* The stated performance data represents minimum values calculated using water as the medium at 20 °C.
** Suction lift with a filled suction line and filled liquid end.
*** Priming lifts with clean and moist valves. Priming lift at
100% stroke length and free drainage or opened
vent valve.

Data Value Unit
Capacity range of the series -5 ... +10 % *
Reproducibility ±2 % **
* - 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 reproduci‐
bility can be provided.
The recommended minimum stroke length with self-bleeding
dosing pumps is 50 %.
