By Josh Cosford, Contributing Editor It was 20° here in Burlington, Ontario yesterday. No, not 20° Fahrenheit, but 20° Celsius … equating to something like 68° F. Nevertheless, it was warm enough to have our entire family outside playing basketball in the driveway. Because of the weather and the lack of human gatherings, I’m seeing a number of … [Read more...]
How does hydrolysis affects seals?
Literally, every fluid power system counts on soft-sealing technology to contain high-pressure liquid, allowing hydraulic energy to transmit useful work. The most common rubber technology in today’s fluid power system is synthetic, such as Buna nitrile or urethane. Each type of polymer has its advantages, but they also differ in their … [Read more...]
Low-pressure filters feature unique box geometry for longer life
MP Filtri will be highlighting its new ELIXIR low pressure filters at IFPE 2020 next month. The new designs are rated to 232 psi, are lighter, easy to use and kinder to the environment. They include inline connections, zero leakage bypass valve and cartridge style element and reusable bowl and suction, return and supply line configurations with … [Read more...]
Offline filtration loop adapters ensure clean reservoir fluids
When hydraulic systems need to be cleaned, there’s no easy way to access the fluid inside reservoirs. As any user of fluid power knows, new and used hydraulic fluids typically are not pre-filtered and can be highly contaminated. One-pass filtration systems aren’t enough. Opening the filler breather cap while filling the reservoir allows airborne … [Read more...]
5 common failures of hydraulic cylinder seals
Contributed by James Czegledi, Engineering manager, Peninsular Cylinders It can happen at anytime, most often without notice — your cylinder has failed. More often than not the failure can be attributed to a seal or seals used inside of the cylinder. Let’s take a look at the types of seals typically found inside a hydraulic cylinder. Piston … [Read more...]
Hydraulic tank design is a HIT
The Hybrid Integrated Tank offers a cost-effective upgrade for mobile hydraulic systems. Hydraulic tank systems for mobile equipment must be crafted to handle diverse and multifaceted requirements. OEMs often take a do-it-yourself approach: purchase individual components such as tanks, filters, connectors, breathers and oil level indicators, … [Read more...]
Ultra-low temperature FKM sealing materials
Greene Tweed’s Fusion FKM 665 sealing material is a new generation, ultra-low-temperature and chemical-resistant elastomer, that was specifically formulated to meet and exceed the requirements of Aerospace Material Specification (AMS) 7379 and AMS-P-83461. With a temperature range of –70° to 450°F (–57° to 232°C), Fusion 665 achieves outstanding … [Read more...]
Shroud strengthens visual pop-up indicators on filters
Schroeder Industries has released a protective shroud for the D5 series visual pop-up indicators. This shroud protects D5 indicators against harsh environments and inadvertent impacts that cause indicator cracking/breakage. Visual pop-up indicators provide an economical way to know (at a glance) when a filter element needs to be replaced. With … [Read more...]
A review of hydraulic fluids and contamination control
It’s critical for equipment manufacturers and the engineers they employ to possess a sound understanding of the composition of oils, the properties of lubricants, and how hydraulic fluids can impact machine performance. With that fact in mind, IFPE 2020 will offer attendees an education session entitled “Hydraulic Fluid Properties, Efficiency … [Read more...]
More desiccant and increased airflow means longer life for breathers
Des-Case has recently improved its breather designs, featuring more desiccant and increased airflow without increasing the external dimensions of the breather, which adds up to 25-50% longer breather life. Now its VentGuard, Standard and HydroGuard breathers feature the new options, including: Domed cap to allow for better washdown … [Read more...]
