This premium accumulator diaphragm cup repair kit is custom engineered for RAMMER S25-LOW compact hydraulic rock breakers, widely matched with mini excavators and skid steer loaders for demolition, rock breaking and construction jobs. It includes complete accumulator diaphragm cup, matching O-rings, gaskets and auxiliary sealing rings for full breaker accumulator overhaul.
Manufactured with imported high-performance HNBR and reinforced PU polyurethane composite material, the kit delivers outstanding hydraulic oil resistance, wide temperature adaptability and superior anti-fatigue performance under high-frequency impact. It perfectly replaces original RAMMER diaphragm spare parts, solves typical faults including nitrogen leakage, insufficient impact force, hydraulic pressure instability and accumulator failure, and greatly extends breaker service life under long-term heavy impact operation.

Fully dimensional matched with original RAMMER S25-LOW breaker accumulator assembly, consistent with OEM part numbers RAMMER-S25-LOW and 41713. No cutting, grinding or modification required for direct plug-and-play installation.
Core diaphragm cup adopts imported HNBR + reinforced PU composite material with special vulcanization molding. It resists hydraulic oil corrosion, aging and repeated high-frequency stretching deformation, stable performance under -30°C to 120°C complex construction environment.
All components pass strict 18.5MPa high-pressure air tightness fatigue testing. Effectively isolates nitrogen chamber and hydraulic oil circuit, eliminates internal gas-oil mixing leakage, maintains stable accumulator energy storage efficiency and consistent breaker striking power.
Covers all sealing and diaphragm accessories required for full accumulator maintenance. Integrated complete spare parts reduce separate part purchasing steps, shorten on-site repair downtime and lower equipment overall operation maintenance cost.
Every diaphragm cup kit undergoes air tightness cyclic fatigue test, high temperature aging test and compression deformation test before delivery, fully meets OEM production standards and guarantees long-term stable performance in harsh construction scenarios.
Specially designed for RAMMER S25-LOW hydraulic breakers equipped on various light & medium construction equipment:
