Accuracies
- The reproducibility for the TZKa is better than  0.5 % in the stroke length range from 10 - 100 %
and better than  1 % for the TZHA (TZMa:  1 % at 30 % - 100 %) (with measurements
under constant conditions with water at 20 C – with correct installation, p > 1 bar)
- The dosing accuracy is approx  1 % at maximum stroke length and maximum back pressure.
Viscosity
The liquid ends are generally suitable for use up to a maximum viscosity of:
200 mPa s with valves without springs
500 mPa s with valves with valve springs
1000 mPa s with suitably designed installation
> 1000 mPa s with suitably designed installation and discussions with ProMinent
