2 PD22 I / PD22 P important notice
There are 2 versions of the PD22.
➢The PD22 I (individual)
➢The PD22 P (Panel mount)
They share the same functions and programming routines.
The main difference is that the PD22 I has its own cabinet, and the PD22 P is mounted
through a panel.
Besides this there are differences in the way the “I” and “P” version are connected to power
supply and to the external pump controller (MC12).
In the last sections of the manual we will describe the connections and interfaces.
For the remainder of this manual the PD22 will be designated as follows:
PD22: for general descriptions covering both versions.
PD22 I: for descriptions specific to the ”I” version.
PD22 P: for descriptions specific to the ”P” version.

4 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: neutral
Brown: line
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.

Fig. 4.3
Address "1" is the factory setting of PD22.
If the PD22 is one of several filling stations in a system, none of the stations may have the
same address and it must therefore be changed.
Change of address is performed via a dip-switch placed at the bottom of the PD22. This
change may only be carried out when the machine is turned off at the main power switch.
Addresses between 1 and 16 may be chosen, and Fig. 4.3 shows the various combinations.

5.1 Dispenser head
The dispenser head can work with different tube diameters.
The dispenser head works with two parallel tubes which are squeezed by six rollers mounted
on ball bearings. The rollers in the two sections are offset in order to eliminate pulsing.

6 Dispensing with PD22
For optimal dispensing with the PD22, the following should be observed:
6.1 Vessel Placement
In order to build up adequate pressure and reduce friction, it is recommendable to place the
vessel containing fill media at the same level as pump head or preferably above the pump
head level. Placing the vessel higher than pump head level provides positive product support
and may reduce the calibration interval. It is also recommended to place the vessel as close
as possible to the pump on suction side.

6.2 Tube size
Tubes must be selected according to the application and volume to be filled.
PD22 can operate with different tube dimensions chosen according to the volume to be
dispensed.
The tubes are designated by their internal diameters (i.d.) in millimetres. This value is always
used as designation for the individual tube, and this is also the value to be entered in function
2 at the MC12 master controller.
PD22 can operate with the filling nozzles, tubing and Y-connectors listed in the table below.
In order to obtain stable and good filling accuracy, the choice of tubing may be made
according to the following guidelines:

Fig. 6.2
Above mentioned tubes are silicone tubes and supplied by Watson-Marlow Flexicon A/S.
These can be sterilised by autoclaving, gamma radiation or ethylene oxide.
It is recommendable that the tubes are of such length that can allow placing the vessel close
to the pump head.
The tube ends must always be kept below the liquid level of the suction vessel in order to
keep the tubes from sucking air.
Avoid having tubes close to the bottom of product vessel.

6.3 Nature of fill media
The peristaltic dispensers are not suitable for viscous products. For viscous product another
type of dispenser from WM Flexicon can be used. In the case that the PD22 should be used
and the product is of viscous nature, then heating the product before dispensing with PD22 is
recommended.
Another consideration is the surface tension of liquid. Product with high surface tension tends
to produce drip. Due to this fact it is difficult to have sufficient cut off after every individual
dispense. When filling with small volumes and high surface tension present drips are often
produced and constitute inaccuracy.
6.4 Priming tubes
In order to evacuate air from the tubes and prepare the tubes for filling, it is necessary to
prime the tubes. Priming must be done adequately and continued until the tube material
hysteresis disappears as well as any air bubbles.
6.5 Drip
When dispensing very small volumes, the last drop of the filling constitutes a big part of the
total filling.
For small volumes a dumping nozzle system can be applied to control the last drop of filling.
When dispensing with very large volumes, the shape of nozzle and the filling speed required
may not always be compatible.
For this reason consideration should be done if using non-return valve or forced back-suction
is necessary.
Flexicon dispensers offer back-suction (reversing) after every individual dispensing.
6.6 Hard Feed
When dispensing with small tubes, counter pressure on the pressure side of pump head
might constitute inaccuracy and instability in filling (hard feed). In some cases the problem
can be resolved by using a larger tube on the pressure side (after Y-connector).

7 Tube assembly
7.1 Assembly of Y-connectors
Since the dispenser head of PD22 is fitted with a double rotor, two suction tubes are used all
the way through the dispenser head. These two suction tubes are joined by a Y-connector
just behind the dispenser head.
Fig. 7.1
The chosen tube is joined by a Y-connector as shown in Fig. 7.1.
7.2 Placing tubes in the pump head
After selecting a suitable tube diameter and after fitting the tubes with Y- connector and filling
needle, mount the tubes in the dispenser head.
Fig. 7.2
Open the dispenser head by turning the two locking pins (1) over the tube bridge (2), after
which the tube bridge can be lifted up.
It will now be possible to remove the tube lock (3) from its dowel pin.

Fig. 7.3
Mount the correct tube lock (1) on its dowel pin and place the tubes (2) in the dispenser
head. The Y-connector must be situated to the right of the dispenser head.
It is important that the tubes are situated in the two notches (3).
Now place the tube bridge in its tracks and engage the two locking pins.
Fig. 7.4
The tube ends must always be kept below the liquid level of the suction vessel in order to
keep the tubes from sucking air.
NB! Never leave the dispenser mounted with tubes overnight.
At least tip the locking pins up in order not to retain the tube in pressure.

8 Programming
8.1 Programming principle
In the following, a parameter will be the value of a single function, i.e. volume, tube diameter
or velocity. A program will be a complete set of parameters which together will constitute the
PD22 work instructions.
The actual programming will be made on the MC12 and reference is made to the MC12
manual.
8.2 PD22 parameters
1. Volume
Value: ml
Range: 10 - 9999 ml
PD22 can dispense from 10 to 9999 ml, but for volumes exceeding approx. 1000 ml, the
capacity will drop significantly.
If the volume is changed, a recalibration should be made.
2. Tubes
Value: Inside diameter (i.d.) in mm
Range: 3.0 - 5.0 - 6.5 - 8.5 - 10.0 - 12.5
If the tube is changed, a new calibration must always be made.
3. Velocity
Value: Revolutions per minute (rpm)
Range: 30 - 250 rpm
If the velocity is changed, a recalibration should be made.
4. Acceleration/deceleration
Value: An integral number
Range: 1 - 100
The acceleration and the deceleration will always be the same. The lowest value (1) will give
the slowest acceleration, and the highest value (100) will give the fastest acceleration.
If the acceleration is changed, a recalibration should be made.
5. Reversing (back suction)
Value: An integral number
Range: 0 - 10
If the rotor is moved a little backwards (reversing) after the completion of fillings, a minor
back suction will be created. This can prevent dripping from the filling needle.
The value "0" will give no reversing, but the value "10" will give maximum reversing.
ALWAYS make a recalibration if the reversing value is altered.
For other programming possibilities, reference is made to the MC12 manual.

9 Cleaning and maintenance
9.1 Daily cleaning
As PD22 is not in direct contact with the dispensed product, daily cleaning will not be
necessary except for the normal routine cleaning of production equipment.
Liquids must NOT be splashed onto the PD22.
It may only be cleaned with a damp paper towel or a firmly wrung cloth.
The cabinet is made of stainless steel and anodized aluminium, and normal cleaning agents
such as tepid/medium hot water, ethyl alcohol (ethanol) 70% may be used all over the
machine.
9.2 Sterilization
If PD22 is placed in an aseptic environment, the sterilization may be made as described in
section 9.1, or you may sterilize PD22 by gases observing the following precautions.
If you use gases that might injure and corrode contacts and other metals, air slots and
sockets MUST be covered with tape.
9.3 Maintenance
As all movable parts in PD22 are maintenance-free, no maintenance is required apart from
normal cleaning of the equipment.
Should service be needed, please contact WM Flexicon A/S or your supplier.
