Genuine DF-15D Accumulator Diaphragm for Delta F-15 Hydraulic Breaker
The DF-15D Diaphragm (Accumulator Membrane) is a high-performance elastomeric sealing component engineered specifically for the nitrogen accumulator gas cell in hydraulic breakers/hammers, including the Delta F-15 / Furukawa F15 / Kent F15 series attachments.
Thank you for choosing SPARKLING MACHINERY.
The DF-15D accumulator diaphragm is molded from premium, oil-resistant NBR/HNBR rubber. Built to endure continuous flex cycles and fluctuating operating temperatures, it retains nitrogen gas pressure to keep the hydraulic breaker operating at peak frequency while protecting carrier pumps from destructive pressure surges.
The SPARKLING MACHINERY NEW DF-15D Diaphragm Photo:
The SPARKLING DF-15D Accumulator Diaphragm is a professional replacement component designed for the Delta F-15 hydraulic breaker. It helps maintain accumulator performance by separating the hydraulic oil from the nitrogen gas, supporting stable energy storage and release during breaker operation.
--- Product Highlights
- Application: Delta F-15 hydraulic breaker
- Part type: Accumulator diaphragm
- Function: Maintains gas-oil separation inside the accumulator
- Use: Replacement and maintenance of hydraulic breaker accumulator systems
A worn or damaged diaphragm can cause gas leakage, reduced impact energy, irregular breaker performance, and increased hydraulic system stress. Replacing it with a properly matched DF-15D diaphragm helps restore consistent breaker operation and reduce unnecessary downtime.
Manufactured with carefully selected elastomer materials and controlled production processes, this diaphragm is designed to withstand repeated pressure cycles, vibration, and demanding construction environments. Its accurate fit supports easier installation and reliable sealing when used with a compatible Delta F-15 accumulator assembly.
