Technical Data

Dosing units series CVDModular assembled units for multiple dosing tasks.It can be chosen between two different basic designs (CVD1+CVD2).The dosing units will be equipped with sera-dosing pumps especiallytuned for the operating purpose.Available materials: pipework: PVC/PP; sealings: EPDM/FPM

*) please note the max. admissible counter pressure of the chosen dosing pump!
