Product Overview
This high-performance accumulator diaphragm and piston cup seal is specially developed for Atlas Copco COP1150 heavy-duty hydraulic rock drill, a mainstream underground tunneling rock drill of COP series widely applied in metal mine roadway excavation, tunnel engineering and underground rock drilling hydraulic systems. The complete set includes nitrogen accumulator energy storage diaphragm and hydraulic reciprocating piston cup seal, fully supporting full overhaul and daily maintenance of COP1150 rock drill.
Adopting fabric-reinforced NBR nitrile rubber and high wear-resistant PU polyurethane as core raw materials, this diaphragm & cup seal features excellent nitrogen permeation resistance, high-frequency impact resistance, abrasion resistance and anti-fatigue aging performance, serving as a fully interchangeable direct replacement for original Atlas Copco sealing spare parts. It effectively solves common faults such as accumulator nitrogen leakage, cylinder internal oil leakage and system impact pressure attenuation, greatly extending the service life of COP1150 rock drill under long-time heavy impact, severe vibration and high-dust underground harsh working conditions.

Key Selling Points
1. 100% OEM Standard Size, Direct Installation Without Modification
Fully matched with original Atlas Copco COP1150 rock drill in overall dimension, installation profile and OEM part number. No cutting, grinding or secondary modification required. It can be quickly assembled for daily maintenance, underground overhaul and emergency field repair, effectively cutting equipment downtime and manual maintenance costs.
2. Premium Composite Special Material, Stable Sealing Under Full Working Conditions
The energy storage diaphragm adopts fabric-reinforced nitrile substrate with outstanding tear resistance and elastic recovery, resisting cracking after tens of thousands of high-frequency impact cycles; the piston cup seal is made of high-hardness polyurethane with strong anti-extrusion and wear resistance. 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 construction environments.
3. High Pressure & Impact Resistant, Eliminate Oil & Nitrogen Leakage
Both diaphragm and cup seal pass strict 25MPa high-pressure durability and long-cycle impact simulation tests. The curved bowl-shaped structure fits the inner cavity perfectly, completely eliminating nitrogen leakage of accumulator and internal oil seepage of cylinder. It stabilizes hydraulic impact pressure and guarantees constant striking force of COP1150 rock drill under heavy rock breaking, continuous impact and strong vibration working conditions.
4. Special Customized Structure for COP1150, Convenient Maintenance Management
Independently molded for COP1150 accumulator and piston sealing positions with precise curved bowl contour matching the cavity. Single independent packaging simplifies spare parts inventory classification, shortens overall repair cycle and reduces daily operation & maintenance costs of underground drilling equipment.
5. Strict Multi-Round Factory Inspection, Quality Reaches Original Factory Standard
Every 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 meet Atlas Copco original technical standards, providing long-term stable operation guarantee for underground mining and tunnel hydraulic drilling equipment.
6. Wide Application Scenarios for Underground Heavy-Duty Drilling
Customized supporting parts for Atlas Copco COP1150 hydraulic rock drill, widely used in various underground heavy engineering and mining projects:
• Metal Mine Industry: Underground roadway tunneling, ore body drilling, stope bolt support drilling
• Tunnel Engineering: Mountain traffic tunnel excavation, hydraulic tunnel rock breaking, urban underground pipe gallery drilling
• Non-Metal Quarry: Underground stone mining, rock anchor hole construction
