The Wacker Neuson 5100013808 is a genuine OEM Diaphragm designed for the DPU6555, DPU4545, and DPU5545 series reversible vibratory plate compactors. As a factory-sourced component, it is manufactured to the exact material and dimensional specifications required for proper fuel system function in these heavy-duty diesel-powered compactors. This part fits multiple configurations across the DPU6555Heh US, DPU6555Hech US, DPU4545Heh US, DPU4545Hech US, DPU5545Heh US, and DPU5545Hech US models. Always verify your model number before ordering to confirm compatibility.
Key Features
- Genuine OEM Material Integrity — Manufactured to Wacker Neuson's original flex-material specification, ensuring the diaphragm delivers the correct pressure response and seal within the fuel system.
- Direct-Fit Replacement — Engineered to match the original mounting profile and port dimensions, allowing straightforward installation in the existing fuel pump housing.
- Broad DPU Series Compatibility — Confirmed fitment across DPU6555, DPU4545, and DPU5545 reversible plate compactor models, including both Heh and Hech US variants.
- Consistent Fuel Delivery — A correctly functioning diaphragm maintains steady fuel flow to the engine; a cracked or fatigued diaphragm causes hard starting, rough running, or complete fuel starvation.
- Fuel System Safety — A failed diaphragm can allow fuel to leak internally or externally, creating a fire hazard on the worksite. Replacing a worn diaphragm promptly is a critical safety measure.
The diaphragm is a flexible membrane located inside the fuel pump that creates the reciprocating pressure needed to draw fuel from the tank and deliver it to the carburetor or injection system at a controlled rate. It flexes thousands of times per operating hour, and over time the material hardens, cracks, or tears — disrupting fuel flow and causing the engine to run poorly or not at all. Replacing a worn diaphragm restores proper fuel delivery and keeps the compactor running at full compaction output.
