2.2.2 Filtering unit
The filtering unit comprises a distributor (16) in thecentre which routes the incoming oil and controls thefiltering and backflushing procedure. This is coveredby a sleeve (18) over which two types of filterelement are placed. The bottom section houses thefiner full-flow filter elements (30) and the shorter topsection houses the coarser diversion filter elements(29). Both sets of filter elements are located over thefull-flow rods (32) and diversion rods (31) tocomplete the filtering unit.
The full-flow filter elements (30) are clampedbetween the full-flow companion spacer (27) and thefull- flow cover (28) by means of the springs (38) andthe rods (32).
The diversion filter elements (29) are clampedbetween the diversion companion spacer (25) andthe diversion cover (24) by means of the rods (31).
Both types of filter element are made up from twoelement halves. Each half comprises an aluminiumframework of 12 equal sectors separated by radialribs. Between each rib is a stainless steel filterscreen. When the pairs of filter elements are stackedtogether they form 12 independent filtering columnsin each filter chamber.
The main physical differences between the twotypes of elements are as follows:
• The full-flow filter element screen is finer.
• When the two filter halves are put together thefull-flow filter elements have the openings on theoutside (A) and the diversion filter elementshave the openings on the inside (B).

2.2.3 Hydraulic motor
The hydraulic motor (45) is located on top of the filterhousing. It is driven by a small part of the filtered oil.The hydraulic motor rotates the distributor (16) in astepwise manner in one direction which controls thefiltering/backflushing procedure. The stepwiserotation of the distributor is indicated by an operatingindicator (53) fitted to the driving shaft of thehydraulic motor.
The hydraulic motor contains a piston (20) thatmoves up and down in a reciprocating motion insidea cylinder (A), (the body of the hydraulic motor). Thepiston is via driving pins (24), connected to a helicalgrooved driven ratchet (30) which converts theupward motion of the piston into a rotational step.This rotational step is transmitted via the drivingratchet (29) and driving shaft (22) to the distributor.Downward motion of the piston disengages thedriving ratchet and the distributor does not move.
Valves in the cylinder are activated by the movementof the piston, so controlling the driving oil to theupper and lower side of the piston respectively.

2.3 APPLICATIONS
The application for this type of filter is for full-flow filtering of lubricatingoils for diesel engines.
The filter is installed in the full-flow lube oil system as close to theengine as possible. Its function is to protect the engine against harmfulsolid particles, that may not yet have been removed by the centrifugalseparator, which is installed in the by-pass lube oil system.
The illustration below shows the two systems.
Note that the flow through the full-flow system (and the filter) istypically 50 - 100 times greater than the flow through the by-passsystem (and the separator).

2.4 DESIGN FEATURES
The Moatti automatic lube oil filter is not a conventional type ofautomatic filter. Conventional filters generally work on the principle thatthe backflushing is initiated when the pressure drop across the filterreaches a pre-set value. The Moatti filter is unique as it works on aprinciple of continuous backflushing. Generally 3 to 5% of the filteredoil is always backflushing one column of the filter elements and drivingof the hydraulic motor.
The main features and advantages of the unique Moatti automatic lubeoil filter are as follows:
• Continuous backflushing
• Disc-type filter elements
• Filtered oil drives the continuous backflushing
• No disposable filter elements
• Constant pressure drop over the filter
• Compact and lightweight design.
2.4.1 Continuous backflushing
The Moatti automatic filter is continuously backflushed, column bycolumn. The backflushing is performed with filtered oil and the entirefilter surface is cleaned once every 1 to 3 minutes. This preventsretained solids from sticking to the filter surface, ensuring a low andconstant pressure drop. Therefore, the need for manual cleaning of thefilter elements is reduced to a minimum. This generally allows for morethan 12 000 operating hours between manual cleaning and inspectionof the filter.
2.4.2 Disc-type filter elements
The Moatti automatic filter is fitted with robust disc-type filterelements.This design feature, together with the low and constantpressure drop (from the continuous backflushing), eliminate the risk ofcracked filter elements.
2.4.3 Filtered oil drives the continuous backflushing
Filtered oil is used for backflushing of the filter elements. Filtered oil isalso used to drive of the hydraulic motor which, in turn, drives thedistributor, so controlling the backflushing. As a result, electricity andcompressed air are not required for the operation.
FUNCTION DESCRIPTION
514-IB1-07 fd04E45.fm 11
2.4.4 No disposable filter elements
The Moatti automatic filter contains no disposable elements. Thebackflushed solids are concentrated in the secondary filtrationchamber (diversion chamber) and are discharged by periodic draining.
2.4.5 Constant pressure drop over the filter
As the continuous backflushing process gives a constant pressuredrop it is possible to get an immediate indication from the pressuredrop indicator when something is wrong in the lube oil system.
2.4.6 Compact and lightweight design
The design gives a simple compact, lightweight and reliable systemwhich is easy to install. It also provides increased possibilities for up-grading of existing installations

2.5 PRINCIPLES OF OPERATION
2.5.1 Overview
The main principle of operation for the Moatti automatic lube oil filter isas follows:
• The oil to be filtered is pumped from the lube oil sump through thefilter and to the engine.
• When the oil reaches the filter it first passes through a strainerlocated in the inlet body. This should remove any large foreignmatter like pieces of rag which may be left in the system aftermaintenance.
• Once past the strainer the oil then passes through the full-flowfilter elements (where the solids are trapped) and to the engine. Apart of the filtered oil (3 to 5 % of the capacity of the filter) is usedto backflush part of the full-flow filter elements and for drive of thehydraulic motor.
• The backflushed oil with solids from the full-flow chamber is led tothe diversion chamber where it is filtered again, before it is ledback to the lube oil sump.
• The filter elements in the diversion chamber are backflushed (withfiltered oil) in the same manner as in the full-flow chamber.
• The solids concentrated in the diversion chamber are dischargedfrom the system by periodic draining.
The whole filtering cycle can be considered as two phases:
Phase I - filtering in both chambers- backflushing in the full-flow chamber
Phase II - filtering in both chambers - backflushing in the diversion chamber

2.5.2 Phase I
Filtering in the full-flow chamber
1. Unfiltered oil enters the filter at (A) and flows through the strainer(S) into the chamber (B) - the space between the distributor (C)and the inner perimeter of the sleeve (J) on which the full-flowfilter elements (D) are mounted.
2. The oil is distributed from this space through the full-flow filterelements (D) in eleven of the twelve filtering columns (the twelfthcolumn is being backflushed). The solids are trapped on the innerside of the elements in the eleven filtering columns.
3. The filtered oil flows into the full-flow chamber (E) and is fedthrough the filter outlet (F) to the engine.
4. A few hundred litres per hour of the filtered oil are routed from thefull-flow chamber (E) through the feed pipe (G) to the hydraulicmotor (H) to drive the distributor (C).
Backflushing in the full-flow chamber
5. While the full-flow takes place in eleven columns, solids are beingremoved from the elements in the twelfth column by backflushing(from outside to inside of the column) using part of the filtered oilfrom the full-flow chamber (E).
6. The backflushed oil and removed solids flow through passage (K)in the distributor (C) to the diversion chamber (L).

Filtering in the diversion chamber
7. The backflushed oil with solids that enter the diversion chamber(L) passes through ten of the diversion filtering columns (fromoutside to inside). The solids are trapped on the outside of thediversion filter elements (M).
8. The filtered backflushed oil flows through the return passage (N)in the distributor and is recirculated to the lube oil sump from thebackflushed oil outlet (P).
9. No backflushing is performed in the diversion chamber during thisphase of the operation.

Backflushing in the diversion chamber
3. Part of the filtered oil in the full-flow chamber (E) flows through thedistributor passage (R) and through one column of the diversionfilter element (M), from inside to outside, removing the trappedsolids from the outer side of the elements.
4. The heavy particles settle to the bottom of the diversion chamber(L) and are discharged periodically through the drain valve (V).
Filtering in the diversion chamber
5. The backflushed oil, without the settled solids, now passesthrough the other eleven columns, from outside to inside, of thediversion filter elements. The solids are trapped on the outer sideof the elements.
6. The filtered oil flows through the return passage (N) in thedistributor and is recirculated to the lube oil sump from thebackflushed oil outlet (P).
Removal of trapped solids
7. The solids trapped in the diversion chamber (settled solids andsolids from the elements) are discharged periodically through thevalve (V).

2.6 PRESSURE DROP INDICATOR
The inlet pressure P1 is taken before the strainer (15) in the inlet body(2) and the outlet pressure P2 is taken on the outlet body (3). Bothmonitoring points are fitted with isolator cocks and pipework toconnect them to the pressure drop indicator (44).
The pressure drop indicator shows the pressure drop ∆P (P1 - P2)across the full-flow elements. Due to the continuous backflushing, ∆Pis constant during operation. It may vary from 0.2 to 0.5 bar dependingon the installation and filter size.
If for any reason the filter starts to clog, the pressure drop willincrease. To prevent the filter becoming completely clogged thepressure drop indicator is equipped with a preset alarm value (∆P-alarm). This value generally ranges from 0.8 to 1.0 bar and is set atthe factory.
If the pressure drop reaches the preset value, an electrical contact isswitched giving possibility for a signal to the control system of theengine.
CAUTION:
The pressure drop indicator must be connectedto the engine control system for the ∆P-alarm tosafeguard the engine. On activation of a ∆P-alarm, the trouble shooting activities must bestarted immediately, see chapter 4.

3.1 PRE-START CHECKS
The operation of the Moatti automatic lube oil filter is simple and theoperator has only to make checks before initial start-up, at initial start-up and during operation.
3.1.1 Before initial start-up
CAUTION:
The lube oil system must be cleaned fromcontaminants from the installation work beforethe first operation of the automatic filter. This“flushing” must NOT be made through theautomatic filter as it can damage the filterscreen and clog the filter, see chapter 6.
CAUTION:
Ensure that the pressure drop indicator isconnected to the control system of the engine.
3.1.2 Immediately before the initial start-up
!
!
The following checks must be made.
1. Check that the following valves and cocks areopen:
• Inlet valve V1 to the filter
• Outlet valve V2 from the filter
• Outlet valve V3 in the return to sump(backflushing) line (if fitted).
• Isolator cocks (A) and (B) on thepressure drop indicator pipes, located onthe inlet (2) and outlet (3) bodyrespectivelly.

3.2 INITIAL START-UP
CAUTION:
Ensure that the other items of equipment in theengine lube oil system are fully functional andoperational.
The following describes the checking procedures for the initial start-up.
1. Ensure that lube oil is flowing through the filter at the requiredcapacity.
2. Check the function of the hydraulic motor. Make a note of thenumber of minutes it takes for the operating indicator (53) to doone revolution.
The following times are given as a guide for a normal operatingcondition .
• Engine at standstill (pre-lubrication): 10 minutes maximum• Working engine: 5 minutes maximum
NOTE !
If the operating indicator does not rotate or the time forone revolution is more than the respective 10 or 5minutes, see chapter 4 "Trouble Shooting".
3. Check the pressure drop on the pressure drop indicator and readoff the value. Under normal operating conditions the value shouldnot exceed 0.4 - 0.5 bar. If the value is higher see chapter 4.
4. Check for any external oil leaks. If there is an oil leakage, tightenthe bolts or change the gaskets as necessary, see also chapter 4.

3.3 NORMAL OPERATION
When correctly installed and initially started-up the Moatti automaticlube oil filter requires very little attention. However, to ensurecontinued reliable operation, the filter must be checked at regularintervals.
3.3.1 Determination of reference values
Approximately 100 operating hours after the initial start- up or majormaintenance procedure, (see chapter 5), reference values for thepressure drop and rotation of the operating indicator must be noted asfollows:
1. Note the pressure drop on the pressure drop indicator and markthis value "∆P-ref" on the indicator.
2. Note the number of minutes for one revolution of the operatingindicator.
3.3.2 Daily checks
Every day the pressure drop and operating indicator must be checked,visually for:
1. The pressure drop does not exceed 0.2 bar higher than thereference value determined in 3.3.1 (1).
2. The operating indicator rotates in a stepwise manner.
3. The number of minutes for one revolution is not more than 1minute above the reference value determined in 3.3.1 (2).
If the pressure drop and operating indicator values are higher thanstated see chapter 4, "Trouble Shooting".

3.3.3 150-200 operating hours checks
The diversion chamber must be drained after every 150-200 operatinghours. The procedure to do this is as follows:
1. Unlock the drain cock (46) by loosening the lock screw and nut.
WARNlNG:
Open the drain cock slowly to prevent hot oilfrom splashing in the funnel.
2. Open the cock by 1/4 of a turn (cock handle in line with cock) andkeep it open for approximately 15 seconds. The drained lube oilquantity will be approximately 15 litres and will drain into a sludgetank.
3. Close the cock and lock it, (tighten lock screw and nut).
3.3.4 12000 operating hours checks
Cleaning and inspection of the automatic filter must be carried out inaccordance with the maintenance procedures in chapter 5 after every12000 operating hours.
3.3.5 Alarm checks

3.4 SHUTDOWN PROCEDURES
There are no special procedures to carry out whenthe filter is shut down. Its operation is entirelydependent on the lube oil pump. When the lube oilpump is switched off or stops the valves on the filtermay be left open.
CAUTION:
Always check that the valvesare open before re-starting assomebody may have closedthem.
3.5 EMERGENCY OPERATION
If the hydraulic motor is not working properly, anemergency operation can be used to manuallybackflush the filter. This procedure should only beused when the following have been checked :
1. Valve (V3) in the return to sump line (if fitted)has not been closed by mistake.
2. Gaskets for the hydraulic motor are not available(See chapter 7)
3. A replacement hydraulic motor is not available.
The emergency backflushing procedure for the filtercan be performed by turning the operating indicator,using a spanner, from time to time, (based uponexperience),until repair/replacement can be made.
CAUTION
If it is not possible to turn theoperating indicator by handduring operation, do not use apipe on the end of theoperating indicator. Failure toobserve this may result indamage to the equipment.

4.1 GENERAL
This chapter deals with the most common problemswhen the filter does not work correctly or when the∆P- alarm occurs. It will give the possible reasons forthe problems and actions to solve them.
The chapter is divided into the following main parts:
• Problems at initial start-up before ∆P-alarmoccurs, see section 4.2.
• External leakage, see section 4.3.
• Abnormal values on daily checks but no ∆P-alarm, see section 4.4.
• Problems with the ∆P-alarm activated, seesection 4.5.

4.2 PROBLEMS AT INITIAL START-UP BEFORE A ∆P-ALARM OCCURS
4.2.1 No revolution of the operating indicator(Item 53)
CAUSE ACTION
1. Valves V1, V2 and/or V3 are closed. Open the valves slowly and completely (V2 before V1). Pay special attention to valve V3 in the “return to sump” line because its location may not be near the filter.
2. Lube oil temperature too low. Wait and see because the temperature will probably increase. If it does not, check the lube oil cooling system.
3. Lube oil pressure too low. Probably the engine is by-passed or only a small pre-lube oil pump is in operation.If so, connect the engine and main pump.
4. The hydraulic motor is not working properly (i) Manually turn the operating indicator (53).
(ii) Inspect the hydraulic motor, see chapter 5
If necessary :
(iii) Replace the hydraulic motor.
5. The “return to sump” line is too long and narrow.
Modify the installation. The return line should be of equal or greater diameter than the outlet and should be a short pipe with a mini-mum number of bends and no restrictions.

4.4 ABNORMAL VALUES ON DAILY CHECKS BUT NO ∆P-ALARM
4.4.1 Pressure drop value is more than 0.2 bar higher than the reference value from section 3.3.1.
CAUSE ACTION
1. The concentration of contaminants in the oil feed is too high causing partly clogged filter elements and/or inlet stainer. This could be due to :
(i) Rough weather stirs up the contami-nants from the bottom of the sump (for ships only)
(ii) The centrifugal separator is out of operation
(iii) Engine problems (like piston seizure) occur suddenly
(iv) A large amount of new oil has been added to the system, which has “taken up” contaminants from the sump walls.
Drain the diversion chamber more frequently. Carry out the “drain and turn” action from time to time, see below.
Ask the operator to ensure that the centrifugal separator is put into operation and to check the condition of the engine.
2. There is a normal concentration of conta-minants in the oil feed. However, the times between draining the diversion chamber may be too long causing partly clogged filter elements.

4.5.1 Alarm during initial start-up
a) "Drain and turn" action reduces ∆P to below alarm setting.
b) “Drain and turn" action does not reduce ∆P to below alarm setting.
Note: Probable reason for clogging of the filter elements and/or inlet strainer is that the lube oilsystem before the initial start-up has been flushed through the filter.
CAUSE ACTION
1. Partly clogged filter elements. Probably due to lube oil system being flushed through the filter before the initial start-up.
Continue the operation of the filter but check every few minutes and repeat “drain and turn” action if necessary.
CAUSE ACTION
1. Filtration temperature too low Wait and see because the temperature will probably increase. If it does not, check the lube oil cooling system.
2. Clogged inlet strainer Drain the full-flow chamber, see chapter 5, and open the inspection covers (92).
• If the strainer is clogged by foreign matter, remove it, close the inspection covers and continue the operation.
• If the strainer is clogged by foreign matter and it cannot be removed, close the inspection covers and open the filter and clean the strainer, see chapter 5.
• If the strainer is not clogged continue with item 3 below.

b) “Drain and turn" action does not reduce ∆P to below alarm setting.
CAUSE ACTION
1. Partly clogged filter elements. Continue the operation of the filter but be prepared for the alarm to return, see below.
CAUSE ACTION
1. If the operating indicator takes more than 3-5 minutes to complete one revolution, then the backflushing efficiency is reduced causing clogged filter elements. The reason for the alarm could be :
(i) A valve (V3) in the “return to sump” line has been partially closed by mistake. If the valve has been closed there will not be any revolution.
(ii) The “return to sump” line is too long and narrow.
Open the filter and clean the elements, see chapter 5.
Open the valve, (V3).
Modify the installation. The return line should be of equal or greater diameter than the outlet and should be a short pipe with a minimum number of bends and no restrictions.
2. If the revolution time is shorter than that stated in item (b) 1, reason for the alarm could be :
(i) The centrifugal separator is incorrectly adjusted or too small.

(ii) The centrifugal separator is out of operation.
(iii) Engine problems (like piston seizure) occur suddenly.
(iv) A large amount of new oil has been added to the system, which has “taken up” contaminants from the sump walls.
Shorten the time between draining and continue operation but check regularly. Carry out the “drain and turn” action from time to time. Ask the operator to ensure that the centrifugal separator is put into operation if possible and to check the condition of engine.
2. There is a normal concentration of contaminants in the oil feed. However, the times between draining of the diversion chamber may be too long causing partly clogged filter elements.
Drain the diversion chamber more frequently.
3. It seems that the hydraulic motor is not working properly. The criteria for “not working properly” is that the time for one revolution of the operating indicator is more than 3-5 minutes.
Check that a valve (V3) in the “return to sump” line has not been closed by mistake. If the valve was closed, open it. The hydraulic motor should then work normally. However, if it still does not work, be prepared to overhaul the hydraulic motor soon, see chapter 5.

5.1 GENERAL
The design and the operating cycle of the filterminimize the need for maintenance. However inorder to ensure reliable operation of the filter it hasto be
cleaned and inspected every 12000 operating hours (1,5 - 2 years).
Pressure drop alarms or breakdowns (see chapter4) may shorten this period. This chapter is dividedinto the following sections :
• Overhaul of the filter (5.2)
• Overhaul of the hydraulic motor (5.3)
• After maintenance checks (5.4)
Sections 5.2 and 5.3 are structured as follows :
• Tools and spares required
• Disassembly procedures
• Cleaning/inspection tasks
• Assembly procedures
Section 5.4 covers the checks that must be madebefore the filter is put back into service. Requirednew parts can be found in chapter 7, which containsan illustrated parts list for the filter and hydraulicmotor. A sample ordering form is included in theappendices for ordering spare parts.

5.4.2 Checks at start-up
1. Check the filter for external oil leaks, (seechapter 4 Trouble Shooting for solutions).
2. Check the pressure drop on the pressure dropindicator. It should not be higher than thereference value noted in section 3.3.1.
If the pressure drop is higher the filter elementsmay not have been cleaned properly. Thesolution is:
(i) Clean them again now
(ii) Accept that the next maintenance could bemuch sooner.
Note that during this check the temperature ofthe oil to the filter must be at normal operatinglevel.
3. Check the rotation of the operating indicator(53). One revolution should not take longer thanthe reference value noted in section 3.3.1.
Check that the oil inlet temperature is normaland that the engine is operating at normal load.If one revolution still takes considerably longerthan the reference value, the hydraulic motorhas been assembled incorrectly. See section 5.3about how to check the assembly.

6.2 THE FILTER IN THE SYSTEM
6.2.1 Marine propulsion and power station engines
Specification
The filter should be installed in the main lube oil system in accordancewith the diagram below.
Filter location in a main lube oil system
A = Trunk Piston Diesel Engine
B = Lube Oil Sump
C = Duty Lube Oil Pump
D = Stand-by Lube Oil Pump/Pre-Lube Pump
E = Cooler
F = Moatti Automatic Lube Oil Filter
Recommendation
It is recommended that the filter is installed after the lube oil coolerwithin the main lube oil system. This means that sudden pressureincreases from the starting of the stand-by lube oil pump will be"damped" in the cooler eliminating possible filter problems.
