All hydraulic systems have a common need for protection from harmful contaminants. Good contamination control means cost effective filtration. Filtering out the particles large enough to be harmful to your system prevents damage and allows the longest possible filter service life. Minimizing maintenance costs through good contamination control practices requires proper filter application based on the specific contamination problems. If not controlled, particles too small to be seen can reduce hydraulic system efficiency.
Contamination affects hydraulic systems in many ways.
Corrosion of hydraulic systems from acids that form due to fluid breakdown and mixing of incompatible fluids in the system Increased internal leakage which lowers the efficiency of pumps, motors, and cylinders. It decreases the ability of valves to control flow and pressure accurately. It also wastes horsepower and generates excess heat. Sticking of parts due to sludge or silting. Silting is a collection of fine particles in critical areas, which will impair proper system operation.
