Wacker Neuson 5000094884 Diaphragm

The Wacker Neuson Diaphragm is a genuine OEM component designed for a broad range of Wacker Neuson equipment including DPU reversible vibratory plate compactors, RD7 tandem rollers, PT2H and PT3H self-priming centrifugal trash pumps, the HSH350 hydronic surface heater, DS70 diesel rammer, and E1100 ground heater. As a direct OEM replacement, part is manufactured to the exact tolerances and material specifications required to maintain proper fluid control and pressure regulation across each of these machine families. This diaphragm fits an extensive range of DPU series models — from the DPU 2440H through the DPU 6555 variants — as well as multiple RD7H and RD7He roller configurations, making it one of the most widely applicable diaphragm parts in the Wacker Neuson line.

Key Features

• OEM Material Integrity — Manufactured from compound-grade elastomer material that maintains correct flex and sealing performance under the operating pressures of each compatible machine.
• Broad Cross-Family Fitment — A single part number covering DPU reversible vibratory plates, RD7 tandem rollers, PT2H and PT3H trash pumps, the HSH350 hydronic surface heater, DS70 diesel rammer, and E1100 ground heater series.
• Drop-In Replacement — Matches the OEM profile and port dimensions, allowing direct installation without machining, trimming, or adapter hardware.
• Maintains Fluid Circuit Performance — A correctly functioning diaphragm sustains consistent pressure separation and flow control; a failed or cracked diaphragm leads to fluid bypass, pressure loss, and potential contamination of adjacent systems.
• Fuel System Integrity — In fuel-circuit applications across the DPU and DS series, an intact diaphragm is critical to preventing raw fuel from entering the crankcase or air intake — a genuine safety consideration during operation.

A diaphragm is a flexible membrane that separates two chambers within a pump, valve, or carburetor-style fuel system, using its flex to move fluid or regulate pressure without allowing the two sides to mix. In trash pump and heater applications, it controls the flow of liquid or fuel through the system by expanding and contracting with each pressure cycle. When a diaphragm cracks, hardens, or develops a pinhole, the separation between chambers breaks down — leading to pressure loss, fluid leakage, erratic performance, or complete loss of prime in pump applications.
