SystemDescription
sysTeM descripTiOn 5.
Due to the high reproducibility, the unit, which operates according to
the diaphragm pump principle, is especially suitable for the precise
dosing of very small fluid and gas quantities in the µl range.
The dosing unit can also be used for aggressive media because the
only media-wetted materials are PEEK and FFKM.
The symmetrical structure of the unit (2 x Type 6604, 1 x Type 6606,
PEEK connecting plate) allows bidirectional supply. The matching
electronic control system (RS232), including software, is available
as an option.
The supply rate of the dosing unit can be controlled via the mechanical
fine adjustment of the stroke and the frequency of the power supply
voltage. In addition to this, the supply rate depends on the viscosity of
the supplied medium as well as the flow resistances up and downstream
of the dosing unit (e.g. hose system)

Warning!
Burns, chemical burns through leaking medium.
Prior to the use of aggressive media, the resistance of the •
media-wetted parts must be checked.
