Biodraulic EAL (Environmentally Acceptable Lubricant) hydraulic fluid is a premium quality, highly oxidation stable, anti-wear lubricant. This biosynthetic based product has been formulated to meet and exceed the requirements set forth by most hydraulic pump manufacturers, and is stable enough to be used in both high temperature and high pressure hydraulic systems. Even with these elevated performance characteristics, Biodraulic satisfies the criteria for ultimate biodegradability (PW1) and non-toxicity. Biodraulic has a unique rust and oxidation inhibiting system that assures the highest level of rust and oxidation protection available. It is a clear choice for use in applications on or near water. Biodraulic can be used in most applications that require an R&O or AW hydraulic fluid, and will provide environmental safety without sacrificing performance.

Biodraulic meets the definition of a bio-based lubricant as outlined in section 9001 of the Farm Security and Rural Investment Act (FSRIA) of 2002 and qualifies for preferred procurement by U. S. Federal Agencies as set forth in FSRIA Section 9002. Biodraulic complies with the “biodegradable”, “minimally-toxic” and “not bioaccumulative” standards as defined in Appendix A of the 2013 Vessel General Permit issued by the United States Environmental Protection Agency


  • Ultimate biodegradability – Biodraulic is a ASTM D5864 PW1 rated hydraulic fluid. It exhibits the highest level of biodegradability in the industry. (Ultimate >60% degraded at 28 days.)
  • Non Toxic – Passes and exceeds the acute toxicity (LC-50) criteria adopted by the United States EPA and the United States Fish and Wildlife Service.
  • Non Sheen – Biodraulic does not produce an iridescent appearance (sheen) on the surface of the water when tested in accordance with the U.S. Coast Guard Static Sheen Test (40 CFR 435 Appendix A)
  • Oxidation resistant – Oxidation inhibitors and premium quality base oils combine to form a product with outstanding resistance to oxidation and provide the maximum protection against varnish formation at both high and low temperatures. This feature will allow for drain intervals commensurate with conventional oils.
  • Provides excellent anti-wear protection – Special anti-wear, extreme pressure and friction reducing additives provide the highest level of protection against wear and scuffing in all types of vane, piston, and gear pumps used in both low and high pressure hydraulic systems.
  • Superior rust protection – Inhibitors protect both steel and yellow metal surfaces against rust and corrosion. Vastly outperforms other Bio-based fluids.
  • Demulsibility – Designed to separate rapidly from water
  • High foam resistance – Foam inhibitors provide a high level of foam resistance to prevent pump starvation and damage.
  • High viscosity index – To insure viscosity stability.
  • Superior filterability – New technology allows for better filterability and no freeze capability previously unseen in bio based fluids.


Recommended for use as a premium anti-wear hydraulic fluid in all types of vane, gear, and piston pumps and to protect against environmental issues in many industries:

  • Cities and Counties
  • Barges and Shipping
  • State and Federal Agencies
  • Irrigation Districts
  • Waste Management
  • Construction Equipment
  • Bridge Hydraulics
  • Water and Foundation Drilling
  • Elevator Service
  • Street Sweeping


Hydraulic systems are constantly subjected to adverse conditions such as water, heat, high pressures, and long operating intervals. Each of these factors affects the ability of the hydraulic system to provide maximum output when needed. Bearing, pump, valve, gear, motor and cylinder wear are very common. Gum and varnish buildup lead to poor system performance. Oil deterioration and rapid oxidation of conventional bio based fluids results not only in excessive wear, but frequent overhauls, rancid smells and poor filterability. Deterioration of seals and O-rings lead to increased oil consumption. Biodraulic hydraulic fluid is formulated to greatly reduce these problems and provide maximum environmental safety. Spill and leakage issues are a thing of the past.
