This high-performance accumulator diaphragm seal cup is specially developed for Furukawa HB200 hydraulic rock breakers. It is the core sealing component of the breaker nitrogen accumulator, responsible for isolating hydraulic oil and nitrogen gas. Adopting imported high-toughness HNBR hydrogenated nitrile rubber composite material, the product features outstanding oil resistance, shock resistance, wear resistance and low-temperature flexibility. It perfectly matches the original Furukawa size standard, effectively solving common faults such as nitrogen leakage, weak striking force and frequent pressure loss of the breaker, greatly extending the continuous working life of the breaker under harsh mining and demolition heavy-load conditions.

Precision CNC molding strictly follows the original Furukawa HB200 drawing size, fully compatible with the original accumulator assembly. Matches OEM part numbers HB200-DIA01 and FRK-HB200-ACC-MEM. No cutting, grinding or other modification required for quick on-site installation.
Core diaphragm body adopts high-performance imported HNBR rubber, compared with ordinary NBR rubber, it has stronger anti-aging, anti-fatigue and hydraulic oil corrosion resistance. It keeps stable elasticity under -40°C low temperature and 130°C high temperature, no hardening, cracking or permanent deformation after long-term impact vibration.
Each product undergoes 130MPa high-pressure air tightness and repeated impact fatigue testing before delivery. The thickened reinforced edge design avoids edge tearing under frequent hammer impact, completely isolates nitrogen and hydraulic oil, stabilizes accumulator internal pressure, and keeps the breaker striking force consistent without attenuation.
Integral curved seal cup integrated molding process, no splicing gaps, avoids hidden leakage risks at joints. Long service life reduces the frequency of shutdown replacement, cuts construction downtime and equipment maintenance costs for mines and engineering fleets.
All finished diaphragms pass air tightness test, high pressure endurance test, high-low temperature cycle aging test and impact fatigue test, fully meet Furukawa original factory quality standards, stable and reliable long-term heavy-duty operation performance.
Suitable for Furukawa HB200 hydraulic breakers equipped on all kinds of heavy construction machinery:
