3 General information
3.1 Unpacking and inspection
PD12 is a peristaltic filler in the Flexicon Multi Filling System (FMFS). The PD12 can not 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 PD12, please state the serial number
stamped. The serial number is stamped on the label on the bottom of the PD12.
ALWAYS REMEMBER that this machine must be earthed.
3.2 The peristaltic principle
PD12 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 Flexicons tubes fullfills 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 PD12 is specially 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.
