This heavy-duty accumulator diaphragm cup is custom engineered for RAMMAR S25-HIGH hydraulic rock breakers, widely matched on medium excavator demolition and mining machinery. It acts as the core pressure isolation component of the breaker nitrogen accumulator, integrating high-elastic rubber cup and integrated diaphragm one-piece structure.
Adopted imported high-performance HNBR fluororubber composite material, the product boasts outstanding oil resistance, high pressure impact resistance, tear resistance and aging resistance. It thoroughly solves common failures including nitrogen leakage, impact force attenuation, breaker weak striking and high oil temperature caused by damaged original diaphragm cups, effectively extending the full service life of the hydraulic breaker under long-term heavy crushing, rock breaking and demolition working conditions.

Fully dimensionally matched original RAMMAR S25-HIGH breaker accumulator structure, consistent with OEM part numbers RAM-S25H-001 and 32501S25H. No cutting, grinding or modification required for direct one-step installation, perfectly replacing factory original diaphragm cups.
Core diaphragm and cup body adopt reinforced fiber HNBR fluororubber composite formula. Anti-hydraulic oil corrosion, anti-high temperature aging, ultra-high rebound elasticity, maintains stable mechanical performance under long-term alternating pressure shocks from -30°C to 125°C.
All finished products pass 18.5MPa fatigue impact cycle testing. Effectively isolate nitrogen chamber and hydraulic oil chamber, eliminate internal gas-oil mixing leakage, maintain stable accumulator energy storage pressure, guarantee consistent breaker impact power and avoid striking weakness.
Equipped with matched positioning gaskets and auxiliary O-rings required for accumulator overhaul. Complete supporting accessories simplify on-site maintenance procedures, shorten equipment downtime and reduce overall operation and maintenance costs of construction machinery.
Each diaphragm cup undergoes air tightness, high-pressure fatigue and accelerated aging testing before delivery, fully meeting OEM production standards, providing stable and reliable long-term performance for heavy-load construction sites.
Suitable for RAMMAR S25-HIGH hydraulic breakers equipped on various medium-duty construction machinery: • Medium excavators (12–18 ton class: SWE150, Lovol150, Liugong915, SDLG135) • Wheel loaders fitted with hydraulic breakers • Municipal demolition & road renovation equipment • Quarry rock crushing and mining auxiliary machinery • Foundation pit excavation, concrete breaking, old building dismantling equipment • Mobile heavy-duty hydraulic impact machinery
