Abstract
A pump plunger is disclosed. The plunger may include a proximal end and a distal end opposite the proximal end. The plunger may also include a body portion extending between the proximal end and a second transition datum, and additionally include a transition section extending between a first transition datum and the second transition datum. The transition section may have a non-linear geometric profile. A first shoulder portion may be positioned adjacent to the transition section that may extend between the second transition datum and a third datum. The third datum may be positioned radially inward of the second transition datum. The plunger may also include a tip portion positioned adjacent to the first shoulder portion that may extend between the third datum and a fourth datum positioned at the distal end. The fourth datum may be positioned radially inward of the third datum.
