High-Performance Anti-Wear Hydraulic Oil from China Suppliers - Superior Lubrication & Equipment Efficiency Factory

Longhai High-Performance Hydraulic Oil is expertly formulated using severely hydroprocessed high-VI base oils and advanced imported additive technology. As a leading choice among China suppliers, this hydraulic oil provides outstanding anti-wear properties, corrosion protection, demulsibility, and effective foam control. It complies with the strictest international standards, including DIN 51524 (Part 11), Denison HF-0, and ISO HM classifications. Ideal for extreme operating conditions, this product showcases the best in hydraulic lubrication technology, making it a top preference for factories seeking reliability and performance.

    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
