Improving the cleanliness of hydraulics

Pall Corporation has introduced a new series of filters, dubbed the Ultipleat SRT, that combine a compact element design with new filtration media that improves fluid cleanliness to increase the reliability and longevity of hydraulic systems.

Contamination of hydraulic system fluids reduces the reliability and longevity of industrial and mobile equipment. It often results in unplanned for and costly downtime as manufacturing processes have to be stopped to repair or replace system components.

Filters are used to prevent contamination of the fluid, but traditional ‘fan’ pleated hydraulic filters typically have a non-uniform flow distribution that can result in uneven dirt capture and pleat collapse in the element which can shorten the useful life of the filter.

To address this problem, Pall Corporation has now introduced a new series of filters, dubbed the Ultipleat SRT, that combine a compact element design with new filtration media that improves fluid cleanliness to increase the reliability and longevity of hydraulic systems.

The Ultipleat SRT filter’s curved pleats are designed to create an even flow path for uniform collection of contaminants including metal, dust particles and debris caused by the wear of components.

Curved pleats also enable maximum use of the entire filter medium by leaving no unused space, which extends filter service life.

For its part, the new stress-resistant media mitigate filter problems created by normal operating system stresses, such as variable flow and pressure, which can result in the release of particulate contaminants into the hydraulic fluid.

The media’s proprietary anti-static construction also reduces electrostatic charges that can be generated by the flow of hydraulic fluids thus preventing damage to the filter and improving operation safety.

The company says that the combination of design and filtration media significantly improves the cleanliness of fluids to protect hydraulic system equipment and components.
