Functional principle

The VISCOFLUX lite Ex drum emptying system consists of a FLUX eccentric worm-
drive pump with motor, a pump centring plate and a follower plate. At the start of the
pumping operation and during the pumping process the follower plate of the pump
lies on the surface of the material in the drum.
A vacuum is created during pumping with the eccentric worm-drive pump, whereby
the follower plate is pressed downwards. The flexible process seal seals the material
and at the same time ensures that there is almost no residue on the walls of the
drum.
To raise the follower plate, compressed air must be blown into the drum. The
compressed air presses the follower plate upwards.
The air pressure stops when the bottom bead on drums with roller beads is reached,
and the follower plate comes to a stop. In this position, the arresting hook will be
hooked to the edge of the drum. The pump is now pulled out of the system. The
follower plate tilts into the dismantling position. The pump centring plate is
dismantled. The follower plate is taken off with the handles.
