hydraulic oils

Today, hydraulic pumps are smaller, more complex, and are required to handle higher flow rates, pressures and temperatures. Oronite has developed solutions to improve the reliability and performance of modern hydraulic equipment for a wide range of applications.

Our anti-wear hydraulic oil additives meet the performance 

standards of the best hydraulic equipment manufacturers in the world.

Besides extensive laboratory testing, our technology development involves real-world testing, including regular exchanges, product validation and approvals with key original equipment manufacturers (OEMs) such as Denison® and Eaton Vickers®.

trends in hydraulics

complex hybrid pumps

Significant increases in pump discharge pressures and simple designs giving way to complex hybrid pumps.

higher oil temperatures

Smaller oil sumps with higher flow rates resulting in shorter residence time in the tank and higher oil temperatures.

performance attributes

In addition to meeting global hydraulic performance specifications, Oronite additives also offer system reliability by using formulations which prevent wear, valve sticking, metal transfer and filterability issues. Our hydraulic oils can handle more demanding duty cycles such as continuous production or continuous service of leased equipment. And you'll find our products provide resistance to higher operating temperatures as well as applicability and adequacy in a wide variety of base oils. This is how Oronite hydraulic oils add up for you.
