Product Overview
This heavy‑duty accumulator diaphragm is specially engineered for Epiroc 1840 and 1840+ hydraulic rock drills. It serves as the core rubber component of the drill’s accumulator system, resisting high‑frequency impact pressure and preventing nitrogen‑oil mixing inside the accumulator.
Manufactured from imported high‑performance FKM fluororubber compound, this diaphragm delivers outstanding fatigue resistance, oil resistance and temperature stability. It is a direct replacement for original spare parts, effectively solving common failures such as diaphragm rupture, accumulator pressure decay and unstable impact performance, extending rock drill service life under continuous heavy‑duty mining and tunneling conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with Epiroc 1840 and 1840+ rock drills. Matches OEM part numbers 3115247200 and 3115182201. Perfect dimensional accuracy enables direct installation without any modification.
2. Premium Imported FKM Rubber Material.The diaphragm adopts enhanced fluororubber formula, featuring excellent anti‑fatigue, tear‑resistant, oil‑proof and aging‑resistant properties. Maintains stable mechanical performance within‑25°C to 110°C working range.
3. High‑Frequency Impact Durability.Strictly tested under cyclic impact pressure up to 28MPa. Resists repeated rapid pressure fluctuation. Prevents nitrogen leakage and oil‑gas mixing, stabilizes drill impact power during long‑time continuous drilling.
4. Reduce Unexpected Downtime.Replaces worn or cracked original diaphragms. Avoids typical faults including weak impact force, pressure loss and accumulator failure. Minimizes unplanned maintenance and lowers total operation cost of drilling equipment.
5. Strict Factory Quality Control.Every finished diaphragm passes fatigue cycle testing, air tightness inspection and dimensional verification before delivery. Meets OEM performance standards for harsh underground and open‑pit mining environments.
6. Application Scope.Suitable for Epiroc 1840 /1840+ rock drills mounted on various heavy‑duty drilling rigs:
• Underground mining drill jumbos
• Open‑pit surface drilling rigs
• Tunnel excavation drilling equipment
• Metallurgical mine drilling machinery
• Rock bolting drilling rigs
• Heavy‑duty mobile drilling equipment
