* - at max. stroke length and max. operating pressure for all material
versions
** - at constant conditions and min. 30 % stroke length
17.2.2 Self-Bleeding Liquid End
As the self-bleeding liquid end is used with outgassing media and when
operating with air bubbles, no dosing accuracy or reproducibility can be
provided.
The recommended minimum stroke length with self-bleeding dosing
pumps is 50 %.
