This heavy-duty accumulator diaphragm cup kit is specially engineered for RAMMAR S26-HIGH hydraulic rock breakers, widely matched on medium & large excavator demolition and mining machinery. It contains standard energy storage diaphragm, integral piston cup, matching O-rings, gaskets and auxiliary sealing rings for full accumulator overhaul.
Adopted imported modified HNBR + high-strength PU composite material, the kit boasts outstanding high-frequency fatigue resistance, hydraulic oil resistance, high temperature and tear resistance. It perfectly replaces original RAMMAR diaphragm cups, solves common faults including nitrogen leakage, impact power attenuation, breaker overheating and frequent diaphragm rupture, and greatly extend continuous working lifespan under long-term high-frequency striking heavy-load conditions.

Fully dimensionally matched with original RAMMAR S26-HIGH breaker accumulator components, corresponds to OEM part numbers RAM-S26H-003 and 9110426001. No cutting, grinding or modification required for direct on-site installation.
Core diaphragm and piston cup adopt imported modified HNBR and reinforced PU integrated vulcanization molding. Ultra-high tear resistance and anti-fatigue performance, stable elastic recovery under thousands of high-frequency reciprocating strikes per minute, no hardening or cracking under long-term high temperature hydraulic oil immersion.
All accessories pass 130MPa ultra-high pressure fatigue impact testing. Effectively isolate nitrogen chamber and hydraulic oil circuit, eliminate internal and external air/oil leakage, maintain stable accumulator energy storage efficiency, keep consistent breaker striking force and avoid power drop during continuous operation.
Covers all diaphragm and matching sealing spare parts required for full accumulator maintenance. Complete supporting accessories reduce on-site maintenance preparation time, lower equipment downtime and overall operation cost.
Each set undergoes air tightness, high-frequency impact fatigue, high temperature aging and oil immersion aging tests before delivery. Fully meets OEM original production standards, guarantees stable long-term performance in harsh construction sites.
Suitable for RAMMAR S26-HIGH hydraulic rock breakers equipped on multiple heavy-duty construction equipment:
Welcome to HOVOO, a Chinese seal factory. Production of PU, Rubber and PTFE seals. The seals include O-ring, piston seal, rod seal, Gray ring and gas seal.
