Hydraulic Fluids

Leading technologies in hydraulic oil additives

Hydraulic systems must provide tough, unyielding power in the harshest environments, and they rely on hydraulic fluid to protect crucial components from wear and corrosion.

Today, hydraulic systems have become more compact, resulting in higher pressures, smaller lines, smaller reservoirs and more critical fluid controls. As a result, it is important to use a quality hydraulic fluid package that will ensure optimum performance.

Lubrizol’s high performing hydraulic fluid packages are designed to provide peak hydraulic system performance for both stationary and mobile hydraulic systems, with benefits that include:

  • Resistant to varnish
  • Better oxidation resistance
  • Better anti-foam characteristics
  • Improved air release properties
  • Improved thermal stability
  • Extended anti-rust performance
  • Increased extreme pressure
  • Excellent anti-wear performance
  • Improved filtration

Lubricants for hydraulic systems are selected according to several factors: operating conditions such as load, speed, and temperature, as well as any special requirements for the type of end use application of the hydraulic system:

Heavy-duty construction equipment faces many challenges, from harsh outdoor environments with fluctuating temperature ranges, to the potential for dirt or water contamination, to heavy loads, to extended periods of off-season storage

Varnish, contamination and changes to lubricant viscosity will eventually impair the performance of critical components, increasing downtime and maintenance costs.

High performing hydraulic fluid technology keeps the oil clean and free from contaminants to maintain equipment productivity and uptime.

Lubrizol offers a wide range of incidental food contact lubricants to meet the increasingly stringent demands of the food processing industry. We are well established in incidental food contact lubricant manufacturing, and can provide customized blending, packaging and private label services.

The Lubrizol product family of incidental food contact additives and fluids can help you reduce development costs, simplify your operation and improve supply logistics. This complete range of food processing products includes components, packages and blended fluids – with NSF Registration, CFR 21 Section 178.35790, NSF HX-1.

Forestry equipment must be able to consistently perform in harsh outdoor environments with fluctuating temperature ranges, under heavy loads, with constant threat of contamination from water or dirt particles. Varnish, contamination and changes to lubricant viscosity will eventually impair the performance of critical components, increasing downtime and maintenance costs.

In order to obtain the longest possible service from a hydraulic oil, it is important to keep the oil clean and free from contaminants. This applies not only to the time that the oil is actually being used, but also during storage and installation.

Equipment used in mining operations must be able to perform consistently in harsh environments with fluctuating temperature ranges and heavy loads. Contaminants and changes to lubricant viscosity will eventually impair the performance of critical components in a hydraulic system, increasing downtime and maintenance costs.

Lubrizol offers a complete line of hydraulic oil additives and packages to keep engines running cleanly and more consistently. Our high-performance hydraulic fluid additives enable viscosity modification, reduce air entrainment and help combat the effects of contamination with wear protection, thermal stability, rust and corrosion protection, and excellent hydrolytic stability properties that will extend the life of your customers’ oil and systems.

Plastic injection molding operations – run by large hydraulic systems – often suffer from high maintenance costs and downtime due to contaminants in the oil. Typically, the cause is varnish build-up, which impairs the performance of critical components and affects system productivity.

Lubrizol’s high performing hydraulic fluid additive technology is designed to remove varnish from the hydraulic system and then keep varnish components from depositing. As a result, injection molders benefit from increased productivity, extended fluid life and reduced valve replacement and the associated downtime.

One large injection molder* reduced downtime for cleaning from 48 hours to 1 hour with Lubrizol’s hydraulic clean technology. This produced superior results – including a $14,100 annual labor savings, $44,139 production savings per year per machine, and increased part production through shorter cycle times for an annual savings of $703,200.

*Case study based on 50 machines. Savings based on cleaning 20% of the machines per year using Lubrizol’s technology.

In demanding steel mill environments, equipment must withstand rigorous use and extremely high temperatures. As a result, hydraulic oils must be equally tough – able to prevent wear and corrosion and, in many cases, have fire-resistant properties.

Lubrizol offers a complete line of additives to meet these needs. Our technology keeps fluids clean, eliminating varnish build-up and other contaminants that hamper productivity. In addition, other additive products are available to ensure excellent hydrolytic stability, superior rust and corrosion protection and minimal increases in air entrainment. We also offer an invert emulsion that is Factory Mutual-Approved for fire resistance.

Lubrizol offers a complete line of hydraulic oil additives and packages that keep systems running cleanly and more consistently. What’s more, Lubrizol backs all of our hydraulic fluid additives with decades of formulating experience and proven field performance.

We can help you formulate hydraulic fluids to meet Parker Hannifin France (Denison) HF-0, Bosch Rexroth and Poclain requirements – with wear protection, thermal stability, rust and corrosion protection, and anti-wear properties that will extend the life of your customers’ oil and hydraulic systems.
