Bio-Ultimax™ 1500 Hydraulic Fluids

A specially formulated, ultimately biodegradable1 product designed specifically for use in hydraulic equipment operating over a wide range of temperatures and where an oil with high dielectric (>35 KV) insulating property is required.  Applications include power utility aerial lift buckets, mobile and stationary hydraulic systems, or other equipment where electrical insulating safety is preferred.  Bio-Ultimax 1500 Hydraulic Fluids are formulated to perform in hydraulic systems that require Anti-Wear (AW), anti-rust, anti-oxidation, anti-foam, and demulsibility properties.  They are highly inhibited against moisture and rusting in both fresh and sea water and passes both A and B Sequences of the ASTM D-665 Turbine Oil Rust Test.  Incorporating the super high viscosity index of the Stabilized* High Oleic Base Stocks (HOBS) into the formula, increases the viscosity index past synthetic levels (Energy Conserving Formulas).  A zinc-free additive system has also been developed that is environmentally friendly and meets or exceeds pump requirements.

Bio-Ultimax™ 1500 Hydraulic Fluids are designed for use in mobile and stationary hydraulic vane, piston, and gear-type pumps and has shown exceptional anti-wear performance.  Very little wear was encountered, 0 to 25mg (Pass), in accelerated biobased tests using Denison T-5D, Vickers 20VQ, 35VQ-25 (M-2950-S), and V-104C (ASTM D-2882),  Vickers I-286-S, pump stand tests at pressures and temperatures ranging from 2000 to 3000 psi and from 1500 to 2100 F.  The anti-wear performance exceeds the load stage 10 in the FZG (DIN 51354) requirements for US Steel 136, 126, and 127, DIN 51524 Part 2 and 3, and GM (LS-2).  It also meets the requirements for ashless GL-3 gear oils in reduction units and gear sets where it meets the viscosity range.

Bio-Ultimax™ 1500 Hydraulic Fluids meet the Environmental Protection Agency (EPA) 2013 Vessel General Permit (VGP) guidelines for Environmentally Acceptable Lubricants (EALs), and should be used in hydraulic systems where LOW TOXICITY, BIODEGRADABILITY and NON-BIOACCUMULATION properties are required. They exceed the acute toxicity (LC-50 / EC-50 >1000 ppm) criteria adopted by the US Fish and Wildlife Service and the US EPA. Because they meet the environmental requirements they can also be used where ISO 15380 (HEES/HETG) Hydraulic Fluids are specified. Bio-Ultimax™ Hydraulic Fluids are ENVIRONMENTALLY ACCEPTED LUBRICANTS (EALs) that are formulated from renewable biobased resources. We believe Earth’s environmental future rests in the use of renewable materials.

The test data below show that the Bio-Ultimax™ 1500 Dielectric Hydraulic Fluids provide high performance in a wide variety of stationary and transportation equipment, that operate in broad ranges of environmental conditions. In equipment operating outside, wear from poor cold temperature pumpability, surge loads, moisture, and dusty environments are more prominent. Bio-Ultimax™ 1500 Dielectric Hydraulic Fluids are formulated to improve performance in equipment that requires excellent anti-wear, demulsibility, and cold temperature pumpability as low as -40℃. They meet and exceed ISO 11158 HV and have Genie-Terex and Altec Equipment OEM approvals.
