Filtration of oil lubricated equipment is not a new concept. Automotive filters have been around since the 1920’s and by the mid 1940’s, pleated filters were being used on hydraulic equipment. However, a comparatively recent idea is to use filters to target clearance sized particles to promote a higher level of component reliability. Oil filters…
STAUFF offers filter elements for the interchange market
In addition to its own comprehensive line of hydraulic filters, STAUFF also offers a complete range of replacement elements for most makes and models of filters worldwide. More than 10,000 different STAUFF elements are available online for the interchange market. Users can also get STAUFF quality and reliability even if they do not have STAUFF filters. While designed…
Trends in filters and lubricants
By one estimate, 80% of all breakdowns in lubricated machines are related to pollutants in the oil. Even in small amounts, contaminants can increase operating costs associated with maintenance, downtime, or equipment replacements. Enough particles measuring only 1-μm in size (invisible to the human eye) can knock out a 20-ton gearbox. The solution: rigorous particle…
60 months between gear oil changes? Yes, says recent filter
Oil quality is a decisive factor for the service life of a gearbox. In addition to the type of lubricants used, (e.g. synthetic oil with improved lubricating properties to extend service life) a recent upgrade increases potential to optimize oil quality and extend service life. Gearbox wear is determined by operating conditions and stresses exerted…
Powder composites make low-loss chokes and filters
A line of inductive components feature low-loss, good EMC characteristics, and a space-saving design. Their cores consist of powder composites, which developer SMP (Sintermetalle Prometheus GmbH & Co.) engineers for each application. And depending on application, components are constructed either as single-conductor chokes for high-current applications, individual chokes, choke modules, or LC filters. The devices…
Filters for wind-turbine hydraulics
Eaton’s Vickers Filters handle flows to 450 gpm and pressures to 6,090 psi. Bypass valves, pressure drop indicators, and media grades facilitate filter installation and provide needed system cleanliness. A closer look at reservoir vent filters shows its useful features. These sport visual indicators and corrosion-resistant housings. In addition to particle control, these filters also…
