Product Overview
This heavy‑duty accumulator diaphragm cup seal is specially engineered for Sandvik HL1560T hydraulic rock drill. It serves as the core rubber pressure‑bearing component for the nitrogen accumulator, effectively isolating hydraulic oil and nitrogen gas.
Manufactured from imported high‑performance HNBR hydrogenated nitrile rubber and reinforced fabric composite material, this part delivers outstanding fatigue resistance, oil resistance, impact resistance and anti‑aging performance. It perfectly replaces original Sandvik diaphragm cup seal, solves typical failures such as accumulator gas leakage, insufficient impact power and unstable drilling performance, and extends service life of the rock drill under continuous high‑frequency heavy‑duty mining operation.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Sandvik HL1560T hydraulic rock drill. Matches OEM part numbers 55035052 and 55035048. No modification required for direct field installation.
2. Premium Reinforced Composite Material.Core diaphragm adopts high‑strength fabric‑reinforced HNBR rubber. Excellent resistance to high‑frequency cyclic impact, hydraulic oil corrosion and aging, stable operation within‑25°C to 110°C working temperature range.
3. Anti‑Leakage & High‑Frequency Fatigue Resistance.Every unit undergoes cyclic pressure fatigue test under 20MPa maximum working pressure. Prevents nitrogen leakage and oil permeation, maintains stable accumulator pressure and consistent drill impact power.
4. Complete Matching Repair Accessory.Set includes main diaphragm cup seal plus supporting O‑rings and gaskets required for accumulator overhaul. Complete spare parts reduce on‑site maintenance time and lower mining equipment operating cost.
5. Strict Factory Quality Control.Each diaphragm cup seal passes air tightness, pressure cycle and aging tests before delivery. Meets original equipment standards, ensuring reliable long‑term performance in harsh mine working conditions.
6. Application Scope.Suitable for Sandvik HL1560T rock drill equipped on various heavy‑duty drilling equipment:
• Sandvik Pantera series open‑pit top‑hammer drill rigs
• Open‑pit quarry drilling machinery
• Large‑scale surface mining drilling equipment
• Open‑pit mine production blast‑hole drilling rigs
• Heavy‑duty mobile rock‑drilling machinery
• High‑power hydraulic top‑hammer drifter systems
