Product Overview
This high-performance diaphragm and cup seal is professionally engineered for Atlas Copco DP2500 heavy-duty hydraulic breaker, the core large-scale demolition equipment of Atlas DP series hydraulic crushing machines widely deployed in mine demolition, large infrastructure construction and urban old building dismantling hydraulic systems. The complete set includes accumulator energy storage diaphragm and hydraulic piston cup seal, fully supporting full overhaul and daily maintenance of DP2500 hydraulic breaker.
Adopting thickened fabric-reinforced NBR nitrile rubber and high-strength wear-resistant PU polyurethane as core sealing materials, this diaphragm & cup seal delivers outstanding nitrogen resistance, ultra-high pressure resistance, anti-fatigue impact and anti-aging performance. It serves as a reliable direct replacement for original Atlas Copco OEM sealing spare parts. The product effectively resolves common malfunctions including accumulator nitrogen leakage, cylinder internal oil leakage and system pressure attenuation, and significantly extends the service life of DP2500 breaker under long-duration heavy-load impact, severe vibration and high-dust harsh construction working conditions.

Key Selling Points
1. 100% Exact OEM Replacement
Fully compatible with original Atlas Copco DP2500 hydraulic breaker and precisely matched with standard OEM dimensions and part numbers. No cutting, grinding or extra modification is required. It enables quick direct installation for daily maintenance, field full machine overhaul and emergency on-site repair, effectively cutting down equipment downtime and labor maintenance costs.
2. Thickened Composite High-Grade Sealing Materials
Core energy storage diaphragm adopts multi-layer fabric-reinforced NBR with ultra-high tear resistance and elastic recovery, capable of millions of heavy impact cycles without cracking; hydraulic piston cup seal uses high-hardness cast PU material with strong anti-extrusion, anti-wear and anti-deformation capacity. The materials feature strong resistance to nitrogen aging, hydraulic oil corrosion and long-cycle fatigue deformation. It maintains stable and reliable sealing performance continuously within the temperature range of -40°C to 125°C, adapting to alpine open-pit mining and high-temperature underground demolition construction environments.
3. Superior Ultra-High Pressure & Heavy Impact Resistance
The diaphragm and cup seal have passed strict 30MPa high-pressure and long-cycle heavy impact simulation tests. It thoroughly eliminates accumulator nitrogen leakage and cylinder internal oil leakage, stabilizes hydraulic impact pressure, and ensures consistent powerful striking force of DP2500 breaker under heavy rock crushing, continuous high-frequency impact and strong vibration working conditions.
4. Specialized Customized Structure for DP2500
Independently developed for DP2500 large breaker accumulator and piston sealing position, the deep curved bowl-shaped structure fits the inner cavity perfectly without gap leakage. Single independent moisture-proof packaging simplifies spare parts inventory sorting, shortens the overall repair cycle and reduces daily operation and maintenance costs of large demolition equipment.
5. Rigorous Factory Multi-Process Quality Inspection
Every diaphragm and cup seal undergoes air tightness test, ultra-high-pressure durability test and cyclic impact aging test before delivery. All products comply with original factory technical standards, providing long-term stable operation guarantee for large mine and engineering hydraulic demolition equipment.
6. Extensive Application Scope
Specially designed for Atlas Copco DP2500 heavy hydraulic breaker, widely used on various large heavy-duty engineering and mining equipment:
• Open-pit mining: Ore rock mass breaking, mine waste rock demolition, quarry large stone splitting
• Urban demolition: High-rise concrete building dismantling, bridge concrete crushing, road foundation hard rock excavation
• Infrastructure engineering: Tunnel rock excavation, hydropower dam foundation trimming, mountain highway rock blasting auxiliary crushing
• Port & metallurgy: Factory waste steel structure demolition, slag solid material breaking
• Emergency rescue engineering: Landslide rock clearing, frozen soil large-scale breaking, dangerous rock stabilization operation
