Hoc accumulatōrium robustum diaphragma (sigillum Calicis is custom engineered for AMPA600 hydraulic rock breakers, widely matched on medium excavators and construction demolition machinery. It is the core energy storage sealing part for breaker accumulators, isolating nitrogen chamber and hydraulic oil circuit completely.
Adopted imported high-strength modified HNBR and reinforced PU composite material, this diaphragm delivers outstanding oil resistance, high temperature resistance, fatigue resistance and anti-tear performance. It directly replaces original AMPA600 OEM diaphragm, thoroughly solves common failures including nitrogen leakage, impact power attenuation, abnormal blow frequency and short service life, stabilizing breaker output under long-time high-frequency impact working conditions.

Fully dimensional consistent with original AMPA600 breaker diaphragm, matches OEM part numbers AMPA-600-DIA and 3120669801. No cutting, grinding or modification required for direct plug-and-play installation.
Core diaphragm body adopts imported modified HNBR with PU reinforcing layer. Excellent hydraulic oil corrosion resistance, low-temperature flexibility and high-temperature anti-aging, maintains stable elasticity within -30°C ~ 135°C working range.
Each piece undergoes 130 MPa high-pressure nitrogen tightness test and millions of reciprocating impact fatigue tests. Effectively prevents nitrogen escape, maintains stable accumulator energy storage capacity, ensures consistent impact force without power drop during continuous operation.
Optimized integral cup shape design with thickened transition arc, effectively disperses instantaneous pressure impact, avoids edge cracking and local tearing caused by frequent compression rebound, greatly extending service life compared to ordinary rubber diafragmata .
All finished diaphragms pass air tightness, high pressure, fatigue aging and oil immersion tests before delivery, fully meet AMPA original equipment manufacturing standards, reliable for long-term heavy demolition working scenarios.
Suitable for AMPA600 hydraulic rock breakers equipped on multiple medium-duty construction equipment:
