The Bomag 05715430 Diaphragm is a genuine OEM replacement built for Bomag BW 75 AD and BW 75 ADL walk-behind light rollers and BW 1050 T, BW 650 T, BW 850 T, BW 850 TR, and BW 85 T trench compactors. Sourced directly from Bomag, this diaphragm matches the original component specification exactly, ensuring a correct drop-in fit with no guesswork on compatibility. Confirmed fitment across both the walk-behind roller and trench compactor lines makes part number 05715430 a dependable service replacement when this component reaches the end of its service life.
Key Features
- Genuine OEM Material Integrity — manufactured to Bomag's original flex-fatigue and pressure-retention specifications, so the diaphragm seats and seals the way the machine was designed to operate
- Direct Drop-In Replacement — matches the original mounting profile and thickness, allowing straightforward installation without modification to surrounding components
- Broad Verified Fitment — confirmed for the BW 75 AD and BW 75 ADL walk-behind light rollers and the BW 850 T, BW 850 TR, BW 1050 T, BW 650 T, and BW 85 T trench compactors
- Consistent Pressure Control — a sound diaphragm maintains proper fluid or air separation within the system; a cracked or fatigued diaphragm leads to pressure loss, erratic response, and accelerated wear on connected components
- Fuel System Safety Relevance — when used in a fuel or carburetor circuit, a failed diaphragm can allow fuel contamination or uncontrolled flow, making timely replacement important for safe machine operation
A diaphragm is a flexible membrane that separates two chambers within a pump, valve, or carburetor assembly, using its flexing motion to regulate pressure, control fluid flow, or actuate a mechanical response. It acts as a dynamic seal — allowing controlled movement on one side while isolating the other side from contamination or unwanted pressure transfer. When a diaphragm develops cracks, stiffness, or pinholes from age and heat cycling, the system it serves loses the ability to build or hold pressure correctly, resulting in hard starting, rough running, fuel delivery issues, or loss of hydraulic response depending on its application.
