull-through, surface galling, and loosening under the vibration typical of trash pump operation.
- Verified Wacker Neuson Part Number — Sourced directly from Wacker Neuson, so part number 5000074395 cross-references cleanly against your service manual without substitution uncertainty.
A washer may be a small component, but it plays an important role in maintaining proper clamping force and protecting the surfaces around fastened joints inside a diaphragm pump. By distributing the load applied by a bolt or nut over a wider area, the washer prevents the fastener from digging into or deforming softer housing surfaces during assembly and under operational vibration. When a washer is missing, worn thin, or deformed, fasteners can work loose over time, leading to fluid leaks, misalignment of pump components, or accelerated wear on surrounding parts — all of which affect the pump's ability to move water reliably on site.
