Table 9: Operating conditions and limits
* 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 is above 1000 mPa∙s, this must be checked individually and the stroke frequency must be between 50 and 100 strokes/min.
