Abstract

A displacement pump includes a pump rod having a load concentrating feature extending from the head of the pump rod. The head of the pump rod is received within a slot of a drive link, and the drive link is configured to contact the load concentrating feature. Having the drive link contact the smaller diameter load concentrating feature reduces the misalignment between the driving force and the center of the pump rod and thereby reduces side-loading experienced by the pump rod. The displacement pump is configured to be used in a fluid dispensing system.
