SINOPEC Environmentally acceptable synthetic hydraulic oils
L-HM Ashless hydraulic oils are designed to give maximum protection in hydraulic equipment used on vessels and in environmentally sensitive areas. They are used in hydraulic systems as recommended by ISO 15380, HEPR in mobile and stationary hydraulic vane-, piston-, and gear-type pumps.
They have a high viscosity index, which ensures good temperature fluidity for low-temperature operations. They are formulated with synthetic base stock and an ashless, zinc-free additive system that provide exceptional oxidation stability, water separability, foam suppression, and protection against wear, rust and corrosion. The synthetic base stock withstands oxidation at high operating temperatures and results in maximum service life for the oil relative to vegetable-based readily biodegradable products.
They meet the requirements of the EPA Vessel General Permit (VGP) for biodegradation, low toxicity and low bioaccumulation.
