This heavy-duty accumulator diaphragm (leather cup seal) is specially customized for EDDIE EDT2000 hydraulic rock breakers, the core pressure storage sealing component of the breaker nitrogen accumulator. It adopts imported high-performance FKM fluororubber composite reinforced fiber material, with outstanding nitrogen resistance, hydraulic oil resistance, impact fatigue resistance and low-temperature toughness. Perfect OEM replacement part solves common faults such as nitrogen leakage, insufficient striking force, unstable impact frequency and abnormal pressure loss, greatly extending the service life of EDT2000 breaker under long-term mining and construction heavy-load operation.

Fully fits the original accumulator cavity of EDT2000 breaker, consistent with OEM part numbers EDT2000-DIA01 and 892002. No cutting, padding or modification required, direct plug-and-play installation.
Core diaphragm adopts FKM fluororubber mixed with high tensile fiber reinforcement. Resists nitrogen permeation, hydraulic oil corrosion, high-frequency impact fatigue and aging, maintains stable elasticity under -40°C to 130°C severe temperature fluctuation.
Finished products pass 18MPa high-pressure nitrogen tightness cycle test. Effectively isolate hydraulic oil and nitrogen to prevent air leakage, maintain constant accumulator pressure, guarantee stable 400–800bpm striking frequency and full impact energy output.
Integral one-step vulcanization molding without internal air bubbles or stress concentration. Resists continuous reciprocating impact deformation, avoids early cracking and air leakage caused by long-time rock breaking construction, reduces frequent replacement frequency.
Every diaphragm undergoes air tightness fatigue test, high-low temperature aging test and pressure cycling test before delivery, fully meets OEM production standards, stable and reliable for long-term harsh engineering working conditions.
Matched with EDT2000 hydraulic breakers installed on 18–26 ton excavators, widely used in heavy-duty operation scenarios: • Open-pit mining & stone quarry crushing • Road demolition, asphalt & concrete breaking • Foundation pit excavation & rock excavation • Municipal engineering demolition • Mountain slope rock breaking • Heavy-duty mobile construction machinery hydraulic breaking operation
