Agrégat de pompes de dosage et procédé de commande d'un agrégat de pompes de dosage

摘要

The dosing pump unit has a dosing chamber (16), a displacer (14) adjoining chamber and displaced by a displacement drive (6) and a control device (26) for controlling the displacement drive. The control device is designed such that it controls the displacement drive for certain target delivery flows to be generated by the dosing pump such that a stroke of the displacer is started with increased stroke speed and is then continued with another lower stroke speed. An independent claim is also included for a method for controlling dosing pump unit.
