摘要

The neck joint of a valve or pump comprises an elastomer mixture with carbon nanotubes (3%), and a basic mineral load. The neck joint is static and present between the pump/valve and a reservoir, and is dynamic, which is in contact with a movable element such as a piston rod of pump or shell pump of valve.
