This heavy-duty accumulator diaphragm cup is precision engineered for RAMMER S23-HIGH hydraulic rock breakers, widely matched to medium excavator demolition and mining machinery. It serves as the core energy-isolating component of the breaker nitrogen accumulator, separating high-pressure nitrogen and hydraulic oil perfectly.
Manufactured with imported modified HNBR + reinforced PPDI polyurethane composite material, this diaphragm cup boasts outstanding high-frequency fatigue resistance, oil resistance, tear resistance and thermal stability. It effectively solves common failures including nitrogen leakage, insufficient impact force, breaker power drop and premature diaphragm cracking, greatly extending the continuous service life of the breaker under high-intensity impact working conditions.

1. 100% Exact OEM Replacement. Fully dimensionally compatible with original RAMMER S23-HIGH breaker accumulators, matches OEM part numbers RAM-S23H and 3072619442. Direct plug-and-play installation without cutting or modification.
2. Premium Composite Reinforced Material. Core diaphragm adopts high-performance HNBR + PPDI polyurethane integrated molding with fiber reinforcement layer. Anti-aging, anti-oil corrosion and anti-tear, maintains stable elasticity under -25°C to 140°C long-term alternating temperature impact.
3. Zero Nitrogen Leakage & High-Fatigue Impact Resistance. Each product undergoes 35MPa high-pressure nitrogen sealing test and millions of high-frequency stretching fatigue tests. Eliminates internal gas-oil mixing leakage, stabilizes breaker impact energy and ensures consistent breaking power output.
4. Integrated One-Piece Molding, Easy Single-Part Replacement. Independent integral diaphragm cup design, no split assembly parts. Simplifies accumulator maintenance steps, shortens on-site repair downtime and reduces overall equipment operation maintenance cost.
5. Strict Factory Full Inspection. Every diaphragm cup passes air tightness, high pressure, high-temperature aging and cyclic impact fatigue tests before delivery, fully meets OEM original equipment production standards for stable long-term heavy-duty construction performance.
6. Wide Application Scope. Suitable for RAMMER S23-HIGH hydraulic breakers installed on multiple medium heavy-duty construction equipment:
