Alpha-Web media technology provides up to four-times cleaner hydraulic fluid
Donaldson Company Inc. has released Alpha-Web filtration media. This new hydraulic filtration technology significantly improves hydraulic fluid cleanliness which can extend hydraulic component life, decrease downtime and lower the cost of equipment ownership. Filters must stand up to the challenge of maintaining fluid cleanliness … [Read more...] about Alpha-Web media technology provides up to four-times cleaner hydraulic fluid
Hydraulic filters continue to evolve
By Josh Cosford, Contributing Editor The evolution of hydraulic filters from basic, pleated cellulose or paper into today’s synthetic depth media material has been slow but sure. This is because there are only so many ways to trap microscopic particles while offering little resistance to even smaller oil molecules. But engineers are continuing the … [Read more...] about Hydraulic filters continue to evolve
Sustainability drives hydraulic seal design
Sustainability continues to trend across the fluid power industry, as design engineers must develop more efficient products to meet the industry’s sustainability needs. Hydraulic seals, though relatively small in design, play a huge role in waste, emissions, efficiency, and overall environmental impact. At IFPE, companies such as Hallite … [Read more...] about Sustainability drives hydraulic seal design
Why should you use return filters in your hydraulic system?
By Josh Cosford, Contributing Editor The venerable return filter is just as crucial to your hydraulic system as your kidneys are to your body. Could your hydraulic system survive with no return line filter? Sure, I suppose in the same way you could survive without kidneys if you strapped on the dialysis machine for five hours a day a few times a … [Read more...] about Why should you use return filters in your hydraulic system?
Why modern equipment can benefit from higher-performance hydraulic fluids
Today’s hydraulic fluids are forced to operate in hotter environments. But the right formulation can help reliably moderate temperatures, creating significant operational benefits for end users. By Blayne McKenzie, Technology Development Manager, Industrial Products, The Lubrizol Corp. Mobile and stationary hydraulic systems have gone through … [Read more...] about Why modern equipment can benefit from higher-performance hydraulic fluids
What is the best cylinder piston seal?
By Josh Cosford, Contributing Editor How long is a piece of string? So what? Did you think you'd get a straight answer on a subject like "what is the best cylinder piston seal?" There is no best piston seal, just like there is no best car (it's the Mazda Miata, by the way). If you're in the snow belt with five kids, your best car is a … [Read more...] about What is the best cylinder piston seal?
What to consider when using TPU for fluid power seals
Contributed by Chuck White, Director of Sales & Marketing, Hallite Thermoplastic Polyurethane (TPU) is widely used in fluid power seal applications and is a family of polymers formed using a combination of isocyanate and polyol crosslinked to create a homogeneous compound polymer. There are many different combinations of these chemicals that … [Read more...] about What to consider when using TPU for fluid power seals
When should you use desiccant breathers?
By Josh Cosford, Contributing Editor Hydraulic systems are susceptible to many forms of contamination – particles, heat and water. When each of these contaminants is kept in check, there is no reason your hydraulic oil cannot last indefinitely, all the while providing conditions for a reliable hydraulic system. Water is an especially interesting … [Read more...] about When should you use desiccant breathers?
When are EPDM seals appropriate in hydraulic systems?
EPDM rubber is a synthetic polymer used in fluid power applications to seal static applications, such as pump housing seals or cylinder barrel end seals. Although rarely used as a dynamic seal for hydraulic applications, EPDM has benefits making it perfect for various applications. EPDM stands for ethylene propylene diene monomer and offers a … [Read more...] about When are EPDM seals appropriate in hydraulic systems?
