Product Overview
This heavy‑duty accumulator diaphragm is engineered for Epiroc 2160, 2550, 2560 hydraulic rock drills. It acts as a critical sealing component separating nitrogen gas and hydraulic oil inside the accumulator assembly. Manufactured from imported high‑performance rubber compound, this diaphragm delivers outstanding oil resistance, anti‑aging property and dynamic fatigue resistance. It perfectly replaces original Epiroc diaphragm parts, resolves typical failures such as nitrogen leakage, pressure drop and reduced impact power, and extends rock drill service life under continuous heavy‑duty mining and tunneling operations.

Key Selling Points
1. 100% Exact OEM Replacement.
Fully dimension‑matched for original Epiroc 2160 / 2550 / 2560 hydraulic rock drills. Matches OEM part number 3115247200. No modification required for direct field installation.
2. Premium Imported Rubber Material.
Core diaphragm body adopts high‑performance imported special rubber material. Excellent oil‑proof, anti‑fatigue and aging‑resistant performance, maintaining stable elasticity within working temperature range from -25°C to 110°C.
3. Anti‑Leakage & High Pressure Fatigue Resistance.
Every diaphragm passes strict high‑pressure cyclic fatigue testing under 32MPa working condition. Effectively prevents nitrogen escape and hydraulic oil cross‑contamination, sustaining stable accumulator pressure and consistent drill impact output.
4. Precise Dimensional Tolerance For Field Maintenance.
Strictly controlled forming dimension fits accumulator housing perfectly. Suitable for on‑site overhaul and replacement, shortens equipment downtime and reduces overall mining operation costs.
5. Strict Factory Quality Control.
Each finished diaphragm undergoes air‑tightness, pressure cycle and aging inspection before shipment. Meets OEM performance standard to ensure reliable long‑term performance under harsh underground working conditions.
6. Application Scope.
Specially designed for Epiroc 2160,2550,2560 rock drills mounted on various heavy‑duty drilling rigs:
• Underground mining drill jumbos
• Tunnel excavation drilling rigs
• Long‑hole drilling equipment
• Bolt and drifting drilling machinery
• Hard rock drilling working conditions
• High‑intensity continuous rock‑drilling operations
