This heavy-duty accumulator piston cup and diaphragm are custom engineered for Ingersolland LM500 hydraulic rock breakers, serving as the core energy storage sealing component for the breaker nitrogen accumulator. It integrates integrated bowl-shaped piston cup and high-elasticity rubber diaphragm, fully matching the original installation structure.
Adopting imported reinforced FKM fluororubber and high-strength modified NBR composite vulcanization technology, the product features outstanding oil resistance, high-frequency fatigue resistance, tear resistance and wide temperature adaptability. It thoroughly solves common faults such as accumulator internal leakage, nitrogen escape, weak impact force and frequent diaphragm rupture, effectively stabilizing breaker output power and greatly extending the service life of LM500 hammer under long-time heavy impact working conditions.

Fully dimensional matched with original Ingersolland LM500 breaker accumulator, consistent with OEM part numbers 3022781 and 8900654. No cutting, grinding or modification required, direct plug-and-play installation.
Core piston cup and diaphragm adopt imported FKM + modified NBR double composite vulcanization. Ultra-high elasticity and anti-fatigue performance, resistant to hydraulic oil corrosion, aging and cracking, stable operation within -35°C ~ 125°C extreme temperature environment.
All finished products pass 35MPa high-pressure air tightness and cyclic impact fatigue tests. Effectively isolate hydraulic oil and nitrogen cavity, eliminate internal oil seepage and nitrogen leakage, maintain constant accumulator energy storage capacity, guarantee continuous strong impact force of the breaker.
Complete matching piston cup + diaphragm + auxiliary sealing rings, covering all sealing spare parts needed for LM500 accumulator overhaul. One set completes maintenance, shorten on-site repair downtime and reduce equipment comprehensive operation cost.
Each batch of piston cup diaphragm undergoes air tightness, high-frequency stretching fatigue, high-low temperature aging and oil immersion aging tests before delivery. Reach OEM original equipment standard, deliver stable and long-lasting performance for heavy construction sites.
Specially matched for Ingersolland LM500 hydraulic breakers widely equipped on multiple heavy-duty equipment: • 18–26 ton medium & large excavators • Road demolition & municipal reconstruction equipment • Quarry stone crushing machinery • Mine tunnel excavation rock breaking hammers • Concrete structure dismantling equipment • Mobile hydraulic engineering crushing machinery
