2.3 Flexicon pumps used in multi-filling system, short description.
The Watson Marlow Flexicon multi filling system consists of up to 16 filling dispensers (pumps)
connected via a fieldbus to a MC controller.
The dispensers can be peristaltic dispenser pumps (PD12 and PD22) and gear dispenser pumps
(GD30).
The MC controller can be either a MC12 controller with integrated keyboard and display to enter data
and control the dispensing or MC100 for integration in control systems.
This manual describes the MC100 controller.
The pumps are used for dispensing accurate doses of liquid into vials.
For this purpose there are a number of parameters, which are used to control the pump:
Speed: The range for the dispensing speed is 30 to 600 rpm depending on the
pump and the tube selected
Acceleration:
The range is 1 to 200 rpm/s depending on the pump and the tube selected.
Reverse (back sucking): Is a figure between 1 and 10 defining a short reverse pumping to prevent
dripping after the dispensing.
Tube:
The pumps hold a tube table of up to 10 tubes, which can be read from the
pumps. The tubes are depending on the pump type. Thus the pump table
can be down loaded from the pump software via the MC100.
Volume:
The volume the pump has to dispense at each filling. Please also see serial
and parallel mode below.
Density:
The density [g/cm 3 ] for the product to be filled. Used when calculating the
calibration value.
Calibration:
The net weight filled during dispensing. When a new volume is defined for a
pump it will dispense approximately 70 – 80% of this volume until
calibrated.
The calibration is normally done by tare weighing a vial, filling it and
weighing it again to calculate the net filling weight. The net weight filled is
sent to the MC100. The MC 100 then calculates the dispensing data and
sends it to the pump in question.
Please see the manual for the pump for further details.
When more than 1 pump is connected to the MC100, it is possible to operate the filling system (MC
100 with pumps) in 3 different operating modes: Individual, parallel and serial mode.
Individual mode: All the different types of WM-Flexicon pumps can be connected and run
independently for all parameters.
Parallel mode: This mode requires that all enabled pump are of the same type, i.e. all
PD12; all PD22 or all GD30.
Different pump types can be connected to the MC 100, but only pumps of
the same type can be enabled and operated together in parallel mode.
In parallel mode a virtual pump (pump no. 0) is be used to hold common
parameters for all the enabled pumps. However, the pumps will still have
to be calibrated individually.
