The Wacker Neuson Injection Pump is a genuine OEM component designed for the DPU6055 and DPU6555 series reversible vibratory plate compactors. As a direct OEM replacement, part is manufactured to the same specification as the original, ensuring correct fuel metering and delivery for the diesel engines powering these heavy-duty reversible plates. This pump covers an extensive range of DPU6055 and DPU6555 variants — including He, Hec, Heh, Hesh, Heap, Hecs, and US-market configurations — making it the right call for operators and service technicians working across multiple units in a fleet.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to the exact flow and pressure tolerances of the original pump, ensuring correct fuel delivery at all throttle positions for consistent diesel engine output.
- Direct Bolt-On Replacement — Matches the original mounting configuration and fuel line connections on DPU6055 and DPU6555 engines, allowing a straightforward swap without adapters or modifications to fuel system lines.
- Broad DPU6055 & DPU6555 Fitment Coverage — Confirmed fit across He, Hec, Heh, Hesh, Heap, Hecs, Hechzf, and US-market variants in both the DPU6055 and DPU6555 families, including standard, canopy, and water-cooled configurations.
- Restored Engine Power and Compaction Force — A correctly functioning injection pump maintains the fuel pressure needed for full engine torque, which directly translates to consistent centrifugal force output at the plate — critical for meeting compaction density specs on soil and aggregate bases.
- Fuel System Integrity — Using a genuine OEM injection pump eliminates the risk of pressure inconsistencies or seal incompatibilities that can lead to fuel leaks or hard-start conditions in a diesel compactor operating under sustained load.
The injection pump is a core component of the diesel fuel system, responsible for drawing fuel from the tank and delivering it to the injector at precisely controlled pressure and timing. On diesel-powered reversible plate compactors like the DPU6055 and DPU6555, accurate fuel delivery is what keeps the engine running at the RPM needed to generate full vibration amplitude and compaction force. When the injection pump wears or fails, symptoms typically include hard starting, rough idling, loss of power under load, or the engine failing to run altogether — any of which will bring compaction work to a halt and risk under-compacted layers that fail inspection.
