Product Overview
This heavy‑duty accumulator diaphragm kit is specially engineered for Epiroc SC25 hydraulic rock drill. It includes main diaphragm, O‑rings, gaskets and auxiliary sealing components for accumulator overhaul service.
Manufactured from imported high‑performance HNBR and FKM fluororubber material, this kit delivers outstanding fatigue resistance, oil resistance and temperature stability under high‑frequency impact working conditions. It serves as a perfect replacement for original Epiroc diaphragm parts, resolves common failures such as accumulator pressure drop, pressure fluctuation and oil‑gas mixing, and extends rock drill service life under continuous heavy‑duty drilling operations.

Key Selling Points
1. 100% Exact OEM Replacement. Fully compatible with original Epiroc SC25 hydraulic rock drill accumulator. Matches referenced OEM part numbers 3122‑7891‑00 and 3122‑7892‑00. No modification required for direct field installation.
2. Premium Imported Sealing Material.Core diaphragm component adopts high‑strength HNBR & FKM rubber. Anti‑fatigue formula resists repeated high‑frequency impact cycles, featuring oil‑proof, aging‑resistant and deformation‑resistant performance, operating reliably within -25°C to 110°C temperature range.
3. Stable Accumulator Pressure & Anti‑Fatigue Performance.All components pass strict impulse and pressure cycling tests up to 24 MPa working pressure. Prevents gas‑oil mixing and internal pressure leakage, maintains steady impact power output for rock drill.
4. Complete All‑in‑One Overhaul Kit.Contains all diaphragm and sealing accessories required for accumulator maintenance. Complete one‑set parts shorten on‑site repair time and reduce overall equipment operating costs.
5. Strict Factory Quality Control.Every diaphragm kit undergoes air tightness, impulse fatigue and high‑pressure testing before shipment. It meets OEM equivalent standards and guarantees stable long‑term performance in mining jobsites.
6. Application Scope.Suitable for Epiroc SC25 rock drill mounted on multiple heavy‑duty drilling equipment:
• Surface drill rigs for quarry operation
• Open‑pit mining drilling machines
• Construction engineering drilling rigs
• Top‑hammer drill carriers
• Medium‑hole rock drilling equipment
• Heavy‑duty mobile drilling machinery
