1 Introduction
This manual covers two models.
PD12 IHS (high speed).
This model fills one bottle at a time.
In the double head the tubes are mounted in pairs of 2 and via y-connectors these are joined into one
tube in order to fill one bottle at a time.
and
PD12 IDH (double head).
This model fills two bottles simultaneously.
In the double head the tubes are mounted in pairs of 2 and via y-connectors each set of tubes are
joined into one tube in order to fill two bottles simultaneously.
In general all sections of the manual cover both models; unless clearly specified.
1.1 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 nozzle. 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.
The dispenser head is self-priming, and the dispenser head itself can stand to be run dry (not
recommended for the sake of the tubes).
The dispenser head on PD12 works with four parallel tubes which are squeezed by rollers mounted
on ball bearings. The rollers in are offset in order to eliminate pulsation.
