Filtering Out Hydraulic Problems

How clean is your hydraulic fluid? Almost never as clean as you think, and as a recent Hydraulics & Pneumatics article posted to our LinkedIn page notes, it’s the age-old problem of enough maintenance vs. too much maintenance. Getting this issue wrong can have serious consequences.

“Most contamination particles in hydraulic fluid are too small to be seen by the naked eye, which is why contamination-monitoring instruments are important for maintaining high system reliability,” writes article author Justin Bitner, a product specialist at Eaton. “While users of industrial hydraulic systems have dealt with this issue for some time, it has only recently come to the fore in the mobile world, where spin-on filters and time-based fluid maintenance are still commonly found. Neither of those technologies, however, is sufficient to protect today’s high-pressure, high-performance mobile hydraulic systems.”
