ClearSeal PRW, from Seal Engineering AS, is a patented, pressure-released, internal wiper with a filter function that prevents debris in the hydraulic oil /pressure media from reaching seals, bearings and other components. It provides insurance against breakdown in hydraulic systems due to contaminated media. ClearSeal’s compact design and … [Read more...]
Adsorber filters protect against harmful condensation
Water in the oil is a serious issue for many hydraulic systems, because it can lead to increased wear and leakage. Adsorber filters which prevent moisture ingress via the tank breather system provide a remedy, according to engineers at HANSA-FLEX, Bremen, Germany. Unfortunately, although these filters can prevent serious damage and high … [Read more...]
New oil dehydrator technology from Schroeder Industries
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...]
Early warning system heads off downtime
Unit Fluid Monitoring (UFM) systems permit in-depth monitoring of hydraulic power packs and lubrication systems, according to officials at Hainzl, a manufacturer of hydraulic, automation and robotic products based in Linz, Austria. The main focus is on analyzing the oil for signs of humidity, aging and degree of contamination, as well as monitoring … [Read more...]

Greene Tweed has announced the availability of its innovative Arlon 3000 XT thermoplastic for extreme conditions in oil and gas applications. Greene Tweed’s advanced engineering thermoplastic, Arlon 3000 XT, delivers improved performance over other available materials: in dynamic mechanical analysis, it demonstrated a glass transition … [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...]
Trelleborg’s tensioner cylinder seals exceed 20-year lifecycle rating
Seals used in offshore rig tensioner cylinders must meet the same rigorous lifecycles as the cylinders themselves. Because offshore environments are harsh and installation and maintenance can be difficult, tensioner cylinders must have a 20-year life. That was why, more than 20 years ago, Trelleborg Sealing Solutions conducted research, determining … [Read more...]
Particle monitor for real-time analysis
The redesigned Stauff LPM-II-plus particle monitor is an optical particle counter with high-performance LEDs that automatically detects the degree of contamination of hydraulic fluids and determines particle sizes in compliance with ISO 4406, NAS 1638, AS 4059E and ISO 11218 standards. It is for continuous measurement or analysis in … [Read more...]
