17.2 Accuracy
17.2.1
Standard Liquid End
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 reproducibility can be
provided.
The recommended minimum stroke length with self-bleeding dosing
pumps is 50 %.
17.3
Viscosity
The liquid ends are suitable for the following viscosity ranges:
Design Range Unit
Standard 0 ... 200 mPas
With valve springs 200 ... 500 mPas
With HV head 500 ... 3000* mPas
Self-bleeding (SEK) 0 ... 50 mPas
* Even significantly higher with corrected adjusted installation. Contact
