Operating Manual for
FAN Press Screw Separator PSS 1.1-300
S
The separator must be set up so that the solid can be freely
discharged. There must be a corresponding height difference
between the solid discharge point and the ground. The volume
of the cone of discharged material can be determined based on
the setup height.
The overflow line for the raw slurry as well as the drainage line
of the separated slurry should drain without pressure into the
corresponding storage tanks.
The overflow line should be run without a
“
siphon
”
in order to
avoid a lifting effect and to ensure good separator throughput
(see also section 14
“
Problems - Troubleshooting
”
.
Avoid winding, dipping and twisting of the pipeline and use tub-
ing that is resistant to negative pressure.
4.8.1 Inflow Setup
The inflow element is mounted vertically on the inflow flange
(top of separator housing).
Connect the supply line to the lower horizontal connection
(socket DN75) of the inflow element. A tube of DN75 is re-
quired for this.
Connect the overflow line to the upper horizontal connection
(socket DN75) of the inflow element. A tube of DN75 is also
required for this.
On the vertical connection of the overflow line (socket 1
½”). must be connected the ventilation tube This prevents the
buildup of negative pressure in the separator if the medium
creates suction in the return line (siphon effect).
The ventilation tube should project at least 1,5 m above the
overflow.
4.8.2 Drainage Line
The drainage line is connected to outlet tube DN89 on the
bottom of separator housing. A tube of DN90 is required for
this.
NOTE
If no FAN/BAUER pump is installed, the pump for supplying the separator should have a
pump rate of at least 15 m³/h since the capacity of the separator otherwise cannot be fully
utilized. To keep pressure losses due to pipe friction low, the pipes should have a diameter
of at least 75 mm.
