High-performance anti-wear hydraulic oil - excellent lubrication protection, improve equipment efficiency

Longhai High-Performance Hydraulic Oil is formulated with severely hydroprocessed high-VI base oils and premium imported additive technology. This scientifically engineered fluid delivers exceptional anti-wear, corrosion protection, demulsibility, and foam control, meeting the most stringent international standards including DIN 51524 (Part 11), Denison HF-0, and ISO HM classifications. Designed for extreme operating conditions, it represents the pinnacle of hydraulic lubrication technology.  

    Key Features & Benefits

    1. Superior Anti-Wear & Rust Protection
    - Micro-friction additive technology reduces metal-to-metal contact by 60% (FZG test results)
    - Dual-action corrosion inhibitors protect both ferrous and copper alloys in steel-copper friction pairs
    - Exceeds ASTM D665 rust test requirements with perfect score after 1000+ hours
    - Specially formulated for vane pumps operating at pressures up to 250 bar

    2. Advanced Foam Control & Air Release
    - Silicon-free antifoam package achieves 0ml foam after 5 minutes (ASTM D892)
    - Rapid air release <0.2% (ISO 9120) prevents micro-dieseling and cavitation
    - Reduces system noise by 15dB compared to conventional hydraulic oils

    3. Extended Oxidation Stability
    - Synthetic antioxidant system doubles service life (3000+ hours in ASTM D943)
    - Thermal stability up to 130°C prevents varnish formation
    - Maintains viscosity within ±5% through extended drain intervals

    4. Ashless Formula for Maximum Compatibility
    - Zero copper corrosion (1A rating per ASTM D130)
    - Safe for all seal materials (NBR, FKM, EPDM)
    - Ideal for axial piston pumps with bronze components

    Technical Specifications

    - Viscosity Grades: ISO VG 32, 46, 68

    - VI >140 for wide temperature operation (-30°C to 100°C)
