1.1 Correct usage

The separator is designed
• in accordance with the chemical and physical properties of the product speci-
fied by the customer and
• in accordance with the method of application of the separator agreed with
Westfalia Separator.
In particular, products not conforming to the specifications on the nameplate
may not be used.
Any mode of operation deviating herefrom is not proper and correct.
Prior to any intended deviation from the agreed operating mode, it is therefore
imperative to obtain the consent of Westfalia Separator.

1.2 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.

Before carrying out work, dis-

connect power to the all compo-
nents of the monitoring system!
Risk of injury due to electrical voltage
and unintended start-up of the separa-
tor!

Before carrying out work on the

separator and electrical plant com-
ponents:
• Make sure the separator is at a
standstill.
Fig. 4 • Switch off all electrical appliances
via the main switch,
• Lock the installation to prevent it
from being accidentally switched on.

Danger o life and limb through

rotating machine parts!
• Do not loosen any part and do not
carry out maintenance or repair
work on the separator before the
separator is at a standstill.
Methods of how to check standstill
are described in the machine docu-
mentation.

Fig. 5

Warning of unusual noises or

vibrations!
When unusual noises or vibrations oc-
cur on the separator:
• Immediately shut down the separa-
tor with filled bowl via “emergency-
off”.
• Never trigger a bowl ejection!
• Evacuate the room.
• Do not re-enter the room until the
centrifuge has come to a standstill.

1.3 Basic operating principles

Separators 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. 9

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, whe-
reas 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 separator.

1.4 Bowl speed and product

The max. permissible bowl speed is an important parameter when rating the se-
parator. It depends on the chemical and physical properties of the product such
as
• temperature, if higher than 100 °C (212 °F) or lower than 0 °C (32 °F),
• density of the fluid and solid components,
• aggressiveness of the product as regards corrosion and erosion (has influ-
ence on the selection of the bowl material).
The bowl speed is determined on the basis of these parameters allowing for an
adequate safety margin.
Before using a product with properties different from those stated when placing
the order, it is imperative to obtain the manufacturer's approval.

Mineraloil Systems GmbH 15

1.5 Demands relating to service personnel and spare parts

• Use only genuine spare parts from Westfalia

Separator.
The use of non-genuine parts leads to:
– Safety risks
– Lower durability and availability
– Increased maintenance requirement
If a safety risk arises, this may have legal con-
sequences for the responsible persons. In this
Fig. 10 case, Westfalia Separator shall assume no li-
ability or warranty.
• Deploy only well trained personnel for maintenance work, e.g. service per-
sonnel from Westfalia Separator or personnel trained by Westfalia Separator.
An incorrectly maintained/assembled machine poses a safety risk for the op-
erators.

1.6.6 Maintenance and repair

Unfavourable operating conditions may require shorter maintenance intervals.
The factors listed below are unfavourable because they either attack the
separator material directly or impair the lubrication/cooling system:
• aggressive product (chemical or physical)
• high product temperature
• product with grease decaying properties
• environment: temperature, dust and vapours

Particularly highly stressed parts such

as
• bowl lock ring,
• bowl bottom,
• bowl top and
• other bowl parts with a large outer
diameter
must be regularly checked to ensure
safe, reliable and efficient operation.

Fig. 35

Timely maintenance and replacement of worn or damaged machine parts is es-

sential for safe operation of the machine.

Maintenance and repair work may only be carried out by the customer to the ex-
tent as 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 in-
spected by our service engineers at regular intervals. Such inspections will keep
your separator working reliably and prevent undesirable shut-downs.

Prior to carrying out any work on

the separator and on electrical plant
components:
• ensure that the separator is at a
standstill,
• switch off all electrical appliances
via the main switch,
• secure installation against unin-
tended re-starting with locking de-
vices.

Fig. 36

2057-9001-020 / 0905
Westfalia Separator
Mineraloil Systems GmbH 25

• Do not loosen any part, nor carry

out any maintenance or repair
work before the bowl has come to
a standstill.
Check for standstill as described
under “Bowl”.

Fig. 37

• Do not climb onto or stand on the

machine or parts of the machine.
• Make provision for and use a sturdy
working platform.

Fig. 38

• Place dismantled machine parts on

a suitable base, e.g. rubber mat.
• Take steps to prevent machine parts
from overturning and rolling away.

• Do not heat bowl parts with the

naked flame.
• Bowl parts must never be welded.
This also applies for hood and so-
lids collector parts of steam-
sterilizable separators.
• Even during cleaning the bowl parts
the temperature must not exceed
100 °C (212 °F).

Fig. 40

• Load-carrying equipment such as lif-

ting devices for
– bowl or distributor,
– chains etc.
may only be used for work routines
as described in this instruction man-
ual.
• Do not use damaged or incomplete
load carrying equipment.

Fig. 41

• All load suspension devices have to be checked for completeness and for
possible damage at least once a year.
• In addition, when using load suspension devices and hoists, the applicable
legislation and safety rules have to be strictly observed.

• Collect dripping oil to prevent dan-

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

1.7 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.

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.

1.8 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. 45

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.

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.

2.3 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.

2.4 OSD ...-0136-... and OSD …-0196-…

The separators OSD ...-0136 and OSD ...- 0196 with UNITROL system
• are equipped with a self-cleaning disk-type bowl,
• are applied for clarification and purification of fuel oil (up to a density of 1.01
g/ml) and lube oil.
The separators with the UNITROL system have two inbuilt monitoring functions:
• water content monitoring system – WMS
• sludge space monitoring system – SMS
The most important part of the separator is the bowl. Depending on the applica-
tion, the bowl in design -0136- can be converted to function:
• as clarifier/purifier bowl (WMS) or
• clarifier bowl with self-thinker control system (SMS).
Conversion of the clarifier/purifier bowl into a clarifier bowl with self-thinker con-
trol system and vice versa can be done in a few easy steps:

Clarifier/purifier bowl (WMS)

The two control holes in the slope
of the separating disk must be
open!
• Unscrew threaded pins.

The two holes in the slope of the
separating disk must be closed!
• Screw in threaded pins.
• Secure threaded pins with Loctite

The fuel oil is conveyed to the separator via a separate pump.

The clarified clean oil is discharged (2) under pressure by centripetal pump (12).
The bowl is automatically opened and closed for desludging at full bowl speed
by means of a solenoid valve (19) in the operating water line.
The partial flow (9) diverted from the bowl via the separating disk (13) and the
sensing liquid pump (11) is monitored by a conductivity sensor (5).
When the sensor registers water, the solenoid valve (8) opens and the water is
discharged through the dirty water outlet (14). The separator functions as a puri-
fier.
When the conductance alters due to oil flow, solenoid valve (8) closes and sole-
noid valve (7) opens intermittently. The partial flow (9) is then recycled into the
feed (1). The separator functions as a clarifier.
The control and monitoring unit (10) guarantees unmanned operation.

The SMS system for fuel oil treatment is used for clarification in two-stage clari-
fication.
The fuel oil is fed to the clarifier by the discharge centripetal pump of the up-
stream purifier.
The clarified clean oil is discharged (2) under pressure by centripetal pump (12).
The bowl is automatically opened and closed for desludging at full bowl speed
by means of a solenoid valve (19) in the operating water line.
A small volume of liquid is diverted via separating disk (13) as a partial flow (9).
It is conveyed by the sensing liquid pump (11) to the pressure switch (6) and re-
cycled into the feed via a throttle (20).
When the sensing liquid inlet becomes blocked with water or solids accumula-
tion in the sludge space (15), the pressure switch (6) sends a pulse to the con-
trol unit (10). The automatic ejection program is initiated.
The complete treatment plant is monitored by the control system (10).

2.5.1 Bowl

Fig. 57

Pos. Designation Function

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 pro-
duces 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.

2.5.2 Bowl hydraulics

Separation Ejection
Bowl closed Bowl open
Fig. 58

Pos. Designation Function

1 Operating liquid In the rotating bowl the incoming, rotating

(usually water) operating liquid generates a high centrifugal
pressure. 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.

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:

Pos. Designation Function

1 Operating liquid • flows into the injection chamber 4 of bowl bot-

tom 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.

Pos. Designation Function

1 Centripetal pump • discharges the separated liquid under pres-

sure.
• is firmly connected to hood 2 of the separator.

• The disk provided with channels di-

ps 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.

2.5.5 Drive

Fig. 64

Pos. Designation Function

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

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 se-
parated.
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 Notes for separation with the UNITROL system

The separators with UNITROL have two inbuilt monitoring functions:
– water content monitoring system - WMS
– sludge space monitoring system - SMS

Fuel oil treatment WMS and SMS

Lube oil treatment WMS and SMS

• Select the desired operating mode on the control unit.

• Set the separating time on the control unit.
• Start the separator (see 3.2).

3.1.3 General information on bowl ejection

The bowl is ejected automatically at full speed during the program sequence.
The time at which the ejection is triggered is
• determined by the preset separating time
or
• by the solids level in the bowl,
if:
– SMS was selected on the control unit,
– the sludge space is full before the separating time has elapsed.
For determining the separating time see 3.5.

2057-9001-020 / 0905
Westfalia Separator
Mineraloil Systems GmbH 53

Sequence of an ejection (example without “Filling”)

1. Separating time has elapsed.
2. Product feed valve is closed.
3. Displacement water displaces the fuel oil to the clean oil side.
4. Operating water opens and closes the bowl hydraulically at full bowl
speed.
5. Waiting time for speed recovery.
6. Product valve is opened.
7. 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.

Flush ejection
If the solids cant be completely ejected,
– due to an excessively long dwell time in the bowl or
– are stuck too 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" and "flush ejections" at precisely defined intervals
are best carried out with the automatic control unit.
• The clean oil discharge and water discharge can be monitored.
• Faults can be signalled visually or audibly.

• Switch on the control unit.
• Check that the operating mode selected on the control unit corresponds to the
valve positioning in the system.
• Start the program.
• After the feed valves have automatically opened
– set the backpressure in the product discharge to approx. 1.5 bar;
– adjust the desired throughput;
– when necessary, correct the backpressure in the product discharge.
• Check the discharges for solids and dirty water; there must be no oil flow!

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
• Keep to the maintenance schedule (see 4.2.1)!
• Inspection
We recommend having the separator checked regularly by our specialists.
These checks help to
– maintain the operating safety of the machine and
– avoid unplanned downtime.

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.
The following times have proven appropriate in practice (examples):

Product Total ejection Partial ejection

HFO 2 h to max. 4 h 1h
MDO 6h 3h
LO mild 6 h to max. 8 h 3h
LO HD 2 h to max. 4 h 1h

3.5.1 Mathematical calculation

Example for mathematical calculation of the separating time:

Given: Solids content (1) p = 0.05 %

Solids holding space volume V = 1.5 l
Solids holding space given 75 % utilisation V' = 1.13 l
(1) o
Throughput capacity V = 2 000 l/h
Wanted: Separating time t = ? min

The separating time to be set is calculated as follows:

V’ 1.13
t = ——— • 60 • 100 = —————— • 6 000 = 67.8 min = 1.1 h
V° • p 2 000 • 0.05

(1)
Solids content and throughput capacity must be determined on site or taken from
the order specification.

3.6 Ejecting the bowl

Automatic operation

• Initiate ejection program by pressing the key ”Program 1”:

– The product feed is closed.
– Displacement
– Bowl ejection
– Speed recovery
• The product valve opens again.

Hand operation (in the case of unscheduled shut-down)

• Cut off the product feed to the separator:

– Close the product valve using the manual override.
• Eject the bowl:
– Open the operating liquid valve using the manual override for approx. 2 –
3 seconds.
• Speed recovery
– Wait for approx. 20 – 30 seconds.
• Separating mode
– Open the product valve using the manual override.

3.7 Shutting down the separator

• Switch off the preheater (if installed).
– Continue to feed product for a few minutes since the preheater continues to
heat for a short time.

Automatic operation

• End the separation program with the key "program 0"

– Two total ejections are performed automatically.

Hand operation (in the case of unscheduled shut-down)

• Close the product feed:

– Close the product valve using the manual override.
• Eject the bowl: See section 3.6.

• Close the discharges.

• Close the feed for operating water, filling and displacement water.
• Switch off the motor.
• Switch off the product pump (if installed).
• Close the stop valve in the suction side of the product pump (if installed).

Danger to life through high-speed rotating separator parts!

• Do not loosen any part of the separator before the bowl has come to a stand-
still.
The run-down time of the bowl is 90 minutes after switching off the motor
(without braking!).
Bowl standstill is indicated by standstill of the drive belt.

Standstill of drive belt

• Shine a torch through the sight
glass in the frame.
• Check that the drive belt is no lon-
ger moving.

If the sight glass in the frame is misted

over:
• Unscrew the sight glass,
• shine a torch through the sight glass
opening!
• Check that the drive belt is no lon-
Fig. 65 ger moving.

Then
• Clean the sight glass and screw it back on.

2057-9001-020 / 0905
Westfalia Separator
Mineraloil Systems GmbH 59

In the case of torn or defective drive belts or if the belts have come off:
• Do not loosen any part of the separator before the bowl has come to a stand-
still.
• Be sure to observe the run-down time of 90 minutes until dismantling the
separator!
• Applying the brake is not effective!

• Danger of injury through very hot separator parts!

When carrying out maintenance work, there is a danger of injury through hot
separator parts (separating temperatures of 70 to 100 oC (158 – 212 oF).)

4.1.1 Transporting the separator

• Attention!
Prevent accidents by using suitably rated hoists for transport and installation.

• Always transport the separator without installed bowl!

• For special tools, see section Parts list.

• Screw two eye bolts 1 into the upper

section of the frame.
• Screw double nipple 2 into the hole
in the frame.

Fig. 71

• Attach the transport ropes

– around the double nipple,
– thread through the eye bolts and
– hang them into the load hook of
the hoist as illustrated.
Wind one piece of rope twice
round the hook to prevent the ro-
pes from slipping.

• Make sure that the ropes do not

damage any machine components.

• Do not use the eye bolt of the mo-

tor to suspend the separator.

• Make sure the machine touches

down gently.

4.1.2 Installing the separator

• Before installing the separator make sure that
– sufficient space is available for operating and dismantling the machine.
– the foundation is not connected to foundations of other vibrating units to
avoid the transfer of vibrations.

• Align separator 1 with feet 2 and

plates 3 on foundation 4.
• Tack plates 3.
• Unscrew screws 5.
• Lift separator with feet (see section
4.1.1).
• Weld plates 3 to foundation 4.
• Place the separator on plates 3 and
• bolt tight with hexagon nuts 5.
• Screw tight hex head screws 6.

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 on-line,

2057-9001-020 / 0905
Westfalia Separator
Mineraloil Systems GmbH 75

– is protected against overheating by thermal overload releases or a motor

overheating protection unit.
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.
Overheating protection is only possible if PTC thermistors are built into the mo-
tor winding.

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.

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. 75

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
glass in the frame).
When the direction of rotation is incor-
rect the motor connections must be
reversed by an authorised specialist.

4.1.5 Speed and starting time of the bowl

Speed see name-plate

– for densities of the product up to
max. 1.05 kg/dm3 and
– for densities of the separated solids up to max.
1.4 kg/dm3
Starting time approx. 3 - 6 min

The bowl speed has been rated so as to ensure the operating safety of the se-
parator.
If the densities exceed those stated above, check with the factory.

• Check spindle speed (= bowl speed)

with a hand tachometer:
– Before initial start-up.

• Do not exceed the maximum

spindle running time of 1 minute!

• Make this check before installing

the bowl.

• Speed deviations of up to 5 % are

permissible.

Important instructions
• When the bowl has been removed,
no oil must spill onto the drive belt
via the spindle.
• After removing the bowl, place a
cloth over the spindle immediately.

4.3.1 Dismantling the bowl

• Switch off the main switch and lock it.

Danger to life through high-speed rotating separator parts!

• Do not loosen any part of the separator before the bowl has come to a stand-
still.
The run-down time of the bowl is 90 minutes after switching off the motor
(without braking!).
Bowl standstill is indicated by standstill of the drive belt.

Standstill of the drive belt

• Shine a torch through the sight
glass in the frame,
• check that the drive belt has stop-
ped moving.

If the sight glass in the frame is misted

over:
• Unscrew the sight glass,
• shine a torch through the sight glass
opening!
• Check that the drive belt is no lon-
Fig. 83 ger moving.

Then:
• Clean the sight glass and screw it in again.

In the case of torn or defective drive belts or if the belts have come off:
• Do not loosen any part of the separator before the bowl has come to a stand-
still.
• Be sure to observe the run-down time of 90 minutes until dismantling the
separator!
• Applying the brakes is not effective!

• Danger of injury through very hot separator parts!

When carrying out maintenance work, there is a danger of injury through hot
separator parts (separating temperatures of 70 to 100 oC).
• Avoid damage to bowl parts when fitting and removing by
– precise positioning,
– no diagonal pull!
– selecting the low lifting speed of the hoist.

• Use only suitably rated, intact hoists.

• Do not use force when removing or fitting parts.

• All bowl parts

– must be gently handled,
– always set down on a rubber mat or a wooden pallet.

4.3.2 Cleaning the bowl

It is generally not necessary to dismantle self-cleaning bowls for cleaning after
separation unless
– the nature of the product makes it necessary,
– the separator is to be shut down for a lengthy period (see section 4.9).
• Dismantle and clean the bowl for checking from time to time. See section
4.2.1 - Maintenance schedule.
• Use only a cleaning agent that is approved for the field of application!

• Do not use acid or chloric cleaning agents.

Chlorine attacks stainless steel parts.

• Dissolve dried scale with citric acid.

• For cleaning the individual disks and bowl parts

Do not use metal scrapers and metal brushes!

• Take the gaskets out of the bowl

parts.
• Clean the grooves and gaskets to
avoid corrosion in the grooves.
• Replace damaged, very swollen,
hardened or brittle gaskets immedi-
ately.

Fig. 134

• Clean the small holes for the feed and discharge of the operating liquid with
particular care to ensure trouble-free bowl ejections.

• Clean the distributor between the

ribs with the brush on the inside and
outside.
When the distributor neck is very
dirty, the feed clogs which can cau-
se overflow.

Fig. 135

• Apply a thin coat of grease to the guide surfaces and threads of the bowl
parts after drying (see 4.2.4 Lubrication schedule).
• Reassemble the bowl immediately after cleaning.

2057-9001-020 / 0905

4.3.3 Cleaning the frame

Danger to life through electrical components!

• Never rinse off the motor with a direct water jet.

• Use only a cleaning agent that is approved for the field of application!

• Do not use acid or chloric cleaning agents.

Chlorine attacks stainless steel parts.

• Dissolve dried scale with citric acid.

• Clean the inside of the upper section of the frame from time to time:
To do this:
– Refer to the maintenance schedule (section 4.2.1),
– dismantle the bowl (section 4.3.1).

• Place a cloth over the spindle.

When the bowl has been removed,
no cleaning liquid must spill onto
the drive belt via the spindle.

Fig. 136

4.3.4 Cleaning the strainer and the operating water feeding system
• The strainer and the operating water feeding system must be cleaned de-
pending on the quality of the operating water and overall load. See section

4.3.5 Important instructions

CAUTION: Danger of imbalance!

When the bowl has not been correctly assembled or is inadequately cleaned,
forces can be produced in the high-speed rotating bowl which endanger the op-
erating safety of the separator!
Therefore, the cleaning instructions (section 4.3.2) and assembling instructions
(section 4.3.6) must be exactly followed.

Pay particular attention to the following:

• Before assembling the bowl, check to be sure that the guide and contact sur-
faces of the bowl are clean.

• Grease the guide surfaces as specified in the lubrication schedule (see 4.2.4).

• When fitting the bowl parts, make

sure that the "O" marks on all parts
are aligned.
(Only then will the parts fit correctly
over arresting pins and guide ribs).

Fig. 137

• Avoid damage to bowl parts when fitting and removing by

– precise positioning,
– no diagonal pull!
– selecting the low lifting speed of the hoist.

• Use only suitably rated, intact hoists.

• Do not use force when removing or fitting parts.

• If the plant has several separators,

be sure not to interchange parts of
different bowls (danger of imbal-
ance).
The parts are marked
– with the serial number or
– the last three digits of the serial
number.

• Thoroughly clean the gasket groo-

ves of the individual bowl parts and
apply a thin coat of grease.
• After fitting check that
– the gaskets are not twisted,
– the gaskets are evenly positioned
in the groove.

4.5 Motor and centrifugal clutch

General
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 1.5 minutes (see nameplate)
resulting in an inadmissibly high motor
current consumption during start-up,
(Imax >2 x IN),
• reduce the number of clutch shoes,
• be sure to keep the clutch shoes
evenly spaced.

Fig. 225

• 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 at the same time to avoid imbalance.
Never replace individual clutch shoes!

4.6.1 Important instructions

• Switch off the main switch and lock it.

Danger to life through high-speed rotating separator parts!

• Do not loosen any part of the separator before the bowl has come to a stand-
still.
The run-down time of the bowl is 90 minutes after switching off the motor
(without braking!).
Bowl standstill is indicated by standstill of the drive belt.

Standstill of drive belt

• Shine a torch through the sight
glass in the frame.
• Check that the drive belt is no lon-
ger moving.

If the sight glass in the frame is misted

over:
• Unscrew the sight glass,
• shine a torch through the sight glass
opening!
• Check that the drive belt is no lon-
Fig. 227 ger moving.

Then
• Clean the sight glass and screw it back on.

In the case of torn or defective drive belts or if the belts have come off:
• Do not loosen any part of the separator before the bowl has come to a stand-
still.
• Be sure to observe the run-down time of 90 minutes until dismantling the
separator!
• Applying the brake is not effective!

• Danger of injury through very hot separator parts!

When carrying out maintenance work, there is a danger of injury through hot
separator parts (separating temperatures of 70 to 100 oC).
• Avoid damage to drive parts when fitting and removing by
– precise positioning,
– no diagonal pull!
– selecting the low lifting speed of the hoist.

• Use only suitably rated, intact hoists.

• For special tools, see section Parts list.

• For standard tools, see section 4.11.
• Do not use force when removing or fitting parts.
• Treat all drive parts
– Treat gently.
– Always set them down on a rubber mat or a wooden pallet.

2057-9001-020 / 0905
Westfalia Separator
Mineraloil Systems GmbH 135

• Before fitting the drive parts

– Thoroughly clean and dry the drive chamber.
Use only a cleaning agent that is approved for the field of application!
– Check the ball bearings of the spindle and centrifugal clutch.
Use only the ball bearings specified in the parts list!

To avoid bearing damage,

• always operate the separator with installed bowl!

Guide to ordering spare parts

A rapid and correct supply of spare parts can only be guaranteed if your order
includes the following details:

• Separator model see nameplate

e.g. OSD 35-0136-067

• Serial-No. see nameplate

e.g. 9000-223

• Designation see parts list

e.g. frame

• Part-No. see parts list

e.g. 2050-1100-020
The part number is also marked on almost all the
individual parts.

• Bowl S/N see bowl lock ring, bowl bottom or bowl shell
if different from the machine serial number.

Only required when ordering pare parts for pump and pump connection parts:
• Model and number of see pump nameplate
pump

The details must be complete when the part number ends with a letter (e.g.
2050-6600-L), since this indicates that the parts are available in different de-
signs.

• Use only genuine spare parts from Westfalia

Separator.
The use of non-genuine parts leads to:
– safety risks,
– less durability and availability,
– increased service requirement.
If a safety risk occurs, this may have legal con-
sequences for the responsible persons. In such
Fig. 320 cases, Westfalia Separator accepts no liability
or warranty claims.

7.1.1 Comments on table of lubricating oils for separators from Westfalia Separator

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 to use the oils specified by us since continuous qual-
ity checks are performed by Westfalia Separator. Oils proposed from some firms are not subjected to
these tests.
Therefore, Westfalia Separator 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 Westfalia Separator.
For the different separator types and oil types the viscosity ranges are specified in the table of lubricating
oils.
The operating temperature of the separator exceeds normally 80 oC (176 oF). At those temperatures so-
me 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.
Bear in mind that the viscosity groups SAE 30, 40 and 50 (SAE = Society of Automotive Engineers)
cover larger viscosity ranges and be sure to select lubricating oils with viscosities not lower than the mini-
mum values of the viscosity ranges restricted for the different separator types.

7.2 The health hazards involved when handling heavy oils and lube oils

As a result of the deterioration in quality of fuel oils, the danger has arisen that the heavy oils used on
board contain greater amounts of substances injurious to health. These include:
- polycyclic aromatic hydrocarbons,
- lead compounds,
- chemical residues.
An increased amount of polycyclic aromatic hydrocarbons is also present in used lube oils (waste oils).
The health hazards for the engine room staff depend to a large extent
• on the concentrations of the dangerous substances,
• the ambient air (inhalation of oil vapours/oil mist),
• the intensity and duration of the contact with the skin or mucous membrane.

Possible short-term effects:

• headaches,
• dizziness,
• nausea,
• itching or burning of the skin,

Possible long-term effects:

• allergic reactions, especially skin allergies,
• festering inflammation of the skin pores (oil-acne),
• damage to the central nervous system after inhalation over a long period,
• skin cancer caused by direct skin contact over a long period,
• Lung cancer or cancer of the digestive organs after inhalation over a long period
(not certain as the causes are difficult to separate from the effects of smoking and alcohol).

7.2.1 Code of practice and personal protective measures

• Avoid skin contact with heavy oils or lube oils if possible!

- Wear suitable protective gloves.
- Apply a protective ointment to the skin (e.g. ointment no. 76), especially if no protective gloves are
worn!
• Avoid breathing in oil vapours if possible!
• If possible, improve the air circulation in the room!
Fully open the air regulation flaps in the outlets of the air supply ducts in the centrifuge and filter area.
• Wash affected areas of skin frequently and thoroughly!
Apply protective ointment to the skin!
• Personal hygiene is of the utmost importance!
• Change dirty overalls regularly!
• Exercise special care when carrying out maintenance work on and cleaning heavy oil and lube oil cen-
trifuges and filters!
