Frequently Asked Questions

What viscosity grades are available for this hydraulic oil?
This high-performance hydraulic oil is available in ISO VG 32, ISO VG 46, and ISO VG 68 viscosity grades.
Does this oil support operation under extreme temperatures?
Yes. With a Viscosity Index (VI) greater than 140, it is engineered to ensure stable and reliable operations across a wide temperature range from -30°C to 100°C.
Is this formula safe for system components containing bronze?
Absolutely. It utilizes an ashless formula that yields zero copper corrosion (1A rating per ASTM D130), making it perfectly safe and highly recommended for axial piston pumps containing bronze components.
Which industry standards does this hydraulic oil conform to?
This oil conforms to major industrial specifications including GB 11118.1-94, DIN 51524-3, and Denison HF-0.
How does this product improve system efficiency and service life?
It extends pump life by 30% in vane pump applications, achieves up to 5% energy savings due to reduced friction, and doubles your service life via a synthetic antioxidant system that provides 3000+ hours of oxidation stability.
What packaging volume options do you offer?
We offer three primary packaging options: 20L sealed pails (UV-resistant), 205L steel drums (with protective nitrogen blanketing), and 1000L IBC totes for high-volume users.
