3 Setup / function
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 dispense 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 dispense heads, dip tubes, etc. can cause sparks
to arc creating an ignition source.
• Ground the dip tube and dispense head properly.
