Product Overview
This heavy‑duty accumulator cup‑diaphragm is specially engineered for Sandvik HL1500/X2 hydraulic rock drifters. It serves as the core gas‑oil isolation component for the drifter accumulator, resisting high‑frequency impact, pressure fluctuation and harsh mining site conditions.
Manufactured from imported high‑performance HNBR composite rubber with fabric‑reinforced structure, this diaphragm delivers outstanding fatigue resistance, oil resistance and anti‑aging performance. It is a direct replacement for original Sandvik spare parts, effectively solving common failures such as accumulator pressure loss, gas‑oil mixing and early diaphragm rupture, and extends overhaul cycles under continuous high‑intensity rock‑drilling operations。

Key Selling Points
1. 100% Exact OEM Replacement
Fully dimensionally compatible with original Sandvik HL1500/X2 rock drifter accumulator. Matches OEM part numbers 15235798, 04114808 and 15225488. No modification required for direct on‑site installation。
2. Premium Reinforced HNBR Material
Core diaphragm adopts imported fabric‑reinforced HNBR rubber. Excellent fatigue‑resistance against high‑frequency impact, oil‑proof and aging‑resistant, stable performance within ‑30°C to +110°C working temperature range, adapted to underground mine high‑dust and variable‑temperature environment。
3. Stable Gas‑Oil Isolation & Anti‑Burst Performance
Every diaphragm is tested under 28 MPa cyclic pressure impact. Prevents gas‑oil mixing and accumulator pressure decay, maintains stable impact power output of the rock drifter and avoids unplanned downtime caused by diaphragm rupture.
4. Targeted Heavy‑Mining‑Condition Design
Optimized cup‑shaped structural design for frequent pressure surges of hydraulic drifter accumulator. Greatly improves anti‑tear performance and service life compared with ordinary NBR diaphragms, reduces frequency of spare‑part replacement.
5. Strict Factory Quality Control
All cup‑diaphragms pass cyclic pressure fatigue test, burst pressure test and aging test before delivery. Meets OEM drawing standards to ensure reliable long‑term performance for underground and open‑pit mining operations.
6. Application Scope
Specially for Sandvik HL1500/X2 hydraulic rock drifter equipped on various heavy‑duty mining & tunneling equipment:
• Underground mining drill jumbos
• Open‑pit production drilling rigs
• Tunnel boring & excavation equipment
• Large‑scale rock bolting rigs
• Hard‑rock drifting machinery
• High‑power hydraulic drilling systems
• Heavy‑duty mobile mining machinery
