Special Features of the Separator
Fine Tuner
The Fine Tuner, which has been deve-
lopedbyGEAWestfaliaSeparatorGroup,
is a combination between a centripetal
pumpandaparingtube.Itischaracterised
by a substantially improved efficiency
factor compared to conventional centri-
petalpumps.Thisistheratioofthecon-
versionofrotationalenergyintopressure.

Hydrohermetic vapour seal
Thehydrohermetic vapour seal (sealing
by liquid)preventsvapours fromrising

centripetal pump chamber. This has a
positveeffectincaseofhigherseparating
temperatures(>90°).

Available Drives for Edible Oil Separators
Gear drive
The conventional drive concept of the
separatorsisthewormwheelgear,fluid
clutch and standard motor with direct
switching.Thetoothingofthewormwheel
gearwasoptimisedinordertoreducethe
noiselevel.
Flat belt drive
Flatbeltdrivecanbeusedfortheheavy
bowls of larger machines. The power
transmissionfromthetorque-controlled
motortothebowlspindleisviaasingleflat
beltwithoutanintermediaryclutch.The
design isvery simpleandmaintenance-
friendly. The spindle can be removed
together with the complete bearing
assemblyandcanbeservicedoutsidethe
machine.This reduces considerably the
downtimeformaintenance.
Direct drive
Directdriveistheintelligentsimplification
in separation technology. Direct drive
isused inapplicationswhere theupper
limitforgear loadshasbeenreachedor
when belt drive is undesirable. Direct
driveseparatorsdrivewithvirtuallyloss-
free power transmission. Less energy
consumption, lower maintenance and
space mean increased performance for
production.
