Tab. 8: Operating conditions and limits
* Use of the dosing pump at ambient temperatures below 5°C must be checked individually. In those cases please contact the manufacturer.
** With a viscosity of ~300 mPa s and above, you must use spring-loaded valves.
*** If the viscosity is above 1000 mPa s, this must be checked individually
