New synthetic hydraulic fluids for maritime applications

Reliable and readily biodegradable products reduce impact on sensitive eco-systems

New synthetic hydraulic fluids for maritime applications

Non-toxic, readily biodegradable speciality lubricants can make a sizable contribution to protecting the seas

In hydraulic systems leakage is a particularly frequent phenomenon that has not been sufficiently solved to date. The root cause lies with the numerous flexible connections within a hydraulic system that are subject to wear or can be damaged due to external mechanical stress. They are constantly under pressure and hard to seal completely even with the best of maintenance. The specific technical requirements of complex hydraulic systems are such that until recently they could often only be met by fluids based on mineral oils. With the development of the Klüberbio LR 9 series, however, Klüber Lubrication has succeeded in creating a synthetic, readily biodegradable product offering a performance that is at least equal to that of mineral oil based products.

“The new, highly efficient hydraulic fluids of the Klüberbio LR 9 series bear the European Eco Label issued for particularly eco-friendly products. They contain more than 90 % of renewable resources”, explains Dirk Fabry, Market Manager Maritime and Offshore Industry at Klüber Lubrication. “They are readily biodegradable and not toxic to marine organisms, which considerably reduces their environmental impact in the event of a leakage.”

High performance even under strongly varying temperatures
Due to their very good viscosity-temperature behaviour and low setting point, Klüberbio LR 9 oils help hydraulic systems get easily started even at low temperatures. They can therefore be used even where temperatures fluctuate considerably. As they are very resistant to hydrolysis, they enable longer oil change intervals and better reliability of the hydraulic system also in wet environments. The synthetic ester based oils are specially designed for applications in mobile hydraulic systems in the marine and offshore sectors. They are also products of preference for land-based hydraulic applications in ecologically sensitive environments, for example in hydroelectric power plants or waterway locks.

The biodegradability of the oils is over 60 percent after 28 days. In addition, they meet or even exceed the minimum requirements according to ISO 15380, Bosch Rexroth RE 90221-01 and Swedish Standard SS 15 54 34.
