Dosing pump

摘要

The dosing pump has a drive unit and a membrane pump (10) that is driven by the drive unit via a piston rod. The drive unit has a drive motor (26) for driving a piston drive (16) for moving the piston rod, whereby a planetary gear mechanism (28) is arranged between the drive motor and the piston drive. The piston drive has an eccentric element (18) for converting rotary motion of the motor and gear mechanism to linear rod motion.
