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...] about PANOLIN’s HLP SYNTH 32 is first eco-friendly hydraulic oil to obtain RDE 90235 rating

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...] about How do you size hydraulic reservoirs for aircraft hydraulic systems?
MP Filtri highlights updated in-line contamination monitor at IFPE
MP Filtri has launched its new ICM-2.0 in-line contamination monitor at IFPE, to allow users to automatically measure and display particulate contamination, moisture and temperature levels in various hydraulic fluids. Company representatives told me that the newest features of this model include the ability to download data via a USB stick with … [Read more...] about MP Filtri highlights updated in-line contamination monitor at IFPE
Why should you consider operating temperature when selecting hydraulic fluid?
Hydraulic fluid selection criteria include the expected range of operating temperatures, available means of temperature control and fluid physical properties at expected temperature levels. Where ambient and structural temperatures are above hydraulic fluid flash and/or fire points in a compartment, the potential fire hazard must be … [Read more...] about Why should you consider operating temperature when selecting hydraulic fluid?
Hydraulic tank with integrated filter
Machine manufacturers increasingly demand both functional integration within hydraulic systems and, of course, lower costs. Add to that, today’s engineers expect almost unlimited freedom when creating new designs. As a result, plastics have become an increasingly important material for constructing hydraulic tanks, according to engineers at … [Read more...] about Hydraulic tank with integrated filter
Is chemical analysis all I need to maintain my hydraulic fluid?
Often, users of hydraulic fluid will confuse a chemical analysis with a complete fluid analysis, which provides particle count of contaminants, amounts of water, and more. Oil samples that are sent off to a lab without specific instructions will return with valuable data but not all the data points you require. In most cases, the majority of labs … [Read more...] about Is chemical analysis all I need to maintain my hydraulic fluid?
What is the purpose of hydraulic fluid?
Hydraulic fluid is used in fluid power systems mainly because of its incompressibility or stiffness. This allows it to provide consistent and powerful transmission of energy throughout a hydraulic system, which allows the actuators to complete the work, whether they are linear or rotary motions. The advantage of a fluid’s compressibility ensures a … [Read more...] about What is the purpose of hydraulic fluid?
How do you quantify hydraulic fluid cleanliness?
To quantify cleanliness in any fluid power system can’t be condensed into any problem with one solution scenario. Various types of contamination occur in fluid power systems: gaseous (e.g. air), liquid (e.g. water) and solid contaminants (e.g. rust). Solid contamination is subdivided into three groups: extremely hard, hard and soft particles. … [Read more...] about How do you quantify hydraulic fluid cleanliness?

Hydraulic fluid test matches real-world conditions
Thanks to higher operating pressures, power density in many hydraulic systems has increased significantly in recent years. That can mean higher performance, smaller and lighter components and better efficiency, although it can also increase the susceptibility to wear and premature failures. Newer pumps and motors are built to handle higher loads … [Read more...] about Hydraulic fluid test matches real-world conditions
