Problems that crop up in hydraulic systems are often caused by contaminants like dirt and water in the oil that lead to corrosion, wear and premature failure. But many performance problems are due to another contaminant: varnish that coats control valves, restricts filters, and fouls reservoirs and other internal parts. Most hydraulics users are … [Read more...] about What is the Varnish Potential Rating?

Lubrication issues in industrial hydraulics
Without adequate lubrication, hydraulic components will fail, falling victim to excessive friction, heat, particle contamination and more. By Josh Cosford, Contributing Editor Hydraulic fluid is a multi-talented medium bringing more to the plate than just the transfer of force. Hydraulic fluid also helps with cooling, contamination … [Read more...] about Lubrication issues in industrial hydraulics

They are available in ISO … [Read more...] about Biodegradable anti-wear hydraulic fluids for environmentally sensitive areas
What is the “toast” test?
An important characteristic of many hydraulic fluids is the ability to maintain performance at high temperatures. Higher temperatures can cause oxidation—the reaction of the fluid and its constituents with oxygen. The rate of reaction accelerates as temperature increases, as does the presence of catalyst metals like copper and iron, especially at … [Read more...] about What is the “toast” test?
What functions do hydraulic fluids perform in a system?
Contributed by Carl Dyke, CD Industrial Group Hydraulic fluid is the energy transfer medium in all hydraulic systems. This simple function is only achieved by a fluid that does not easily trap gasses. Trapped gas and foaming problems would bring a higher level of compressibility to a fluid that is usually relied upon to support a very stiff, … [Read more...] about What functions do hydraulic fluids perform in a system?
