1.1 Correct usage

Centrifugal separators – called separators in short – are used
• for the separation of liquid mixtures which consist of two liquids, with simulta-
neous removal of the solids contained in the liquids.
• for removing (clarifying) solids from a liquid.
The separator is designed

• for a very high bowl speed.
The admissible bowl speed depends on the chemical and physical properties
of the product:
– Temperature
– Density of the fluid and solid components.
• for products which contain no corrosive and erosive components.
The aggressiveness of the product influences the careful selection of the bowl
material.
Only products conforming to the specifications on the nameplate may be pro-
cessed.
• in accordance with the method of application of the separator agreed with
GEA Westfalia Separator. Refer to the data sheet and contractually agree-
ments.
• in accordance with the admissible utilities (cleaning agents, lubricants, operat-
ing liquids etc.) specified in the documentation or on the data sheet.
Intended use involves

• paying attention to the safety precautions, the instruction manual of the sepa-
rator and the safety markings on the separator.
• adhering to the data on the nameplate, e.g. maximum admissible bowl speed.
Further information on the intended use of the separator such as
– agreed areas,
– density of the product
– throughput capacities
– temperatures
– pressures etc.
is given in the documentation or the data sheet furnished with the documenta-
tion.
The contractually agreed conditions agreed with GEA Westfalia Separator on
the intended use of the separator must be passed on to the operating personnel
by the plant operator.
Any operating mode deviating from this is not intended use and can result
in severe damage to property and persons!

2060-9001-325 / 0414 11
1.2 Non-compliance with the intended use

Any use that deviates from the intended use is considered to be non-
compliant.
The separator may not be operated by:

• Persons who have not read and understood these basic safety precautions.
• Persons who have not read and understood the instruction manual of the
separator.
• Persons who have not been briefed on proper and correct operation.
• Persons who have not been adequately trained.
• Persons who have not reached the minimum age of 18 years.
The separator may not be operated

• when the product fed does not conform to the specifications on the name-
plate.
– Product with excessively high density
– Solids with excessively high density
– Product with excessively high temperature
• when the max. admissible bowl speed has been exceeded through electrical
or electronic manipulation of the drive.
• in an incomplete state of assembly, e.g.
– required supervisory equipment is not activated or has been switched off.
– the required safety and/or protective covers have not been installed.
• by persons who are not adequately trained.
• when the separator is operated with spare parts which do not come from GEA
Westfalia Separator.
Non-compliance with intended use can result in severe damage to proper-

ty and persons!

12 2060-9001-325 / 0414
1.3 Safety markings

The safety markings (adhesive and metal plates) are attached to all separators
on the hood and frame of the respective separator in such a way that they are
clearly visible.
All safety markings on the separator, control system and plant components must
always be in perfect condition.
• Clean dirty safety markings.
• Replace damaged safety markings.

Potential equalisation (protec-

tive-earth terminal)
The grounding protection is a measure
which, in the case of a malfunction,
leads off the touch voltage into the
earth.
Fig. 12
1.4 Operating principles

Centrifuges are used for the separation of liquid mixtures or for the separation of
solids out of liquids or liquid mixtures.
High centrifugal forces are produced in

the rotating bowl.
Fig. 13
Under the influence of the centrifugal forces, separation of the liquid mixture
and/or ejection of the solids particles takes place most rapidly.
The specifically heavier components are displaced to the bowl periphery,
whereas the specifically lighter components are displaced towards the centre of
the bowl.
The high centrifugal force is produced by very high bowl speeds. On the one
hand, high bowl speeds signify high efficiency, while on the other hand, they
signify high material stressing of the centrifuge.

1.6.4 Voltage cutoff during operation

When the voltage is cut off for longer than one second during operation, the
control system switches off automatically and the separating process is aborted.
Important:
– The bowl is not emptied. Product and solids remain in the bowl.
– The separator motor and product feed pump will be switched off.
– The control system switches itself back on automatically when the power
returns.
After the power returns

• Switch on the separator motor and product feed pump.

1.6.5 Maintenance and repair

Unfavourable operating conditions may require shorter maintenance intervals.
The factors listed below are unfavourable because they either attack the sepa-
rator material directly or impair the lubrication/cooling system:
• Aggressive product (chemical or physical)
• High product temperature
• Product with grease-decaying properties
• Environment: Temperature, dust, vapours
Particularly high-stressed separator

parts like
– Bowl lock ring,
– bowl bottom,
– bowl top and
– other bowl parts with a large outer
diameter
must be checked regularly to assure
safe and efficient operation.
Fig. 46
Timely maintenance of the separator and replacement of worn or damaged ma-

chine parts is essential for safe operation of the machine.
Use only genuine spare parts from Westfalia Separator. Otherwise, safety
risks may arise (see section 1.5.2).
Carry out the required cleaning thoroughly.

One-sided solid deposits in the bowl cause severe unbalance!
Maintenance and repair work may only be carried out to the extent described in
this instruction manual.
Maintenance and repair work not described in this manual may only be
carried out by the manufacturer or by "repair shops" authorized by the
manufacturer.
We, therefore, recommend in your own interest to have your separator inspect-
ed by our service engineers at regular intervals. These checks help to maintain
the operating safety and avoid unexpected downtime.

30 2060-9001-325 / 0414
Before carrying out work on the

separator and electrical plant com-
ponents:
• Make sure the separator is at a
standstill.
• Switch off all electrical appliances
via the main switch.
• Lock the installation to prevent it
from being accidentally switched on.
Fig. 47
• Do not loosen any part and do not

carry out maintenance or repair
work on the separator before the
separator is at a standstill.
The standstill check is described in
the section “bowl”.

Make sure that
– all moving parts are correctly aligned and not seized.
– that no parts are broken and that there is otherwise no damage which could
affect the operation of the tool.
• Have damaged tools repaired by specialists before using them again.
– Use only genuine spare parts from Westfalia Separator. Otherwise, the
safety of the tool can be impaired.
• Keep the tools clean and keep them in a dry, safe place.
Properly maintained and cleaned tools work more precisely and can be
checked better.

32 2060-9001-325 / 0414
• Collect dripping oil to prevent danger

of slipping or product infection.
• When handling waste oils note:
– They can be injurious to health,
depending on their chemical com-
position.
– Waste oil must be disposed of in
accordance with local regulations.
Fig. 53

2060-9001-325 / 0414 33
1.7 Explosion protection
• Strictly adhere to the prevailing local

rules and regulations for operating in
potentially explosive areas.
An area is "potentially explosive"
when there is (or must be expected)
an explosive atmosphere in such a
volume that specific preventive
measures concerning design, con-
struction, and the use of centrifuges
are required.
Fig. 54
• The operation of centrifuges in "zone 0" areas, i.e. where a dangerous

explosive atmosphere is prevailing continuously or for long periods or
frequently, is not permitted!
• Operation of the centrifuges in
– areas of “zone 1”, i.e. in areas in which dangerous explosive atmosphere is
occasionally present,
– areas of “zone 2”, i.e. in areas in which dangerous explosive atmosphere
are rarely and briefly present,
is only admissible when the centrifuge is equipped for use in explosion-
hazarded areas.
• Only units designed for application in "ex" zones are allowed to be operated in
potentially explosive areas.
• All the electric apparatus of the centrifuge/plant, i.e. motor controls, valve con-
trols, electric heaters, heater control units, electrically operated valves must
be protected accordingly or, if in standard design, must be installed in a sepa-
rate room outside the explosion-hazarded area.
• Supervisory equipment on the centrifuge such as pressure switches, flow de-
tectors and temperature switches must be connected to intrinsically safe
Eex(i) electric circuits.
• In the area close to the centrifuge, take the preventive measures provided
under "primary" explosion protection” (ventilation, etc.).
• Feed the centrifuge only with

product according to the order
specification.
Fig. 55
• For carrying out repair or maintenance work on the centrifuge installed

in a potentially explosive area, be sure only to use special ignition-
preventing tools.

34 2060-9001-325 / 0414
• Before using the supplied special tools in potentially explosive areas, check
the environment of the centrifuge for an explosive atmosphere.
1.7.1 Classification of the centrifuge / plant

The centrifuge/plant complies with the requirements of Group II, Equipment
Category 3 in accordance with the Directive 94/9/EG. The respective tempera-
ture class is specified in the technical documents.
1.7.2 Obligations of the operator

The operator
• must assess the explosion risks and carry out the zone classification.
• must ensure that the centrifuge/installation is correctly erected and tested be-
fore commissioning.
• is responsible for the safety aspects of his centrifuge/installation.
The correct and proper condition of the centrifuge/installation must be main-
tained by regular testing and maintenance.
1.7.3 Before operating the centrifuge in potentially explosive areas

• Read and follow the instructions given in the manual for the Inert gas control
unit!
• Carry out voltage equalization.
• Fill the siphons.
• Purge the hood and drive spaces of the machine with inert gas.
• Fill the sealing chamber and the hood and drive chambers with inert gas, up
to operating pressure (to be checked on the pressure gauge!).
The operating pressures depend on the machine type and can be read in the
machine-specific installation diagrams.
• Check for tightness in compliance with the machine specifications.
1.7.4 Operation of the centrifuge in potentially explosive areas

• Keep the centrifuge inert-gas blanketed during operation.
• Safe operation of the centrifuge can be assured by maintaining a slight inert-
gas overpressure at any point in the gas-tight housing. This is to prevent oxy-
gen from penetrating inside the housing.
However, make sure not to exceed the max. permissible inner pressure
of the centrifuge housing!

2060-9001-325 / 0414 35
1.7.5 Shut-down and “Emergency-Off"
• For shut-down of the separator refer

to the chapter "Operation" of this
manual and follow the start-up and
shut-down instructions.
Fig. 56
After shut-down of the machine and when the bowl has stopped rotating,
the inert-gas supply must remain in operation until cooling-down to room
temperature.
Otherwise a vacuum will form while the gas volumes in/around the machine are
cooling down. This vacuum will cause oxygen to be sucked into the centrifuge.
A deflagration or an explosion might happen.
1.7.6 Standards and guidelines

The following standards, guidelines and regulations must be observed when us-
ing equipment in explosion-hazarded areas:
• Directive 94/9/EG (ATEX 95)

Equipment and protective systems for correct usage in explosion-hazarded
areas.
This Directive describes fundamental safety requirements and test proce-
dures for application outside of explosion-hazarded areas, which, however,
with regard to explosion hazards, are necessary for the safe operation of
equipment and safety systems or contribute to it.
• Directive 1999/92/EG (ATEX 137)

Protection of safety and health of the employees when working in explosion-
hazarded areas.
This Directive is directed at the operator and contains, among other things,
the necessary specifications and definitions for zone classification required for
assessment.

1.8 Corrosion
Corrosion can also affect bowl parts made of stainless steel. This corrosion can
be flat-spread or pit- or crack-shaped and merits special attention.
Corrosion on stainless steel bowl material should be examined thoroughly and
documented.
Flat-spread corrosion can usually be measured (reduction of wall thickness)
Pit- or crack-shaped corrosion cannot be measured without the risk of damage.
At the initial stage pit-shaped corrosion is generally caused by chlorine ions.
Depending on the stressing of the part, pit-shaped corrosion can result in crack-
shaped corrosion.
Possible formation of pit-shaped cor-

rosion.
Fig. 57
Such pittings can only be investigated by a materials expert.
In case of crack-shaped corrosion attack with or without superposed flat-

spread and pit-shaped corrosion on main bowl components, the machine
must be shut down immediately.
Contact your nearest Westfalia Separator representative for a thorough exami-

nation.
Pittings
Pittings which are close together or
form a linear pattern can signify crack
formation beneath the surface.
Such pittings should be investigated by
a materials expert.
Fig. 58

38 2060-9001-325 / 0414
1.9 Erosion
Erosion is caused by solid particles in the process liquid.
These solid particles grind marks into the surfaces with which they come into
contact.
The following factors favour the occurrence of erosion:
• hard solids particles
• high throughput capacities
The first signs of erosion should be carefully observed and documented. Ero-
sion can deepen rapidly, thereby weakening the bowl material.
Contact your nearest Westfalia Separator representative for a thorough exami-

nation. Information on the nature of the damage can be provided by photos,
plaster casts or lead molds.
Fig. 59
The surfaces most susceptible to erosion are:
1) the bottom of the distributor, the rising channels and the ribs,
2) the centripetal pump (cavitation),
3) all surfaces in the area of the solids discharge ports,
4) the nozzles.

2060-9001-325 / 0414 39
Signs of erosion which you should

immediately report to your nearest
Westfalia Separator representative:
• The bottom of the erosion mark has
a radius smaller than 1 mm (large
notch effect).
• The depth of erosion mark exceeds
1 mm (0.04 inch) at the deepest
point.

2.1 Dimensioned drawing of the separator

• Refer to the project-specific dimensioned drawing.
• Pay attention to the installation guidelines.
2.2 General
The machine described in this manual is a high-speed centrifugal separator with
self-cleaning bowl.
"Separation" means the separation of liquid mixtures which consist of two liq-
uids, with simultaneous removal of the solids contained in the liquids.
"Clarification" is the removal of solids from a liquid.
Prerequisite for treatment technology (separation) is that the components of the
product
– can be separated mechanically,
– have different densities and
– do not emulsify.
2.3 Separator
The separator
• is equipped with a self-cleaning disk bowl,
• is used for the clarification and separation of liquid mixtures.
• operates with regulating rings (see section 2.6).
The most important part of the separator is the bowl. The bowl
• is configured as a purifier bowl at the factory,
• can – depending on the application – be converted to operate as a purifier
bowl or clarifier bowl.
Conversion of the purifier bowl into a clarifier bowl and vice versa is possible
in a few simple steps (see Fig. 61).

The product is conveyed to the separator via a separate pump.

The product is fed in through a closed line system (1).
Both purified liquids are discharged under pressure (2, 3) by the double centrip-
etal pump (4, 5).
The solids collected in solids holding space (6) are automatically led off into a
tank at regular intervals.
The control and monitoring unit ensures unmanned operation.

2.4.1 Bowl
Fig. 64

1 Bowl produces high centrifugal forces through rotation
making possible separation and clarification.
2 Distributor accelerates the product fed in through feed A to
the rotational velocity of the bowl and then con-
veys it into the disk stack.
3 Disk stack • splits the liquid mixture consisting of a light
and heavy phase, e.g. oil-water, into its com-
ponents.
• consists of a large number of conical disks
positioned on top of one another.
Each disk is provided with spacers so that pre-
cisely defined interspaces are formed between
the individual disks.
The smooth disk surfaces facilitate sliding of the
solids and hence self-cleaning of the disks.
Separation chamber The separation space consists of a large number
of parallel chambers of low height. This produc-
es very small radial sedimentation paths for the
product.
Solids collect on the upper wall of each disk interspace

and slide down into the solids holding space.
4 Solids holding space collects the solids separated in the disk stack.

2.4.2 Bowl hydraulics
A B
Fig. 65
A Separation – Bowl closed

B Ejection – Bowl open
1 Operating liquid In the rotating bowl the incoming, rotating oper-

(usually water) ating liquid generates a high centrifugal pres-
sure. This pressure is utilised for actuating the
annular piston and sliding piston which closes
and opens the bowl.
2 Annular piston • is inside the bowl bottom,

• rotates with the same angular velocity as the
other bowl parts,
• is axially movable.
3 Sliding piston • is located inside the bowl bottom,

• rotates with the same angular velocity as the
other bowl parts,
• is axially movable.

Closing the bowl (separation)
A B
Fig. 66

After starting the separator the solenoid valve for operating liquid is actuated
with the aid of the control unit, and the bowl is closed as follows:
1 Operating liquid • flows into the injection chamber 4 of bowl

bottom 5 and
• from there through feed holes into closing
chamber 6.
This initiates closing of the bowl.
2 Annular piston • moves into closed position.
3 Sliding piston • is raised due to the hydrostatic pressure in

closing chamber 6.
• is pressed against the gasket 7 of bowl top
due to the hydrostatic pressure and
• closes the bowl.

Opening the bowl (ejection)
A B
Fig. 67

The solenoid valve for operating liquid is opened with the aid of the control unit,
and the ejection cycle is triggered as follows:
1 Operating liquid • flows first into injection chamber 4 and

• from there into opening chamber 8.
2 Annular piston • rises and

• empties closing chamber 6.
3 Sliding piston • moves downwards and

• opens the ejection ports in bowl bottom 5 for
the separated solids 9.

1 Lower centripetal • discharges the separated liquid under pres-

pump (light liquid) sure.
• is firmly connected to hood 2 of the separator.
• The disk provided with channels

dips into the liquid rotating with the
bowl.
• The liquid
– is pared off by the centripetal
pump and
– flows through its spiral channels
from the outside to the inside.
By this means the kinetic energy is
converted into pressure energy
which makes possible discharging
the liquid under pressure.

1 Drive motor drives the separator.

Power transmission to the bowl spindle is via the
centrifugal clutch to the motor belt pulley and via
the drive belt.
2 Centrifugal clutch • ensures power transmission between motor,

drive belt and spindle.
• accelerates the bowl gradually to rated
speed;
• is gentle on the drive belt and motor.
For more details see section 4.5 - centrifugal
clutch.
3 Drive belt transfers the drive power of the drive motor 1 to

the bowl spindle 4.
Regularly check the seat and condition of the
drive belt. The inspection and replacement inter-
vals are given in the maintenance schedule (see

2.6 The regulating ring

(using oil purification as an example)
Function of the regulating ring

Optimum dewatering of oils containing water is only possible if the bowl is cor-
rectly adjusted to the difference in density between the oil and the water.
The regulating ring with the correct inner diameter, i.e. with the diameter that
corresponds to the density difference between the oil and water, should there-
fore be selected from the set of regulating rings (with different inner diameters)
supplied with the separator and fitted in the bowl.
The inner diameter of the regulating ring to be selected can be determined with
the aid of the diagram or by experiment. The rule of thumb is:
• small regulating ring for heavy oil,
• large regulating ring for light oil.
2.6.1 Determining the size of the regulating ring with the aid of the
diagram
(using oil purification as an example)
The diagram can be used to determine
– the inner diameter of the regulating ring and,
– if desired, the density of the oil
for a given separating temperature, provided that the density of the oil is known
o o
at a temperature between 15 C and 90 C.
Example
Given:
o
ρoil 20 °C = 0.746 kg/dm
3
– Density of oil at 20 C
o
– Separating temperature t = 70 C
To be determined:
– Inner diameter of regulating ring d = ?

ρoil 70 °C = ?
o
Determined:
– Inner diameter of the regulating ring
d = 150 mm
according to the diagram
o
ρoil 70 °C = 0.714 kg/dm
3
according to the diagram
If no regulating ring with the determined inner diameter is available, a smaller

ring can be machined to the required size. Before doing that, however, check by
experiment whether the regulating rings furnished with the separator are ade-
quate for optimum dewatering.

2.6.2 Determining the regulating ring by experiment

(explained using the example of oil purification)
One always selects the next widest regulating ring to avoid emulsification.
If the regulating ring is too wide
– the water discharging through the water outlet will contain oil.
If the regulating ring is too narrow
– emulsification is likely to occur or
– the oil discharging from the clean oil discharge will contain water.
The water may look dirty or milky. The colouring comes from washing the oil.
A separating zone forms in the bowl between the light and heavy liquid whose
center is the separating line.
When the right regulating ring has been selected, the separating line will be at
the outer rim of the disks.
After opening the bowl, the separating zone can be seen by the almost always
visible separating line between water and oil on the underside of the separating
disk.
Correctly selected regulating ring

• The separating line between water
and oil is situated at the outer rim of
the disks.
Effect:
– The discharging clean oil is free
from water.
– The discharging water is free from
oil.
Fig. 76
Regulating ring too wide

• The separating line between water
and oil runs
– far outside the disks and
– too close to the outer edge of the
separating disk.
Effect:
– The discharging clean oil is free
from water.
– The discharging water contains oil or
– oil breaks the water seal.
Fig. 77

2060-9001-325 / 0414 59
Regulating ring too narrow

• The separating line between the
components runs further inwards.
Effect:
– The discharging clean oil contains
water.
– The discharging water is free of oil.
Fig. 78
Note:
In the case of a perforated disk stack, the separating line is located on the pitch
circle diameter of the rising channels.

2.7 Supervisory equipment

The separating process is monitored and controlled by an automatic control unit.
For further details, refer to the control unit manual.
2.7.1 Vibration monitoring (Option)

The separator is protected against inadmissibly high vibrations by means of an
electronic vibration monitoring system.
Fig. 79 Installation example
1 Vibration pick-up • is installed at the upper part of the frame.

• converts the separator vibrations into electric
signals.
2 Terminal box • is mounted at the lower part of the frame.
3 Vibration monitoring • is installed in the control cabinet.
unit • evaluates the signals coming from the vibra-
tion pickup.
The evaluation of the signal – depending on the version – takes place
in the control cabinet, on the control unit or directly on the vibration
pickup.
When the limit value or values are exceeded, an alarm and follow-up
measures are triggered and the separator motor switches off automati-
cally.
The operating status can be read off on the control unit.
ATTENTION!
Pay attention to the following instructions and plans:
• instruction manual of the vibration monitoring system
• instruction manual of the control unit
• terminal allocation in the terminal diagram of the control cabinet
• circuit diagram

2060-9001-325 / 0414 61
2.7.2 Speed monitoring (standstill checking device)

The speed monitoring serves to
• display the bowl speed.
Speed deviations of up to 5 % are permissible.
• Monitoring of:
– speed drop or exceeding max. speed
– exceeding the starting time
Fig. 80

3.1 Technical information

Take note of the following sections:
3.1.1 Separation
The best separation effect is obtained with low viscosity of the product to be
separated.
The separator operates economically with the separating temperatures and ca-
pacities specified by us.
In the case of deviating products
– see sales documents or diagrams
– or inquire at the factory.
3.1.2 General information on bowl ejection

The bowl is ejected automatically at full speed during the program sequence.
The ejection time is determined by the preset separating time.
For determining the separating time see 3.5.
Sequence of an ejection (example)

1. Separating time has elapsed.
2. Product feed valve is closed.
3. Displacement water displaces the light liquid.
4. Operating water opens and closes the bowl hydraulically at full bowl
speed.
5. Waiting time for speed recovery.
6. Filling water supply.
7. Product valve is opened.
8. Separating time resumes.
Displacement
• When separating, the loss of feed liquid unavoidable during ejection can be
reduced to a minimum by displacing the feed liquid with water before sludge
ejection takes place (especially important when processing valuable feed liq-
uid).
• The duration of displacement water supply is given in the timer overview (see
control unit manual).
• If the displacement time is too long, water will discharge through the light liq-
uid outlet.
• If the displacement time is too short, part of the product remains in the bowl
and is lost during desludging.

2060-9001-325 / 0414 77
Flush ejection
If the solids can’t be completely ejected,
– due to an excessively long dwell time in the bowl or
– are stuck to firmly on the wall of the solids holding space due to the solids
properties,
• either the separating time must be shortened or
• a flush ejection must be carried out after the total ejection by filling the bowl
with water or product and emptying it again.
Program control
• "Displacement", "ejection", "filling" and "flush ejections" at precisely defined
intervals are best carried out with the automatic control unit.
• The discharges can be monitored.
• Faults can be signalled visually or audibly.

78 2060-9001-325 / 0414
3.2 Before start-up
Note:
• Safety precautions in chapter 1.
• Instruction manual of the corresponding control unit.
• Instructions “Settings and malfunctions”
• Instruction manuals for other auxiliary equipment
• Process-related deviations are possible
(refer to the order-specific operating data sheet!)
3.2.1 Before the first start-up – after maintenance and repair
ATTENTION!
In order not to endanger the operating safety of the separator, keep
to the recommended maintenance intervals.
If the bowl has been out of operation for longer than 6 months (e.g. due
to a long standstill period or storage),
• check all bowl parts as specified in the maintenance schedule (table
“Maintenance after 4000 operating hours or after 6 months at the latest”).
• Replace if necessary.
If the separator has been out of operation for longer than 12 months (e.g.
due to a long standstill period or storage),
• check all separator parts in accordance with the maintenance schedule
(table “Maintenance after 8000 operating hours or after 1 year at the lat-
est).
• Replace if necessary.
Check that
• the machine is correctly assembled.
• the sight glasses in the frame for observing the drive belt are clean.
• the drive chamber is filled with oil in accordance with section 4.2.3.
• the bowl height is correct (see section 4.7.1).
• the bowl can be rotated by hand.
• the hex head screws on the hood are tight (see 4.4).
• the handle connection piece is tightly bolted to the centripetal pump (see 4.4).
• the hoses and hose pipes are undamaged and connected (see section 4.2.2).
• the feed and discharge lines are connected (see 4.4).
• the supervisory equipment is complete and functional.
• the motor is correctly connected.
• the motor is properly secured.

2060-9001-325 / 0414 79
3.2.2 Before every start-up
Check that
• the machine is correctly assembled.
• the sight glasses in the frame for observing the drive belt are clean.
• the drive chamber is filled with oil in accordance with section 4.2.3.
• the hex head screws on the hood are tight (see 4.4).
• the handle connection piece is tightly bolted to the centripetal pump (see 4.4).
• the hoses and hose pipes are undamaged and connected (see section 4.2.2).
• the feed and discharge lines are connected (see 4.4).
• the supervisory equipment is complete and functional.
• the motor is properly secured.
3.3 Starting the separator

• See section 3.2.1 or 3.2.2.
• Switch on control unit.
• Switch on the separator motor.
Compare the starting current and starting time with the diagram (Section
4.1.3) until the bowl reaches the speed specified on the separator nameplate.
Note on control system D10:
The run-up phase of the separator motor is signalled by slow flashing of the
LED in the “Status Separator” key.
Note on control system E40:
The run-up phase of the separator motor is displayed by a graphical repre-
sentation of the separator motor in the control unit. Refer to the graphic repre-
sentation for "motor run-up and post-run" in the control unit manual.
ATTENTION! Before the first start-up – after maintenance and repair work
on the separator –
• check the direction of rotation of the bowl.
The bowl must run clockwise viewed from above.
The direction of rotation of the bowl is

correct if the drive belt is turning
clockwise (observe through the sight
glass in the frame).
When the direction of rotation is incor-
rect the motor connections must be
reversed by an authorised specialist.
Fig. 85
• Switch on the product feed pump (option).

– Ensure that the product feed valves to the suction and pressure sides are
open!

80 2060-9001-325 / 0414
ATTENTION! Before the first start-up – after maintenance and repair work
on the product feed pump –
• Check the direction of rotation of the product feed pump.
The direction of rotation of the product feed pump is correct when the fan
wheel of the pump motor rotates clockwise.
• Put the preheater in operation (option).
Pre-conditions:
– Steam or thermal oil feed and discharge valves are open!
– Electric preheater is switched on!
• Open the product discharge valve in the product discharge line (option).
• Open the shut-off flap in the solids

discharge (option).
1 Shut-off flap
2 Solids tank
3 Solids discharge
Fig. 86
• Start the program.

Pre-conditions:
– Continuous lighting of the LED in the “Status Separator” button.
– The specified separating temperature has been reached.
– The solids tank has been released (level switch LSHH).
– The solids tank is empty.
• After the product feed valve has automatically opened
– Set the backpressure in the product discharge line to approximately 1 –
2 bar (see order-specific operating data sheet).
– Adjust the desired throughput capacity; while doing so, maintain the back-
pressure in the product discharge line within the specified range.
ATTENTION!
• Check solids discharge and frame drain; no oil may flow here during the sep-
arating process!

2060-9001-325 / 0414 81
3.4 Monitoring of operation

The machine is monitored largely by the separator control.
Operations to be carried out regularly:

• On your daily round, especially during the first 1500 operating hours, pay at-
tention to the following:
– Oil level
– Temperatures
– Pressures
– Leakage
– Vibrations
– Current consumption
– Starting time
– Hoses and hose pipes
– Pipe joints
• Keep to the maintenance schedule (see 4.2.1)!
• Inspection
We, therefore, recommend in your own interest to have your separator in-
spected by our service engineers once a year. These checks help to
– maintain the operating safety of the machine and
– avoid unscheduled downtime.
Im p o rta n t!
• Regularly check plant components such as hose pipes, sight glasses for signs
of aging and mechanical damage.
• Damaged plant components must be replaced immediately by new parts.

82 2060-9001-325 / 0414
3.5 Setting the separation time

When using time-dependent automatic control programs, accurate setting of the
separation time (time between ejection cycles) is only possible if the throughput
capacity and solids loading in the feed remain constant. If this is not the case, it
may be necessary to correct the settings during operation.
The separating time depends on
• the preselected operating mode (partial or total ejection mode),
• the solids loading in the feed,
• the consistency of the solids,
• the effective solids space volume in the bowl,
• the separator throughput.
Given constant conditions, the separating time can be determined by calcula-
tion.
3.5.1 Mathematical calculation

Example for mathematical calculation of the separating time:
(1)
Given: Solid content p = 0,05 %
Solids holding space volume V = 11 l
Solids holding space given 75 % utilisation V' = 8.25 l

(1)
Throughput capacity Vo = 7 000 l/h
Wanted: Separating time t = ? min
The separating time to be set is calculated as follows:
V’ 8.25
t = ——— • 60 • 100 = —————— • 6 000 = 141 min = 2.35 h
V° • p 7 000 • 0,05
(1)
Solids content and throughput capacity must be determined on site or taken from

* WS standard
The separator is driven by a three-phase AC motor via a centrifugal clutch and
the drive belt.
The specified motor ratings are minimum values which are based on the in-
creased starting current. Since the current consumption of the motor drops after
start-up, overloading of the motor during operation is not possible.
The starting time depends on the
– flywheel effect of the bowl,
– number of clutch shoes used,
– condition of the clutch shoes.
The starting current can peak at about 1.8 - 2 times the rated current (see start-
up diagram). This is to be considered when selecting switches, lead-in wires
and fuses.
The motor
– can be started direct online (WS standard) or via a motor control for star-
delta switching (Ex-zone).

102 2060-9001-325 / 0414
– is protected against overheating by thermal overload releases or a PTC

thermistor as sole protection.
(As WS standard, the motor is protected against overheating by three PTC
thermistors).
– can be equipped with a frequency converter if requested by the customer.
When using thermal overload releases, the motor has to be protected as fol-
lows:
– during operation by a release set to the rated current and
– during start-up by a second release set to 1.8 - 2 times the rated current.
The release set to the rated current must be bridged during start-up.
Note:
• The temperature feelers must be connected to a commercial tripping device.
• External voltage higher than 2.5 volts must not be applied to the connection
terminals of the temperature feelers.
• When testing for continuity, use an ohmmeter and not a test lamp.
Electrical connection
CAUTION: Danger to life and limb through electric current!

There might be residual voltage!
In the case of motors with space heaters, residual voltages in the motor
terminal box are possible despite switched off main switch.
Prior to working on the motor:

• Refer to the motor nameplate.
• Refer to the motor instruction manual.
• Refer to the frequency converter manual (if applicable).
Germany in accordance with the rules and regulations of the VDE (Verband
Deutscher Elektrotechnik/ Association of German Electrical Engineering) or of
the local electric power company.
• Any work on the motor may be carried out by an authorised electrician only.
• Connect the motor.

Refer to the motor instruction manu-
al.
Fig. 98 Connection schematic
The terminal board in the terminal box can be connected in star or delta.

heaters, refer to the motor manual.
Shipboard operation
• When operating the machine on board of ship, pay attention to the installation
guidelines issued by the respective classification societies.
• When using ship wiring cables, cable entry must be by means of marine-type
glands.
In the case of explosion-proof motors:

• Strictly adhere to the prevailing local rules and regulations for operating in po-
tentially explosive areas.
• The statutory regulations for electrical apparatus in explosion-hazarded areas
must be observed (see section 1.7.6).

4.1.4 Direction of rotation of the bowl
• Fill the drive chamber with oil up to

the half way mark on the sight glass.
• Switch on motor.
Fig. 101
The bowl must rotate in clockwise direction when looked at from above.
The direction of rotation of the bowl is

correct when the drive belt rotates
clockwise (check through the sight
glasses in the frame).
When the direction of rotation is incor-
rect the motor connections must be
reversed by an authorised specialist.
Fig. 102
In case of frequency converter

In case of frequency converter operation:

The frequency converter is equipped with a reliable frequency limitation to pre-
vent operation at inadmissibly high bowl speeds.
CAUTION!
• Operate the separator with fre-
quency converter, speed monitor-
ing device and hardware-
controlled speed shut-off device.
• Do not under any circumstances
manipulate the frequency con-
verter to exceed the permissible
bowl speed (see nameplate)!
• Check from time to time that
– the bowl speed (see nameplate)
and
Fig. 105 – motor frequency (see nameplate
and frequency converter display!)
coincide with the separator speed.

2060-9001-325 / 0414 107
4.2 Maintenance and lubrication
• Special care must be taken when performing maintenance and lubrication

work.
Conscientiously performed maintenance and lubrication operations improve
the service life of the separator.
• In the case of accessories (motor, product pump, preheater, solenoid valve
block, etc.) the manufacturer’s maintenance and lubrication instructions must
be observed.
• Maintenance and repair work may only be carried out by persons
– who provide evidence of familiarity with the state of the art as a result of
briefings and training.
– who are adequately qualified for performing the work and for checking it if
required.
• Electrical work may only be carried out by an authorised electrician!
• Use only genuine spare parts from GEA Westfalia Separator Group.
The genuine spare parts are listed in the spare parts catalog.

108 2060-9001-325 / 0414
4.2.1 Maintenance schedule
ATTENTION!
The following maintenance intervals are recommendations which apply only for normal operating
conditions.
Negative operating conditions (e.g. low-grade fuel, excessively high temperature, strong vibrations,
frequent starting and stopping of the separator etc.) can necessitate shorter maintenance intervals.
To assure correct functioning and operating safety,

• in case of non-routine shut-down, see section 3.7 - manual operation.
• Pay attention to the following points during servicing:
– Oil level – Vibrations
– Temperatures – Current consumption
– Pressures – Starting time
– Leakage – Hose and hose pipes (see 4.2.2 ).
• Before assembling, grease the guide and contact surfaces of the main bowl components. (1)
• in the case of frequent starting and stopping of the separator, shaft-driven alternator operation and in power plants, the
condition of the clutch shoes must be checked more often than stated in this schedule. It is not possible to state a defini-
tive time. We recommend checking the clutch shoes after 1000 operating hours or after 2 months at the latest.
• We recommend having the separator checked by a WS service engineer once a year.

4.2.6 Comments on table of lubricating oils for separators from GEA Westfalia Separator Group
Faultless functioning of separators very much depends on the proper type of lubricating oil used, since a
high grade oil, selected to meet all service requirements, will minimize the wear, thus extending the ser-
vice life and increasing the operating safety.
For the lubrication of our separators we recommend using the oils specified under "GEA Westfalia Sepa-
rator Group" since they are subjected to continuous quality checks. Oils proposed from some firms are
not subjected to these tests.
Therefore, GEA Westfalia Separator Group cannot give a performance guarantee for those oils.
Be sure to select only high grade solvent refined products.
The specified oil types meet the requirements according to DIN. Under unfavourable operating condi-
tions, e.g. high temperatures, the quality of the oils may be insufficient so that more efficient oils, e.g.
synthetic oils, must be used. If necessary, consult GEA Westfalia Separator Group.
For the different separator types and oil types the viscosity ranges are specified in the table of lubricating
oils.
o o
The separator working temperature is normally above 80 C (176 F). At those temperatures some oils
age quickly, so that they have to be changed prematurely.
Be sure not to use lubricating oils with viscosities lower than those specified in the table. Due to the pos-
sibility of the oil film breaking down, oil of too low a viscosity will give insufficient lubrication, resulting in
increased wear. However, oils with a slightly higher viscosity than specified may be used.
Please note that the viscosity classes SAE 30, 40 and 50 (SAE = Society of Automotive Engineers) cover
large viscosity ranges. However, the lower limits for the viscosity ranges defined for the individual separa-
tor types may not be undershot.

ATTENTION!
• Before assembling the bowl, ensure that the guide and bearing surfaces of
the bowl parts are clean.
• Grease the guide surfaces as specified in the lubrication schedule (see 4.2.4).
• Some bowl parts have to be fitted in

fixed positions relative to one anoth-
er.
• Locking devices and alignment
marks must be in perfect condition.
ATTENTION
The bowl must not be operated un-
less this is the case!

4.5 Motor and centrifugal clutch

The centrifugal clutch
• ensures power transmission between motor, drive belt and spindle.
• brings the bowl gradually to rated speed,
• eliminates premature wear to drive belt and motor.
Note that the driving effect of new clutch shoes will improve after several starts.
Smoking of the clutch during the first few starts is perfectly normal and will dis-
appear after a short time of operation.
If the bowl reaches its rated speed in

less than 3 minutes (see nameplate)
resulting in an inadmissibly high motor
current consumption during start-up,
(Imax >1.8 x IN),
• reduce the number of clutch shoes,
• be sure to keep the clutch shoes
evenly spaced.
Fig. 276
• Wear to the clutch shoes depends on

– number of start-ups,
– ejection frequency.
• Check the condition of the clutch shoes from time to time (see 4.2.1 - Mainte-
nance schedule).

• Always replace all clutch shoes simultaneously.
Never replace individual clutch shoes!
