--- Product Highlights
- Compatible application: Delta F-45 hydraulic breaker
- Component type: Accumulator diaphragm
- Designed for reliable sealing and pressure separation
- Suitable for excavator breaker maintenance and repair
- Professional replacement solution for worn or damaged diaphragms
A properly functioning accumulator diaphragm is essential for separating hydraulic oil from the accumulator gas chamber. When the diaphragm becomes aged, cracked, deformed, or damaged, the breaker may experience reduced impact power, abnormal pressure fluctuations, slower operation, or increased vibration. Replacing the diaphragm in time can help restore stable performance and reduce the risk of further hydraulic system damage.
