This specialized oil is designed to meet the requirements of hydraulic pump manufacturers for most industrial and marine applications, as well as mobile machinery.
Applications
Sinopec L-HM HPC™ Anti-Wear Hydraulic Oil is used in:
- Industrial and Manufacturing Systems: Suitable for various industrial hydraulic systems.
- Mobile Equipment and Off-Road Vehicles: Ideal for cranes, excavators, and forklifts where there is no extreme ambient temperature variation.
- Marine Systems: Meets requirements for marine hydraulic systems needing ISO HM hydraulic oils.
- Vane and Gear Pumps: Recommended for high-load operations as advised by pump manufacturers.
- Heavy-Duty Hydraulic Systems: Suitable for axial and radial piston pumps in severe service conditions as recommended by pump manufacturers.
Features & Benefits
- Superior Wear and Corrosion Protection: Extends the life of metal components.
- Excellent Oxidation Stability and Cleanliness: Reduces varnish and sludge formation, protecting and extending the life of hydraulic systems and pumps.
- High Demulsibility: Effective water separation, along with good anti-foam properties and rapid air release, ensures system durability and reduces corrosion risk in harsh and moist environments.
- Hydrolytic Stability and Good Filterability: Ensures optimal product performance and prevents filter blockages. The high cleanliness standard (NAS 7 or better) minimizes hard particle contamination, extending filter life and reducing maintenance downtime.
- Seal Compatibility: Fully compatible with common hydraulic seal materials, extending seal life and preventing fluid leakage.
