PRECAUTIONSAlways wear protective clothing, face shield, safetyglasses and gloves when working on or near yourmetering pump.All LMI pumps are shipped from factory with waterin pump head to make easier priming.If the pump head is empty, refill it with water orsolution compatible with pumped solution beforestarting up the pump (see note on the Liquid EndSheet).Solution compatibilityVerify that the liquid handling components arecompatible with the pumped solution (refer to LiquidEnd Sheet).Make certain that all tubing is securely attached tofittings prior to start-up.Tubing supplied allows to match with pumpmaximum specifications.All fittings should be hand tightened.Overtighteningor use of a pipe wrench can cause damage to thefittings, causing the pump to lose prime or notfunction.All LMI pumps have straight ¾’’- 16N or 7/8 ’’- 14Nor 1"- 12 N machine threads on the head andfittings.The seal rings prevent leaks. Do not use Teflon tapebetween fittings and pump head.LMI, Doseur à membrane, L001, Rev.B, 1098

PART II – INSTALLATIONII – 1. HYDRAULIC INSTALLATIONThe pump can be mounted in one of two ways :• Flooded suction (ideal installation).• Suction lift – when suction lift is less than 1,5 m forsolutions having a specific gravity of water. YourLMI metering pump must be mounted so that thesuction and discharge valves are vertical.Flooded suctionThe pump is mounted at the base of the storage tank.This installation is the most trouble-free, and isrecommended for very low outputs, solutions thatgasify, and high viscosity solutions. (Install shut offvalve on the tank).1 Solution tank 9 Vent4 Pump 10 Tee8 Injection check valveFig. 2.1a : Flooded suctionSuction lift• Wall bracket mount. The pumpmay be mounted directly above thesolution tank. A pump mounted inthis manner allows for easychanging of solution tank.1 Solution tank4 Pump6 Pressure line8 Injection check valve10 TeeA 50 mm space forsediment accumulationII - 1Fig. 2.1b : Suction liftLMI, Doseur à membrane, L001, Rev.B, 1098

Pump locationLocate pump in an area convenient to solution tank andelectrical supply.The pump should not be subjected to ambienttemperatures above 50°C. Avoid exposing to directsunlight the pump.Tubing connections• For installation and trouble-free running, use onlyrecommended tubing size (refer to spare parts list).• Do not use clear vinyl tubing on the discharge sideof the pump. The pressure created by the pump canrupture the vinyl tubing.• Before installation, all tubing must be cut with aclean square end.• Remove the plugs which protect the headconnections and valves.• Do not use pliers or pipe wrench on coupling nuts orfittings.• When tubing connection fits on a cone, dip end inhot water.Refer also to the Liquid End Sheet.Foot valve/Ceramic weightThe foot valve must be sit in a vertical position at thebottom.Position approximately 50 mm off the bottom if the tankor drum contains sediment.The ceramic weight positions the foot valve in a verticalposition.Refer to the Liquid End Sheet for details of connections.1 Solution tank 4 Pump2 Foot valve 11 Ceramic weightFig. 2.2a : Foot valve/Ceramic weightInjection check valveCanne d’injectionConnect the injection check valve to your discharge(outlet) line (refer to the Liquid End Sheet).For in-line injection, use fitting or pipe tee with reducingbushing to ½’’ (12x17).Use Teflon tape or pipe dope to seal the pipe threadsonly.When installing the injection check valve, be sure toposition it so that the valve enters the botton of yourpipe in a vertical position (see fig. 2.2b).Variations left and right within 30° are acceptable.For low pressure (under 1,7 bar) or open tank use, theinjection nozzle prevents siphoning but not flowincrease.In this case,we recommend the use of a 4-Functionvalve.Refer to the Liquid End Sheet for details of connections.II - 3LMI, Doseur à membrane, L001, Rev.B, 1098

8 Injection check valve B Use Teflon tape10 Tee C Do not use Teflon tape12 Reducing bushing ½ ‘’ D ± 30° variation acceptable13 Pipe cross sectionFig. 2.2b : Injection check valveII – 2. ELECTRICAL INSTALLATIONCheck the specifications of the pump and comparethem with the voltage available on your installationbefore making connections.WARNING :To reduce the risk of electrical shock, the meteringpump must be plugged into a fused grounded outletwith ratings conforming to the pump specification chart(see Technical characteristics : refer to peak power todetermine the appropriate fuse size).DO NOT USE ADAPTERS.All wiring must be conform to local electrical codes.OVER-VOLTAGELMI pumps include a Varistor vonnected on the supplyvoltage terminals.This device is an over-voltage protection. It will burn ifthe supply voltage exceeds 150 V for 115 V ratedpumps or 275 V for 230 V rated pumps to protect thepulser.As soon as it happends, it means the pump got a toohigh voltage peak. After supply voltage control, replacethe Varistor and the pump will run again.II - 4LMI, Doseur à membrane, L001, Rev.B, 1098

PART III – START UPPumps are shipped from the factory with water in thepump head to aid in priming. After a long storage, refillthe pump head with water or solution compatible withpumped solution (see note on the Liquid End Sheet).7. The volume and the time unit are known. Calculatethe output. If the output is too low or too great, adjustspeed and or stroke, estimating required correction.8. Adjust stroke length knob to desired value refering tocalibration.III – 1. PRIMINGAfter connecting the pump, plug in or switch the pumpon. While the pump is running, set the speed knob at80% and the stroke knob at 100%. If the pump isequipped with a pressure control knob (B7, C7), set theswitch on « INTERNAL » and turn the pressure controlknob fully clockwise.III – 2. OUTPUT ADJUSTMENTCONTROLSOnce the pump has been primed, an appropriate outputadjustment must be made.The identification plate indicates the output at max.stroke and max. speed (100%) and max. pressure. Thegraduations of stroke knob and speed knob correspondto percentage of this max. output.Note : P0 pumps have no stroke adjustment.Example :Use max. output = 2,3 L/H. If the pump is set at 40%speed and 60% stroke lenght, the appropriate pump output is 2,3 L/H x 0.40 x 0.60 = 0,55 L/H.Note : Remember that 6x8 tubing is 0,22 ml/cm which is0,8 % wrong for 1 l measuring pot.2 Foot valve 10 Tee4 Pump 14 Graduate container(1 l min.)6 Pressure line E Suction lift8 Inj. check valveFig. 3.2a : CalibrationIII – 3. CALIBRATIONOnce installation is complete and the approximateoutput has been determined, the pump should becalibrated to adjust speed and stroke for your actualdesired output.1. If equipped (B7 – C7 series), make certain Pressurecontrol knob is turned fully clockwise.2. Be sure the pump is in normal service (i.e. includingfactors such as injection pressure, fluid viscosity,suction lift …).3. Place the foot valve in a graduated container.4. Start the pump at maximum frequency and let it runto remove air trapped in suction line (bleed valveopen when using a 4FV). Close bleed after priming.5. Turn the pump off. Refill graduated container to alevel strarting point.6. Using a stopwatch or timer, turn the pump on for ameasured amount of time (50 pump strokesminimum). The longer the time period, the moreconfident you can be of the results.III - 1LMI, Doseur à membrane, L001, Rev.B, 1098

III – 4. VOLUMETRIC CALIBRATION INEXTERNAL MODE1. Since pump output is governed by an external devicesuch as Flowmeter-pulser, Liquitron Current-tofrequencyconverter or 4-20 mA DC signal from aninstrument with an LMI Analog-to-digital converter,only the ouptut per stroke may be calibrated.2. With pump primed and discharge tubin connected tothe injection point as it would be in normal service,place foot valve in a graduated container.3. Swtch pump to Internal mode with speed knob set at100 until air is exhausted from suction line and pumphead.4. Adjust control pressure (B7 – C7 series).5. Turn the pump off. Refill graduated container to alevel strarting point.6. Switch pump on and count the number of strokes.For a good accuracy, count at least 100 strokes.Switch pump off.7. Note the volume pumped during the calibrationperiod and the number of strokes. Divide into thevolume the number of strokes to determine thevolume of solution pumped per stroke.8. Adjust stroke length knob to desired value refering tocalibration.III – 5. PRESSURE CONTROLAdjust pressure control (B7 - C7 series) : while unit isrunning, turn pressure control knob fully clockwise thenturn slowly counter-clockwise until unit just begins tostall. This is the optimmum pressure control setting foryour installation. Adjust pressure control to prolongpump life.Increase setting if back pressure is increased.F : Excess pressureFig. 3.3a : Control pressureNote : On series A9, B9, C9, this setting is in the mainmenu.III - 2LMI, Doseur à membrane, L001, Rev.B, 1098

PART IV – MAINTENANCEIV – 1.

IV – 3. TROUBLESHOOTINGPump will not prime• Pump not turned on or plugged in.Turn on pump/plug in pump.• Output dials not set properly.Always prime pump with speed at 80 % and strokeat 100 %.• Foot valve not in vertical position on bottom of tank.See Chapter II – 1. Section Foot valve/ceramicweight.• Pump suction lift too high.Maximum suction lift is 1,5 m. Pump with Highviscosity liquid handling assemblies require floodedsuction.• Suction tubing is curved or coiled in tank.Suction tubing must be vertical. Use ceramic weightsupplied with pump. (see Chapter II – 1. SectionFoot valve/ceramic weight).• Fittings are over tightened.Do not overtighten fittings. This causes seal rings todistort and not seat propertly which causes pump toleak back or lose prime.• Air trap in suction valve tubing.Suction tubing should be as vertical as possible.AVOID FALSE FLOODED SUCTION (see ChapterII – 1. Section Flooded suction).• Too much pressure at discharge (pump without 4-function valve).Shut off valves in pressurized line. Disconnecttubing at injection check valve (see Chapter III – 1.Priming). When pump is primed, reconnectdischarge tubing.Pump loses prime• Solution container ran dry.Refill container with solution and reprime (see PartIII).• Foot valve not in vertical position on bottom of tank.See Chapter II – 1. Section Foot valve/ceramicweight.• Pump suction lift too high.Maximum suction lift is 1,5 m. Pump with Highviscosity liquid handling assemblies require floodedsuction.• Suction tubing is curved or coiled in tank.Suction tubing must be vertical. Use ceramic weightsupplied with pump. (see Chapter II – 1. SectionFoot valve/ceramic weight).• Fittings are over tightened.Do not overtighten fittings. This causes seal rings todistort and not seat propertly which causes pump toleak back or lose prime.• Air trap in suction valve tubing.Suction tubing should be as vertical as possible.AVOID FALSE FLOODED SUCTION (see ChapterII – 1. Section Flooded suction).• Air leak on suction side.Check for pinholes, cracks. Replace if necessary.Leakage at tubing• Worn tubing ends.Cut tubing about 25 mm (1’’) off tubing and thenreplace as before.• Loose or crack fitting.Replace fitting if cracked. Carefully hand tightenfittings. Do not use pipe wrench. Once fitting comesinto contact with seal ring, tighten an additional 1/8or ¼ turn.• Worn seal rings.Replace balls and seal rings (see part IV).• Solution attacking Liquid handling assemblymaterial.Consult Technical Assistance Department foralternate materials compatible with the pumpedsolution.Low output or failure to pump againstpressure• Pump’s maximum pressure rating is exceeded byinjection pressure.Injection pressure cannot exceed pump’s maximumpressure. See pump data plate.• Worn seal rings.Replace them : see Chapter IV –1.• Ruptured diaphragm.Replace diaphragm : see Chapter IV –1. SectionDiaphragm replacement.• Incorrect stroke length.Check zero on pump/Re-zero pump (See ChapterIV – 2.).• Tubing run on discharge may be too long.Longer tubing runs may create frictional lossessufficient to reduce pump’s pressure rating.• Clogged foot valve strainer.Remove foot valve strainer when pumping slurriesor when solution particles cause strainer to clog.Failure to run• Pump not turned on or plugged in.Turn on or plug in pump. Check also programming(A9, B9, C9 Series).• EPU failure.Disassemble pump and measure the resistance ofthe EPU across the EPU wires. Resistance readingshould be in accordance to the table (see ChapterIV – 4.). Also check EPU leads to ground.• Pulser failure.The pulser should be replaced if EPU checks outOK.IV - 3LMI, Doseur à membrane, L001, Rev.B, 1098

Foot Valve/Suction TubingInstallationThe Foot Valve acts as a check valve to keep the pumpprimed in suction lift applications.The foot valve is designed to be submersed in thesolution tank or drum and must sit in a vertical positionat the bottom. Position approximately 2 inches (50mm)off the bottom if the tank or drum contains sediment.The ceramic weight, when installed, positions the footvalve in a vertical position.Multi-Function Valve InstallationTo install the multi-function valve, remove the yellowscrew cap on the top of the pump head and screw inthe valve so that it contacts the seal ring. An additional1/8 – 1/4 turn may be necessary to prevent leakage.1/4" O.D. tubing connects to the side of the valve andacts as a return line to the solution tank. To ensurepriming, this tubing must NOT be submerged in thesolution.This return line tubing must be secured to ensurepumped solution will safely return to supply tank.NOTE: Pump models equipped with high-viscosityliquid end s are not equipped with foot valves. Floodedsuction is recommended A 1/2" NPT connector isincluded for flooded suction installations.Coupling nut¼ ” TubingDischarge1. Cut a piece of suction tubing to a length so that thefoot valve hangs just above the bottom of thesolution container. Maximum recommendedvertical suction lift is 5 feet (1.5 m).2. Attach the foot valve to one end of the suctiontubing.3. Slide the ceramic weight over the tubing end untilit contacts the top of the foot valve coupling nut.4.

Plug in or switch the pump on.2. While the pump is running, set the speed knob at80 %and the stroke knob at 100%.If the pump is equipped with pressure control, turn fullyclockwise.3. 1/4 turn open the relief side (black knob) of themulti-function valve.3A.

The suction tubing should begin to fill with solutionfrom the tank.5. A small amount of solution will begin to dischargeout the return line of the multi-function valve. Oncethis happens,1/4 turn or release the knob andSHUT THE PUMP OFF. (If pump is not equippedwith an on/off switch, or disconnect the powercord.)6. The pump is now primed.6A. (Bleed 4FV only)a. Start pump and let pump inject solution intothe discharge line.b. Close the bleed adjustment screw by rotatingit clock-wise with a screwdriver.c. Now adjust the pump stroke length and/orspeed (frequency) to a range approximately25% higher than you would normally want forthe process.d. Slowly rotate bleed adjustment screw counterclockwiseuntil just a small amount of solutionbegins to trickle down inside the bleed returntubing. A small amount of solution pumpedback to the tank with each stroke of the pumpwill allow gas and air to escape without air orgas locking in the pump head.NOTE: If the pump does not self-prime, remove themulti-function valve on the discharge side of the pumphead. Remove the check valve and pour water orsolution into the port until the head is filled.
