solutions are completely oil-free and more environmentally friendly in general. High Water Based Fluids (HWBF) fluids have the same viscosity as water and may only be used between +5°C and +55°C. They have no [...] Fire-resistant fluids based on water with 2 to 5% concentrate intended to give the water a minimum level of protection against corrosion and wear. Depending on the composition of the concentrate, emulsions [...] each case and the respective user is responsible for mixing the concentrate in. "Thickened water" fluids based on HWBF whereby certain polymers ("water thickeners") are molecularly dispersed in water at

Within a larger system several loads (drive elements) are supplied by one drive power pack. The fluid power system with main pipe can combine such loads, which do not interact, because e.g. they come in

hydrostatic load-bearing layer it is applied from the exterior. The fluid friction is produced in both cases by the internal friction in the fluid that forms the load-bearing layer (DIN 50 281).

Biodegradable fluids are hydraulic fluids that biodegrade significantly more quickly than mineral oils. Biodegradation is a chemical conversion caused by microorganisms under aerobic conditions in an [...] freedom from hazardous substances are important criteria for the environmental aspects of a hydraulic fluid.

Concerned with the physical characteristics and behaviour of fluids at rest (hydrostatics) and when moving (hydrokinetics)

Resistance of a liquid to permanent changes of its properties in normal storage and load conditions (CETOP RP 100).

Characterises the chemical composition as well as the physical state of a new hydraulic fluid . Here is must be noted that even new oil is never absolutely clean, instead on average it corresponds to filter

To monitor the state of a hydraulic fluid there are three variations, each with a different information value: Visual inspection : The colour of a pressure fluid (in particular mineral oil) is a measure [...] measure of its ageing. However, this is very inaccurate, as a black discolouration of the fluid alone does not necessarily affect its usability in any way. Quick analysis in operations : Ongoing control using

Distance that is required to form from a turbulent a laminar flow and vice versa. The formation of a laminar flow requires a significantly greater distance.

People would be perfectly happy to work with just one type of oil in mobile hydraulics, i.e. using the same oil in the both the engine and the hydraulics. This, however, is not advisable from either a
