1. INTRODUCTIONThis manual contains instructions for the installation, operation, and maintenance of your Ingersoll-Dresser centrifugal pump. The instructions are written for the use of personnel with a general trainingin the operation and maintenance of centrifugal pumps.

Your pump has been designed to provide safe and reliable service. However, it is both a pressurevessel and a piece of rotating machinery. Operators must exercise good judgment and observe correctsafety practices to avoid damage to the equipment and surroundings and to prevent personnel injury.

The pump has been designed for the pumping conditions specified in the customer’s order. Ingersoll-Dresser Pump Company must be consulted prior to any significant change of conditions.

1.1 SAFETYIt is assumed that your safety department has established a safety program based upon a thoroughanalysis of the hazards associated with your industry. Your safety program must be reviewed toensure that it covers hazards associated with high speed rotating machinery before installing,operating, or performing maintenance on the pump and associated components covered by thismanual. Correct installation and care of protective guards, shut down devices, and over pressureprotection equipment are essential to any safety program and must be included.

If applicable to your operating environment, your safety program must also cover hazards which arisefrom the presence of electrical power, hot oil, high pressure and temperature liquids, toxic gases andliquids, or flammable gases or liquids.

Also essential are special precautionary measures to prevent the possibility of applying power to theequipment at any time when maintenance work is in progress. The prevention of rotation due toreverse flow should not be overlooked.

In general, all personnel should be guided by all the basic rules of safety associated with theequipment and the process.

1.3 CONSTRUCTIONThe Type “A” pumps are horizontally mounted, vertically split, back-pullout, single-stage, single-suction overhung process pumps designed for continuous duty service in all process industries andindustrial applications within its pressure and temperature limitations.

1.3.1 CASINGThe casing is centerline supported with end suction and top discharge. It provides for the immediatecontainment of the liquid being pumped as the liquid is directed from the suction nozzle through theimpeller and then through the volute to the discharge nozzle. The casing also provides the centerlineattachment to the baseplate or support. A wear ring is mounted in the casing to provide a closerunning tolerance with the impeller wear ring.

1.3.2 IMPELLERThe impeller is a single-suction, radial-flow, closed design which is precision cast to ensure thehighest attainable efficiencies. The impeller is dynamically balanced, keyed to the shaft, and securedby a cap screw and tab washer. Renewable wear rings are press fit on the impeller and secured withradial set screws.

1.3.3 STUFFING BOXESThe stuffing box is either cooled or non-cooled, depending on service requirements. The stuffing boxcontains a stuffing box bushing and provides containment of a mechanical seal or packing. A wearring is mounted in the stuffing box to provide a close running clearance with the impeller wear ring.

1.3.4 SHAFTThe high-strength shaft is of stiff-shaft design, ground over its entire length for close tolerances. Theshaft transmits the required power without vibration.

1.3.5 BEARING HOUSINGThe bearing housing is air-cooled with fan-type flingers provided at the inboard and outboard ends.The bearing housing contains the thrust and radial ball bearings, and serves as the oil reservoir for thebearing lubricating oil, A “Trico”-type oiler is provided for maintaining the required oil level.Labyrinth-type flingers help to seal the bearing housing to prevent contamination of the lubricatingoil.

A finned cooling insert is available as an option for the lubricating oil. Provisions for purge oil mist,pure oil mist, and grease lubrication are also optional.

1.3.6 BEARINGSThe heavy-duty, oversize, single-row radial bearing and duplex angular-contact thrust bearing ensurelong life under the most severe operating conditions. The bearings are a slight press fit in the bearinghousing and on the shaft. Lubrication of the bearings is provided by oil rings.

2. RECEIVING AND STORAGE

2.1 RECEIPT INSPECTIONYour pump was carefully checked at the factory prior to shipment to ensure compliance with therequirements of your order. It is suggested that the pump be inspected upon arrival. As a minimum,the following items should be checked:

1. Inspect the shipping containers for damage or moisture. The condition of the skid and covering isindicative as to the way the shipment was handled. Broken skids, torn coverings, bend hold-downbolts, broken straps, etc., indicate rough handling.

2. Remove the shipping enclosure and visually inspect all pump components for damage.

3. Inspect the preservative coating on various parts. If necessary, renew preservative in areas whereit has been rubbed or scraped.

4. Inspect all painted surfaces. If necessary, touch up the areas where paint has been chipped orscraped.

5. Inspect all covers over pump openings and piping connections. If covers or seals for the coversare damaged or loose, they are to be removed, and a visual inspection made of the accessibleinterior areas for accumulation of foreign materials or water. If necessary, clean and preserve theinterior parts as noted above to restore the parts to the as-shipped condition. Install or replacecovers and fasten securely.

6. The shipping papers should be checked to determine satisfactory arrival of any special tools,loose parts, and/or spare parts (if provided), which are usually preserved and packed in a boxattached to the skid.

If any damage is indicated and/or parts are missing, notify the carrier and the nearest Ingersoll-Dresser Pump office immediately.

Upon conclusion of the receipt inspection, the shipping enclosure should be resealed for storage ortransport.

2.3 STORAGE

NOTE

Unless otherwise agreed, full responsibility and costassociated with the storage and inspection of this equipmentrests with the purchaser.

During extended periods of storage prior to installation, precautions must be taken to protect thepump from deterioration. The various parts of the pump are protected prior to shipment by applyingvarying grades of preservative to the parts. However, during shipment and handling the preservativesare subjected to conditions that can cause their removal. Also, during extended periods of time thepreservatives may deteriorate. The listed procedures should be followed to prevent deterioration ofthe pump during the extended storage period. These procedures may also be supplemented by theexperience of the person performing the tasks.

2.3.1 PREPARATION FOR STORAGEInspect the preservative coating on the various parts. If necessary, renew the preservative in areaswhere it has been rubbed or scraped off. Internal parts of the pump are protected with a petroleum-based rust preventative. External surfaces of parts that are required to be kept free of paint are coatedwith a petroleum-based rust preventative.

Inspect all painted surfaces. If necessary, touch-up areas where paint has been chipped or scraped.External surfaces are usually painted with a paint that combines a primer with a finish coat. See thecontract specification for any non-standard paint requirements, or contact your nearest Ingersoll-Dresser Pump office.

Inspect all covers over pump openings and piping connections. If the covers or seals for the coversare loose or damaged, remove them and visually inspect the accessible interior areas for accumulationof foreign matter and/or water. If necessary, clean and re-coat the interior parts with preservative

and/or paint to restore the parts to the as-shipped condition. Install or replace the covers and fastensecurely.

If the pump was shipped in a sealed plastic covering, then the covering should be reinstalled prior toplacing the pump in storage.

2.3.2 STORAGE AREAIf at all possible, the pump and its component parts should be stored indoors where they will beprotected from the elements. In no case should any pump element be subjected to extended periods ofsubmergence or wetting prior to start up. If it is not possible to store the pump and its componentsindoors, precautions must be taken to protect them from the elements. Regardless of whether storageis indoors or outside, the storage area should be vibration free. All boxes marked for indoor storagemust be stored indoors. When stored outdoors the pump and its components should be protected fromdirt, dust, rain, snow, or other unfavorable conditions by heavy plastic sheets, canvas, waterproofburlap or other suitable coverings.

All equipment must be placed upon skids or blocks to prevent contact with the ground and surfacecontaminants. Equipment must be adequately supported to prevent distortion and bending.

When selecting a storage area, it should be taken into consideration that the deterioration of theequipment and the expenses involved in restoring the equipment at the time of installation will beproportionate to the class of storage provided.

2.3.3 INSPECTION AND MAINTENANCEThe responsibility for setting up an inspection schedule rests with the purchaser and will bedependent upon the class of storage provided. Initially, inspection would occur weekly. Then,depending upon the conditions encountered in the inspection reports, inspection should continueweekly, monthly, or quarterly.

Each inspection should include the following steps, as a minimum:

1. Check that the pump supports are firmly in place.

2. Ensure that the nozzle coverings are firmly in place. Periodically (i.e., every third inspection)remove covers and visually inspect the accessible interior areas. If surface rusting hasoccurred, clean and repaint or re-coat with preservatives. Replace covers.

3. Check that the pump covering (i.e., plastic or tarps) is firmly in place. Any holes or tears mustbe repaired to prevent entrance of dirt or water.

4. Check for any corrosion of the exterior surfaces. If rusting has occurred, clean and repaint orre-coat with preservative.

5. Loosen casing drain plugs to allow seepage of any accumulated moisture.

6. Inspect individually wrapped parts for signs of deterioration. If necessary, renew preservativeand/or wrapping.

7. Document the results of the inspection and keep on file for later review.

3. INSTALLATION

3.1 FOUNDATION AND PIPING

3.1.1 LOCATIONThe unit should be installed close to the source of the liquid to be pumped. The location must alsoallow adequate space for operation as well as for maintenance operations involving dismantling andinspection of parts. Head room is an important consideration because an overhead lift of some type isrequired for assembly and disassembly of the pump.

3.1.2 PIPINGThese units are furnished for a particular service condition. Changes in the hydraulic system mayaffect performance adversely. This is especially true if the changes reduce the pressure at the suctionor if the liquid temperature is increased. When installing piping, Ingersoll-Dresser Pumprecommends:

1. that as the line is erected, a swab fitting the entire cross section of the pipe be pulled througheach section to assure the removal of scale or other foreign material;

2. that suction and discharge piping should be of ample size, be installed in direct runs, and havea minimum of bends;

3. that a suction pipe equal to or one size larger than the pump suction nozzle is used;

4. that there is a straight length of pipe (approx. 8 to 10 times the pipe diameter) just upstreamof suction nozzle (No double turns);

5. that the piping slopes in the correct direction;

6. that no high spots or pockets are present in which air or vapor can collect;

7. that piping supports, valves, and fittings are properly located, and all eccentric reducers orincreasers are properly installed;

8. that the piping is installed to avoid excessive loads on the pump nozzles from poor alignmentof piping or improper location of piping anchors;

9. that a check valve and a gate valve be installed in the discharge pipe of the pump. When thepump is stopped, the check valve will protect the pump against excessive pressure and willprevent the pump from running backward. The check valve should be installed between thegate valve and the pump nozzle in order to permit its inspection.

10. that a spool piece is installed in the suction line so that the suction strainer may be installedand removed with a pressure gauge between the strainer and pump.

3.1.2.1 Suction Strainer

In a new installation, great care should be taken to prevent dirt, scale, welding beads and other itemsfrom entering the pump, as it is particularly important to protect the numerous close running fits fromabrasive matter present in new piping

The suction system should be thoroughly flushed before installing the suction strainer and connectingthe suction piping to the pump.

Page 18: A PUMP INSTALLATION OPERATION & MAINTENANCE · are intended to emphasize certain areas in the interest of operator safety and satisfactory pump operation/maintenance. The ... A procedure

A PUMP INSTALLATION, OPERATION, AND MAINTENANCE

DO2664-07 3-2

The suction strainer should be installed between 5 to 20 pipe diameters upstream from the pumpsuction flange.

The Ingersoll-Dresser standard for suction strainers consists of a conical shaped steel plate. The platehas 1/16” perforations and is of sufficient size and thickness for the required flow. The open area ofthe strainer should have a minimum of a 3 to 1 ratio to the area of the pump suction (see Figure 3-1below).

Preferred Directionof Flow

Cone Type Strainer

Figure 3-1 Typical Suction Strainer

Pressure gauges should be installed on both sides of the screen so that the pressure drop across thescreen can be measured.

When the unit is being started, the gauges on each side of the screen should be carefully watched. Anincrease in the differential pressure between the two gauges indicates that the screen is becomingclogged with dirt and scale. At this point, the pump should be shut down, and the screen cleanedand/or replaced.

3.1.2.2 Bypass Line

Operation at low flows results in pump horsepower heating the liquid. A bypass may be required toprevent vaporization and subsequent pump damage. Refer to your local Ingersoll-Dresser Pumpsoffice to determine if a bypass is required. Mechanical damage may result from continuous operationat flows less than specified.

3.1.3 FOUNDATIONThe foundation should be sufficiently rigid and substantial to prevent any pump vibration and topermanently support the baseplate at all points. The most satisfactory foundations are made ofreinforced concrete. These should be poured well in advance of the installation to allow sufficienttime for drying and curing. A rough finish top surface is best when applying grout.

The General Arrangement Drawing (In the back of this manual) will furnish anchor bolt locations,size of bolts, etc. See Figure 3-2 below.

Figure 3-3 below illustrates the recommended foundation bolt arrangement. Notice the large washerwith lugs at the bottom. It should be welded to the bolt and pipe sleeve to prevent turning.

Allow a little more than the specified threaded bolt length above the rail of the baseplate. The excesscan always be cut off if it is not needed.

Prepare sufficient steel blocks of at least 1 in. (25 mm) thickness to be placed below each baseplatejacking screw furnished with the baseplate. The purpose of the plate is to spread the load of the screwwithout crushing the concrete below, and to provide a minimum of 1 in. (25 mm) grouting spacebelow the baseplate.

Before leveling the baseplate, loosen the pump hold down bolts to eliminate any baseplate distortion.

The baseplate may be leveled using either the installed jacking screws, or using shims, or wedges asillustrated in Figure 3-4 below.

Figure 3-4 Leveling Baseplate With Wedges

Level the baseplate by using a machinist’s level on the machined surfaces of the pump and driverpads. Adjust the baseplate level by adjusting the leveling screws, or by adjusting the shim packsunder the baseplate.

To adjust the shim pack thickness, carefully raise the baseplate by using either the baseplate jackingscrews provided or by levering with a suitable pinch bar or by installing a low level hydraulic jack.Adjust the shim pack thickness and lower the baseplate.

Repeat this procedure in a logical manner at each bolt position until the baseplate is level. Thebaseplate must be level within 0.002 in. per ft. (0.17 mm per m).

When the baseplate is level, pull down the foundation bolts so they are snug. This may disturb thebaseplate, so re-check the levels.

CAUTION

Before grouting, perform a rough shaft alignment. Finalalignment will not be possible if this initial shaft alignmentis not satisfactorily completed prior to grouting thebaseplate.

3.1.5 GROUTING

NOTE

The foundation must be allowed to cure for at least 7 daysbefore grouting the baseplate.

Build a dam around the foundation as shown in Figure 3-5 after leveling the baseplate. If wedgeswere used to level the baseplate, it is a matter of local policy whether the wedges should be removedafter grouting. If you wish to remove the wedges, carefully mark their locations before pouring grout.

Finished Grout

Leave top of foundation rough,do not finish with trowel.

Dam Concrete

Grouting 1 to 2inches deep

Figure 3-5 Grouting Baseplate

Use a good, high strength, non-shrink grout mix and install in accordance with the manufacturer’sinstructions.

Holes are provided in the baseplate to permit pouring the grout and to act as air vents. Fill under thebaseplate completely, stirring to assure correct distribution of the grout. Check to see that the groutflows under the edges of the baseplate evenly. Make sure the baseplate is vented correctly and allareas are thoroughly filled to prevent any resonant problems. Pour grout until level reaches top ofdam. Allow to dry sufficiently to prevent grout from overflowing while completing the remaininggrouting.

NOTE

Do not vibrate baseplate when grouting.

When the grout is thoroughly hardened, remove the dam. If the leveling wedges are removed, fill theholes they leave with grout.

3.2 SHAFT ALIGNMENTShaft alignment is critical to good performance of your pump. Should you require assistance withalignment of your pump and driver contact Ingersoll-Dresser Pumps for a service representative.

Page 22: A PUMP INSTALLATION OPERATION & MAINTENANCE · are intended to emphasize certain areas in the interest of operator safety and satisfactory pump operation/maintenance. The ... A procedure

A PUMP INSTALLATION, OPERATION, AND MAINTENANCE

DO2664-07 3-6

NOTE

Ingersoll-Dresser Pumps recommends the use of either adouble-dial indicator procedure as outlined below or a laseralignment procedure for coupling of this pump. If a laseralignment procedure is used, follow the procedures suppliedby the laser alignment equipment manufacturer foralignment of the pump.

All adjustments during alignment should be made to the driver; the pump should be fixed in positionon the baseplate. To emphasize the importance of this procedure, driver mount pads are machined lowon the baseplate making it necessary to shim under the driver feet in order to raise the driver shafteven with the pump shaft. The following coupling procedures have been planned to ensure that bothshafts are correctly aligned and coupled for extended operation.

3.2.1 ALIGNMENT FREQUENCYTo ensure that the pump and driver are in accurate alignment, their shafts must be checked foralignment and corrected, if necessary, under these circumstances:

1. after connecting the plant piping to the pump;

2. after the first run, with the pump still hot from several hours of operation, with incomingliquid at its normal temperature, and before the pump goes on line for an extended period.

3. after the first slight increase in vibration appears following a long period in service or after asudden increase in vibration.

3.2.2 ALIGNMENT PRECONDITIONSTo simplify shaft alignment and prevent inaccuracy, ensure that the following steps are taken beforeperforming shaft alignment:

1. Ensure that pump hold down bolts are tight.

2. Do not connect suction and discharge piping to pump until after completion of initial coldalignment.

3. Ensure that pads on baseplate and driver feet are thoroughly cleaned.

3.2.3 SETTING MOTOR SHAFT END SPACE

NOTE

If driver is motor with sleeve bearings, begin at step 1. Ifdriver is motor with ball bearings or steam turbine, begin atstep 3.

To prevent destruction of motor sleeve bearings, which are usually found in heavy-duty electricmotors, locate your motor in relation to the pump so as to ensure a running clearance of 0.13 in (3mm) between the thrust collar on the motor shaft and the face of the bearings (see Figure 3-6). Toestablish the required end space proceed as follows:

Figure 3-6 Motor Shaft Running Clearance

1. Set motor on driver pads.

2. If the motor manufacturer has provided information on setting shaft end space in their manualin the back of this manual, use those instructions to set the motor shaft end space. If not, thenset motor shaft end space as follows:

a. Push shaft into motor case until thrust collar butts against face of bearing as shown byFigure 3-6; then select a reference point on motor case and mark shaft with pencil.

b. Pull shaft out away from bearing face (that is, toward pump) as far as it will go; thenusing the same reference point that was selected in step a, mark shaft with pencil.

c. Measure distance between pencil marks; the distance (or total lateral movement) shouldbe at least 0.5 in (13 mm).

d. Set end space by pushing shaft back in toward sleeve bearing 0.13 in (3 mm) (see Figure3-6). At this setting, there will be adequate end space between thrust collars and bearingfaces. For example, if total lateral movement is 0.5 in (13 mm) and the shaft is pushedback in toward bearing face 0.13 in (3 mm) as described, the end space or clearance is0.13 in (3 mm) on the drive end and 0.37 in (10 mm) on the opposite end; 0.5 in minus0.13 in equals 0.37 in.

CAUTION

After setting end space the motor shaft must not be movedprior to scribing location of hold down bolts.

3. Set driver so that distance between ends of driver and pump shafts is as specified by theGeneral Arrangement drawing. Also, if you have a gear-type coupling verify that dimensionD equals dimension L as shown by Figure 3-7; buttons as shown in figure are not installed onspacer where couplings are the diaphragm or disk type.

4. If hold down bolt holes have not been tapped in driver mount pads, you should now proceedwith task (see paragraph 3.2.4 below); otherwise, you may begin cold alignment (seeparagraph 3.2.5 below).

3.2.4 TAPPING DRIVER MOUNT PADSWhere driver mount pads have not been tapped for hold down bolts, they must be tapped beforeattempting to align driver to pump. Proceed as follows:

1. Bolt dial indicator bracket to driver half-coupling or driver shaft as shown in Figure 3-8.

2. Set the bracket to the horizontal (9 o'clock) position. Zero the indicator, then rotate bothshafts 180° to the 3 o'clock position; total indicator reading (TIR) in horizontal plane(between 9 o'clock and 3 o'clock points) shall not exceed 0.002 in (0.05 mm). If TIR isexcessive:

a. hold distance between half-couplings and move driver frame to correct alignment inhorizontal plane;

b. again rotate shafts and check readings;

c. repeat steps a and b until 0.002 in (0.05 mm) TIR in horizontal plane is not exceeded.

3. Reverse position of dial indicator and bracket and repeat step 2.

4. Remove dial indicator and bracket.

5. Scribe location of hold down bolts on mounting pads, then remove driver from pad.

6. Drill and tap hold down bolt holes.

3.2.5 COLD ALIGNMENT

CAUTION

Since an accurate cold alignment is dependent upon bothpump and motor being at ambient temperature, circulatingoil (if applicable) must also be at ambient temperature.

The term "cold alignment" refers to the alignment of pump and driver when they are at, or near,ambient temperature. Since thermal growth affects their alignment, cold alignment should beconsidered a preliminary task that must be performed diligently before the pump is operated for thefirst time. To bring the motor shaft in cold alignment with pump shaft, proceed as follows:

1. Verify that the requirements of paragraphs 3.2.2, 3.2.3, and 3.2.4 have been satisfied.

2. Attach lifting equipment to driver and set it on its mount pads.

3. Check both pump and driver for soft foot at each hold down bolt as follows:

a. Tighten all hold down bolts to the torque recommended by the equipment manufacturer.

b. Install a dial indicator to read the vertical motion of a equipment foot. Loosen the holddown bolt for that foot until it is finger tight. The vertical motion should not exceed 0.002in. (0.05 mm). If the vertical motion is excessive, correct it as follows:

1) Loosen all hold down bolts for that piece of equipment.

2) Lift the equipment and place a shim of a thickness equal to the vertical motion of thefoot must be added underneath the soft foot.

3) Re-torque all hold down bolts to the recommended torque and perform the soft footcheck on that equipment again.

If the vertical motion is within specification, then re-torque the hold down bolt to therecommended torque.

c. Repeat step b. for all remaining equipment feet on the baseplate.

4. Check hubs for run out or possible bent shaft conditions and correct, if necessary, beforeproceeding with alignment.

CAUTION

When using a double indicator setup, each bracket must bechecked for bar sag. Do not assume that similar bracketshave identical sag.

5. Determine the distance from the bracket mounting point to the indicator reading point.

7. Hold the pipe with the indicator facing up and set at "0". Without touching bracket, rotate thepipe 180° so that the indicator is facing down. Read the indicator and record the reading. Thisis the amount of bar sag.

8. Rotate the pipe again so that indicator is facing up. It must return to "0".

9. Repeat steps 7 and 8 to confirm reading.

NOTE

All indicator readings must be taken on the periphery or rimof the coupling hub or shaft, or on the opposite bracket.They must be recorded as viewed from the fixed unit (pump).(see Figure 3-10).

NOTE

Use of a shaft alignment graph, such as Ingersoll-DresserPump Shaft Alignment Calculator (see Figure 3-11) aids andsimplifies the alignment process. It graphically shows theposition of the shaft centerlines in both the vertical andhorizontal planes, the shims to be added or removed, and/orhorizontal corrections to be made for accurate alignment.Further information may be obtained through the Ingersoll-Dresser Pump Service Department.

20. Tighten hold down bolts, then repeat steps 11 through 19.

21. Remove dial indicators and brackets and detach lifting equipment.

22. See paragraph 3.1.2, “Piping”, on page 3-3, and connect piping, as required.

23. Repeat steps 10 through 18 above and record readings. If TIR at either position of dialindicator exceeds 0.002 in (0.05 mm), correct distortion caused by piping, and recheckalignment; pump, piping, and driver must be secured in correct alignment before proceedingwith hot alignment.

NOTE

Steps 24 and 26 apply only if your coupling is the gear type.

24. Install flat strap across hub of driver half-coupling by bolting to flange in two places.

NOTE

Unless hub is strapped down, it will vibrate when the motoris started in step 24.

25. Briefly operate driver in accordance with manufacturer's instructions and observe rotation ofshaft; its rotation must correspond to the direction in which the pump is designed to turn.

26. Remove flat strap.

27. Secure coupling spacer between half-couplings, if not done previously.

28. Install coupling guard.

3.2.6 HOT ALIGNMENT

CAUTION

Gear-type couplings must be lubricated before running pump(see coupling manufacturer's instructions).

After completing a cold alignment of driver and pump, but before the pump is allowed to operate foran extended period, the pump must be operated for a short period until it reaches normal operatingtemperature (see paragraphs 4.4.3 and 4.4.5), then shutdown (see paragraph 4.4.6). Check thealignment immediately after shutdown (ideally, within 10-15 minutes) in order to determine whetherthe centerlines of the driver and pump shafts coincide when both units are hot. This coincidence isnecessary to assure efficient extended operation of the pump. Requirements for a hot alignment checkare:

1. Remove coupling guard.

2. Complete steps 10 through 18 of paragraph 3.2.5 starting on page 3-3 above.

NOTE

TIR in either the vertical or horizontal plane shall notexceed 0.002 in (0.05 mm). Readings on opposite sides must

be opposite signs. Total angularity must not exceed 0.001inch per 12 inches (0.03 mm per 305 mm).

3. Check hold down bolt positions on the graph or otherwise determine the amount of shims tobe added or subtracted for the vertical correction, and the movement required for thehorizontal correction. If maximums are exceeded in this hot alignment:

a. allow units to cool down;

b. complete steps 19a through 19e, 20, and 21 of paragraph 3.2.5 starting on page 3-3above;

c. repeat hot alignment procedure until TIR is within specifications.

4. OPERATION

4.1 TECHNICAL DATAThese pumps are furnished for a particular service condition. Changes in the hydraulic system mayaffect the pump’s performance adversely. This is especially true if the changes reduce the pressure atthe suction flange or if the liquid temperature is increased. In case of doubt, contact the nearestIngersoll-Dresser office.

4.1.1 EFFECTS OF SPECIFIC GRAVITYThe capacity and total head in feet of liquid developed by a centrifugal pump are fixed for every pointon the curve and are always the same speed. Neither capacity not total head will be affected by achange in the specific gravity of the liquid pumped. However, since the developed gauge pressure andthe power required to drive the pump are a function of the specific gravity of the liquid, both will beaffected in direct proportion by any change in the specific gravity. Therefore, a change in specificgravity will affect the discharge gauge pressure. Any changes should be noted, in that they mayoverload the pump’s driver.

4.1.2 EFFECTS OF VISCOSITYThe pump is designed to deliver rated capacity and rated head for a liquid with a particular viscosity.

When contemplating operation at some viscosity other than for which the pump was originallydesigned and/or applied, the changed conditions should be referred to Ingersoll-Dresser for ourrecommendations.

4.1.3 CHANGING THE PUMP SPEEDChanging the speed of a centrifugal pump changes the capacity, total head and brake horsepower. Thecapacity will vary in a direct ratio with the speed, whereas, the total head will vary as the square ofthe speed The brake horsepower will vary in the ratio of the speed cubed except in cases where thespeed change also changes the efficiency of the pump. When contemplating speeds other than of theoriginal condition, refer to Ingersoll-Dresser for recommendations.

4.1.4 NET POSITIVE SUCTION HEAD (NPSH)Any liquid, hot or cold, must be pushed into the impeller of the pump by absolute pressure, such asthe atmospheric or vessel pressure from which the pump takes its suction.

The head in feet of liquid necessary to push the required flow into the pump is called the Net PositiveSuction Head. This value, more commonly called NPSH, is measured above the vapor pressure of theliquid at the pumping temperature.

There are two kinds of NPSH: the NPSHR is the head required by the pump to cover the losses in thepump section - that is shown on the pump characteristic curve. The second, NPSHA, is the headavailable in the system, taking into account friction loss in suction piping, valves, fittings etc. In allcases the NPSHA, measured above vapor pressure, must exceed the NPSHR in order to push theliquid into the pump. Failure to have this will result in both bad performance and mechanical damageto the pump, and in certain cases actual pump failure.

In many cases, this is not a problem because the system is operating within its own flow range toassure product delivery. A simple high pressure alarm, shut down and/or bypass control can be used.However, in systems where product demand has high swings or where more than 100% capacity unitsare desired to support a product system, additional care must be taken.

4.2.2 THERMAL CONTROLThe actual protection of the given unit is best provided by thermal sensors which read direct or“related to” fluid temperatures and respond accordingly by opening additional flow paths until thegiven unit re-establishes the acceptable temperature rise, and sets off alarms if not achieved withinreasonable/normal time periods. (High limit could actually shut down unit).

4.2.3 PRESSURE AND/OR FLOW CONTROLPressure and/or flow sensors can be used to hold the unit at higher flows by opening additional flowpaths once a “high pressure limit” or “ low pressure limit” was indicated. Upon system reachingincreased flow a “low pressure limit” or “high pressure limit” setting would close the bypass flowpath. Care must be taken to allow for signal spread to avoid cyclic conditions.

4.2.4 CONTINUOUS BYPASS CONTROLThis is not a desired system, as it requires an oversize bypass system as dictated below with excessivepower losses and oversize pumping units, however, if used the following must be considered.

4.2.4.1 Continuous Bypass Sizing for Parallel Units

The limits and/or protection requirements of two or more units in parallel operation is dictated by theminimum flow of each particular unit and the performance tolerances of the pump and system.

The following is required to provide unit protection.

1. Determine the minimum flow of one of the units. This will be the smallest flow allowed forany of the units in the parallel system.

2. By general specification, while the rated head condition has a tolerance of +2% to -2% at theguarantee point, the tolerance at “shutoff” (low flow = 0) is +5% to -5%.

Therefore: draw two head capacity curves; one at -2% head at rated capacity and fared to -5%at shutoff, the other at 2% head at rated capacity fared to +5% at shutoff.

The lower curve represents the “weakest” pump in the system and the upper represents the“strongest” pump or pumps in the system.

At the minimum flow from step 1 above, find the Total Developed Head (TDH) of theWeakest pump. Draw a straight line at this TDH until it intersects the head-capacity curve ofthe strongest pump. Read the corresponding “Strong Pump Flow”.

The minimum flow of the pumps within the system can now be defined and provisions must be madein the system to assure the total capacity is not less than this.

4.3.1 LUBRICATION SPECIFICATIONSThe ideal bearing lubricant is mineral oil, preferably of the turbine type. It should be corrosion,oxidation, and foam inhibited, and should not contain free acid, chlorine sulfur or more than a trace offree alkali. It is suggested that the oil conform to the following physical characteristics.

Oil Characteristics Napthene Base Paraffin BaseFlash Point 300°F (149°C) Min. 360°F (183°C) Min.Saybolt Viscosity at100°F (38°C)

150 to 200 Seconds 140 to 185 Seconds

4.3.1.1 Synthetic Lubricants

If a synthetic lubricant (fire-resistant fluid) is to be used instead of the normal type oil for thelubrication of bearings, gears etc., the material of all gaskets and O-rings in contact with the lubricantmust be compatible with the lubricant. Normal gasket materials will usually swell and deterioratewhen immersed in synthetic lubricants, and normal paints will peel from internal walls of reservoirsand bearing chambers.

4.3.2 BEARING HOUSING PREPARATIONBefore filling the bearing housing reservoir, flush out the housing thoroughly with safety solvent anda leading grade of flushing oil, compatible with the lubricating oil that will be used.

4.3.3 OILER ADJUSTMENTSee Figure 4-4 below.

Fill the bearing housing via the housing vent, using the overflow plug to establish the correct level.

Release the thumb screw and remove the reservoir. Position the adjusting nut so that the rim of thereservoir is 0.86 to 0.90 in. (21.8 to 22.8 mm) above the centerline of the side port.

Fill reservoir with recommended oil and install on oiler body. Remove, fill, and reinstall reservoir asmany times as required to fill the bearing housing up to the rim of the reservoir with no air bubbles inthe reservoir.

Remove reservoir and ensure that the oil level is 0.86 to 0.90 in. (21.8 to 22.8 mm) above thecenterline of the side port. Adjust adjusting nut as required and lock in place with lock nut.

4.3.4 INSPECTIONInspect the oil level in the bearing housing at least once a day. Inspect the condition of the oil at leastweekly. Oil is always subject to gradual deterioration from use and contamination from dirt andmoisture which is the cause of premature bearing wear.

4.3.5 REPLENISHMENTReplenish the oil in the oiler as required. More frequent replenishment at high temperatures may berequired.

When in the vicinity of toxic liquids or vapors, wearbreathing protection which is compliant with yourorganization’s local safety procedures.

Page 38: A PUMP INSTALLATION OPERATION & MAINTENANCE · are intended to emphasize certain areas in the interest of operator safety and satisfactory pump operation/maintenance. The ... A procedure

A PUMP INSTALLATION, OPERATION, AND MAINTENANCE

DO2664-07 4-8

Do not allow sparking, flames, or hot surfaces in thevicinity of equipment which handles volatile orflammable liquids.

Do not perform any maintenance on or around the pumpwhen it is rotating.

If unusual noise or vibrations occur, secure the pump assoon as possible.

1. Never operate the pump with the suction valve closed.

2. Never operate the pump with the discharge valve closed.

3. Never operate the pump unless it is completely filled with liquid and vented.

4. Never operate the pump unless an adequate liquid source is available.

5. Never operate the pump on liquids other than the one specified on the pump data sheet.

4.4.2 PRE-OPERATIONAL CHECKSThe following steps should be followed at initial start up and after the equipment has beenoverhauled:

1. Prior to installing the pump, flush the suction side of the system to remove all deposit (slag,bolts etc.).

2. Ensure the pump and piping is clean. Before placing the pump in operation, the piping shouldbe thoroughly back flushed to remove any foreign matter which may have accumulatedduring installation.

3. Install the suction strainer (see paragraph 3.1.2.1, “Suction Strainer”, on page 3-3).

4. Fill the bearing housing with the appropriate oil to the correct level in accordance withsection 4.3, “Lubrication”, on page 4-3. The bearings must receive a small amount of oil priorto starting to ensure adequate lubrication at start-up.

5. Turn pump rotor by hand or with a strap wrench to ensure it turns smoothly.

6. Ensure that the correct seal piping has been installed and that it is undamaged.

7. Ensure coupling is correctly aligned and lubricated, and pump and driver is satisfactorilydoweled (see paragraph 3.2, “Shaft Alignment”, on page 3-3).

8. Ensure coupling guard is correctly installed.

WARNINGThe unit must not be operated unless coupling guard issecurely and completely bolted in place.

9. Check torque of all bolting and plugs for tightness.

4-9 DO2664-07

4.4.3 INITIAL START UP PROCEDURE1. Close discharge valve if valve is not already closed, and then crack it open to ensure minimal

flow. (Do not start pump with a fully closed discharge valve). On first starts care must betaken not to cause a system water hammer.

2. Prepare the driver for start up in accordance with the driver manufacturer’s instructions.

3. Check the oil level in the bearing housing to ensure sufficient oil is available for bearinglubrication. Replenish oil as necessary in accordance with section 4.3, “Lubrication”, on page4-3. Also ensure that bearing housing oil temperature is greater than 60°F (15.6°C).

4. Warm up pump.

The pump must be preheated prior to start up to avoid severe thermal shocks to the pump as theresult of sudden liquid temperature changes. Unless otherwise specified, the temperature ofthe casing must be within 100°F (55°C) of the temperature of the liquid to be pumped at timeof start up. Due to the heavy metal sections, the casing temperature will lag the liquidtemperature during such changes, and severe thermal stresses and subsequent misalignmentof machined fits may result. Preheating is accomplished by circulating a small amount of hotfluid through the casing by utilizing vents, drains or bypass from discharge. Preheat pumpslowly at a rate not to exceed 50°F (28C) per hour.

5. Prime pump and ensure suction valve is open.

CAUTION

Before starting or while operating the pump, the casing andsuction line must be completely filled with the liquid beingpumped. The rotating parts depend on this liquid forlubrication and the pump may seize if operated withoutliquid.

6. Ensure pump recirculation line (if required) is open, clear and free of obstructions.

WARNINGWhen venting or draining any vessel which containstoxic, flammable, or otherwise hazardous fluids, ensurethat the vented or drained fluid is piped to a safecollector which will prevent release of the fluid into thesurrounding area. Do not breath toxic vapors.

7. Check that pump is vented by observing leakage from casing vent (if installed) and sealpiping vent. Close vent when liquid is emitted.

8. Turn on cooling liquid and ensure correct flow exists (to cooler, gland etc.) as specified.

9. Double-check pump rotation by starting unit momentarily. The direction of input shaftrotation is counter clockwise when facing pump shaft from coupling end. Ensure that thepump coasts to a gradual stop.

Page 40: A PUMP INSTALLATION OPERATION & MAINTENANCE · are intended to emphasize certain areas in the interest of operator safety and satisfactory pump operation/maintenance. The ... A procedure

A PUMP INSTALLATION, OPERATION, AND MAINTENANCE

DO2664-07 4-10

CAUTION

If pump stops abruptly when driver is shut down, investigatefor pump binding. Take necessary remedial action beforeresuming operation.

10. Start the driver in accordance with the manufacturer’s instructions and bring it up to speedquickly.

11. As soon as the pump is up to rated speed, slowly open discharge valve. This will avoid abruptchanges in velocity and prevent surging in the suction line.

12. Perform the operating checks outlined in paragraph 4.4.5 below.

13. After unit (particularly units in services 100°F (55°C) or more above ambient) has beenoperated a sufficient length of time to reach normal operating temperature and condition, theunit is to be shut down and a hot alignment check must be performed (see paragraph 3.2.6,“Hot Alignment”, on page 3-3).

4.4.4 NORMAL START-UPThe starting procedure to be followed for normal start-up is the same as that for initial starting withthe following exceptions:

1. The rotation check of step 9 does not have to be repeated if the pump driver has not beendisturbed since the last pump operation.

2. The hot alignment check of step 13 does not have to be performed if the pump coupling hasnot been disturbed since the last pump operation.

4.4.5 OPERATING CHECKS

WARNINGIn the interest of operator safety the unit must not beoperated above the nameplate conditions. Suchoperations could result in unit failure causing injury tooperating personnel. Consult instruction book for correctoperation and maintenance of the pump and itssupporting components.

CAUTION

Operation at low flows results in pump horsepower heatingthe liquid. A bypass may be required to prevent vaporizationand subsequent pump damage. Refer to your local Ingersoll-Dresser Pump office to determine if a bypass is required.Mechanical damage may result from continuous operation atflows less than the specified minimum continuous stableflow.

Immediately after start up, and frequently during running check the following:

Page 41: A PUMP INSTALLATION OPERATION & MAINTENANCE · are intended to emphasize certain areas in the interest of operator safety and satisfactory pump operation/maintenance. The ... A procedure

A PUMP INSTALLATION, OPERATION, AND MAINTENANCE

4-11 DO2664-07

1. Check suction and discharge pressure gauges.

2. Check pressure gauges on each side of suction strainer.

CAUTION

Excessive tightening of the packing gland increases packingwear which in turn is apt to result in burned packing and ascored shaft sleeve.

3. Check for leakage at seal areas. If your pump is equipped with mechanical seals, no leakageshould be evident. If your pump is equipped with packing, then there should be a leakage rateof about 5 to 15 drops per minute from the packing gland. If the packing leakage is not withinspecification, proceed as follows:

a. Shut down the pump. (see paragraph 4.4.6 below).

b. Adjust the torque on the packing gland nuts by one flat tighter if leakage was excessive,or one flat looser if leakage was insufficient.

c. Start up the pump (see paragraph 4.4.4 above).

d. Allow leakage to stabilize and check leakage rate again.

4. Check for unusual noises.

WARNINGOperation of the unit without correct lubrication canresult in overheating of the bearings, bearing failures,pump seizures and actual breakup of the equipmentexposing operating personnel to physical injury.

5. Check oil level in bearing housing.

6. Ensure that the bearing oil temperature is within its normal operating range of 140 to 160°F(60 to 71°C). At no time should the bearing oil temperature exceed 180°F (82°C).

7. Check for adequate flow of cooling liquids.

4.4.6 SECURING THE PUMPThe pump should be shut down rapidly to protect the internal wear parts which are lubricated by theliquid being pumped.

1. Shut down driver in accordance with the manufacturer’s instructions.

CAUTION

If pump stops abruptly when driver is shut down, investigatefor pump binding. Take necessary remedial action beforeresuming operation.

2. Close the pump discharge valve. The pump suction valve should be closed only if required bysystem operation or maintenance.

3. Close valve in bypass line

5. MAINTENANCE

5.1 GENERALAvoid serious or troublesome problems by systematic maintenance checks. Study Table 4-3,“Troubleshooting Table”, as an aid to your maintenance program.

Your pump is a precision machine. Take every precaution to avoid damage or even slight burrs to theshaft bearing areas, as well as any other ground finished surface when dismantling your pump.

It should be understood that the information contained in this manual does not relieve operating andmaintenance personnel of the responsibility of exercising normal good judgment in operation andcare of the pump and its components.

The A pump incorporates a pull-out element design, so it is not necessary to remove the casing,detach the suction or discharge piping, or disturb the driver, in order to perform any regularmaintenance on the pump.

All part numbers referenced in parenthesis below may be indexed to the Pump Assembly drawing orthe Parts List, both located in the back of this manual.

Before performing any disassembly, maintenance and/or inspection on the unit, the following stepsshould be taken:

WARNINGWhen in the vicinity of caustic, corrosive, volatile,flammable, hot, cold, or otherwise hazardous liquids,wear protective clothing which is compliant with yourorganization’s local safety procedures.

When in the vicinity of toxic liquids or vapors, wearbreathing protection which is compliant with yourorganization’s local safety procedures.

Do not allow sparking, flames, or hot surfaces in thevicinity of equipment which handles volatile orflammable liquids.

When venting or draining any vessel which containshazardous fluids, ensure that the vented or drained fluidis piped to a safe collector which will prevent release ofthe fluid into the surrounding area.

Before performing any maintenance on the pump, thedriver controls must be in the OFF position, locked andtagged to prevent operation.

Thoroughly drain and dry the baseplate before anymaintenance is performed on the pump. This will reducethe risk of personnel slipping on a wet surface.

5.4 INSPECTION AND RENEWAL OF PARTSAfter the pump has been disassembled for repair or overhaul, each part should be cleaned andinspected. Any parts deemed unacceptable for further use should be replaced with new parts, unlessotherwise instructed. Detailed instructions are given in the following paragraphs.

5.4.1 CLEANING

WARNINGFumes from alcohol, acetone, petroleum solvents andother such chemicals are injurious to health and mayignite from a spark. Ensure that the area where they areused is well ventilated and has a fire extinguisher nearby.

When the pump is used in a steam or water circuit, all internal parts of the pump should be cleanedwith a non-petroleum-based cleaning agent such as alcohol or acetone or a steam cleaner that usessteam from demineralized water. Petroleum-based agents such as dry cleaning solvent or kerosenemay be used for cleaning when the cleaning agent will dissolve in the pumped liquid without illeffect. Petroleum-based agents should be used to clean the bearing housing and associated parts.

5.4.2 INSPECTION OF PARTSThe following parts must be inspected for conditions that can impair pump operation beforereassembling the pump. Unusable parts should be replaced rather than repaired, except as notedbelow. Some items are cross-referenced to a detailed procedure.

1. Inspect all parts for cracks, corrosion, or other damage which could lead to failure of the part.All painted surfaces should be inspected and touched up as necessary.

2. Inspect all abutting machined surfaces, gasket seating surfaces, and O-ring grooves and faces.These surfaces must be perfectly smooth and free of damage, foreign matter, or corrosion.Clean or replace these parts as necessary.

3. Check shaft (1) for straightness (see paragraph 5.4.3, “Checking Shaft Straightness”, below).

4. Inspect impeller (34) for cracks, damage, or erosion. Also check the impeller bore for correctfit with the shaft (see paragraph 5.4.4, “Checking Fit Between Impeller Bore and Shaft”,below). If eroded or damaged, the impeller must be repaired or replaced before finalassembly. If the impeller is repaired, it must be dynamically balanced before final assembly.

5. Inspect wearing surfaces of wear rings (26A/B, 200A/B), and stuffing box bushing (0162) fordamage, scouring, or erosion. Also check running clearances of these parts (see paragraph5.4.5, “Checking Running Clearances”, below).

6. The mechanical seal (3213A) should be disassembled and inspected in accordance with themanufacturer’s instructions located in the back of this manual. Specifically, the stationary androtating seal faces should be inspected for wear or cracking and replaced as necessary. Whenreassembling the seal, all old gaskets and O-rings should be discarded and replaced with newparts.

5.4.3 CHECKING SHAFT STRAIGHTNESS

CAUTION

Application of heat to straighten shaft will cause moredistortion.

When making the check do not turn the shaft in its lathe centers. It is possible for the lathe centers ofa straight shaft to be off center slightly, resulting in a false indication of a bent shaft. Set shaft in soft-faced V-blocks or precision rollers and check straightness by taking dial indicator readings all alongthe shaft while it is rotated. Total runout of shaft must not exceed 0.0015 in (0.04 mm). If runout isexceeded, the shaft must be cold-straightened or replaced.

5.4.4 CHECKING FIT BETWEEN IMPELLER BORE AND SHAFT

NOTE

A three-point micrometer is the preferred instrument formeasuring bore; a stick micrometer is its alternate. Whenmeasuring with the three-point micrometer, measure close tothe keyway. With stick micrometer, measure three places at120-degree intervals.

The fit between the impeller bore and the shaft must be correct or vibration can occur. To check thefit, use a micrometer to measure diameter of bore under thickest metal near each end of the impellerkeyway and the corresponding diameter of shaft. Then subtract the diameter of the shaft from thediameter of the impeller bore and divide by two to obtain the clearance. The clearance should be0.0005 in (0.013 mm) to 0.0015 (0.04 mm). If this clearance is exceeded, the impeller should bereplaced.

5.4.5 CHECKING RUNNING CLEARANCESRunning clearance is determined by measuring the inside diameter of the stationary part and theoutside diameter of the rotating part, then taking the difference between the correspondingmeasurements and dividing by two to obtain the clearance. Measurements should be taken with amicrometer and each part should be checked for roundness by taking readings 90° apart. These partsshould be replaced when running clearances have increased by 50 to 100% over the design clearanceslisted on the Pump Assembly drawing in the back of this manual. Wear rings should be replaced inaccordance with paragraph 5.4.6 or paragraph 5.4.7 below.

5.4.6 REPLACING STATIONARY WEAR RINGS

NOTE

For replacement of the case wear ring (26A) it isrecommended that the case be removed from the system andtransported to a suitable work area.

To replace a stationary wear ring (26A/B), proceed as follows:

CAUTION

Ensure that the parent part is not damaged during removal ofthe wear ring.

1. Remove the wear ring set screws (82A).

2. Remove the old wear ring by placing the parent part in a lathe and turning out the wear ring.If this is not feasible, grind through the wear ring in two places and break the ring out of theparent part.

CAUTION

Do not bind or distort the wear ring.

Ensure that the temperature of the parent part is above 70°F(21°C) before installing wear ring.

3. Sub-cool the new wear ring in dry ice to shrink it; then, bottom the ring squarely in the boreof the parent part by using an aluminum drift and mallet to strike evenly around thecircumference of the wear ring.

4. Allow the wear ring to return to ambient temperature before proceeding. Do not use anyartificial heat source, such as a torch or heat gun, to warm the wear ring.

5. Verify trueness of the wear-ring-to-part fit as outlined below, or by an equivalent technique:

a. Set up the parent part in a lathe or milling machine so that the register face of the parentpart can be used as a true side for a dial indicator. The centerline of the parent part mustbe aligned with the centerline of the machine's table, and the parent part must be parallelwith table within 0.001 in. (0.03 mm).

b. Set up a dial indicator to run on the inside diameter of the wear ring and rotate the table(or chuck). Total runout must not exceed 0.0015 in (0.04 mm).

6. Install the wear ring set screws (82A).

7. Inspect the wear ring wear surface for damage.

5.4.7 REPLACING IMPELLER WEAR RINGS

NOTE

Whenever an impeller has new wear rings installed, it mustbe dynamically balanced before reassembly.
