This heavy-duty accumulator cup diaphragma is custom-engineered for RAMMAR G120, G130 and BR7013 hydraulic rock breakers, a core energy-isolation spare part widely fitted on medium & large excavator demolition machinery. It acts as a sealing barrier separating high-pressure nitrogen chamber and hydraulic oil circuit, effectively solving common failures including nitrogen leakage, weak impact force, breaker power drop and rapid oil temperature rise.
Manufactured with imported reinforced PU composite + modified high-elastic NBR, the diaphragm delivers outstanding fatigue resistance, high-pressure resistance, oil aging resistance and anti-tearing performance. It perfectly matches OEM original dimensions, restores stable striking energy and extends the full service life of hydraulic breakers under continuous heavy crushing work.

Perfecte congruens cum dimensionibus originalium fractorum Rammar G120/G130/BR7013; compatibilis cum codicibus partium OEM RM-G120-DIA, RM-G130-DIA, BR7013-MEM01. Nulla resectio aut modificatio requiritur pro installatione directa in unum gradum.
Adoptat formulam dualem compositam ex PU alto rendimento importato + NBR modificato, cum strato integrato renfortis fibrosum. Praebet excellentem resistentiam ad oleum, ad aetationem ozoni et altam elasticitatem resilientes; retinet performance physicas stabiles in ambiente operativo longo a −25°C usque ad 120°C.
Testatus est rigorose sub pressione maxima operativa 28 MPa in cyclis fatigae. Sustinet milliones deformationum reciprocationis altae frequentiae sine fissuris, deformatione permanenti vel fuga gasi. Stabilizat pressionem nitrogeni et conservat vim percussivam fractoris constanter per totum diem.
Solvet perfecte problemata frequens causata a diafragma defectu: effugium nitrogenii, potentia percussiva insufficiens, reditus lentus mallei, supercalefactio olei hydraulici, vibratio interruptoris anormalis, minuitur usura secundaria componentium pistonis et cylindri.
Unumquodque diafragma probatur ante distributionem pro airtightness sub alta pressione, fatigatione cyclica, aetatione sub alta temperatura, et tolerantiis dimensionum; plene ad normas productionis OEM satisfacit, stabilis et fidus pro operationibus onerosis in locis constructionis per longum tempus.
Concipitur exlusivum pro interruptoribus hydraulicis Rammar G120, G130, BR7013 adhibitis in variis machinis constructionis gravibus: • Excavatores mediocres et magni (12–20 ton) • Machinae frangendae rupis in mineis et demolitoriae in lapidiculis • Machinae frangendae concreti viarum et destruendae veterum aedificiorum • Unitates hydraulicae ingeniariae municipalis • Interruptores onerosi pro lapidiculis, metallurgia, et excavatione tunnellarum • Systemata accumulatoria martellorum hydraulicorum pro operatione continua
