Particles and water lead to a high degree of contamination and accelerate oxidation processes and additive consumption. This affects viscosity, lubricating film thickness, shear forces, air separation capacity and the wear protection properties of the hydraulic oil – important oil condition values that decide on an oil change. Particles and water in the oil, followed by oil ageing and choosing the wrong type of oil, are considered the critical few causes that cause the most damage. They cause abrasive wear, fatigue wear, corrosion, cavitation, varnish, sludge- and resin-like deposits (valves, main flow filters, tank, pipelines, etc.) and lead to acidification of the oil and thus to further corrosion. A vicious circle.
The cleaner and drier the hydraulic oil, the more stable the oil condition values and longer the oil life — and the longer the service life of components
