This heavy-duty accumulator diaphragm & piston cup repair kit is specially developed for SOCOMEC hydraulic rock breakers DMS267, DMS310, DMS330, MDO250, MDO260, DMS410, widely fitted on excavators, demolition machinery and mining equipment. It includes matching accumulator diaphragm, piston cup, auxiliary O-rings and wear-resistant backing rings for full energy storage chamber overhaul.
Constructed with imported high-performance HNBR and reinforced polyurethane composite material, the kit delivers outstanding oil resistance, high-frequency fatigue resistance and wide temperature adaptability. It fully replaces original SOCOMEC diaphragm & piston cup parts, solves typical failures including nitrogen leakage, insufficient impact force, accumulator failure and hydraulic pressure attenuation, and greatly extends breaker service life under continuous heavy impact working conditions.

Precision dimensional forming fully matches original SOCOMEC DMS/MDO series breakers, corresponding to official OEM part numbers. No cutting, modification or shimming required for direct plug-and-play installation, perfectly fitting the accumulator cavity structure.
Core diaphragm and piston cup adopt high-toughness HNBR polyurethane composite material via secondary vulcanization molding. Excellent hydraulic oil aging resistance, anti-fatigue performance, stable elasticity under long-term high-frequency reciprocating deformation, no hardening or cracking under -30°C ~ 125°C working environment.
All components pass strict high-pressure nitrogen tightness cycle tests under 16.0MPa rated working pressure. Effectively isolate nitrogen chamber and hydraulic oil circuit, eliminate internal gas-liquid mixing leakage, maintain stable accumulator energy storage efficiency and consistent breaker striking force, avoid power drop and frequent nitrogen refilling.
Integrates all core consumables and auxiliary sealing accessories needed for accumulator maintenance of DMS267/DMS310/DMS330/MDO250/MDO260/DMS410 models. One set covers full overhaul, saves part matching time and reduces equipment downtime & maintenance cost.
Every diaphragm, piston cup and sealing accessory undergoes dimensional inspection, high-pressure air tightness test, high-frequency fatigue impact test and high-temperature aging test before delivery, fully compliant with OEM production standards to guarantee long-term reliable performance under harsh construction sites.
Perfect matching SOCOMEC DMS/MDO series hydraulic breakers for multiple heavy-duty construction scenarios:
