Product Overview
This heavy‑duty accumulator cup and diaphragm is specially engineered for Sandvik HL1000, HL1000S and HL1010 hydraulic rock drills. It is the core elastic sealing component for drill accumulator units, resisting frequent high‑frequency impact and pressure fluctuation.
Manufactured with imported high‑strength fabric‑reinforced NBR and FKM fluororubber compound, this part delivers outstanding fatigue resistance, oil resistance and low‑temperature toughness. It serves as a direct replacement for original Sandvik spare parts, solving typical failures such as nitrogen leakage, pressure decay and insufficient impact power, and extends service life of hydraulic drifters under continuous high‑intensity mining and tunnelling operations.

Key Selling Points
1. 100% Exact OEM Replacement
Fully interchangeable with original Sandvik HL1000 / HL1000S / HL1010 hydraulic rock drills. Matches OEM part numbers 15225488 and 15235798. No modification required for direct field installation.
2. High‑Performance Reinforced Rubber Material
Core diaphragm and cup adopt fabric‑reinforced high‑strength FKM / NBR composite material. Excellent anti‑fatigue property against cyclic impact load, oil‑resistant, aging‑resistant, stable performance within‑35°C to 125°C working range.
3. Anti‑Leakage & Anti‑Fatigue Under Cyclic High Pressure
Each component undergoes strict pulsating pressure fatigue testing up to 28MPa. Effectively prevents nitrogen escape and hydraulic oil cross‑leakage, maintains stable accumulator pre‑charge pressure and consistent drill impact output power.
4. Purpose‑Built for Heavy‑Duty Rock Drill Conditions
Optimized structure adapts to high‑frequency impact of hydraulic drifter. Reduces unplanned downtime caused by diaphragm rupture, lowers overall equipment maintenance and operating costs.
5. Strict Factory Quality Control
Every cup‑diaphragm unit passes air tightness, pulsation fatigue and high‑low temperature aging tests before delivery. Meets original equipment performance standards to guarantee reliable long‑term performance for mining and tunnelling machinery.
6. Application Scope
Designed for Sandvik HL1000, HL1000S, HL1010 hydraulic rock drills fitted on various heavy‑duty drilling rigs:
• Underground mining jumbo drill rigs
• Surface open‑pit drill carriers
• Tunnelling and excavation equipment
• Quarry rock drilling machinery
• Hydraulic top‑hammer drill systems
• High‑load mobile drilling machinery
