This heavy-duty accumulator diaphragm (seal cup) is specially developed for KRUPP HM600 / HM601 / HM800 hydraulic rock breakers. It serves as the core energy storage sealing component of the breaker accumulator, isolating nitrogen and hydraulic oil perfectly.
Manufactured from imported high-performance HNBR composite rubber with built-in metal reinforcement plate, the diaphragm features outstanding fatigue resistance, high-pressure resistance, oil aging resistance and thermal stability. It effectively solves common failures including nitrogen leakage, insufficient striking force, diaphragm rupture and pressure attenuation, greatly extending the continuous operation life of medium-large KRUPP hydraulic breakers under quarry, demolition and heavy-load mining conditions.

Fully consistent with original KRUPP HM600/HM601/HM800 diaphragm size and installation groove structure, matching OEM part numbers KRUPP-HM600-ACC and HM800-DIA-001. No cutting, grinding or modification required for fast on-site replacement.
Core rubber body adopts imported high tensile HNBR material, equipped with integrated metal middle plate to enhance structural rigidity. Superior resistance to hydraulic oil oxidation, repeated bending fatigue and high-temperature aging, stable performance under long-term alternating pressure impact.
All finished diaphragms pass strict 125MPa burst pressure and cyclic fatigue tests. Effectively block nitrogen escape and hydraulic oil cross-leakage, maintain stable accumulator energy storage capacity, guarantee continuous strong striking power of the breaker without power drop.
Adopts integral vulcanization molding process without splicing gaps. Perfectly fits accumulator shell sealing surface, avoids partial deformation and air leakage caused by long-time high-frequency impact, reduces frequent nitrogen refilling maintenance frequency.
Every diaphragm undergoes air tightness detection, high-pressure aging cycling and bending fatigue testing before delivery, fully meets KRUPP original equipment quality standards, stable and reliable for long-term heavy industrial use.
Designed for KRUPP HM600/HM601/HM800 hydraulic breakers installed on multiple heavy construction machinery:
