A new and improved gear pump assembly, and a new and improved hot melt adhesive applicator assembly having a plurality of the new and improved gear pump assemblies incorporated therein, wherein each gear pump assembly is mounted upon the applicator assembly in an entirely independent manner such that each gear pump assembly can be individually removed from the applicator assembly, and replaced back onto the applicator assembly, as may be necessary in connection with, for example, repair or maintenance procedures. The independence of each gear pump assembly also effectively prevents damage to one gear pump assembly from adversely affecting the operation of the other gear pump assemblies. Furthermore, in view of the fact that a driven gear of each gear pump assembly projects radially outwardly through an end face of the gear pump assembly so as to operatively engage a common drive shaft of the applicator assembly, as opposed to having the common drive shaft of the applicator assembly pass through side portions or faces of all of the gear pump assemblies, not only is the aforenoted independent mounting of the plurality of gear pump assemblies upon the applicator assembly facilitated, but in addition, the need for all dynamic shaft seals, normally necessarily provided between the common drive shaft and one of the gear members of each gear pump assembly, is eliminated.
