IMPORTANT ASPECTS TO BE CONSIDERED DURING OPERATION
Check the output of the pump to ensure that the overflow
“
bypass
”
is only half full.
Inspect the pump to ensure that the operating pressure on the seal of the auger drive does not ex-
ceed 2 m water column.
Make certain that no pipelines are pressed together and no negative pressure arises in the supply
system.
The higher the DM content in the input material, the better the separation will be if the input medi-
um is homogenized. If the solid concentration of the input medium declines significantly, check the
solid cake by returning some of the separated solid to the separation process.
Under normal conditions, the arms of the output regulator
“
breathe
”
somewhat; in other words,
they move up and down a little. If the up and down movement of the arms is too large, you must
increase the contact pressure by increasing the leverage of the weights. If the contact pressure
becomes too high, the solid cake will become too hard [see section 14

ing

TAKING THE SEPARATOR OUT OF OPERATION
1. Switch off the feed pump to the separator.
2. Allow the separator to continue running for about 30-60 seconds until no more solid or separated slur-
ry is discharged, then switch it off.
Depending on the type of medium being separated, the separator may sit unused for up to a week or
more without the need to remove the solid cake.
3. For longer periods of disuse, the cake should be removed and the separator cleaned. To remove the
cake, open the lid and break up the cake by hand.
4. If the separator is also used in freezing temperatures, it should be ensured after operation that all
supply and return pipes as well as the separator itself are completely emptied in order to prevent
freezing of the slurry. If the cake is frozen solid in the separator, it must be thawed with hot water be-
fore restarting.
