* Use of the dosing pump at ambient temperatures below 41 °F must be checked individually. In such cases, please contact the manufacturer.
** With a viscosity of ~300 mPa∙s and above, you must use spring-loaded valves.
*** If the viscosity of the medium is larger than 1000 mPa·s, the use of the dosing pump must be checked individually. In such cases, please contact the
manufacturer.
