Safe installation, operation, and maintenance of ITT Goulds equipment are an essential end-user responsibilities. ThisInstruction, Operation, and Maintenance (IOM) manual identifies specific safety risks that must be considered at all timesduring product life. Understanding and adhering to these safety warnings is mandatory to ensure personnel, property, and/or theenvironment will not be harmed. Adherence to these warnings alone, however, is not sufficient it is anticipated that the enduser will also comply with industry and corporate safety standards. Identifying and eliminating unsafe installation, operating andmaintenance practices is the responsibility of all individuals involved in the installation, operation, and maintenance of industrialequipment.

Specific to pumping equipment, two significant risks bear reinforcement above and beyond normal safety precautions.

! WARNING

1

Operation of any pumping system with a blocked suction and discharge must be avoided in all cases. Operation, even

for a brief period under these conditions, can cause superheating of enclosed pumpage and result in a violentexplosion. All necessary measures must be taken by the end user to ensure this condition is avoided.

! WARNING

2Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for assembl-

ing pumping units. These methods must be adhered to. Specifically, applying heat to impellers and/or impeller retain-

ing devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly expand and result in a violent

explosion and injury.

Please take the time to review and understand the safe installation, operation, and maintenance guidelines outlined in thismanual.

GENERAL DESCRIPTION

The Model VIT pump is a vertical industrial turbine typepump which is designed to meet many wide ranges ofservice. The VIT pump features capacities to 60,000 GPM(13,630 m3/h), heads to 4500 feet (1372 m), and pressuresto 3000 PSIG (210 kg/cm2).

DRIVERSWhere mechanical seals are required, the most commontype of drivers supplied are solid shaft electric motors withadjustable spacer type couplings. Solid shaft drivers are

recommended when mechanical seals are used. This willpermit the replacement of the mechanical seal withoutdisturbing the driver. Solid shaft right angle gear drives arealso used occasionally. When packed stuffing boxes areused with open lineshaft pumps, or if the pump unit is ofthe enclosed lineshaft / oil lubricated type, hollowshaftmotors or right angle gear drives are often used with aseparate driveshaft through the driver and connected to the

pump by a rigid flanged coupling.

DISCHARGE HEADThe discharge head is a fabricated "L" type head. Ports are

provided for connecting the discharge gauge, stuffing boxor mechanical seal bypass return. The driver support

portion of the discharge head is designed with large handholes for easy mechanical seal or stuffing box adjustment.

COLUMNFlanged column construction provides positive shaft and

bearing alignment, and also ease of assembly and

disassembly. Bearings are spaced to provide vibration freeoperation below the shaft first critical speed in order toinsure long bearing and shaft wear. The lineshaft issupported within the column by use of bearing retainerswithin the column assembly. These retainers are usuallyintegrally fabricated for all diameters.

VIT IOM 6/07 15


16/76

BOWL ASSEMBLYThe bowls are generally of flanged construction foraccurate alignment and ease of assembly and disassembly.Impellers may be either open or enclosed, depending on thedesign requirements. For temperatures over 1800 F(820 C) and in the larger size bowls, impellers are keyedto the shaft. A special first stage low NPSH impeller may

be provided in certain applications.

THRUST POTA thrust pot is utilized when the driver is not designed tocarry the pump thrust.

! When pumping unit is installed in a potentially explosive atmosphere, the instructions after the Ex symbol must befollowed. Personal injury and/or equipment damage may occur if these instructions are not followed. If there is anyquestion regarding these requirements or if the equipment is to be modified, please contact a ITT Gouldsrepresentative before proceeding.

FOUNDATION/PIPING

SUB BASE (SOLE PLATE)INSPECTIONSub Base and Sole Plate are terms in common use todescribe a general class of solid steel plates mounted ingrout (or bolted to steel structures) at the pump-foundationinterface.

1. Remove the Sub Base from the Pump Discharge Head,when shipped assembled.

2. Completely clean the underside of the Sub Base. It issometimes necessary to coat the underside of the SubBase with an epoxy primer. This may have been

purchased as an option.

3. Remove the rust preventative solution from themachined topside with an appropriate solution.

SITE WITH CONCRETEFOUNDATION

1. A pump should have adequate space for operation,maintenance, and inspection.

2. Sub Base mounted pumps are normally grouted on aconcrete foundation, which has been poured on a solidfooting. The foundation must be able to absorb anyvibration and to form a permanent, rigid support forthe pumping unit.

3. The foundation must be of adequate strength tosupport the complete weight of the pump, plus the

weight of the liquid passing through it. A typicalinstallation will have bolts with a pipe sleeve 2 1/2times the bolt diameter embedded in the concrete,sized and located in accordance with the dimensionsgiven on the Pump Certified Outline Drawing. The

pipe sleeve allows movement for final positioning ofthe foundation bolts to conform to the holes in the SubBase flange. Fig. 1 shows a typical installation.

VIT IOM 6/07 17


18/76

! All equipment being installed must be properlygrounded to prevent unexpected static electricaldischarge. If not, a static electric discharge mayoccur when the pump is drained and disassembledfor maintenance purposes.

4. Remove water and/or debris from anchor boltholes/sleeves prior to grouting. If the sleeve type boltsare being used, fill the sleeves with packing or rags to

prevent grout from entering.

5. Carefully lower the Sub Base onto the foundationbolts. Hand tighten the bolt nuts.

6. Leveling the Sub Base may be done by severalmethods. Two common methods are:

A. Leveling wedges. This is shown in Fig. 2.

B. Leveling nuts on the anchor bolts.

Regardless of the method, a machinist level must beused for leveling.

NOTE: When using a machinist level, it is importantthat the surface being leveled is free of allcontaminants, such as dust, to ensure an accuratereading.

7. Level the Sub Base in two directions at 90 degrees onthe machined surface. The levelness tolerance is 0.005inches per foot for commercial, and 0.001 inches perfoot for API.

SUB BASE GROUTING

1. Inspect foundation for dust, dirt, oil, chips, water, etc.and remove any contaminants. Do not use oil-basedcleaners as grout will not bond to it. Refer to groutmanufacturer's instructions.

2. Build dam around foundation. Thoroughly wetfoundation.

3. Pour grout between Sub Base and concrete foundation,up to level of dam. Remove air bubbles from grout asit is poured by puddling, using a vibrator, or pumping

the grout into place. Non-shrink grout is recommended.

4. Allow grout to set at least 48 hours.

5. Tighten foundation bolts.

SITE WITH STRUCTURAL STEELFOUNDATION

1. When the pump is mounted directly on a structuralsteel frame, pumps shall be located directly over, or asnear as possible, to the main building members, beams,or walls. The Discharge Head mounting flange, or Sub

Base, shall be bolted to the support to avoid distortion,prevent vibration, and retain proper alignment.

2. If a Sub Base is being bolted to a structural steelfoundation, or the Sub Base is not grouted to theconcrete foundation, use shims for leveling the plate.

PIPINGGuidelines for piping are given in the "Hydraulic InstituteStandards" available from: Hydraulic Institute, 9 SylvanWay, Parsippany, NJ 07054-3802 and must be reviewed

prior to pump installation.

s! WARNINGNever draw piping into place by forcing at the flangeconnections of the pump. Pipe strain will adverselyeffect the operation of the pump resulting in physicalinjury and damage to the equipment.

1. All piping must be supported independently of, andline up naturally with, the pump flange.

2. DO NOT connect piping to pump until grout hashardened and pump hold down bolts have beentightened.

3. It is suggested that expansion loops or joints, if used,be properly installed in discharge line when handlingliquids at elevated temperatures, so linear expansion of

piping will not draw pump out of alignment.

4. Carefully clean all pipe parts, valves and fittings, andpump branches prior to assembly.

5. Isolation and check valves should be installed in

discharge line. Locate the check valve betweenisolation valve and pump, this will permit inspection ofthe check valve. The isolation valve is required forregulation of flow, and for inspection and maintenanceof pump. The check valve prevents pump or sealdamage due to reverse flow through the pump whenthe driver is turned off.

6. Increasers, if used, should be placed between pumpand check valves.

7. Cushioning devices should be used to protect the pumpfrom surges and water hammer if quick-closing valvesare installed in the system.

FINAL PUMP CHECK

1. Rotate shaft several times by hand to be sure that thereis no binding and all parts are free.

2. Check alignment, per the alignment procedure outlinedin the Operation section to determine absence of pipestrain. If pipe strain exists, correct piping.

PUMP INSTALLATION

!When pumping unit is installed in a potentially explosive atmosphere, the instructions after the Ex symbol must befollowed. Personal injury and/or equipment damage may occur if these instructions are not followed. If there is anyquestion regarding these requirements or if the equipment is to be modified, please contact a ITT Gouldsrepresentative before proceeding.

Pumps 20 feet (6m) or less in length are usually shippedassembled, with the exception of the driver, packing,mechanical seal with tubing and coupling assembly, spaceror non spacer type. When provided, refer to the CertifiedPump Outline for the applicable baseplate plan for locationof anchor bolt holes.

INSTALLING A PARTIALLYASSEMBLED PUMP

1. If a baseplate was supplied, install as described in theFoundation/Pipingsection.

2. Clean the plate mounting flange and clean bottomsurface of discharge head mounting flange.

3. Sling through discharge hand holes or thread twoeyebolts through bolt holes in mounting flange andhoist unit into position over foundation.

NOTE: Eyebolts or sling should be rated to handle inexcess of the pump weight (see Outline Drawing).

4. Lower the unit and carefully guide it so that unit doesnot strike the sides of the baseplate. Continue to lowerunit until the discharge head flange engages and restsfirmly on the plate, then secure with capscrews

provided.

5. When a lineshaft is shipped separately, check shaft forstraightness; average total runout should not exceed0.005" T.I.R. (0.127mm) for every 10 feet (3m). Shaft

must be within tolerance prior to installation.

6. Remove stuffing box (if installed) and carefully slideshaft through top column bearing retainer and threadinto coupling after replacing stuffing box or sealhousing. Use extreme care not to damage bearingretainer.

7. Refer to the remainder of this manual for completeassembly, startup, maintenance, disassembly andrecommended lubricants for the pump.

INSTALLING THE BOWL ASSEMBLY

The following bowl installation instructions apply to pumpsshipped disassembled.

s! WARNINGDo not work under a heavy suspended object unlessthere is positive support and safe guards which willprotect personnel should a hoist or sling fail.

$ CAUTIONDo not attempt to lift bowl assembly by the pumpshaft.This can result in damaging the pumpshaft.

1. Prior to installing the bowl assembly, check that allcapscrews are tight and any integral piping is installed.Remove all accumulated dust, oil, or other foreignmaterial from the external surfaces.

2. Place two I-beam supports across the baseplateopening strong enough to safely support the weight ofthe entire pump assembly. These I-beams should beconnected by threaded rods and nuts so as to clampthem firmly together for the portion to be supported(See Fig. 3).

3. Put in place a suitable hoist or derrick over baseplateopening. Place the elevator clamps just below thedischarge bowl flange or install two threaded eye boltsthrough bolt holes in flange 180apart.

4. Attach sling to elevator clamps or eye bolts and hoistinto position over foundation opening (See Fig. 3).

5. Carefully lower bowl assembly, guiding the unit so itdoes not strike the sides of the opening. Continue tolower bowl assembly until the elevator clamps ordischarge bowl flange rests firmly on the I-beamsupports.

6. Place a cover over the discharge bowl opening toprevent entrance of dirt or other foreign matter.

$! CAUTIONDo not drop any foreign object into the bowl assembly.Such an object can cause serious damage to the pumpand any downstream components. Any foreign objectdropped into the bowl assembly must be retrieved priorto continuing assembly.

THREADED COUPLINGINSTALLATION

$! CAUTIONUse "MOLYKOTE" Dow-Corning or equal for allgalling material such as 316 stainless steel.

NOTE: Shaft threads are left hand.

When the threaded coupling is not installed on the

pumpshaft, install as follows:1. Coat the threads with a light coat of oil for a

non-galling material, or Molykote for galling material.

2. Install threaded coupling onto pumpshaft by threadingit on for one-half its length. A fine wire inserted in thedrill hole at the center of the coupling can be used as agauge to determine when the coupling is correctly

positioned on the pumpshaft. Remove the wire afterinstalling the coupling.

2. If the stuffing box is assembled to the head, remove itand all attached piping. See Fig. 9 for the applicablestuffing box provided for the pump being assembled.Remove coupling guard if provided.

! Packed stuffing boxes are not allowed in an ATEXclassified environment.3. When a mechanical seal is provided, it is usually

shipped separately. In case the seal is assembled to thedischarge head, remove the seal prior to installing thehead. See Dissassembly / Reassembly section forremoval of the seal.

!The mechanical seal used in an ATEX classifiedenvironment must be properly certified.

4. Remove coupling guard if provided. Attach a slingthrough windows (hand holes) or thread two eyeboltsin the head driver support mounting holesdiametrically opposite and hoist discharge head overthe protruding headshaft. NOTE: Eyebolts or slingshould be rated to handle in excess of the pump weight(see Outline Drawing).

$ CAUTIONDo not bump or scrape the shaft protruding above thecolumn. This could result in bending or damaging the

shaft.

5. Orient the discharge head in the required position andlower the head centering the vertical hole with theheadshaft protruding above the column until thedischarge head engages the column. Install capscrews

and secure discharge head to column. Tightencapscrews gradually in diametrically opposite pairs.

6. Lift pump assembly high enough to allow rotation ofthe supports. Realign and lower assembly. Install andtighten remaining capscrews. Repeat rotation andtightening procedure until all capscrews are uniformlytight.

7. Using a device with the capacity to support the weightof the entire pump assembly, hoist bowl, column, andhead assembly and remove supports.

TENSIONING THE ENCLOSING TUBE

The enclosing tube sags from its own weight as it isinstalled and must be pulled tight (tensioned) to make itstraight. This section describes two methods of tensioningthe tube. The direct pull method is more precise and is

preferred. The second method the wrenching method

is given as an alternate.

NOTE: The correct tension is equal to the weight ofthe enclosing tube plus 10%.

Weights per unit length for each tube size are given inTable 1. Multiply by total length of the tube to determinethe total weight.

2 7.66

3 10.25

3 12.50

4 14.98

5 20.78

6 28.57

DIRECT PULL METHOD

1. The upper end of the tube may be pulled by the hoistto obtain the predetermined tension value. Thisrequires the use of a dynamometer scale and an adapterfitting to grip the tube (TUBE TENSION ADAPTERAVAILABLE THROUGH FACTORY). With thetension plate installed manually but not tightened,thread the special fitting onto the top of the tube to fullengagement. Attach the dynamometer scale to thefitting, and connect the upper end of the scale to thehoist hook. Operate the hoist hook to apply therequired tension. This should pull the tension plate offthe discharge head. Manually thread the tension plateto reset it. Release tension, remove dynamometer scaleand special fitting.

WRENCHING METHOD

1. If a dynamometer is not available, the tube can betensioned by wrenching the tube tension plate. Makeup a spanner wrench to straddle the projectingthreaded tube end and to engage the tube tension platecapscrew holes by two lugs. Torque the tension plateto take all the slack out of the shaft tubing and induce areasonable amount of tension by turning the tension

plate counterclockwise. For tubing 2-1/2" (63.5mm)and larger, a man's full strength on a 3 foot (915mm)lever arm is sufficient. For smaller sizes, less pull must

be exercised.

NOTE: Do not turn clockwise to align holes in tension

plate and discharge head.

INSTALLING TENSION NUT

1. (See Fig. 8). Install capscrews (760) in the tensionplate. Pour one pint of oil down the oil tube.

2. Install packing (620) in the tension plate and thread thetension nut (626), tightening it firmly against the

packing.

3. If a packed type tension nut (626) is used (for waterflush), install packing (620), packing gland (618) andsecure with stud (739) and nut (735). Screw nut fingertight. Install line assembly (635) and connect to flushliquid supply (See Fig. 8).

$ CAUTIONBe sure that the top of the enclosing tube does notinterfere with the tension nut.

4. If the top of the tube interferes with the tension nut,determine the distance, if the tube is too long or tooshort. If the tube is too short, it must be replaced with alonger tube of the correct length. If the tube is toolong, it must be cut to the correct length andre-threaded. Reinstall and re-level pump.

MECHANICAL SEAL INSTALLATION

! The mechanical seal used in an ATEX classifiedenvironment must be properly certified.Instructions for installing mechanical seals are provided bythe seal manufacturer. Consult the seal manufacturer'sinstructions (furnished with the seal) for information on thetype of seal used. Additionally, refer to factory furnishedoutline drawing and seal piping schematic on complex seal

piping arrangements.

GENERAL REQUIREMENTS FORALL SEALSThe vertical turbine pumps are usually supplied withcartridge type mechanical seals, shipped assembled - readyfor installation, when mechanical seals are supplied. Theexceptions are the Outside Mounted Seals (Fig. 14) and theSplit Seals (not shown).

1. Check surfaces at the face of the seal housing and atthe bottom of the seal housing to insure that they areclean, flat and free of burrs. The face surface must besmooth to form a good sealing surface for a gasket orO-ring.

2. Check that shaft is smooth, and free of burrs, nicks andsharp corners that could ruin the O-ring or shaft

packing. When further clean up is required, protect bycovering the inside of the pump seal housing. Remove

burrs, nicks, and sharp corners by using a strip ofemery cloth "shoeshine fashion" over the shaft threads.File threads around the keyway with a smooth mill fileor emery cloth. Sharp edges must be rounded.

3. Remove all chips and dust from the shaft area.

4. Check that all rotary unit parts of the seal fit over theshaft. A pre-check may be made by removing theO-ring(s) from the cartridge sleeve Inside Diameter(ID) and then installing the seal on the shaft. Furthershaft clean up will be necessary when the seal will not

pass all the way into the seal housing.

5. Remove the seal after the pre-check, and re-install thesleeve O-ring(s).

$ CAUTIONSparingly lubricate the shaft and sleeve ID with thelubricant included with the mechanical seal orrecommended by the mechanical seal manufacturer.The following lubricants may be used for water servicewhen no lubricant is supplied or recommended by themechanical seal manufacturer.

Light Oil (SAE #10 or 20)

Dow Corning #4 Grease

Silicone lubricant

Wax or Clay

Soapy Water

Oil based lubricants will damage EPR / EPDM elastomerO-rings. Silicone lube and soapy water are safe for EPR /EPDM elastomer O-rings.

6. Install the O-ring or gasket, between the seal housing

and seal. Install the seal over the shaft and ease it intoposition against the face of the seal box. Take carewhen passing the sleeve and O-ring over keyways orthreads to avoid damaging the O-ring.

$ CAUTIONDo not bump carbon members against the shaft as theymay chip, crack or break.

7. Position seal gland on discharge head seal housing andsecure with capscrews (or nuts for studs) provided.Tighten capscrews gradually and uniformly in acriss-cross pattern, taking 2 or 3 passes.

$ CAUTIONDo not overtighten capscrews on gland. This candistort seal seat and cause seal failure.

8. Install all seal piping as required. Prior to making finalconnections of sealing liquid pressurizing lines, makesure the seal housing and all sealing liquid lines areflushed free of dirt, scale and other particles that would

be abrasive to the sealing faces.

9. The driver and coupling must now be installed beforethe mechanical seal installation can proceed. See

Installation of a Solid Shaft Driver Secion orInstallation of a Hollow Shaft DriverSection as

appropriate.

10. The following flatness and concentricity measurementsmay be taken at this time.

A. Concentricity of Driver Shaft. See Fig. 10. Installdial indicator as shown, with the base attached tothe motor support. Rotate driver shaft by handwhile checking dial for reading. Runout shouldnot exceed NEMA standards, 0.002 in. (0.05mm)maximum Total Indicated Runout (TIR). Ifindicator reads above 0.002 in. (0.05mm) TIR,loosen the four driver tie down bolts and re-locatedriver on motor base register. Obtain desired

position. Tighten tie down bolts. Repeat indicatorreading.

VIT IOM 6/07 33


34/76

B. Flatness of Seal Housing. See Fig. 11. Thismeasurement may require that the mechanical seal

be removed in the event that the dial indicatorstylus cannot rotate 360 degrees on the top surfaceof the seal gland. With the lower couplingcomponents removed, attach the base of the dialindicator to driver shaft. Place the stylus at the topsurface of the seal gland, or at the top surface of

the seal housing. Rotate the driver shaft slowly360 degrees. Check that the face of the sealhousing is square with the shaft to within 0.002 in.(0.05mm) TIR.

C. Concentricity of Seal Housing. See Fig. 12. Thismeasurement will require that the mechanical seal

be removed. Install dial indicator as shown. Byrotating driver shaft by hand, run indicator in theinside machined surface of the seal housing todetermine concentricity. If indicator reads above0.004 in. (0.10mm) TIR, loosen the four driver tiedown bolts and re-locate driver on motor baseregister. Obtain desired position. Tighten tie down

bolts. Repeat indicator reading.

D. Concentricity of Head Shaft. See Fig. 13.Re-install the mechanical seal if it was removedfor the Flatness or Concentricity measurement.Install the coupling assembly and make theimpeller adjustment as described under

IMPELLER ADJUSTMENTin the Installationsection. Attach the base of the dial indicator on thedischarge head or driver support. Place the styluson the shaft between the top of the seal and the

bottom of the pump coupling. Rotate the drivershaft slowly 360 degrees. Check that the shaftrunout is within 0.004 in. (0.10mm) TIR, or as

required by specification. Drill and dowel pin inthree places to secure driver to motor base afterobtaining required runouts.

$ CAUTIONDo not remove seal spacer or eccentric washer, adjustseal, or tighten setscrews until after impellers areadjusted.

12. Save the seal spacer or eccentric washer, as they may

be used to hold the correct seal spacing in the eventthat the seal must be removed. The seal setscrews mustbe loosened to re-adjust the impeller(s).

$ CAUTIONReset the seal after impellers are adjusted.

13. Seals using half dog setscrews may require that theshaft be spot faced/drilled, to provide a secure

placement. Cover the seal and seal housing. Removethe setscrews one at a time from the collar and spotface/drill the shaft. Then tighten the setscrews into

position. Remove any metal chips to avoid damagingseal.

SINGLE INSIDE MOUNTED SEALS(See Fig. 14)These seals will be cartridge seals, complete with glandsand sleeves, assembled as a unit by the seal manufacturer.The seal manufacturer's special instructions must befollowed in the event that non-cartridge seals are to beinstalled.

1. When the seal is an O-ring type, assemble thecomplete unit over the shaft. Take care when passingthe sleeve and O-ring over keyways or threads to avoiddamaging the O-ring.

2. If the seal is the teflon wedge ring type, remove the

sleeve collar and teflon wedge ring and assemble themseparately after the sleeve is in position. Tighten thecollar on the threads to seal teflon wedge around theshaft.

SINGLE OUTSIDE MOUNTEDSEALS (See Fig. 14)These seals will be provided in two sub-assemblies, thestationary unit and the rotary unit.

1. Install the stationary unit, which is the seal glandassembly, as instructed in General Requirements for

All Seals. The stationary face will face up.

2. Install rotary unit, take care not to disengage rotaryparts. If rotary unit parts become disengaged,installation becomes difficult.

3. Do not tighten setscrews or adjust seal at this time,until impellers are adjusted.

4. To adjust seal, refer to the spring gap which is stampedon the collar and shown on the assembly drawing.Tighten setscrews so that the compression ring ismaintained at the same distance from the collar at all

points. Before starting the pump, check to insure thatthe spring gap and the distance from the face of the

stuffing box to the collar are the same as shown on theseal assembly drawing.

HIGH PRESSURE SEALS(See Fig. 14)High Pressure seals are usually cartridge seals, shippedassembled, ready for installation. High Pressure seals may

be either Single or Dual seals.

1. Mechanical seals on pumps with over 1200 PSI (85kg/cm2) gauge discharge pressure, or as specified by

the seal manufacturer, are normally fitted with "backuprings." These rings are installed following sealinstallation, between the drive collar of the seal and the

bottom of the flanged pump coupling, (See Fig. 14).Install backup ring as follows:

A. Screw the bottom backup ring into the top backupring until it bottoms out.

B. Slide backup ring assembly over the shaft andposition it on the seal.

2. Adjustment of the backup ring assembly shall becompleted after the spacer coupling and driver areinstalled, after the seal is set in position and after

checking total indicated runout on the headshaft abovethe mechanical seal as stated in "General Requirementsfor All Seals," 11.A.

DUAL SEALS (Tandem And Double)(See Fig. 15)Dual seals are cartridge seals, shipped assembled. Thefollowing instructions would only apply if a non-cartridgetype seal is furnished, and there are no instructions

provided by the seal manufacturer.

1. Scribe a mark on the shaft or sleeve exactly flush withthe face of the seal housing. This is the "referencemark" for setting the seal to the seal assembly.

2. Lubricate the stuffing box bore and O.D. of inner (orlower) stationary insert with lubricants described inGeneral Requirements for All Seals, paragraph 6.Protect inner inset face with soft clean material, suchas gasketing or sheet rubber and install into the bottomof the seal housing, with hand pressure only. If theinsert includes a holding pin, be sure the pin is alignedwith the slot or hole in the bottom of the seal housing.

3. Carefully place gland ring and outer (or upper)stationary insert over the shaft.

4. Lubricate shaft or sleeve before installing any of therotary unit parts.

5. Install seal collar or collars on the shaft or sleeve andlocate collar or collars in the relation to established"reference mark" and to setting dimension given on theseal assembly drawing. Lock the collar to shaft orsleeve by tightening setscrews.

6. Install the remaining rotary unit parts on the shaft orsleeve in the proper sequence and complete theassembly of equipment.

7. Shaft packing (if provided, depending on seal type)shall be installed on the shaft or sleeve individuallyand with care to avoid nicks or damage that wouldcause seal to leak.

8. Seat the gland ring and gland gasket to the face of theseal housing by tightening the nuts or bolts evenly andfirmly. Be sure the gland ring is not cocked. Tightennuts or bolts just enough to seal at the gland ring

gasket.

INSTALLING THE DRIVER

! When installed in a potentially explosiveenvironment, please ensure the motor is properlycertified.

INSTALLATION OF A SOLID SHAFTDRIVER

NOTE: When pump is supplied with a thrust pot, donot secure driver to discharge head until after thethrust pot and flexible coupling are installed. (Aseparate supplement for thrust pots will be furnished asrequired).

s! WARNINGDo not work under a heavy suspended object unlessthere is a positive support and safe guards which willprotect personnel should a hoist or sling fail.

!Serious damage may result if pump is run in thewrong direction.

The coupling between the driveshaft and discharge headshaft may be a nonspacer type (See Fig. 17), or a spacertype (See Fig. 18). The latter is used on pumps furnishedwith a mechanical seal to permit servicing of the sealwithout removal of the driver.

1. Driver support. When a driver support is furnished andnot installed, proceed as follows:

A. Hoist driver support, inspect the mountingsurfaces, register, and clean these surfacesthoroughly.

B. Install driver support on discharge head and securewith capscrews provided.

2. Attach a sling to the lifting lugs of driver, hoist motor,inspect the mounting surface, register, and shaftextension, and clean these surfaces thoroughly. If any

burrs are found, remove burrs with a smooth mill file,cleaning thoroughly afterward.

3. Orient the motor conduit box in the required position.Align the motor mounting holes with the matingtapped holes on the discharge head. Lower the motoruntil the registers engage and the motor rests on thedischarge head. Secure motor with capscrews

provided.

4. On drivers having a nonreverse ratchet or pins,manually turn the driver shaft clockwise viewed fromthe top until the nonreverse ratchet or pins fullyengage.

5. Lubricate motor bearings in accordance withinstructions given on lubrication plate attached to themotor case.

NOTE: Please read and follow the motormanufacturer's instructions before lubricating themotor bearings. Too much lubricant can cause thebearings to overheat and fail prematurely.

s! WARNINGThe motor must not be tested for direction of rotationwhen coupled to the pump. If pump should rotate inthe wrong direction, serious damage to the pump andmotor would result. Also serious injury to personnelcould result.

6. Make temporary electrical connections according totagged leads or diagram attached to the motor. Motormust rotate counter-clockwise when viewed from thetop. See arrow on pump nameplate. If motor does notrotate counter-clockwise, you can change the rotation

by interchanging any two leads (for three phase only,for single phase motors see motor manufacturer'sinstructions.)

7. Motor shaft end play adjustment: if required, motorshaft end play shall be checked with a dial indicator

prior to connecting the pump coupling to the solidshaft motor. Consult the applicable motormanufacturer's instruction manual for detailedinformation on motor shaft end play.

COUPLING INSTALLATION: (Figs. 17 & 18)

1. Apply a thin film of oil on the pump key (730) andinsert key into headshaft keyway seat.

2. Gently lower pump hub of coupling (614) ontoheadshaft.

3. Thread on the adjusting plate (613) onto the headshaftuntil flush with top of the headshaft.

4. Apply a thin film of oil to the driver key (730) andinsert key into drive shaft keyway seat. Place thedriver hub (610) onto the drive shaft and with key slideit up the drive shaft until the annular groove isexposed. Install split ring (722) in the groove and slide

driver hub down over the split ring to capture it.

5. If the pump is supplied with an adjustable spacercoupling (See Fig. 18), install spacer (612) betweenheadshaft and driveshaft hubs. Secure with capscrews(759) and hex nuts (735).

IMPELLER ADJUSTMENT

Impeller adjustment is identical for all motors and rightangle gear drives. Adjustment is accomplished by turning

the adjusting plate (613) (See Fig. 19 or 20). The correctadjustment is listed on the Outline Drawing for the specificunit.

NOTE: Mechanical seal, when provided, must not besecured to the shaft prior to impeller adjustment (openor enclosed type impeller's). Shaft must move up ordown within the seal assembly.

NOTE: For pumps handling liquids between -50 to200 F, impeller adjustments can be made underambient conditions. For liquids in excess of thisrange, it is recommended that impeller adjustment bemade after the pump surface temperature hasreached an equilibrium when charged with thepumpage. In those cases, where this is not feasibledue to safety considerations or impossible due toexternal ice build up in cryogenic applications, referto factory for specific instructions.


OPEN IMPELLERS

1. With the impellers touching the bottom of the bowls,turn the adjusting plate (613) towards the driver hub

(610) or spacer (612). Obtain 0.015 inch clearancebetween the adjusting plate and driver hub or spacerfor the first 10 feet of column. Add 0.010" for eachadditional 10 feet of column. See Fig. 19 or 20.

NOTE: The determination of driver shaft end play canbe critical and should be added to this setting. Forlarger pumps over 8", this amount may be too little;please refer to Outline Drawing.

Example: total pump length is 50 feet - set impellers at0.055 inch.

2. After impeller adjustment, align adjusting plate (613)with the pump hub (614), and tightly draw coupling

flanges together with capscrews (759) and nuts (735).(See Fig. 19 or 20).

3. Set seal after impeller adjustment. Securely tighten allset screws in the collar. Remove the spacer betweenthe gland plate and collar. Retain spacer for futureresetting of seal.

NOTE: When impellers are reset, the seal must also bereset.

ENCLOSED IMPELLERS

1. For enclosed impellers obtain the clearance between

the adjusting plate and driver hub or spacer asspecified on the outline drawing. See Fig. 19 or 20.

INSTALLATION OF

SOLID SHAFT RIGHT ANGLE GEAR DRIVE


1. The coupling shown between the drive shaft and headshaft may be a non-spacer type (See Fig. 17) or aspacer type (See Fig. 18). The latter is used on pumpsfurnished with mechanical seal to permit servicing ofthe seal without lifting the gear.

2. Driver support: when a driver support is furnished andnot installed, proceed as follows:

A. Hoist driver support, inspect mounting surfaces,register, and clean these surfaces thoroughly.

B. Install driver support on the discharge head andsecure with capscrews provided.

3. Attach a sling to the eye bolts or lugs of gearhead.Hoist gearhead, inspect the mounting surface, register,and clean these surfaces thoroughly. If any burrs arefound, remove burrs with a smooth mill file cleaningthoroughly afterward.

4. Orient the gearhead with the input shaft in the requiredposition and align the mounting holes with the matingtapped holes in the discharge head. Lower the gearheaduntil the registers engage and the gearhead is set firmlyin place on the discharge head. Secure the gearhead

with capscrews provided.

5. On gearheads having non-reverse ratchet or pins,manually turn the shaft clockwise viewed from the topuntil the non-reverse ratchet or pins are fully engaged.

NOTE: Check the rotation of the power unit and pumpin relation to that of the drive as shown by arrows on thecase. Rotate the drive manually before applying powerchecking rotation. Do not operate in reverse direction ofthese arrows as serious damage or injury can occur.

6. Some gearheads are equipped with an oil coolingsystem which is supplied with cooling fluid from the

pump or an external source. Make cooling connections

with tubing or rubber hose. If pump fluid is to be used,connect a length of tubing and a flow-regulating valvebetween the inlet on the gearhead and outlet on thedischarge side of the discharge head, connect tubingfrom the outlet on gearhead back to sump or drain.

l! CAUTIONDo not use rigid pipe for this purpose. Rigid pipe issusceptible to leak at the joints due to vibration.

7. Fill the gearhead oil reservoir with a high grade ofturbine oil. If oil is not furnished with the gearhead,

select a suitable grade of oil from the manufacturer'slist. Consult the manufacturer's instructions for thefrequency of oil change and other data onmaintenance.

$ CAUTIONDo not use automotive oils.

8. Gearhead shaft end play adjustment. If required,gearhead shaft end play shall be checked with a dialindicator prior to connecting pump coupling to solidshaft gear. Consult the applicable gear manufacturersinstruction manual for detailed information ongearhead shaft end play.

9. Coupling installation. Follow instructions given in theInstallation section.

s! WARNINGMoving parts of the prime mover, coupling device, andgearhead must be covered with a suitable rigid guardin compliance with local regulations to prevent injuryto personnel.

10. Assemble the flexible shaft flanges on the gearheadinput drive and engine. The prime mover (engine orsteam turbine) must be mounted on a firm foundationin alignment with the gearhead. The driving and drivenshafts shall be within plus or minus one degree

parallel. Offset angle shall be one to five degrees formaximum coupling lift. Keep the lugs on flange yokesin the same position as shipped from the factory. If slip

joint is moved, be sure lugs are realigned or severeunbalance may result. Consult the applicablemanufacturer's instruction manual for detailedinformation on the prime mover (engine or steamturbine) and coupling or drive shaft. When a Fast typecoupling or equivalent is used instead of the doubleuniversal type of shaft used with engine drives, no"offset" between drive and driven shafts is permitted.
