Product Overview
This heavy‑duty accumulator diaphragm is engineered for Epiroc 1850CR hydraulic rock drill. It serves as the core nitrogen‑separating component for the drill’s accumulator system. Manufactured from premium imported HNBR and FKM fluororubber material, it delivers outstanding pressure resistance, shock resistance, oil resistance and fatigue resistance. This replacement diaphragm effectively solves common failures including accumulator pressure drop, nitrogen leakage, insufficient impact power and abnormal drilling performance, extending rock drill service life under continuous heavy‑duty underground and surface drilling operations.

Key Selling Points
1. 100% Exact OEM Replacement.Fully compatible with original Epiroc 1850CR hydraulic rock drill. Matches OEM part numbers 3115182201 and 3115182200. Direct installation without any modification.
2. Premium Imported Rubber Material.Main diaphragm body adopts high‑performance HNBR & FKM fluororubber. Excellent anti‑fatigue, oil‑proof, aging‑resistant performance, stable operation within‑35°C to 130°C wide temperature range.
3. Anti‑Leakage & High Shock Durability.Every piece undergoes strict 32MPa high‑pressure and repeated impact fatigue testing. Prevents nitrogen leakage and pressure loss, maintains stable accumulator pre‑charge pressure and consistent rock drill impact output.
4. Critical Single‑Piece Maintenance Component.This diaphragm is the key wearing spare part for accumulator overhaul. Single complete replacement part shortens on‑site maintenance time and reduces overall equipment operating costs.
5. Strict Factory Quality Control.All diaphragms pass air‑tightness, pressure‑cycling and aging tests before delivery. Meets OEM dimensional standard for reliable long‑term mining site performance.
6. Application Scope.Suitable for Epiroc 1850CR rock drill equipped on various heavy‑duty drilling rigs:
• Underground mining drilling jumbos
• Tunnel face drilling rigs
• Bolter drilling equipment
• Surface rock drilling rigs
• Hard rock excavation machinery
• Hydraulic drifter working in high‑dust mining environment
• Heavy‑duty mobile drilling machinery
