An automotive company built an assembly plant on land that had a limestone base. Research found that if the limestone was removed, crushed and re-laid, the plant stability and harmonics would be improved to a point that would offset the cost of crushing the limestone.

Knowing the oxidation and water saturation levels of synthetic hydraulic fluids can help determine what fluid is best for your system.

By Chauntelle Baughman, CFPHS; Hydraquip Distribution Inc.

Knowing the oxidation and water saturation levels of synthetic hydraulic fluids can help you determine what fluid is best for your system. This article reviews different fluid classifications and highlights Panolin, a synthetic fluid that demonstrates superior performance in oxidation testing.

Hydraulic fluid filter

Tue, 06 Mar 2012 03:16:00 +0000

Oilmiser FILLorDRAIN hydraulic fluid filter system prevents airborne contamination between the drum and reservoir. Featuring a cast aluminum body, it is available in two designs. Tank-mounted version has a bottom flange with conventional filler/breather (6-hole, 2.88 in. bolt circle mounting pattern). Drum-mounted version has 2-in. NPT male pipe thread and mounts directly to the 2-in.

Leak detection kit

Mon, 13 Feb 2012 20:21:00 +0000

OPK-341 Industrial Leak Detection Kit pinpoints the source of fluid leaks in hydraulic equipment, compressors, gearboxes, and other industrial systems. Two 16 oz bottles of OIL-GLO 44 concentrated fluorescent oil dye will glow brightly when scanned with the OPTIMAX 3000 flashlight, to reveal the location of leaks. The OPTIMAX 3000 is a cordless, rechargeable, blue light LED inspection flashlight, which has a range of up to 20 ft (6.1 m). The kit includes an 8 oz spray bottle of GLO-AWAY dye cleaner, smart ac and dc chargers, and fluorescence-enhancing glasses.

Lubrication helps keep hydraulic components in balance

Mon, 13 Feb 2012 19:35:00 +0000

Understanding the linkage between hydrostatic balance and hydrodynamic lubrication is critical in maintaining long hydraulic component life.

Brendan Casey, HydraulicSupermarket.com

One of the keys to maximizing the service life of hydraulic components is to ensure that internal sliding parts are adequately lubricated to minimize friction and wear. Depending on the nature of the lubricated contacts, “adequate lubrication” ideally involves separation of the two sliding surfaces by a film of oil, known as full-film, or hydrodynamic lubrication. Forming and maintaining hydrodynamic lubrication depends on surface geometry, speed, load, and the viscosity of the lubricant.

Product release: Self-contained filter cart

Fri, 20 Jan 2012 19:45:00 +0000

Model BFC 553 filter cart allows cleaning and transferring of petroleum-based fluids at a work site. It is designed to remove contamination as fluids are transferred from a drum and “polish” fluids in existing system. Its dc motor operates from an on-board rechargeable power supply, so it does not require an external power source. It can also be plugged into a 115-V power supply.
