Schroeder Industries has introduced the Schroeder 30-gpm North American Vacuum Dehydrator (NAV) Unit. With the price of oil fluctuating, the increased cost of used oil disposal, and the pressure to maintain a 100% planned up-time schedule, the only effective solution is to maintain the fluid at the highest purity levels, and by doing so, extend … [Read more...]
How should you store your elastomer seals for hydraulic and pneumatic use?
Elastomer seals are built to handle a wide range of demanding hydraulic and pneumatic applications. A seal’s design and its material properties are two keys to lasting performance, but experts also offer some important recommendations on proper safekeeping if seals will be stored for a period of time prior to installation. Elastomer … [Read more...]
How do you remove water from your hydraulic system?
It’s common knowledge that particulate contamination is unwanted in hydraulic systems. Contamination in hydraulic oil can damage mobile and industrial machinery. Of as much concern should be water in oil, as it too can lead to component failure. Water in hydraulic fluid can be seen as free, dissolved or emulsified and can reduce hydraulic … [Read more...]
2-in-1 suction return filter for cold start applications
In tractors with a mixed response common oil circuit for transmission and power hydraulics, a suction filter is usually used to protect the pump and a return filter to ensure oil cleanliness. To protect the system during cold start, a coarse safety screen is often also installed in the suction line, but this a disadvantage of this design is that … [Read more...]
When are static seals used in hydraulics?
By Josh Cosford, Contributing Editor Static seals are used in hydraulic applications where two mating surfaces or edges require positive sealing. A static seal, by definition, is one that remains stationary and subjected to no movement and its related friction. A static seal may be exposed to hydraulic pressure on both sides or be exposed to … [Read more...]
New Material Research Center from Donaldson to focus on filter media
Donaldson Company Inc. broke ground on a $15 million Material Research Center at its corporate headquarters in Bloomington, Minn. At the groundbreaking ceremony, Michael Wynblatt, vice president and chief technology officer, said, “The secret to leading in the filtration market is having great filter media, and that's enabled by having great … [Read more...]
Return-line filters for tank optimization
Thanks to strong R&D activities in the field of tank optimization and, in particular, degassing of hydraulic fluids, engineers at Hydac have developed a new filter line. The products include a refined housing design and flow based on an in-to-out concept. In-to-out filtration helps ensure low outlet velocity and minimizes turbulence in the tank. … [Read more...]
New filters protect sensitive electrohydraulics
Atos, with headquarters in Sesto Calende, Italy, has introduced a new line of hydraulic filters. It rounds out the company's product portfolio that includes proportional, on-off and safety valves, cylinders and servocylinders, pumps, manifolds and systems. The filters ensure circuits maintain recommended fluid cleanliness levels in hydraulic … [Read more...]
Argo-Hytos announces new filter series
Argo-Hytos, Kraichtal, Germany, has announced a new filter-element series that reportedly offers significant performance improvements over the company’s current Exapor Max 2 elements. The new-generation series, called Exapor Max 3, will be officially introduced at the Hannover Fair in April. According to company engineers, development of the … [Read more...]
How do you decontaminate a hydraulic system after contamination is found?
After contamination is found in your hydraulic system, how are you supposed to decontaminate it? The simple answer is time and money. Once a system gets contaminated, it gets costly. When a system goes down, costs skyrocket. On one system, production time was worth $2,400 a minute when it was down — and it was down for 32 hours. That was enough … [Read more...]
