Low Zinc Antiwear Hydraulic Oil Additive Pacakge
Advanced Anti-Wear Protection for Zinc-Sensitive Systems
The hydraulic fluid blended with this hydraulic oil additive possesses good antioxidant, anti-rusting and excellent anti-wear properties. It can prevent hydraulic pump and other components from wearing and tearing, prolonging the service life of machinery.
Product Introduction
This advanced low zinc hydraulic oil additive package is engineered for zinc-sensitive systems requiring API DMB/ISO 11158 HM performance. Combining organomolybdenum friction modifiers and low-zinc antiwear agents, it delivers robust protection against wear, oxidation, and copper corrosion while extending filter life and seal compatibility.
Key Features
- Extended Filter & Seal Life
Ashless Formulation: Sulfated ash ≤0.1% minimizes varnish and sludge, doubling filter service intervals (up to 5,000 hours).
Seal Compatibility: Fully compatible with PTFE (Turcon®), PU (Zurcon®), NBR, and FKM seals—prevents hardening/swelling even at 120°C.
- Thermal & Oxidative Stability
Synergistic Antioxidants: Hindered phenols + aminic agents limit viscosity increase to ≤5% after 1,000 hours at 100°C (ASTM D943), critical for compact hydraulic systems.
Hydrolytic Resistance: Maintains demulsibility (≤30 min water separation) in high-moisture environments.
- Environmental Compliance
Biodegradable components (OECD 301B) and near-zero sulfur (<0.15%)—safe for ecologically sensitive areas.
Application
Target Systems:
Mobile hydraulics (excavators, cranes).
Marine deck machinery (winches, steering gears).
CNC machine tools with servo valves.
