Hoc accumulatōrium robustum diaphragma (ex corio sigillum Calicis is specially developed for GB300E hydraulic rock breakers, a core energy storage sealing component widely installed on medium excavator hydraulic hammers for mining, road construction and demolition works. It functions as an isolation barrier between the nitrogen chamber and the hydraulic oil circuit, and is compatible with full overhaul set sigillorum of GB300E breaker.
Fabricatus cum FKM fluorocaucho renforti importato et materiali composito NBR modificato alti elastici, hic diafragma praebet excellentem resistentiam ad oleum, resistentiam ad altas temperaturas, resistentiam ad fatigam et resistentiam ad lacerationem. Hoc solvit defectus communes ut vim percussivam debilem, fugam nitrogenii, infiltrationem olei hydraulici in accumulatorem et damnum frequentem annulorum sigillantium, stabilizans effectum percussivum frangentis et magnopere extendens vitam operativam frangentis sub operatione continua altae frequentiae et oneris gravissimi.

Precise molding strictly according to GB300E original drawing; fully interchangeable with OEM part numbers GB-300E-DIA and 300E081201. Standard size—no trimming or modification required; direct installation into original accumulator housing.
Core diaphragm employs high-performance FKM composite rubber with fiber-reinforced layer, featuring ultra-high fatigue resistance. Withstands millions of high-frequency stretching cycles without permanent deformation; resistant to hydraulic oil corrosion, aging, and high-temperature impact.
Passed 28 MPa long-duration high-pressure fatigue test. Fully isolates nitrogen gas from hydraulic oil; eliminates gas-oil mixing failure; maintains constant nitrogen energy storage pressure; restores full striking power of breaker.
Comes with matched O-rings and anti-extrusion backup rings required for accumulator maintenance. All supporting sealing parts are one set supplied, shorten on-site overhaul time and reduce equipment downtime cost.
Every GB300E diaphragm undergoes air tightness test, high-frequency fatigue test and high-temperature aging test before delivery, fully meets OEM production standards, guarantees stable long-term performance under harsh construction conditions.
Suitable for GB300E hydraulic breakers mounted on multiple medium-sized engineering equipment:
