Abstract (en)
[origin: DE19849804A1] The invention relates to a line of products for gear pumps having different delivery volumes and which comprise at least two gear pumps (1, 100). Each gear pump comprises at least two displacement elements (45, 104, 105) which intermesh with each other, a first displacement element (4, 104) and a second displacement element (5, 105) which are shaped as gearwheels. The individual gear pumps of the line of products are provided with a) essentially identical measurements for the axle base (a) between the theoretical axles and/or the theoretical rotational axles of said two displacement elements and b) an essentially identical toothing (zb1, zb2) in the form of an essentially identical axial range of the toothing elements. The individual toothing elements differ from each other in at least the size of the core circle diameter (dk1, dk2, dk1b, dk2b) of at least one of said displacement elements.
