1.0 Introduction The 3SEP OWS is an oily bilge water separation system designed to separate free/emulsified oil from the bilge water and check that the oil residues in the treated water do not exceed 15ppm before discharge overboard. The 3SEP OWS complies with IMO Resolution MEPC 107(49). According to MARPOL 73/78 all vessels above 400 DWT require an approved bilge water separator and alarm. The treated water released by the 3SEP OWS contains not more than 15-ppm oil in water. The system has been designed to meet the requirements prescribed by IMO MEPC 107 (49). For bilges with heavily emulsified oil in the bilge water a 3SEP OWS coupled to a JOWA EBU (Emulsion Breaking Unit) offers the best solution and ensures treated water under 5ppm. The 3SEP OWS is supplied standard with the necessary inlet for connecting a JOWA EBU. For additional information about the EBU system contact JOWA.
1.1 General

1.2 System overview , normal flow and oil release through the OWS
(See flow diagram)
The 3SEP OWS is designed for a continuous flow with automatic operation, the system does not require any chemicals. The following text gives an overview of the 3SEP OWS separation process and the 3SEP OWS general arrangement. In the first stage, tank T1, oil release is controlled by an oil sensor, CT03. The sensitivity of the oil sensor CT03 is operator adjustable in order to minimise the amount of treatable water released from T1 to the sludge tank. To adjust the sensitivity of the oil sensor CT03 see chapter 5.3 and 5.6. In the second stage emulsified oil is removed in the two filter tanks and the ppm value is monitored continuously by an oil content meter before the treated water is discharged overboard. The pneumatically controlled valves V02 and V03 release the free oil at the top of T2 and T3 to the concentrated sludge tank. Oil is released from V02 every five minutes, for a time period of 20 seconds (adjustable). Oil is released from V03 every hour for a fixed period of 5 seconds. When the JOWA 3SEP OWS is started an automatic oil release from V02, and V03 occurs for a fixed period of 3 seconds. This ensures that the pure oil that has gathered at the tops of the tanks while the unit has been in stand by mode is now released. When a 15 ppm alarm occurs, the 3SEP OWS will automatically close the overboard line V04 and open re-circulate valve V05. When the contamination falls below 15 ppm the valve for re-circulate valve V05 close and valve for overboard line V04 will open automatic. The recirculation cycle occurs for 5 minutes and is adjustable (See Chapter 5.3.3). If the treated water remains above 15ppm at the resumption of normal flow after the recirculation cycle, the 3SEP OWS will stop and an alarm will occur. The 3SEP OWS can be back flushed and restarted. See Chapter 6.1 for back flushing instructions. The system is designed as a compact skid assembly with all connection points collected, for easy “Plug n’ Play” installation. When the unit reaches the customer the only remaining thing to do is to connect water inlets/outlets, the electrical power supply and air connection, facilitating quick and easy installation onboard. Before leaving our workshop each unit has to pass a quality-test, where all functions are tested and checked. All equipment has the highest quality; the tanks are made of acid proof stainless steel, AISI 316L. Our pumps are supplied by internationally recognised brands. Spare parts are easily available from one of our offices or representatives worldwide.

3.8.1 Filling the tanks T2, T3 with filter media NOTE! Before filling check that the internal strainers are carefully fastened. Fill the tanks T2 and T3 through the upper hatches to 60-70 % of the tank volume, approximately 10-15 centimetres below the upper strainers. When the tanks are filled with filter media mount the upper hatches and back flush each filter one by one until clean fresh water is coming through the sample valves V18 and V19 (See Chapter 6.1 for detailed back flushing instructions). We recommend back flushing with fresh water at a pressure of no more than 4 bar. Maintain low water pressure and speed during back flushing to avoid losing filter media from V30. Throttle V15 and V16 to about 30%open to control water speed and pressure during back flushing.
3.9 Initial start-up checklist
Use the following start-up checklist after installation or service. Fill tank T2 and T3 with filter media Make sure the bilge pump is filled with water before start, to prevent
running dry. Check that the manual valve positions on the 3SEP OWS are correct for
normal operation (See System function chapter 4) Open all valves between the bilge water tank and the separator. Open all valves on the separator discharge line.
Back flush filter tanks 2 and 3 for a short while.(See Maintenance Chapter 6).
Turn the power on at switch S1. Check rotation of the pump Now the separator is ready for normal operation.

4.0 System Function. This chapter provides a detailed description of the unique functions of the 3SEP OWS. The material provided in this chapter gives the operator the possibility to gain an good understanding into how and why the 3SEP OWS performs its functions. It is intended that the information in this chapter may be used to help the operator optimise the 3SEP OWS performance to his or her specific bilge requirements.
4.1 Manual shut-off valve positions
The following tables indicate which of the manually controlled valves are open and closed during normal operation of the 3SEP OWS.
4.2 High level start switch/ Low Level stop switch
Automatically starts the 3SEP OWS when the bilge water level is high and stop the OWS when bilge water level is low, using level switches located in the bilge tank. (the OWS need to be in AUTO mode)
4.3 Low Level switch only.
In some installations there are only a low level switch installed in the bilge tank. To control the OWS by this switch please connect it to the terminals for low level switch and make a jumper on terminals for high level switch. The OWS will now start when the low level switch is high and stop when the low level switch is low. (the OWS need to be in AUTO mode)
4.4 Dry running protection
Protects the 3SEP OWS pump from running dry. (see electrical drawings)
4.5 Prime water

4.4.0 Optional features on the 3SEP OWS. The following are optional features for the 3SEP OWS:
4.4.1 Bilge clean mode (optional) In bilge clean mode the flow from the bilge only passes through the first stage tank T1 and then returns to the bilge tanks. The bilge water is pumped into the top of T1 thru valve V10 where most of the free oil is gathered on the coalescence surfaces. When the oil senor CT03 detects oil it is released through the pneumatically controlled valve V01 and is delivered to the concentrated sludge tank. The flow then passes through V13 and returns to the bilge.
4.4.2 Transfer mode (optional)
Some vessels have more than one bilge tank. Transfer mode uses the OWS bilge pump to transfer water between these different bilge tanks without flow passing through the 3SEP.
4.4.3 Level switches in 2 bilge tanks (optional)
It is possible to control level switches in more than 1 bilge tank. If this option is at the OWS, a switch for tank selection is mounted. With this switch it is possible to run the OWS in Auto from 2 tanks. Standard delivery is 1 tank.

4.4.4 3SEP OWS with JOWA Emulsion Breaking Unit EBU (Optional)
A JOWA EBU system may be coupled to the 3SEP OWS as an extra pree-treatment stage. The JOWA EBU & 3SEP OWS package can achieve treated water with in 5ppm. It is strongly recommended that the operator consider a 3SEP OWS coupled with JOWA EBU if the bilge water contains high levels of emulsified oil. The JOWA EBU is a chemical treatment of the emulsified oil in water. The chemical is a flocculent that helps the small particles of oil coalesce together and thus separate by gravity. The 3SEP OWS skid is ready supplied with the connection for a JOWA EBU (See Flow Diagram).

5.4 The oil content meter The oil content meter is located on the control cabinet stand on the 3SEP OWS skid. The oil content meter door displays the oil content in PPM in the water being discharged from the 3SEP OWS. The alarm limit for the oil content is adjustable between 0 - 15 PPM. The oil content in the water is measured by the sensor unit at the oil meter. Technical and Operation manual for the Oil Content meter will be delivered separate..
5.5 The pneumatic solenoid control valves
The pneumatic solenoid control valves control the valves V01 to V05. Each pneumatic solenoid control valve is marked with the valve position number. The air pressure to the solenoid control valves must be 4-6 BAR dry instrument air to get a proper function and performance of the valves.
5.6 Oil sensor CT03
The oil sensor, CT03, measures the capacitance between the sensor rod and the pipe wall. The index of the oil sensor varies from 2 to 100, where 2 is air and 100 is clean water (oil has a value of 2-20). The factory set point value is 80. The set point of CT03 may be adjusted by the operator to suit the amount of free oil in the bilge water. For example a lower set point value on CT03 may suit a bilge with high amounts of free oil. Lowering the set point value has the advantage of decreasing the amount of water released to the concentrated sludge tank. However lowering the value may also shorten the lifespan of the JOWA F – 200 C filter media, as it must absorb more oil. Conversely, raising the value will result in more water being released to the concentrated sludge tank but a longer filter media lifespan. The sensor rod has to be cleaned regularly to ensure its correct function, See chapter 6 for cleaning instructions.

6.0 Maintenance This chapter provides detailed instructions for common maintenance operations on the 3SEP OWS. A regular maintenance timetable is also included. The timetable is designed to aid the operator in scheduling minor periodic maintenance tasks thus avoiding unnecessary breakdowns.
6.1 Back flushing procedure for filter tanks T2, T3. • After JOWA F - 200 C is installed at start-up • The oil content meter gives an alarm indicating an oil content exceeding 15
ppm for a period of extended time. • After changing the JOWA F - 200 C filter media as part of regular service, • After every operation of the OWS. Proceed as follows: 1. Switch off the unit, close the valve V10 (and V11 if 3SEP OWS is connected
to a JOWA EBU). 2. Make sure that the pressurised fresh water is available at the valve V12 3. Start the back flushing of filter tank T2 by opening the valve V12 carefully. 4. Open the 3-way valve V30 so the handle is pointing against T2. Open V15
Do not fully open V15, open it slowly, and only 30% This avoids flushing away the JOWA F - 200 C filter media trough the valve V30. It also avoids damage to the pneumatic and non-return valves from flushing the JOWA F - 200 C filter media into them.
5. Be sure that V30 is allowing the flow to pass thru T2. You may check this by observing the outlet pressure at V18
6. Check the water quality through the valve V18. 7. Back flush until the water is clean. 8. Close the valves V15 ,V18 and V30 9. Start the back flushing of filter tank T3 by opening the 3-way valve V30 so

6.2 Changing JOWA F - 200 C filter media in filter tanks T2, T3. The filter media must be changed when back flushing is not cleaning the filters sufficient to get the reading in the oil meter below 15ppm. This section describes the procedure for changing the filter media.
6.2.1 Removing the filter media
NOTE! When removing filter media, make sure that you do not damage internal filter tank strainers. The strainers are located in the top and bottom of T2 and T3, see mechanical drawings. • Stop the 3SEP OWS at the main control box, close V10 (and V11 if 3SEP
OWS is connected to a JOWA EBU). • Open the filter tanks bottom valves V15, V16 and V14 to drain the water from
the filter tanks. • Open the sample valves V18 and V19 to let air into the top of the tanks. • Remove the upper hatches and wait until the water flow at the bottom has
stopped. • Open the lower hatches and empty the tanks of filter media. Clean the tanks carefully inside and check that the internal strainers are undamaged and free of carbon and oil. Check the zinc anodes and change them if more than 70 % of the zinc has corroded.
6.2.2 Filling the tanks T2, T3 with filter media
NOTE! Before filling check that the internal strainers are carefully fastened and undamaged. Should the strainers be damaged replace them. See Spare/Consumables Parts List. Fill the tanks T2 and T3 through the upper hatches to 60-70 % of the tank volume, approximately 10 centimetres below the upper strainers. When the tanks are filled with filter media mount the upper hatches and back flush each filter one by one until clean fresh water is coming through the sample valves V18 and V19 (See the previous section of this chapter for detailed back flushing instructions). NOTE! For guaranteed function we recommend the JOWA F - 200 C filter media.

Installation, Operation & Maintenance Instructions
Section 1, Page 1Issued - December 2001
INSTALLATION
1.1 INSTALLATION AND SAFETYRECOMMENDATIONS
In common with other items of process plant a pumpmust be installed correctly to ensure satisfactory andsafe operation. The pump must also be maintainedto a suitable standard. Following theserecommendations will ensure that the safety ofpersonnel and satisfactory operation of the pump isachieved.
1.2.1. GENERAL
When handling harmful or objectionable materials,adequate ventilation must be provided in order todisperse dangerous concentrations of vapours. It isrecommended that wherever possible, Mono pumpsshould be installed with provision for adequatelighting, thus ensuring that effective maintenancecan be carried out in satisfactory conditions. Withcertain product materials, a hosing down facility withadequate draining will simplify maintenance andprolong the life of pump components.
1.2.2. SYSTEM DESIGN & INSTALLATION
At the system design stage, consideration must begiven to provision of filler plugs, and the installationof non-return and/or isolating valves. The pumpsmust also be protected by suitable devices againstover pressure and dry running.
i. HORIZONTAL MOUNTING
All ranges excluding P Range Mono pumps arenormally installed in a horizontal position withbaseplates mounted on a flat surface, grouted inand bolted, thus ensuring firm fixing and a reductionin noise and vibration.
The unit should be checked after bolting down toensure that the alignment of the pump to its primemover is correct.
ii. VERTICAL MOUNTING
P Range Pumps Only
The P range pumps are intended for verticalinstallation. Care must be taken when lifting thepump into the vertical position. Normally ‘P’ rangepumps will be designed with a sole plate that will bebolted to the customers framework.
If the pump is to be mounted in any way other thandescribed above, confirmation of the installationmust be agreed with Mono Pumps Limited. All thepipework should be independently supported.
1.3.1 HANDLING
During installation and maintenance, attention mustbe paid to the safe handling of all items. Where apump or its components weigh in excess of 20 kg(45lb) it is recommended that suitable lifting tackleshould be used to ensure that personal injury ordamage to components does not occur.
For safe handling of both bareshaft pumps andpump units (pump/ gearbox/motor etc.) slings shouldbe used. The position of the slings will depend uponthe specific pump/unit construction and should becarried out by personnel with the relevantexperience to ensure that the pump is not damagedand injury to personnel does not occur.
If eyebolts do exist then these should only be usedfor lifting the individual components for which theyare supplied.
1.3.2 STORAGE
SHORT TERM STORAGE
Where a pump has to be stored for 6 months orless then the following steps are advised:-
1. Store pump inside wherever possible or if this is notfeasible then provide protective covering. Do notallow moisture to collect around the pump.
2. Remove the drain plug, if fitted. Any inspectionplates fitted should also be removed to ensure thatthe suction housing can drain and dry completely.
3. Loosen the packed gland and inject sufficient greaseinto the stuffing box. Tighten the gland nut handtight. If a water flush system is to be used do notgrease, a small amount of light oil is recommendedfor these.
4. See Manufacturers Instructions formotor/gearbox/drive instructions for storageprocedures.
Installation, Operation & Maintenance Instructions
Section 1, Page 2Issued - December 2001
LONG TERM STORAGE
If the pump is to be kept in storage for more than sixmonths then in addition to the above the followingprocedures should be carried out regularly (every 2 -3 weeks if possible):
1. If practicable rotate the pump at least three quartersof one revolution to avoid the rotor setting in thestator.
2. Note, however, that the pump is not to be rotated formore than two revolutions each time becausedamage could be caused to the rotor/ statorelements.
IMMEDIATELY PRIOR TO INSTALLATION ANDSTARTING
Before installing the pump please ensure that allplugs and inspection plates are replaced andthat excess grease/oil is removed from thestuffing box.
1.4 ELECTRICAL
Electrical connection should only be made usingequipment suitable for both rating and environment.Where any doubts exist regarding the suitability ofequipment, Mono Pumps Limited, should beconsulted before proceeding. Normally the Monopump should be installed with starting equipmentarranged to give direct on line starting.
Earthing points will be provided on electric drives (ifsupplied) and it is essential that these are correctlyconnected. When the motor is being wired andchecked for rotation, the start/stop sequence mustbe instantaneous to prevent dry running (see 2) orpressurising upstream equipment. (Check directionarrow on pump nameplate). The electricalinstallation should include appropriate isolatingequipment to ensure that the pump unit is safe towork on.
1.5 PRESSURE RELIEF VALVES AND NON-RETURNVALVES
1. It is recommended that a suitable safety device isinstalled on the discharge side of the pump toprevent over-pressurisation of the system.
2. It is also recommended that a non-return valve isinstalled on the discharge side of the pump toprevent reverse flow through the system.
When both are installed it is advised that the reliefvalve is positioned closer to the pump than the non-return valve.
IMPORTANT
The pump must never run against a closed inletor outlet valve, as this could result inmechanical failure.
1.6 GENERAL SAFETY
GREAT CARE MUST BE TAKEN TO PROTECTALL ELECTRICAL EQUIPMENT FROMSPLASHING WHEN HOSING DOWN. WHEREMONO PUMPS LIMITED HAVE SUPPLIED ABARESHAFT PUMP THE ONUS IS ON THE USERTO FIT ADEQUATE GUARDS IN COMPLIANCEWITH THE REQUIREMENTS OF THE RELEVANTREGULATIONS.
All nuts and bolts, securing flanges and basemounting fixtures must be checked for tightnessbefore operation. To eliminate vibration, the pumpmust be correctly aligned with the drive unit, and allguards must be securely fixed in position. Whencommissioning the plant, all joints in the systemmust be checked thoroughly for leakage.
If, when starting, the pump does not appear tooperate correctly (see 2), the plant must be shutdown immediately and the cause of the malfunctionestablished before operations are recommenced. Itis recommended that depending upon plant systemoperation, either a combined vacuum and pressuregauge, or a vacuum gauge only be fitted to thepump inlet port, and a pressure gauge fitted to theoutlet port, these will then continuously monitor thepump operating conditions.
1.7 DUTY CONDITIONS
Pumps should only be installed on duties for whichMono Pumps Limited have specified the materials ofconstruction, flow rates, pressure, temperature, speed etc. Where dangerous materials are to be
pumped, consideration must be given to the safedischarge from relief valves, gland drains etc.
IF THE DUTY SHOULD BE CHANGED, MONOPUMPS LIMITED SHOULD BE CONTACTED ANDTHEIR RECOMMENDATIONS SOUGHT IN THEINTEREST OF APPLICATION, SAFETY OFPLANT, EFFICIENCY AND PUMP LIFE.
Installation, Operation & Maintenance Instructions
Section 1, Page 3Issued - December 2001
2. START-UP PROCEDURE
Pumps must be filled with liquid before starting. Theinitial filling is not for priming purposes, but toprovide the necessary lubrication of the stator untilthe pump primes itself. When the pump is stopped,sufficient liquid will normally be trapped in therotor/stator assembly to provide lubrication upon re-starting.
If, however, the pump has been left standing for anappreciable time, moved to a new location, or hasbeen dismantled and re-assembled, it must berefilled with liquid and given a few turns beforestarting. The pump is normally somewhat stiff toturn by hand owing to the close rotor/stator fit.However, this stiffness disappears when the pump isrunning normally against pressure.
2.1 DRY RUNNING
NEVER RUN THE PUMP IN A DRY CONDITIONEVEN FOR A FEW REVOLUTIONS OR THESTATOR WILL BE DAMAGED IMMEDIATELY.CONTINUAL DRY RUNNING COULD PRODUCESOME HARMFUL OR DAMAGING EFFECTS.

DIRECTIONS OF ROTATION
BEFORE THE DIRECTION OF ROTATION ISCHANGED, MONO PUMPS LIMITED MUST BECONSULTED SO THAT THE SUITABILITY OFTHE PUMP CAN BE CONFIRMED WHENOPERATING ON THE NEW DUTY.
2.3.1. GLAND PACKING
Where a pump is supplied fitted with gland packing(manufactured from a non-asbestos material), thegland will require adjustment during the initialrunning in period. Under normal working conditionsa slight drip from the gland under pressure does notharm and assists in lubricating the packing. A glanddrip is, however, undesirable when handlingcorrosive, degreasing, or abrasive materials. Underthese conditions the gland must be tightened theminimum amount whilst the pump is running toensure satisfactory sealing when under pressure, orto stop entry of air when under suction conditions.
Provision of a gland drain should be considered,especially for the leakage of hazardous products.
CARE IS REQUIRED WHEN ADJUSTING THEGLAND WHILST PUMP IS RUNNING.
2.3.2 MECHANICAL SEALS - ALL PUMPS
When a mechanical seal is fitted to the pump it maybe necessary to provide a barrier fluid to some partof the seal. This should be provided in line with theseal manufacturers instructions.
2.4. GUARDS
In the interests of safety, and in accordance with theU.K. Health and Safety at Work Act 1974, all guardsmust be replaced after necessary adjustments havebeen made to the pump.
2.5 WARNING/CONTROL DEVICE
Prior to operating the pump, if any warning or controldevices are fitted these must be set in accordancewith their specific instructions.
2.6 PUMP OPERATING TEMPERATURE
The range of temperatures the pump surfaces willdevelop is dependent upon factors such as producttemperature and ambient temperature of theinstallation. There may be instances where theexternal pump surface can exceed 50oC.
In these instances, personnel must be made awareof this and suitable warnings/guarding used.
Installation, Operation & Maintenance Instructions
Section 1, Page 4Issued - December 2001
2.7 NOISE LEVELS
1. The noise sound pressure level will not exceed85dB at one metre distance from the pump.
2. This is based on a typical installation and does notnecessarily include noise from other sources or anycontribution from building reverberation.
3. For pumps identified below, the noise levels varybetween 85 and 95dB but will not exceed 95dB atone metre distance from the pump.
Pump Sizes (based on E Range PumpingElement)
Single Stage Size 12 and aboveTwo Stage Size 9 and aboveFour Stage Size 7 and aboveSix Stage Size 7 and aboveEight Stage Size 6 and above
2.8 LUBRICATION
Pumps fitted with bearings should be inspectedperiodically to see if grease replenishment isnecessary, and if so, grease should be added untilthe chambers at the ends of the bearing spacer areapproximately one third full.
Periodic bearing inspection is necessary to maintainoptimum bearing performance. The most expedienttime to inspect is during periods of regularscheduled equipment downtime - for routinemaintenance or for any other reason.
Under tropical or other arduous conditions, however,a more frequent examination may be necessary. Itis therefore advisable to establish a correctmaintenance schedule or periodic inspection.
BP LC2 / Mobilgrease XHP 222 or their equivalentmust be used for replenishment.
2.9 PUMP UNITS
Where a pump unit is dismantled and re-assembled,consideration must be given to ensure that whereappropriate the following steps are covered.
1. Correct alignment of pump/gearbox2. Use of appropriate couplings & bushes3. Use of appropriate belts & pulleys correctly
tensioned.
2.10 CLEANING PRIOR TO OPERATION
i. Non Food Use
During the commissioning of a new pump orrecommissioning of an overhauled pump, it isadvisable to clean the pump prior to the initialoperation of the pump in the process.
ii. Food Use
When a pump has been supplied for a foodapplication, it is important to ensure that the pump isclean prior to initial operation of the pump.
Therefore, it is important that a clean-in-placetreatment is executed on the pump at the followingtimes:-
1. When the pump is first commissioned for use.
2. When any spare components are fitted into thewetted area of the pump.
A recommended CIP procedure is as follows:
This procedure should not be used on the CPPump Range. Please consult our applicationengineers for a suitable procedure.
Caustic WashLQ94 ex Lever Diversey or equivalent2% concentration
Acid WashP3 Horolith 617 ex HenkelEcolab or equivalent 1% concentration
Procedure
1. Caustic wash @ 75°C for 20 mins2. Water rinse @ 80°C for 20 mins3. Acid wash @ 50°C for 20 mins4. Water rinse @ 80°C for 20 mins
• CIP flow rates (hence pumpspeeds) should be maximised to achieve highestlevel of cleanability.
Pumps fitted with CIP by pass ports will permithigher flow rates without the need to increase pumpspeed.
Installation, Operation & Maintenance Instructions
Section 1, Page 5Issued - December 2001
• The use of ‘neat active’ causticand acid chemicals is notrecommended. Proprietary cleaningagents should be used in line with manufacturersinstructions.
• All seals and gaskets should bereplaced with new if disturbedduring maintenance.
• Pump internals should be regularly inspected toensure hygienic integrity is maintained, especiallywith respect to elastomeric components and seals,and replaced if necessary.
The four stages constitute one cycle and werecommend that this cycle is used to clean the pumpbefore use on food.
Once the pump has been commissioned, thecleaning process will depend upon the application.The user must therefore ensure that their cleaningprocedures are suitable for the duty for which thepump has been purchased.
2.11 WIDETHROAT PUMPS
Specific pumps may have auger feed screws, withor without a bridge breaker system to feed thepumping element. If the pump installation requiresthat these cannot be enclosed, care must be takento ensure personnel cannot gain access whilst thepump is operating. If this is not possible anemergency stop device must be fitted nearby.
2.12 EXPLOSIVE PRODUCTS/ HAZARDOUSATMOSPHERES
In certain instances the product being pumped maywell be of a hazardous nature.
In these installations consideration must be given toprovide suitable protection and appropriate warningsto safeguard personnel and plant.
2.13 ACCESS PORTS
Where access ports are fitted then the followingsteps must be followed prior to removal:
1. Pump must be shut down and the electrical supplyisolated.
2. Protective clothing should be worn, especially if thepumped product is obnoxious.
3. Remove access plate with care utilising wherepossible drip trays to collect product leakage.
Access ports are included to assist in removingblockages and to allow a visual check on thecomponents within the suction chamber.
It is not to be considered as an additional method indismantling the pump.
Re-assembly of the plate should be completed usingnew gaskets prior to the pump being switched on.
2.14 ADJUSTABLE STATORS
If adjustable stators are fitted then the followingsteps must be followed for adjusting the clampingdevices.
The adjustable stator assembly is designed to givean even compression around the statorcircumference. It is designed to be used whenpump performance reduces through wear to anunacceptable level, to restore the required flow rate.
The stator compression is increased using thefollowing steps:-
1. Release the six locking screws half a turn.
2. Tighten the eight clamp screws until adjustmentallowed by releasing the lock screws has been takenup.
3. Repeat steps 1 and 2 until the pump performancehas been restored to its former level.
NOTE
It is imperative that when adjusting the stator thatonly sufficient pressure is placed on the stator toenable the capacity of the pump to be reinstated.
Over tightening of the stator could easily result indamage to the driver by overload and so extremecare must be taken when carrying out theseadjustments. It is therefore advisable to make theadjustment while the pump is running and powerreadings can be monitored.
REMOVAL OF ADJUSTABLE STATOR
The procedure for removal of an adjustable stator isthe same as that of a standard one, except it isnecessary to remove the clamp plates before thestator can be twisted off the rotor.
Installation, Operation & Maintenance Instructions
Section 1, Page 6Issued - December 2001
This can be done by undoing the clamp screws;then releasing the clamp plate by using the lockingscrews as jacking screws to remove the clampplates.
Re-assembly will be done using the reverseprocedure.
2.15 MAINTENANCE OF WEARING COMPONENTS
2.15.1 ROTOR AND STATOR
The wear rate on these components is dependenton many factors, such as product abrasivity, speed,pressure etc.
When pump performance has reduced to anunacceptable level one or possibly both items willneed replacing.
2.15.2 DRIVE SHAFT - PACKED GLAND
The wear rate of the gland area is dependent onmany factors such as product abrasivity and speed.Regular gland maintenance will maximise the life ofthe shaft. Replacement of both the gland packingand shaft will be necessary when shaft sealingbecomes difficult to achieve.
2.15.3 COUPLING ROD JOINTS
Regular maintenance and lubrication will maximiselife of the joints.
Replacement of one or both joint assemblies andpossibly the coupling rod may be necessary whenwear is apparent.
It is essential to replace all the joint items withgenuine Mono parts to ensure maximum life.
2.15.4 FLEXISHAFT DRIVE PUMPS
With this design there are no wearing items toreplace in the drive train, however, if during routineinspection the shaft is visibly damaged / distortedor the protective coating is damaged, then this itemshould be replaced to avoid unexpectedbreakdowns.
3.0 ASSEMBLY AND DISMANTLING
Section 4 contains the steps to dismantle andre-assemble the pump. All fastenings must betightened securely and when identified theappropriate torque figures should be used.
3.1 USE OF ITEMS NOT APPROVED ORMANUFACTURED BY MONO PUMPS LIMITED
The pump and its components have been designedto ensure that the pump will operate safely within theguidelines covered by the legislation.
As a consequence Mono Pumps Limited have declared the machine safe to use for the dutyspecified as defined by the Declaration ofIncorporation or Conformity that is issued with thisInstruction Manual.
The use of replacement items that are not approvedby or manufactured by Mono Pumps Limited mayaffect the safe operation of the pump and it maytherefore become a safety hazard to both operatorsand other equipment. In these instances theDeclaration provided will therefore become invalid.The guarantee referenced in the Terms andConditions of Sale will also be invalidated ifreplacement items are used that are not approved ormanufactured by Mono Pumps Limited.
DISPOSAL OF WORN COMPONENTS
When replacing wearing parts, please ensuredisposal of used parts is carried out in compliancewith local environmental legislation. Particular careshould be taken when disposing of lubricants.
