Product Overview
This premium accumulator diaphragm is engineered for Epiroc 1838HD, 1838HD+ and 1838MUX hydraulic rock drills. It serves as the core wearing part for the nitrogen accumulator, effectively isolating hydraulic oil and nitrogen gas.
Made of imported high‑performance HNBR rubber material, the diaphragm delivers outstanding oil resistance, gas‑tight performance, impact resistance and anti‑fatigue properties. It perfectly replaces original Epiroc diaphragm parts, solves common failures such as nitrogen leakage, accumulator failure and reduced impact power, and extends rock drill service life under continuous heavy‑duty underground mining operation。

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Epiroc 1838HD, 1838HD+ and 1838MUX rock drills. Matches OEM part number 3115182201. No modification required for direct installation。
2. Premium Imported HNBR Material.The core diaphragm adopts high‑quality HNBR rubber, featuring excellent oil resistance, gas‑tightness and anti‑fatigue performance. It withstands frequent high‑frequency impact cycles and runs stably within -35°C to 150°C working range。
3. Reliable Gas‑Tight & Anti‑Impact Performance.Every diaphragm is tested under 25MPa working pressure. It prevents nitrogen leakage and oil‑gas mixing, maintaining stable accumulator energy storage and consistent rock drill impact power output.
4. High Fatigue‑Resistant For Continuous Heavy‑Duty Work.Designed for high‑frequency reciprocating impact up to 3000 cycles per minute. Strong shock and vibration resistance reduces unexpected downtime in harsh mining working conditions。
5. Strict Factory Quality Control.Each finished diaphragm passes air‑tightness, pressure and fatigue tests before delivery. It meets OEM standards and ensures stable long‑term underground mining performance.
6. Application Scope.Suitable for Epiroc 1838 series rock drills installed on various heavy‑duty drilling rig equipment:
• Underground mining drill rigs
• Tunnel boring and excavation drilling equipment
• Production drilling operations
• Hydraulic rock drill nitrogen accumulator assemblies
• Heavy‑duty mobile drilling machinery
