General information
4.1
Unpacking and inspection
PD22 is a peristaltic filler in the Flexicon Multi Filling System (FMFS). The PD22 cannot do
fillings by itself, but must be connected to Flexicons control unit, the MC12.
Please check that all ordered items have been received and that no items were damaged
during transport. In case of any defects or omissions, please contact WM Flexicon A/S or
your supplier immediately.
When ordering spare parts or accessories for the PD22, please state the serial number
stamped. The serial number is stamped on the label on the bottom of the PD22.
Please check that the connected mains plug is of the correct type with the correct earthed switch.
If this is not the case, the correct type of plug must be mounted with the following connections.
Yellow-green:
earth
Blue:

ALWAYS REMEMBER that this machine must be earthed.
4.2
The peristaltic principle
PD22 operates with a peristaltic dispenser head (tube pump), where the liquid only comes
into contact with the flexible tube, the tube connections and the filling needle. The tubes are
usually made of silicone, but other materials can also be used.
The dispenser head is designed in such a way that sterilized tubes can be mounted in the
head without affecting the sterility.
WM Flexicon
’s tubes fulfil biopharma requirements.
The tubes are delivered in sealed packages and are provided with a batch number which
makes it possible to trace the tubes all the way back to the raw material source.
For this reason the PD22 is especially suited for aseptic applications and for preventing
cross-contamination among different products.
The dispenser head is self-priming, and the dispenser head itself can stand to be run dry.
It is recommended not to let the dispenser head be run dry for a long period WITH
MOUNTED TUBES, since this will lead to particle release.
A peristaltic dispenser head is not suitable for viscous products.
