Evaluation of the Lubrication Properties of Biodegradable Fluids and Their Potential to Replace Mineral Oil in Heavily Loaded Hydrostatic Transmissions


Increasing public interest in the environmental impact of technical machinery has led to the development of new hydraulic fluids. In case of leakage these fluids pose less of an environmental threat than mineral oil, because they degrade faster and are less toxic or non-toxic.

The following paper describes method and results of laboratory tests with these new, so called biodegradable fluids, in a hydrostatic transmission on a flywheel restrig under high load conditions.
