Product Overview
This high‑performance accumulator diaphragm cup seal is specially engineered for Montabert HC50 hydraulic rock drifters. It serves as the core nitrogen‑separating component for the drill accumulator, resisting high‑frequency impact and pressure fluctuation.
Manufactured from imported high‑strength HNBR composite rubber material, this diaphragm features outstanding fatigue resistance, nitrogen‑gas resistance and impact‑resilient performance. It perfectly replaces original Montabert OEM diaphragm parts, solving typical failures such as nitrogen leakage, insufficient impact power and accumulator pressure loss, extending service life under continuous heavy‑duty drilling conditions.

Key Selling Points
1. 100% Exact OEM Replacement.Fully dimension‑compatible with original Montabert HC50 hydraulic rock drifter. Matches OEM part number 86633963. No modification required for direct field installation.
2. Premium Imported Rubber Material.Adopts high‑performance HNBR composite rubber raw material. Excellent gas‑tightness against nitrogen, anti‑fatigue and anti‑aging properties, stable operation within‑35°C ~ 110°C working range.
3. Anti‑Fatigue & Stable Pressure Performance.Every diaphragm withstands cyclic impact pressure testing up to 14 MPa. Effectively prevents nitrogen leakage, maintains stable accumulator pre‑charge pressure and consistent drill impact output power.
4. Critical Single‑Unit Wear Part.Ready‑to‑use replacement diaphragm for accumulator overhaul. Reduces on‑site maintenance downtime and lowers overall equipment operating costs.
5. Strict Factory Quality Control.Each diaphragm undergoes air‑tightness, cyclic pressure and fatigue aging tests before shipment. Meets OEM dimensional and performance standards for reliable long‑term mining‑site operation.
6. Application Scope.Suitable for Montabert HC50 hydraulic rock drifter equipped on multiple heavy‑duty engineering machinery:
• Underground mining drill jumbos
• Tunnel excavation drilling rigs
• Quarry rock‑drilling equipment
• Slope bolting & anchoring rigs
• Hydraulic drilling trolley systems
• Hard‑rock underground construction machinery
• High‑frequency impact rock‑drilling working conditions
