4.4 Reproducibility
Reproducible
metering accuracy –5 % to +10 % at max. stroke length and max. back pressure for versions in all materials.
Reproducibility ±2 % under constant conditions and at minimum 30 % stroke length.
As the self-bleeding pump is used with outgassing media and in application with gas-bubbles,
the metering accuracy and reproducibility cannot be indicated.
The recommended min. stroke length for selfbleeding dosing pumps is 50 %.
4.5 Viscosity
The metering pumps are intended for use with liquids with a viscosity of up to:
• max. 200 mPas for standard liquid end
• max. 500 mPas for spring valves
• max. 50 mPas for self-degassing metering pumps.
