![]() ![]() Chemical contamination is a primary reason to change your hydraulic fluid regularly. It can also happen if different hydraulic fluid types are mixed: incompatible additives may have unwanted chemical reactions. Chemical contamination arises when aging hydraulic fluid begins to degrade (oxidize) and break down.If fluids can get out, dirt can get in: never risk ignoring a leak, no matter how small! As a general rule, if you replace a hose, you should also replace your filtration and replace or flush the hydraulic fluid. Sand, silt, dust, and soot typically reach your hydraulic system through leaky seals or lack of breather filtration. Particulate contamination is responsible for much of the visible damage to final drives and hydraulic motors.Milky-looking hydraulic fluid is typically indicative of water contamination foamy fluid is most likely contaminated by air. Contamination by air- and water-borne particles can severely impact your equipment’s cycle time and performance, resulting in loss of power and reduced heat dissipation.This can mean costly repairs and replacements, impacting the return on your investment. And typically with equipment, higher pressures and tighter tolerances leave the system more susceptible to contamination and debris. 70-80% of hydraulic systems failures are attributable to contaminants in the fluid. Hydraulic fluid contamination is arguably the Achilles’ heel of any hydraulic system. ![]()
