Hoc accumulatōrium robustum diaphragma cup (leather cup) is specially developed for KRUPP HM380 hydraulic rock breakers. It is the core energy-isolating sealing component of the breaker nitrogen accumulator, fully separating high-pressure nitrogen and hydraulic oil to stabilize impact force.
Adopted imported reinforced NBR and high-toughness FKM fluororubber with fiber-reinforced vulcanization process, it features outstanding oil resistance, anti-fatigue, high-frequency impact resistance and wide temperature adaptability. Perfect OEM replacement for original KRUPP HM380 diaphragm, solves common failures such as nitrogen leakage, insufficient striking power, frequent accumulator inflation and premature diaphragm rupture, greatly extending breaker service life under continuous mining & demolition heavy load.

Fully matched with original KRUPP HM380 breaker accumulator structure, corresponds to OEM part numbers 332/A2425 and 332/C7817. Precise size without trimming, direct installation to replace old diaphragm cup.
Main diaphragm body uses fiber-reinforced modified NBR, key stress area adopts FKM fluororubber composite layer. Ultra-high tensile and anti-fatigue performance, resistant to hydraulic oil corrosion, no hardening or cracking under long-term high-frequency reciprocating deformation. Stable operation range from -35°C to 125°C.
Omnia perfecta sunt diafragmata passes 26 MPa high-pressure nitrogen tightness test. Effectively isolates oil and nitrogen, eliminates air mixing, maintains constant striking energy, avoids power attenuation and overheating failure of the breaker main body. Thickened edge anti-tear structure prevents edge cracking under long shock load.
Unus finitus diafragmatis vasus paratus est pro maintenance accumulatoris, nullae gaskettae auxiliares necessariae sunt pro substitutione ordinaria. Simplificat proceduras reparationis in loco, breviat tempus inoperationis apparatus et minuit totalem pretium maintenance machinarum constructionis.
Omnis copia subicitur testibus vulcanizationis aetatis, impactus fatigae altius frequentiae et inspectionis hermeticitatis aeris antequam admittatur. Plene satisfacit normis technicis fabricae originalis, stabilis et fidabilis pro condicionibus operativis longis et asperis in mineris et constructione.
Idoneus pro frangendis roccis hydraulicis KRUPP HM380, quae montantur in variis machinis constructionis gravioribus:
