3 GENERAL INFORMATION
3.1 Unpacking and inspection
GD30P is a dispenser in the Flexicon Multi Filling System (FMFS). The GD30P cannot do
fillings by itself, but must be connected to Flexicon's control unit, MC12, or to a PC with
RS485 multidrop communication.
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 Flexicon A/S or your
supplier immediately.
When ordering spare parts or accessories for the GD30P, please state the serial number
stamped. The serial number is stamped on the label on the bottom of the GD30P.
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 - phase
ALWAYS REMEMBER that this machine must be earthed.
3.2 The Dispensing Principle
GD30P operates with a pump of positive displacement rotary type. The volume at the inlet
increases when the gears rotate and the product ids drawn into the pump. It is then
transported in the space between the gears and the periphery of the body to the discharge
side. The volume between the gears is reduced here and the product is forced out through
the outlet.
The gears operate without metallic contact with casing. The pumps have gears in AISI 316
acid resistant steel (PTFE impregnated). This gives an efficient performance and gentle
handling of liquids products.
The gaskets are made of EPDM.
THE PUMP MUST NOT RUN DRY.
The best performance is reached with a positive product support.
The pump needs a filling nozzle with cut off valve.
