Contamination

Harvesting reliable machinery in farming

June 2, 2025 By Mary Gannon

Mud is yet another risk to agriculture machinery’s hydraulic systems, as machines are often stored outdoors.

Agricultural machinery is up against a variety of harsh environmental conditions, so proper protection of the hydraulic systems is necessary. By Josh Cosford, Contributing Editor The agricultural industry is unique in many ways, not the least of which is the source of nourishment for billions of people, which is not something mining or forestry can […]

How do hydraulic cylinders fail—contamination

December 1, 2015 By Ken Korane

dynatect-rod-boots-web

Today’s fluid-power users, for the most part, are well aware that keeping hydraulic fluid clean is essential in preventing premature failures and unexpected downtime. Nonetheless, contamination remains a major cause of hydraulic-cylinder failure, particularly because it leads to seal failure and leaks. And it can come from several different and unexpected sources. Internal contamination is […]

What is hydraulic fluid conditioning – part 3

October 20, 2015 By Josh Cosford

Your oil is wet. No, I didn’t skip 8th grade science class, where you learn how oil and water don’t mix. Okay, so it mixes a bit, if you agitate it enough, but then separates nicely with oil floating atop water. Your hydraulic fluid likes water as much as olive oil likes a bottle of […]

What is hydraulic fluid conditioning – part 1

August 6, 2015 By Josh Cosford

Hydraulic-fluid

  You’ll have to excuse my shade of indigo. I’m not sure if it’s more Smurf or Na’vi, but back when I first started writing about fluid power, I promised I’d talk about fluid conditioning until I’m blue in the face. I’ll live with the odd skin tone, because fluid conditioning is still one of […]

Reliable Plant exhibition focuses on industrial fluid systems

April 24, 2015 By Mary Gannon

Reliable-Plant

Clean, dry hydraulic fluid is the lifeblood of any hydraulic system. And keeping all gear oils, lubricants and other fluids within an industrial system contaminant-free is critical to efficient and reliable machinery. That’s why there is an entire trade show and technical conference dedicated to these technologies each year, called Reliable Plant, sponsored by Noria […]

Why the ISO code matters

November 17, 2014 By Josh Cosford

Earlier this month, I explained the meaning behind the ISO 4406 contamination code, so now I’m explaining why it matters, and how you can apply it to your application. The code describes the quantity of 4-, 6- and 14 -μm particles in a milliliter of hydraulic fluid—because these particle sizes are considered the most damaging […]

Understanding ISO 4406

November 7, 2014 By Josh Cosford

The most critical quality of hydraulic fluid you should consider is that of cleanliness. We refer to the size and quantity of particle contamination when discussing cleanliness, and so that we are all on the same page, standards were created for measuring and expressing this quality. Although the standard for oil cleanliness has changed over […]
