Item Information

Modern high-pressure hydraulic systems are demanding. Improved controls and long component life are expected. To deliver the high standards of performance, hydraulic components are built with tighter tolerance and higher system pressures, which increase the sensitivity of a system to contamination. Pressure filters are used to safeguard expensive downstream components from contaminants, helping to protect a system from devastating failure. Parker’s High-Pressure Inline Filter World Pressure Filter (WPF) series offers a new concept in High-Pressure Fluid Filtration Solutions. Parker engineers have developed an innovative alternative to conventional high pressure and reverse flow filters. The WPF design incorporates all the benefits of Ecoglass media along with a unique reverse flow and bypass valve arrangement. The design offers superior element integrity protection when transient reverse flow spikes are encountered. Parker pressure filters are a valuable and required component in meeting today’s system demands. Parker’s WPF series removes ingressed contamination before it flows downstream to sensitive components. They block pump generated debris before it gets to servo or proportional valves. There is no better high-pressure filter available today for durability and performance.
