Product Overview
This high-performance accumulator diaphragm and piston cup seal is professionally engineered for Atlas Copco CP3050 heavy-duty hydraulic rock drill, a mainstream large impact hydraulic breaker widely used in mining, tunnel excavation and large-scale demolition projects. The complete set includes energy storage diaphragm for nitrogen accumulator and reciprocating piston cup seal, fully meeting full machine overhaul and daily maintenance demands of CP3050 hydraulic drill.
Adopting fabric-reinforced NBR nitrile rubber and high-wear PU polyurethane as core raw materials, this sealing assembly boasts outstanding nitrogen penetration resistance, high-frequency impact resistance, abrasion resistance and anti-fatigue aging performance, serving as a perfect direct replacement for original Atlas Copco spare parts. It thoroughly solves common faults such as accumulator nitrogen leakage, cylinder internal oil leakage and hydraulic pressure attenuation, greatly extending the service life of CP3050 rock drill under long-time heavy-load impact, strong vibration and dusty harsh operation environments.

Key Selling Points
1. 100% OEM Dimension Matching, Direct Installation Without Modification
Fully compatible with original Atlas Copco CP3050 rock drill, consistent with original factory outline size and OEM part number. No cutting, grinding or secondary modification required. Supports quick assembly for daily maintenance, field full overhaul and emergency rush repair, effectively cutting equipment downtime and labor maintenance cost.
2. Premium Composite Sealing Material, Stable Sealing in Full Temperature Range
The energy storage diaphragm adopts fabric-clamped NBR substrate with excellent tear resistance and elastic recovery, resisting cracking after tens of thousands of continuous impact cycles. The piston cup seal uses high-hardness PU material with strong anti-extrusion and anti-wear capacity. The material features superior resistance to nitrogen aging, hydraulic oil corrosion and fatigue deformation, maintaining stable elastic sealing performance from -40°C alpine mining to 120°C high-temperature underground tunneling conditions.
3. High Pressure & Anti-Vibration Performance, Eliminate Oil & Gas Leakage
All sealing components pass strict 28MPa high-pressure endurance and long-cycle impact simulation tests. Curved bowl-shaped structure fits the inner cavity perfectly, completely eliminating nitrogen leakage of accumulator and internal oil seepage of cylinder. Stabilize hydraulic impact pressure, guarantee constant striking force of CP3050 drill under heavy rock breaking, continuous impact and high-vibration working conditions.
4. Customized Dedicated Structure, Easy Spare Parts Management
Independently molded for CP3050 accumulator and piston sealing positions, matched with equipment internal cavity contour. Single independent packaging simplifies spare parts classification and inventory management, shortens overall machine repair cycle and lowers daily operation and maintenance expenses.
5. Strict Factory Inspection, Quality Reaches Original Standard
Each set of diaphragm and cup seal undergoes air tightness leak test, high-pressure durability test and cyclic impact aging test before delivery. All performance indicators comply with Atlas Copco original technical standards, providing long-term stable operation guarantee for mining and engineering hydraulic equipment.
6. Wide Application Coverage
Specially matched for Atlas Copco CP3050 large hydraulic rock drill, applicable to multiple heavy-duty construction and mining scenarios:
• Mining Industry: Underground roadway tunneling, open-pit ore excavation, stone quarry mass rock breaking
• Tunnel Engineering: Mountain highway tunnel, mine main roadway, municipal pipe gallery rock drilling
• Municipal Demolition: Large concrete foundation crushing, old bridge dismantling, urban hard rock excavation
• Water Conservancy Project: Hydropower tunnel rock excavation, dam foundation trimming, river channel hard rock clearing
• Emergency Rescue: Landslide rock splitting, frozen soil breaking, slope stabilization drilling
