Green A/W Oils anti-wear hydraulic oils are for use in high-pressure pumps and gears in environmentally sensitive areas. They are aromatic-free, inherently biodegradable and will pass the U.S. Coast Guard static sheen test. They are nontoxic to aquatic life. They offer high thermal and oxidative stability, exceeding 15,000 hr D 943 TOST Life. Four grades — 22, 32, 46, and 68 — have viscosity indexes of 110, 106, 104, and 102, respectively.
Clarion Lubricants, (800) 249-4684, bit.ly/HP511ClarionFluid
Cosmolubric B-230 is a vegetable oil-derived fluid formulated with additives to enhance corrosion protection, metal passivation and oxidative inhibition. It is preferred over mineral oil-based fluids because it resists ignition and is less flammable in the event of a hydraulic line rupture. It is readily biodegradable, approved by Factory Mutual as a less hazardous fluid, and listed as BioPreferred by the USDA.
Houghton International Inc., (610) 666-4000, bit.ly/HP511HoughtonFluid
DuraClean ISO 46, all-season premium hydraulic oil features an additive chemistry that keeps deposits from settling on components, thus maximizing oil life and providing anti-wear protection. It allows for rapid air release and water separation, and provides high shear stability. Acrylate anti-foam agent contains no silicones, which can lead to inaccurate particle counts. It has a viscosity index of 141.
Parker Hannifin, Hydraulic Filter Div., (419) 644-4311, bit.ly/HP511ParkerFluid
Food-grade synthetic hydraulic oils are blended from premium polyalphaolefin (PAO) base oils with additives for the food industry. They are NSF H1 registered and are multi-purpose oils for use in industrial applications as well as hydraulic systems. Two grades — 46 and 68 — have viscosity indexes of 127 and 141, respectively. They reduce varnish and deposit build-up and offer a low evaporation rate while operating in a wide temperature range.
CRC Industries, (800) 272-4620, bit.ly/HP511CRCFluid
EnviroLogic 3000 series hydraulic fluids are high performance, readily biodegradable, and non-hazardous. They are intended for severe service, extreme temperatures ranging from –40° to 400°F, and high pressures. They are formulated from non-toxic base stocks that offer high oxidation and thermal properties, providing enhanced wear protection, cleanliness and long life. Four grades — 32, 46, 68, and 100 — have viscosity indexes of 190, 178, 176, and 174, respectively.
Terresolve, (440) 951-8633, bit.ly/HP511TerresolveFluid
DTE 10 Excel series lubricants are shear stable, high-viscosity-index fluids with a zinc-free, anti-wear system for use in modern, high-pressure industrial and mobile equipment hydraulic systems. They can keep systems cleaner, longer and improve energy efficiency, extend oil and equipment life, and reduce operational costs.
Mobil Industrial Lubricants, (800) 662-4525, bit.ly/HP511MobilFluid
Super Hydraulic Oil 46 is a premium antiwear hydraulic oil with a very high viscosity index for use in all seasons. It provides high anti-wear properties, rust protection, low deposit formation, good demulsibility, oxidation resistance, good anti-foam properties and fast air release properties. It helps reduce vane and gear pump wear and offers a viscosity index of 163.
Volvo Construction Equipment, +44 (0) 1223 836636, bit.ly/HP511VolvoFluid
Dimension hydraulic fluid is an ashless fluid made with synthetic base stocks and additives, offering high resistance to sludge formation, chemical stability, and anti-wear protection. It is designed for use in vane, piston, and gear pumps. Two grades — 46 and 68 — offer viscosity indexes of 131 and 135, respectively. High oxidation stability provides extended drain and filter change intervals.
