This heavy-duty accumulator diaphragm & piston cup assembly is precision engineered for RAMMAR S23-LOW hydraulic rock breakers, matched OEM part numbers BA2323, L30, VB35, widely fitted on excavator-mounted hydraulic hammers for demolition, quarrying and construction works. It acts as the core isolation component separating high-pressure nitrogen chamber and hydraulic oil circuit, effectively solving common faults including nitrogen leakage, weak impact force, hydraulic pressure loss and breaker overheating.
Constructed with imported reinforced PPDI polyurethane + modified high-strength FKM composite rubber, the product delivers outstanding fatigue resistance, oil resistance, high pressure and temperature stability. It fully replaces original RAMMAR OEM diaphragm & piston cup, stabilizes hammer output impact energy and drastically extend breaker service life under continuous heavy-duty high-frequency striking.

Fully dimensionally consistent with original RAMMAR S23-LOW breaker spare parts, matching OEM codes BA2323, L30, VB35. No cutting, grinding or modification required for quick on-site installation, perfectly fits original accumulator housing.
Core diaphragm and piston cup adopt imported reinforced PPDI + FKM laminated structure. Ultra-high tensile and anti-fatigue performance, withstand thousands of high-frequency reciprocating deformations without cracking or permanent deformation; excellent anti-aging, hydraulic oil and corrosion resistance, stable performance under -25°C to 125°C wide temperature range.
All finished products pass strict 26MPa high-pressure nitrogen sealing test. Completely isolates nitrogen gas and hydraulic oil to eliminate internal leakage, maintains stable accumulator energy storage efficiency, solves weak striking power, slow rebound and frequent nitrogen refilling problems of old diaphragms.
Complete matching diaphragm + piston cup + auxiliary gaskets set, covers all core sealing consumables needed for accumulator overhaul. One set finishes full maintenance, cuts equipment downtime and reduces overall construction operating cost.
Each batch undergoes air tightness high-pressure test, cyclic fatigue stretching test and high-temperature aging test before delivery, fully meets OEM production standards, guarantees long-term reliable performance under continuous heavy construction load.
Specially designed for RAMMAR S23-LOW series hydraulic breakers, widely applied on multiple engineering equipment:
