The dispense head is generally equipped
with:
•
Liquid line connection to inlet of fluid
pump line connection
• the tightening nut
• Standard connection to mating dip
tube
• the vent channel
The check valve ensures that there is no
flow back after transfer is complete and
there is no spill at disconnection. As soon
as the pump is activated, the check valve
opens. When the pump is switched off,
the negative pressure in the suction line is
reduced and the check valve closes.
To remove flammable or highly flammable
chemicals from a container, there is an
electrically conductive version of the dis-
pense head and the dip tube.
» The MOC of electrically conductive
plastic dispense heads and dip tubes
is always black in color due to the
carbon additive.
WARNING
Danger due to static charge.
Statically charged chemicals or dis-
pense heads, dip tubes, etc. can cause
sparks to arc creating an ignition
source.
• Ground the dip tube and dispense
head properly.
