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...]
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...]
Marine-safe hydraulic oils from Lubriplate are inherently biodegradable

Spectronic’s Oil-Glo and Water-Glo fluorescent leak detection dyes quickly find leaks
The Spectroline Oil-Glo and Water-Glo series ultraviolet fluorescent dyes are designed to detect leaks in all circulating fluid systems, including fuel, synthetic, lubricant, petroleum, water, and water/glycol-based systems. Just add a small amount of dye to the system and let it circulate. All leaks will glow brightly when scanned with a … [Read more...]
Pall Corp. launches Crixus fluid monitoring platform
Pall Corp. has announced the Crixus Fluid Monitoring Platform, a fluid cleanliness management solution designed to provide industrial customers with intelligent fluid monitoring. Pall’s Crixus fluid monitoring platform meets the growing need for lubrication and hydraulic fluid cleanliness in industrial manufacturing equipment and filter … [Read more...]
RMF Systems develops large-volume hydraulic fluid filtration solution
Most standard fitted system filters contain fiberglass filter elements, which don’t remove particles smaller than 3 micron. Within high-pressure hydraulic applications, cluttering of smaller particles can quickly result in the development of varnish, an increase of the TAN value and a significant reduction of the lubrication quality of the … [Read more...]
Quaker Chemical features fire-resistant hydraulic fluids at CHS2 International Conference
Quaker Chemical Corp. will present its fire-resistant hydraulic fluids solutions at the CHS2 Conference on Hot Sheet Metal Forming from June 4-7 in Atlanta. Hot forming operations, also known as press hardening, have all the elements of a fire hazard—900° C (1,652° F) hot surfaces, pressurized oil in the hydraulic systems, and the proximity of … [Read more...]
PANOLIN’s HLP SYNTH 32 is first eco-friendly hydraulic oil to obtain RDE 90235 rating
PANOLIN HLP SYNTH 32 is the first and so far only eco-friendly hydraulic oil to obtain the Bosch Rexroth RDE 90245 Fluid Rating List. HLP SYNTH was the first hydraulic oil to obtain the 'Blue Angel' environmental award around 20 years ago and has already been approved by numerous manufacturers. Its inclusion in the Bosch Rexroth list means … [Read more...]
How do you size hydraulic reservoirs for aircraft hydraulic systems?
Hydraulic reservoirs in a fluid power system primarily serve as a storage tanks to contain sufficient volume of hydraulic fluid and subsequently cater to the fluid demand by the pump during system operation. Additionally, the reservoirs account for the thermal expansion/contraction of the hydraulic fluid and also provide for acceptable levels of … [Read more...]
