This heavy-duty accumulator diaphragm & seal cup repair kit is specially engineered for RAMMER S52 G200 hydraulic rock breakers, widely fitted on medium & large excavators for demolition, mining and rock crushing operations. The full set contains core accumulator diaphragm, seal cups, O-rings, gaskets and anti-extrusion backup rings for complete breaker accumulator overhaul.
Manufactured with imported high-performance PPDI polyurethane + modified HNBR composite rubber, the kit delivers outstanding high-pressure fatigue resistance, hydraulic oil resistance and wide temperature adaptability. It perfectly matches original RAMMER spare parts, solves common failures including nitrogen leakage, diaphragm rupture, unstable impact force and pressure attenuation, and greatly extends breaker service life under continuous high-frequency heavy impact working conditions.

Fully interchangeable with original RAMMER S52 G200 breaker accumulator parts, consistent with OEM part numbers RAM-S52G200, 3315289000 and 3315290590. Zero modification required for direct plug-and-play installation.
Core diaphragm and seal cups adopt high-toughness PPDI polyurethane + modified HNBR formula, with ultra-high anti-fatigue performance. It resists hydraulic oil corrosion, high-frequency repeated stretching and aging, and maintains stable elasticity from -35°C low-temperature construction to 120°C high-temperature continuous operation.
All spare parts pass strict 130MPa high-pressure fatigue cycle testing. Effectively isolates nitrogen chamber and hydraulic oil chamber, eliminates internal gas-oil mixing and external accumulator leakage, stabilizes breaker striking energy and ensures consistent breaking power output.
Covers all sealing and isolation components required for full accumulator maintenance of RAMMER S52 G200 breaker. Integrated matching parts shorten on-site repair time and reduce overall equipment maintenance cost.
Every diaphragm kit undergoes air tightness, high-pressure impact and accelerated aging tests before delivery, fully complies with OEM manufacturing standards to guarantee stable long-term performance in harsh construction scenarios.
Compatible with RAMMER S52 G200 hydraulic breakers mounted on multiple heavy-duty construction machines:
