B1 Series gear pumps offer a wide variety of displacements for versatility and adaptability to a broad range of applications. B1 pumps are available in nine displacements, from .11 to .74 in3/rev (1,80 to 12,13 cm3/rev).
All B1 Series pumps have high-density gray iron construction with heat-treated alloy steel gears and shafts. Standard features include double lip seals, heavy-duty needle bearings and straight keyed shafts or tang shafts. Splined shafts, mechanical, high-pressure or fluoroelastomer seals, and relief and/or outlet check valves are available options.
