This heavy-duty accumulator diaphragm (nitrogen cup membrane) is specially developed for Indeco HP600 hydraulic rock breakers. It is the core sealing component of the breaker nitrogen accumulator, isolating high-pressure nitrogen and hydraulic oil thoroughly. Adopted imported high-performance modified PU + reinforced NBR composite material, it features outstanding fatigue resistance, high pressure resistance, oil resistance and high temperature resistance. It perfectly replaces original Indeco OEM diaphragm, solves common faults such as nitrogen leakage, impact force attenuation and abnormal hammer jumping, and greatly extends continuous working life under long-cycle high-frequency impact mining and demolition operations.

Fully matched with original Indeco HP600 breaker accumulator structure, consistent with OEM part numbers MES553 and HP600-DIA01. No cutting, grinding or modification required for direct replacement installation.
Main body adopts imported high-toughness modified PU with fiber reinforced edge, matched with high-performance NBR substrate. Excellent anti-fatigue, anti-aging and hydraulic oil corrosion resistance, stable elastic performance under -35°C ~ 135°C alternating temperature environment.
Finished product undergoes strict 130MPa high-pressure nitrogen sealing test. Effectively prevent nitrogen escape and internal oil cross-leakage, maintain stable accumulator energy storage efficiency, guarantee consistent breaker impact force without power drop during long-time continuous operation.
Integrated thickened edge + multi-layer fiber interlayer design, effectively resist repeated high-frequency stretching and impact deformation. Avoid edge cracking, bulge and rupture which are common problems of ordinary diaphragms, reduce frequent replacement frequency.
Every diaphragm passes air tightness, high-pressure fatigue cycle and high-temperature aging tests before delivery. Fully meets Indeco original equipment manufacturing standards, stable and reliable for long-term heavy industrial use.
Perfect matching Indeco HP600 hydraulic breakers equipped on various heavy-duty construction & mining equipment: • Large mining excavators • Mine rock crushing & secondary blasting equipment • Highway & tunnel demolition machinery • Reinforced concrete demolition hammers • Stone quarry breaking equipment • Large mobile hydraulic rock breakers • Municipal old building dismantling heavy machinery
