Hydraulic Oils for Mobile & Stationary Applications

Right hydraulic oil provides smoother ride for your equipment

It's no industry secret: One of the best ways to run your hydraulic systems smoothly is to use the right hydraulic fluid. Lubrication Engineers offers a full line of multifunctional hydraulic oils, including several 100 percent synthetic formulations, all of which outperform conventional hydraulic fluids. They provide superior rust prevention, water separation ability, high film strength and excellent handling under extreme pressure. They ensure smooth transition of power and protect metal surfaces from corrosion.

LE hydraulic oils can meet any challenge

Hydraulic systems that operate high-speed, high-pressure hydraulic pumps are common in today's world. LE's hydraulic oils are available in a wide range of ISO and SAE grades to meet these and many other critical machinery challenges. Some applications require hydraulic fluids with R & O properties that conform to the vigorous standards of the equipment's original manufacturers. Other hydraulic applications – such as the bucket trucks that provide electrical service for urban electric grids – require lubricants with low-temperature properties and high dielectric strength for protective insulation.LE's hydraulic oils offer an array of impressive characteristics to meet these varying standards.

Some of these oils feature high resistance to consistently elevated, turbine-grade temperatures. Others (such as those used for food processing and packaging) need to meet NSF H1 requirements for incidental food contact or meet the USDA H2 criteria for nonfood contact areas of food processing and packaging plants. Still other hydraulic fluids must provide heavy-duty performance in an environmentally friendly formula – in applications such as flood control structures, offshore installations, locks on rivers, dredging equipment and other environmentally sensitive applications. LE's comprehensive line of hydraulic oils is designed to accommodate diverse lubricant needs.


Look for products that contain Monolec

Monolec

Monolec®, LE's in-house wear-reducing additive, creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances, and allowing for opposing surfaces to slide by another. The result is greatly reduced friction, heat and wear. This is of great benefit for mobile and stationary hydraulic systems, such as construction equipment and utility service boom trucks.

Fire Resistant Hydraulic Oil

Firesafe™ PoE Hydraulic Fluid (9455)

Hydraulic Oil FM Approved

Designed to replace standard hydraulic fluids in applications with fire hazard potential, Firesafe PoE Hydraulic Fluid is an FM Approved® fire-resistant product. It is recommended for applications where the possibility exists for the fluid to come in contact with an ignition source or where operating temperatures could exceed the fire point of a standard hydraulic fluid. Firesafe PoE is formulated with a higher fire point than traditional hydraulic fluids, and will not propagate a flame from an ignition source. It will enhance safety, instill confidence and reduce insurance costs in plants. Unlike many competitive products, it contains no water, so it will not cause rust and corrosion, and will be less susceptible to microbial attack. It is a readily biodegradable formula containing no toxic ingredients – making it suitable for use in environmentally sensitive applications.

Typical Applications: Mobile and stationary equipment that call for an anti-wear hydraulic fluid, including hydraulic systems, circulating systems and chains. Recommended industries include steel mills, foundries, mining, and glass manufacturing.
