Concentric AB-F15 PMP-USA-2011-6 2 DESCRIPTION, FEATURES AND BENEFITS Pictures on front cover are used with the kind permission of eg: Atlet, BT, Huddig, Scania, Toro and Volvo Construction Equipment Concentric F series gear pumps have an outstanding history in mobile o -highway applications. The F15 is the latest addition. Taking the best design components from the F20/F30 series and adding new technology, Concentric has created a product of very high e ciency, yet retains the robust nature of the traditional cast iron bodied gear pump. The gear and shaft are one piece construction for drive and driven gear providing superior resistance to fatigue and allowing the use of large diameter journals for higher load-bearing capacity. Made of high strength heat treated steel, the 14-tooth gears reduce pressure ripple (noise) and improve volumetric e - ciency. Large Te on impregnated bushings are installed in precision bored covers for optimum alignment, providing support area capable of handling most indirect drives and fan loads. This design uses one integrated balanced bronze pressure plate for the optimum in wear surface and strength. With an integrated “E” seal in the pressure plate, this design reduces clearance, o sets axial loading, and balances itself as pressure increases. The F15 series can be ported in a variety of SAE, DIN, NPT, BSPP, and JIS sizes and combinations of side or rear locations. Drive shafts in SAE splined, keyed, and taper are o ered. Mounting anges are SAE 2-bolt “A” or 2-bolt “B” with either single or double shaft seal con guration. The double seal option is designed for use when the pump pilot extends into a crankcase or transmission. It prevents uid from one environment entering the other.
