摘要： A piston rod includes a piston end that is removably attached to the piston rod body. A sleeve extends around the piston rod body and interfaces with a seal disposed within a pump. A ring extends from the piston end defines at least a portion of a socket formed in the piston end for connecting the piston end and the piston rod body. The ring has a cylindrical ring exterior and the sleeve rests on the cylindrical ring exterior such that the shank, the ring, and the sleeve radially overlap each other.
