This heavy-duty accumulator diaphragm cup is specially developed for RAMMAR BA2424 L20 VB25 hydraulic rock breakers, the core energy storage sealing part inside breaker nitrogen accumulators. It isolates high-pressure nitrogen chamber and hydraulic oil circuit, solves common failures including nitrogen leakage, weak impact force, unstable striking and frequent pressure loss.
Adopted imported reinforced HNBR composite rubber with high fatigue resistance, it withstands high-frequency reciprocating impact for long-term heavy construction operation, perfectly replaces original RAMMAR OEM diaphragm, stabilizes breaker output power and greatly extend whole machine service life.

Fully matched original RAMMAR BA2424 L20 VB25 breaker size and mounting structure, consistent with OEM part numbers RAMMAR-BA2424-L20 and VB25-DIA001. No trimming or modification needed, direct one-step installation.
Core diaphragm adopts imported fiber-reinforced HNBR composite rubber, with superior oil resistance, nitrogen penetration resistance, high temperature aging resistance and anti-cracking performance. Stable elastic performance under -35°C ~ 135°C alternating cold & hot construction environment.
Each diaphragm undergoes 130MPa ultra-high pressure nitrogen tightness test before delivery. Effectively prevent nitrogen leakage, maintain constant accumulator pressure, guarantee continuous powerful striking force without power attenuation during long-time rock breaking work.
Special vulcanization molding process, resist thousands of high-frequency stretch cycles per minute without permanent deformation, crack or delamination. Service life 30% longer than ordinary NBR diaphragms, reduce frequent replacement downtime and maintenance cost.
All finished products pass air tightness, high pressure impact, thermal aging and fatigue cycle tests, fully reach OEM production standard, stable and reliable for long-term heavy mining and construction operation.
Designed exclusively for RAMMAR BA2424 L20 VB25 hydraulic breakers installed on various heavy-duty engineering equipment:
