Product Overview
This high-performance accumulator diaphragm and piston cup seal is custom developed for Atlas Copco DP3600 heavy hydraulic breaker (DP3600 hydraulic hammer), a large tonnage heavy breaking equipment widely used in mine quarrying, large foundation excavation, road demolition and tunnel engineering. The complete set includes nitrogen accumulator energy storage diaphragm and hydraulic impact piston cup seal, fully supporting full overhaul and routine maintenance of DP3600 breaker.
Adopting thickened fabric-reinforced NBR nitrile rubber and high-strength wear-resistant PU polyurethane as core raw materials, this diaphragm & cup seal features outstanding nitrogen penetration resistance, ultra-high pressure resistance, anti-fatigue impact and anti-aging performance, serving as a direct interchange replacement for original Atlas Copco OEM sealing parts. It thoroughly solves common failures such as accumulator nitrogen leakage, cylinder internal oil leakage, continuous pressure drop and unstable striking power, greatly extending the service life of DP3600 under long-time heavy-load high-frequency impact, strong vibration and dusty harsh construction environments.

Key Selling Points
1. 100% OEM Size Matching, Direct Installation Without Modification
Fully consistent with original DP3600 size, outline and installation size, perfectly matched with factory OEM part standards. No cutting, grinding or secondary modification required. Suitable for daily maintenance, field full machine overhaul and emergency site repair, effectively shortening equipment downtime and reducing labor maintenance costs.
2. Thickened Composite Special Sealing Material, Stable Sealing for All Working Conditions
The energy storage diaphragm adopts multi-layer fabric-reinforced NBR base material, featuring ultra-high tear resistance and elastic recovery, resisting tens of millions of continuous impact cycles without cracking or air leakage; the piston cup seal uses high-density cast PU material with strong anti-extrusion, anti-scuff and wear-resistant performance. The material resists nitrogen aging, hydraulic oil corrosion and fatigue deformation, maintaining stable sealing elasticity continuously from -40°C alpine mining to 120°C high-temperature underground operation.
3. Ultra High Pressure & Heavy Impact Resistance, Eliminate Oil & Gas Leakage
All sealing components pass strict 18MPa long-cycle high-pressure impact simulation tests. The deep bowl-shaped curved structure fits the inner cavity of DP3600 accumulator tightly, completely eradicating nitrogen leakage from energy storage tank and internal oil leakage of impact cylinder. Stabilize hydraulic output pressure, guarantee constant striking force of DP3600 breaker under heavy rock breaking, continuous high-frequency impact and severe vibration working conditions.
4. Special Customized Structure for DP3600, Convenient Spare Parts Management
Independently molded according to the special cavity size of DP3600 accumulator and impact piston sealing position, the arc bowl-shaped structure fits perfectly without gap. Single independent vacuum packaging, convenient for spare parts classification and inventory management, shorten overall repair cycle and reduce long-term equipment operation and maintenance costs.
5. Strict Multi-Round Factory Inspection, Quality Reaches Original Factory Standard
Each set of diaphragm and cup seal undergoes air tightness leakage test, high-pressure durability test and cyclic impact aging test before delivery. All performance indicators meet Atlas Copco original technical standards, providing long-term stable operation guarantee for large mining and engineering heavy hydraulic breaking equipment.
6. Wide Application Scope for Heavy-Duty Construction Scenarios
Specially matched for Atlas Copco DP3600 heavy hydraulic breaker, widely applied in all kinds of large tonnage engineering and mining equipment:
• Open-pit mining: Large stone quarry blasting-free rock crushing, mine ore bulk breaking
• Municipal demolition: Large concrete foundation dismantling, highway bridge old structure breaking
• Road & tunnel engineering: Mountain hard rock excavation, highway tunnel rock drilling, roadbed boulder crushing
• Water conservancy & hydropower: Dam foundation trimming, hydropower station rock excavation
• Infrastructure construction: Subway foundation pit hard rock breaking, port wharf rock treatment
• Emergency rescue: Landslide rock splitting, frozen soil breaking, dangerous rock removal
