This heavy-duty accumulator diaphragm (seal cup) is specially developed for Furukawa HB1200 & HB1500 large hydraulic rock breakers. It is the core gas storage sealing part of the breaker nitrogen accumulator, solving common faults such as nitrogen leakage, weak impact force and unstable hammer output caused by aging, cracking and deformation of original diaphragms.
Manufactured with imported high-performance HNBR & reinforced fluororubber composite material, the product features outstanding anti-fatigue, oil resistance, low temperature flexibility and high pressure resistance. It perfectly matches the original Furukawa installation size, effectively prolongs the continuous working life of the breaker under high-frequency impact heavy-duty mining and demolition conditions.

Fully dimensional consistent with original Furukawa HB1200/HB1500 diaphragm, corresponds to OEM part numbers 8951127 and 9082156. No trimming, no modification, direct snap-on installation, perfectly fits accumulator inner cavity without gas gap.
Core diaphragm adopts multi-layer HNBR-FKM composite structure with fiber reinforcement inside. Excellent anti-aging, anti-tear and anti-fatigue performance, resistant to hydraulic oil erosion and long-term high-frequency reciprocating stretching, not easy to harden or crack under extreme temperature alternating environment.
Pass 130MPa ultra-high pressure air tightness and cyclic impact fatigue testing. Effectively lock nitrogen pressure inside accumulator, maintain stable energy storage buffer effect, eliminate breaker weak hitting, intermittent impact and rapid nitrogen loss problems, keep consistent breaking efficiency for long-time operation.
Independent finished diaphragm seal cup, directly replace the old damaged diaphragm during breaker routine maintenance, match all supporting seal accessories of HB1200/HB1500 repair kits, simplify maintenance procedures and reduce equipment downtime cost.
Each diaphragm undergoes raw material tensile test, high-low temperature aging test, repeated impact fatigue test and air tightness leak detection before delivery. Fully meets Furukawa original factory quality standards, stable and reliable for long-term harsh industrial operation.
Suitable for Furukawa HB1200 & HB1500 hydraulic breakers equipped on various heavy-duty excavators and engineering equipment: • Large mining excavators • Stone quarry rock crushing operations • Urban building demolition projects • Road & tunnel excavation construction • Mine open-pit stripping work • Heavy-duty mobile hydraulic crushing equipment • Large-scale foundation engineering machinery
