charged persons or objects is hazardous to these components.

In the worst case scenario, they will be destroyed immediately or

will fail after start-up.

Observe the requirements in accordance with •

DIN EN 61340-5-1 / 5-2 to minimise or avoid the possibility of

damage caused by sudden electrostatic discharge!

Also ensure that you do not touch electronic components when •

the power supply voltage is present!

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)
