Tank Mounted Return Line Filter BGT Series

BGT Filters feature Parker’s exclusive Magnetic Pre-filtration core which collects ferromagnetic particles from fluid upstream of the filter element. This feature alone could save hundreds of dollars a year by protecting costly equipment from increased wear and malfunction by assuring that the fluid is as pure as possible when it leaves the filter. Even during bypass due to cold start up, ferrous contaminant is collected by the magnetic core, a feature of importance on any fluid power system.

Fluid flows through the inlet port into an enlarged area which reduces fluid velocity. Inlet flow does not impinge on the element. Filtration begins with magnetic pre-filtration of ferromagnetic particles in the full fluid flow upstream of the element, not downstream or in the reservoir. Built-in or system generated ferromagnetic wear debris (even particles smaller than the element rating) are collected by the high strength (3.0K Gauss) magnetic column. This results in extended element and oil life and reduced maintenance and downtime, which reduces overall operating cost.

Fluid passes through the element in an inside-to-outside direction, collecting particles inside the filter cartridge. This eliminates reinjection of contaminant during element change. Clean fluid then returns to the reservoir through the diffusor which prevents fluid aeration.

Normal return line filters, that flow outside-to-inside, allow contaminated fluid to drain back into the reservoir when the element is serviced. Simplified bypass design and location prevents flushing previously collected contaminant back into the system. Magnetic filtration occurs even during bypass. All potential leakage paths are o-ring sealed to eliminate bypass leakage that occurs in loose fitting valve assemblies.

BGT Filters are available with disposable elements of several contamination class levels for use in all common fluids. Optional accessories include visual and electric warning indicators that assure proper element service.
