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 […]
Hydraulic Fluids
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 […]
Why is viscosity important in hydraulic fluids?
Viscosity, according to Webster’s Dictionary, is the property of fluids and semi-fluids that defines its internal resistance to flow and shear. Or, in more simple terms, how thick or thin a fluid is. For example, water is less viscous than tar. (Fluids that have no resistance to shear stress are known as ideal fluids or […]
High viscosity mobile filtration systems from Schroeder Industries
Schroeder Industries released the MFD-MV High Viscosity Mobile Filtration Systems. The MFD-MV cart is capable of handling fluids of up to 5,000 SUS, at 6 or 10 gpm, bridging the gap between the regular carts and the MFD-HV high viscosity cart for fluids up to 10,000 SUS The MFD-MV is a compact, self-contained filtration system […]
How hydraulic fluids affect energy efficiency
The fluid is a key part of any hydraulic system. It transmits power, lubricates components, transfers heat, acts as a sealing agent, and helps minimize the harmful effects of contamination like dirt and water. And hydraulic fluid has become increasingly important when it comes to overall system efficiency. That’s because OEMs and equipment users are […]
