Hydraulic oils are specially formulated to resist changes in volume and viscosity to keep hydraulic systems running efficiently, even when subjected to adverse and harsh conditions. Also known as hydraulic fluid, these oils power hydraulic systems by creating a pushing force to move parts of the system. Hydraulic oils also lubricate the system to reduce friction between moving parts and help prevent wear and tear on them. Hydraulic oils are used in a variety of equipment, such as jacks, doors, lifts, brakes, forklifts, tractors, and snow plows.
When looking to purchase hydraulic oil, people often ask:
AW 32 Hydraulic Oil? AW 46 Hydraulic Oil? AW 68 Hydraulic Oil? ISO 32 Hydraulic Oil? ISO 46 Hydraulic Oil? ISO 68 Hydraulic Oil? Which hydraulic oil is the right one for me?
It’s no industry secret: Choosing the right hydraulic oil means a smoother ride for your equipment. One of the best ways to run your hydraulic systems smoothly is to use the right hydraulic fluid. A proper hydraulic oil analysis of your specific needs by an experienced and trusted expert can ensure that your equipment is running at peak performance for as long as possible. Whether you’re looking for just the right tractor hydraulic oil, forklift hydraulic oil, Bobcat hydraulic oil, or Kubota hydraulic oil, you need the best product to do your best work. Making the right choice when it comes to your hydraulic oil can extend the life of your equipment.
Hydraulic oils can meet any challenge!
Hydraulic systems that operate high-speed, high-pressure hydraulic pumps are common in today’s world. Hydraulic oils are available in a wide range of grades to meet these and many other critical machinery challenges. Some applications require hydraulic fluids that conform to the vigorous standards of the equipment’s original manufacturers. Other hydraulic applications require lubricants with low-temperature properties and high dielectric strength for protective insulation.
Hydraulic fluid can be the most vital component of a hydraulic system, so you must carefully consider dozens of characteristics before making a final selection. Choosing the best hydraulic oil requires a basic understanding of each particular fluid’s characteristics in relation to other available options. We at Turpin Wholesale can help you make your best choice, taking into account the properties of a hydraulic fluid, including thermal stability, hydrolytic stability, chemical corrosiveness, anti-wear characteristics, tendency to cavitate, longevity, water rejection, constant viscosity, and cost.
While no single fluid may be ideal in every category, with the help of Turpin Wholesale it is possible to select one that is the best fit for a particular hydraulic system or task. This selection requires knowledge of the system in which a hydraulic fluid will be used. We can discuss the important factors guiding your hydraulic oil selection, including:
Viscosity – Maximum and minimum operating temperatures, along with the system’s load, determine the fluid’s viscosity requirements. The fluid must maintain a minimum viscosity at the highest operating temperature. However, the hydraulic fluid must not be so viscous at low temperature that it cannot be pumped.
Foaming – When foam is carried by a hydraulic oil, it degrades system performance and therefore should be eliminated.
Rust & Oxidation – Most hydraulic fluids need rust and oxidation inhibitors. These additives both protect the metal and contain anti-oxidation chemicals that help prolong fluid life.
Corrosion – Two potential corrosion problems must be considered: system rusting and acidic chemical corrosion. System rusting occurs when water carried by the fluid attacks ferrous metal parts. Most hydraulic oils contain rust inhibitors to protect against system rusting. To protect against chemical corrosion, other additives must be considered. The additives must also exhibit good stability in the presence of water (hydrolytic stability) to prevent breakdown and acidic attack on system metals.
Oxidation and thermal stability – Over time, fluids oxidize and form acids, sludge, and varnish. Acids can attack system parts, particularly soft metals. Extended high-temperature operation and thermal cycling also encourage the formation of fluid decomposition products. Hydraulic oils should have additives that exhibit good thermal stability, inhibit oxidation, and neutralize acids as they form.
Water retention – The right choice of hydraulic fluid can ease the strain on a system’s pumps and filters.
Temperature – System operating temperature varies with job requirements. The proper hydraulic oil can withstand higher temperatures longer, resulting in better performance and less frequent oil changes.
Fluid makeup – Most hydraulic oils are evaluated based on their ratings for rust and oxidation (R & O), thermal stability, and wear protection, plus other characteristics that must be considered for efficient operation.
Seal compatibility – The hydraulic oil selected should be checked to be sure that the fluid and seal materials are compatible, so the fluid will not interfere with proper seal operation.
