Concentric F15 Ferra series gear pumps offer various design elements and updated technology to improve efficiency for the off-highway vehicle market. The gear and shaft are a one-piece construction to resist fatigue. Comprised of high-strength heat-treated steel, the 14-tooth gears reduce pressure ripple/noise and improve volumetric efficiency. Large diameter journals offer higher load-bearing capacity, and large Teflon-impregnated bushings are installed in precision-bored covers for optimum alignment, providing a support area capable of handling most indirect drives. An integrated balanced bronze pressure plate increases surface wear and strength. The F15 is available in various porting options, sizes, and combinations of side or rear locations. Displacement range is 19 to 50 cc (1.16 to 3.05 in3/rev) at speeds from 600 to 3600 rpm.
