Filtration systems are used anywhere upgraded or auxiliary filtration is required in a hydraulic system. A filtration system is available in either permanent kidney loop circuits or portable filter cart assemblies. Either system is used to improve the cleanliness of the hydraulic fluid in a hydraulic machine. Often, filtration systems are used to augment existing […]

Where are hydraulic filters used?
Hydraulic filters are used anywhere in a hydraulic system particle contamination is to be removed. Particle contamination can be ingested through the reservoir, created during the manufacture of system components, or generated internally from the hydraulic components themselves (especially pumps and motors). Particle contamination is the primary cause of hydraulic component failure. Hydraulic filters are […]
Freudenberg Sealing Technologies research smart seals
Equipped with magnetic properties or electric conductivity, seals in the future will be expected to monitor their own wear, measure forces and perform other functions. Freudenberg Sealing Technologies is investigating smart materials that can take seals beyond their actual task of preventing material transfer. Seals are mostly made of elastomers, commonly known as rubber. In […]
Offline filtration ensures clean-running, efficient machines
Without a doubt, clean hydraulic fluid is the ultimate lifeblood of a hydraulic system. Contamination can reduce efficiency and possibly destroy machinery. That’s why many companies invest in offline filtration systems, commonly referred to as filter carts or kidney loop systems, for the external filtration of hydraulic fluids. Although traditionally used only when filtration was […]
Bauma and sustainability
While hydraulic and machine performance and value are front and center at Bauma, sustainability is a key theme as well. Since 1991 productivity in the construction machinery sector has been flat in terms of output per hour, signifying the need for more automation, labor saving and worker safety. That’s according to Juergen Weber, head of […]
Trelleborg Sealing Solutions appoints President of Marketing Americas
Trelleborg Sealing Solutions, a global developer, manufacturer and supplier of precision seals and bearings, appoints Linda Muroski, President of Marketing Americas, headquartered in Fort Wayne, Ind. Muroski joins Trelleborg Sealing Solutions from BASF where she held several leadership roles starting in 2000 and most recently served as the Director of Water Solutions, North America. With extensive […]
Eaton’s Extreme Duty Seal Guard extends motor life in harsh environments
Eaton announced that the Extreme Duty Seal Guard, an exclusion seal that offers the highest level of motor protection, is now available on the company’s full line of hydraulic Gerotor and Geroler motor products. The advanced seal helps protect equipment working in harsh conditions, such as cement augers, dredgers, fertilizer and salt spreaders, tillers and […]
A simple path to higher efficiency
Ken Korane • Contributing Editor Everyone is for energy efficiency—as long as it doesn’t cost too much. Replace an incandescent light with a new LED bulb? Check. Find out an LED costs five times that of the old one? Maybe not so fast. It’s no different with fluid-power systems. Engineers on a mission to improve […]
New hydraulic gear flow meters can take the pressure
Webtec, the hydraulic measurement and control company, based in Milwaukee, WI has announced the launch of a brand new range of high-pressure, precision gear flow meters rated up to 40 US gpm (150 lpm) for use on applications as diverse as hydraulic component leak testing, wind turbine lubrication monitoring and offshore diagnostic fault-finding. In an […]
What is viscosity index?
Viscosity index is a dimensionless number that represents how the viscosity of a hydraulic fluid changes with temperature. (It also applies to fluids like engine and automatic transmission oils, gear lubricants, and power-steering fluids.) The greater the viscosity index (VI), the smaller the change in fluid viscosity for a given change in temperature, and vice […]
