Abstract
A precision volumetric pump with a bellows hermetic seal provides compliance time performance comparable to a conventional pump having a dynamic seal. However, the precision volumetric pump with a bellows hermetic seal is enabled to operate over a very long service life with minimal or no maintenance without a propensity to develop leaks over the long service life.
