The performance of all hydraulic fluids in general, and water glycol hydraulic fluids specifically, is dependent on both fluid cleanliness and fluid composition. In fact, fluid cleanliness (and contamination) can exhibit dramatic increases in pump wear, even for new fluids, if inadequate filtration is used or if contamination occurs. Since fluid composition can also similarly affect war rates, it is also essential that compositional changes during use be minimized. The impact of improper fluid maintenance on hydraulic fluid performance will be discussed and recommended fluid maintenance procedures for water-glycol hydraulic fluids will be provided.
