Product Overview
This high-performance diaphragm and cup seal is professionally engineered for Atlas Copco CP1650 handheld hydraulic rock breaker, a core heavy-duty model of CP series hydraulic demolition equipment widely used in mining quarry, municipal demolition and road construction hydraulic systems. The complete set includes accumulator energy storage diaphragm and hydraulic piston cup seal, fully supporting full overhaul and routine maintenance of CP1650 hydraulic breaker.
Adopting fabric-reinforced NBR nitrile rubber and wear-resistant PU polyurethane as core raw materials, this diaphragm and cup seal features outstanding nitrogen resistance, high-frequency impact resistance, wear resistance and anti-aging performance, which can directly replace original Atlas Copco sealing spare parts. The product effectively solves common failures such as accumulator nitrogen leakage, cylinder internal oil leakage and system pressure attenuation, greatly extending the service life of CP1650 breaker under long-term high-frequency striking, intense vibration and dusty severe working conditions.

Key Selling Points
1. 100% Exact OEM Replacement
Fully matched with original Atlas Copco CP1650 hydraulic breaker, consistent with OEM standard dimensions and part numbers. No cutting, grinding or secondary modification needed. It supports rapid direct installation for daily maintenance, field overhaul and emergency on-site repair, greatly reducing equipment downtime and labor maintenance costs.
2. Premium Composite Sealing Materials
The energy storage diaphragm adopts fabric-reinforced NBR base material with excellent 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 PU material with strong anti-extrusion and wear resistance. The raw materials resist 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 & Anti-impact Performance
All sealing components pass strict 28MPa high-pressure durability and long-cycle impact simulation tests. The curved bowl structure fits the inner cavity tightly, completely eliminating nitrogen leakage of accumulator and internal oil leakage of cylinder, stabilizing hydraulic striking pressure, and ensuring constant striking force of CP1650 breaker under heavy rock breaking, continuous impact and strong vibration working conditions.
4. Special Customized Structure for CP1650
Independently developed for the accumulator and piston sealing positions of CP1650 breaker, the bowl-shaped curved surface perfectly fits the equipment cavity. Single independent packaging simplifies spare parts inventory classification, shortens overall repair cycle and cuts daily equipment operation and maintenance expenses.
5. Strict Factory Quality Inspection
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 OEM technical standards, providing long-term stable operation guarantee for mining and engineering hydraulic equipment.
6. Wide Range of Application Scenarios
Specially matched for Atlas Copco CP1650 hydraulic breaker, suitable for all kinds of heavy mining and construction projects:
• Mining Industry: Underground roadway excavation, ore rock drilling, stone quarry exploitation
• Municipal Demolition: Concrete pavement breaking, old building demolition, pipeline foundation excavation
• Road & Bridge Engineering: Mountain rock excavation, tunnel construction, subgrade hard rock crushing
• Water Conservancy Projects: Hydropower tunnel rock breaking, dam foundation trimming
• Emergency Rescue Works: Rock splitting, frozen soil breaking, slope reinforcement drilling
