The Parker GMF Series is a highly compact, environmentally friendly inline hydraulic oil filter that features a re-usable element core. Capable of flows up to 600 L/min (158 GPM). Maximum allowable operating pressure 70 bar (1,015 psi).
The Parker GMF Series is a medium pressure, inline hydraulic oil filter that provides high-efficiency filtration for equipment in demanding environments, including mining, construction, marine, drilling, and agricultural applications. The filter’s highly compact design can save over 500 mm of space envelope when compared to traditional inline hydraulic filters. It also features a reusable element core with patented filtration technology, which reduces waste by up to 50% when compared to conventional filters with non-reusable cores.
GMF Series filters serve as a highly economical filtration solution in medium pressure range applications (up to 70 bar), where compact envelopes and excellent fatigue pressure ratings are of the utmost importance. Specific examples include (but are not limited to) offline filter loops, machine tools, oil patch drilling equipment, injection molding machines, hydrostatic drive charge pumps, and pilot lines for servo controls.
Prior to the availability of the GMF Series inline filter, applications such as these were restricted by limitations of a spin-on can or forced into the higher-cost range of high pressure filters. The GMF Series fills this gap and is available with various port connection types, filtration media (2,5,10, and 20 micron), and flow capacities (up to 600 L/min) to meet the unique requirements of customers’ hydraulic circuits.
Standard available port connection range:
• G16 up to G32
