This heavy-duty accumulator piston cup diaphragma is professionally developed for Etc. K20 hydraulic rock breakers, widely matched with medium and small excavator hydraulic hammers for mining, demolition and road construction. It acts as the core isolation component between high-pressure nitrogen gas chamber and hydraulic oil circuit, solving common failures such as nitrogen leakage, impact power attenuation and unstable hammering frequency.
Adopted imported modified high-elastic FKM fluororubber with fiber reinforcement molding, the diaphragm features outstanding oil resistance, high-frequency fatigue resistance, wide temperature adaptability and anti-aging performance. It fully replaces original OEM diaphragm parts, stabilizes breaker output impact force and greatly extends the overhaul cycle of hydraulic breakers under long-term heavy-load impact operation.

Precision mold opening strictly follows original Etc. K20 dimensional standards, perfectly matching OEM part numbers ETC-K20 and 3086112001. No cutting, grinding or modification required, direct one-piece installation for fast on-site replacement.
Corpus principalis diafragmatis utitur FKM caoutchouc fluorato importato cum strato interno renfortis fibroso, efficaciter resistens corrosioni olei hydraulici, distentioni cyclicae altius frequentiae et fissurationi senectutis. Elasticitatem stabilem servat intra latum intervallum temperaturarum a -35°C usque ad 110°C, nullam rigiditatem aut deformationem sub impetu continuo fortissimo.
Transiit experimentum impactionis fatigabilis ultra-altae pressionis 130 MPa, perfecte isolans nitrogenium et oleum hydraulicum. Evitat efficaciter effugium nitrogenii, infiltrationem olei in accumulatorium et decrementum virium mallei, servans frequentiam percussivam constantem et praestantiam constanter frangendam durante operatione continua longa.
Processus vulcanizationis specialiter optimatus adaptatur centenis impactibus reciprocis altius frequentiae per minutum, resistens lacerationi, tumefactioni et perforationi. Minuit valde frequentiam substitutionis diafragmatis et minuit pretium manutenctionis apparatus.
Omnis diaphragma perfecta examinatur ad aeris hermeticitatem, ad fatigationem per impulsum alti pressionis, et ad aetationem sub temperaturis altis et bassis antequam mittatur; ita omnino satisfacit normis fabricatorum originalium (OEM), quae certificant servitium diuturnum et fidedignum in durissimis condicionibus operis constructionis.
Idoneum est pro frangibribus hydraulicis Etc. K20, quae montantur in variis machinis constructionis et extractionis: • Excavatoribus parvis et mediis (Sany SY75, XCMG XE80, Liugong 906D, Zoomlion ZE75E) • Excavatoribus retro-scoop et rotatoribus • Machinis municipalibus pro demolitione et renovatione viarum • Machinis pro conterendo lapidibus in excavariorum locis • Machinis hydraulicis pro frangendo subterraneo • Systematibus malleorum hydraulicorum mobilium robustorum
