Product Details
Hydraulic Oil Additive Package
Advanced Anti-Wear (AW) & Oxidation Inhibition Technology
Product Overview
Chemost’s Hydraulic Oil Additive Packages are formulated to provide comprehensive protection for high-pressure industrial and mobile hydraulic systems. Our technology utilizes high-quality Zinc Dialkyl Dithiophosphate (ZDDP) and sophisticated antioxidant systems to minimize pump wear, prevent valve sticking, and extend oil service life.
These packages are designed to meet or exceed major global specifications, including Denison HF-0, Eaton Vickers, and DIN 51524 Part II. They exhibit excellent filterability and thermal stability, even in the presence of water contamination.
Key Features & Technical Benefits
- Superior Anti-Wear Protection: Significantly reduces wear in high-speed, high-pressure vane, piston, and gear pumps.
- Exceptional Thermal & Oxidative Stability: Prevents the formation of sludge and varnish, ensuring clean operation and reducing downtime.
- Rapid Demulsibility & Air Release: Facilitates quick water separation and minimizes air entrainment to prevent cavitation and spongy hydraulic response.
- Excellent Filterability: Engineered to prevent filter plugging, even in the presence of water or fine contaminants (Wet/Dry Filterability).
- Multi-Metal Compatibility: Provides rust and corrosion protection for steel, copper, and bronze components within the hydraulic circuit.
Technical Specifications (Typical Data)
Chemost offers various grades, including standard Zinc-based and Ashless (Zinc-free) packages. Below are typical parameters for our core AW package.
Property | Test Method | Typical Value |
|---|---|---|
Appearance | Visual | Light Yellow to Amber Clear Liquid |
Zinc Content | ASTM D4951 | 8.0 - 10.0 wt% |
Phosphorus Content | ASTM D1091 | 7.0 - 9.0 wt% |
Sulfur Content | ASTM D129 | 15.0 - 18.0 wt% |
Flash Point (COC) | ASTM D92 | > 100 C |
Density (20 C) | ASTM D4052 | 1.05 - 1.15 g/cm3 |
Copper Corrosion (100 C, 3h) | ASTM D130 | 1a - 1b |
Primary Applications
- Industrial Hydraulic Systems: Suitable for L-HM and L-HV hydraulic fluids used in manufacturing and plastic injection molding.
- Mobile Equipment: Ideal for construction, mining, and agricultural machinery operating under extreme pressures.
- Air Compressors: Can be used to formulate high-quality R&O or AW-type compressor oils.
- General Purpose Lubrication: Applicable for lightly loaded gears and bearings where an AW-type oil is specified.
Packaging & Storage
- Packaging: Available in 200L metal drums (approx. 200kg) or 1000L IBC tanks.
- Storage: Store in a dry, cool, and well-ventilated area. Protect from moisture and direct sunlight.
- Handling: Recommended blending temperature is 40 C to 60 C. Avoid localized overheating above 70 C to maintain chemical integrity.
Frequently Asked Questions (FAQ)
Q: What industry standards does your hydraulic additive package meet?
A: Our flagship packages are designed to meet DIN 51524 Part II (HLP), ISO 11158 (HM), Denison HF-0/HF-1/HF-2, and Eaton Vickers M-2950-S/I-286-S specifications.
Q: Do you offer Zinc-Free (Ashless) hydraulic packages?
A: Yes. Chemost provides ashless hydraulic additives for environmentally sensitive areas or systems with silver-plated components where traditional ZDDP-based additives may cause issues.
Q: What is the recommended treat rate for a standard AW 46 hydraulic oil?
A: For a standard L-HM 46 hydraulic oil, the typical treat rate is 0.6% to 1.0% by weight, depending on the performance level required and the base oil quality.
Q: How does this package perform regarding "Wet Filterability"?
A: Our package includes specialized stabilizers that prevent the additive from reacting with water to form precipitates, ensuring that filters remain clear even in systems with minor water ingress.
Q: Is this package compatible with different base oil groups?
A: Yes, it shows excellent solubility in Group I, II, and III mineral oils. For synthetic formulations (Group IV/PAO), we offer specialized versions with optimized solubility profiles.
