INTRODUCTION

SECTION 1

INTRODUCTION a •

This manual contains instructions for installation, operation and mainten-ance of your Ingersoll-Rand Centrifugal Pump. It has been designed to provide safe and reliable service. However, it is both a pressure vessel and a piece of rotating machinery. Therefore, the operator(s) must exercise good judgement and proper safety practices to avoid damage to the equipment and surroundings and prevent personal injury,

r

The instructions in this manual are intended for the guidance of personnel with a general training in operation and maintenance of Centrifugal Pumps. It. is our hope that you will be come acquainted with its content as an aid to better pump performance. This manual should be read in its entirety before installing, and/or operating the equipment. The Assembly Drawings (included in Section 7) and General Arrangement Drawing (included in Section 8) should be consulted for accurate details and determination of specific optional features that are furnished with your pump. All numbers in paren-thesis () following part names correspond with "Exploded View" Noun Codes. EXAMPLE:"T1-003A) - Exploded "View f 1, Noun Code #003A - Impeller Assemb1y. Exploded Views are included in Section 6.

SAFETY

It is assumed that your-safety department has established a safety program based upon a thorough analysis of industrial hazards. Before installing and operating or. performing maintenance on the pump and associated components described in this manual, it is suggested that the safety program be review-ed to ensure that it covers the hazards arising from high speed rotating machinery.

It is .also important that due consideration be given to those hazards which arise from the presence of electrical power, hot oil, high pressure and temperature liquids, toxic liquids and gases and flammable liquids and gase3. Proper installation and .care of protective guards, shutdown devices and over pressure protection equipment should also be considered an essen-tial part of any safety program.

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

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

DESCRIPTION

'The "DAn Pump is a multi-stage, single suction - opposed impeller, horizon-tally split volute pump.

The suction and discharge nozzles are cast integral with the lower half casing,

Rotating parts are accessible by removing the upper half casing which can be removed without breaking suction and discharge piping.

;CASING

The casing provides for immediate containment of the liquid being pumped, while directing the flow of liquid from the suction nozzle to the impellers and subsequently through the volute to the discharge nozzle.

The casing halves, are sealed by the use of a gasket and are joined together by studs, which are installed in the lower half casing and fastened with washers and cap nuts,

IMPELLERS

The Impellers are single suction, enclosed type, one piece construction and are dynamically balanced.

They are fitted with renewable impeller rings (front and back) which are held in place by headless set screws.

The impellers are keyed, have a shrink fit to the pump shaft and are held in axial position by a split ring.

CASING RINGS

Casing rings are positioned over the impeller front rings. These rings are tubular and renewable,

CHANNEL RINGS

Renewable channel rings are positioned over the impeller back rings. They divide the casing into stages. These rings are horizontally split and are held together by dowel pins.

CENTER SLEEVE -

A renewable type center sleeve is used under the center bushing. The center sleeve is tubular and keyed to the shaft (via the impeller key).

CENTER BUSHING

The renewable center bushing is horizontally split, the two halves are held together by socket head capscrews and taper dowel pins. It is held in position by the raised annular ring of the bushing engaging the annular 'groove in the casing.

The center bushing in conjunction with center sleeve divide the casing at the center (back to back) impellers.

THROTTLING SLEEVE

Renewable type throttling sleeve is used under the throttling bushing. The throttling sleeve i3 tubular, keyed, has a shrink fit to the shaft, and are held in position by a split ring.

1-3 If

•THROTTLING BUSHING

Renewable type throttling bushing is used. It is held in position by the annular ring -of the bushing engaging the annular groove in the casing.

The throttling bushing, in conjunction with the throttling sleeve, allows pressure to be blead off thru the balance line, so that pressure on the stuffing boxes is balanced. The throttling bushing also balance the axial thrust of the pump rotor,

SHAFT

The high strength shaft is ground over its entire length to close toler-ances, The shaft is designed to transmit the required power without vibra-tion and is stepped at each impeller fit for ease of assembly and disassem-bly.

. SHAFT SLEEVES.

Renewable shaft sleeves are provided with pumps equipped with packed stuf-fing boxes to protect the shaft at the stuffing box areas. The sleeves are tubular type, keyed to the shaft, and held in position by the retaining ring3,

BEARING LININGS

The bearings are carbon steel backed, babbitt lined, sleeve type insert bearings. The bearing inserts are mounted in the bearing bodies and kept from rotating by means of stop pins. The bearing inserts are renewable.

THRUST BEARING (Refer to Kingsbury Thrust Bearing Drawing) N

The Kingsbury thrust bearing is of the equalizing type having six thrust shoes on each side of the thrust collar and is consequently capable of transmitting the thrust load in either direction. The thrust is transmitted through the thrust collar to the shoes, by the 3hoes to the shoe supporting elements, and thence to the bearing body and the foundation,

STUFFING BOXES

The stuffing boxes are cast integral with the casing. The suction and discharge end stuffing boxes can be equipped with a cartridge type mechani-cal seal or stuffing box packing.

COOLED STUFFING BOX EXTENSION

A cooled stuffing box extension is offered on this type pump as an option. This extension is inserted into the stuffing box and has a cooling jacket through which cooling liquid is circulated.

1-4

CHECK UPON ARRIVAL

Your pump was carefully checked at our shops pri'or to shipment to assure its meeting the requirements of your order.

It is suggested that the pump be inspected upon arrival and that any irregularities arising due to shipping be reported immediately to the carrier.

CARE DURING STORAGE

If it is necessary to store the unit any length of time before installa-tion, find a location where it will be protected from unfavorable weather and is vibration free.

The nozzle covers provided with the unit should be.i"left in place during storage.

Electric motors (pump driver) should not be stored in damp places"without special protection (refer to motor manufacturers instructions).

RUST PREVENTIVE

Internal parts of the .pump and bearing housings are protected prior to shipment with a thin film polar type rust preventive [pump internals (Fer-rocote 5684), bearing housings (MIL—C—16173 Grade 3)3. This can be removed out by flushing with petroleum solvents.

External machined surfaces are protected with durable drying type . rust preventive (MIL-C-16173 Gr ade 1). This can be removed with kerosene or safety solvent (TOWER NO. 392).

External non-machined surfaces are painted with one coat of gray enamel followed by a coat of multi-color speckle lacquer.

Exception: External non-machined surfaces of the pimp (if operating above 200 Degrees F.) are painted with a high temperature aluminum base paint.

Parts on parts orders are protected with a thin film polar type rust preventive, This can be removed with petroleum solvents.

LIFTING EQUIPMENT

.

MAKE SURE THAT ANY EQUIPMENT USED TO LIFT THE PUMP OR ANY OF ITS COMPONENTS IS CAPABLE OF SUPPORTING THE WEIGHTS ENCOUNTERED, MAKE SURE THAT ALL PARTS ARE PROPERLY RIGGED BEFORE ATTEMPTING TO LIFT,

TO LIFT UNIT

pump, driver and bedplate can NOT be lifted as a unit. Driver must be removed from bedplate before lifting.

To lift punp and bedplate or just bedplate, sling bedplate from all lifting eyes. Failure to do this will result in permanent deformation of bedplate,

TO LIFT DRIVER

Refer to .driver manufacturers instructions.

TO LIFT PUMP

Install sling from overhead hoist and under bearing housing mounting brack-ets (cast portion of casing that bearing housings attach).

DO NOT. LIFT ENTIRE PUMP FROM CAST LIFTING LUGS ON UPPER HALF CASINGS. THESE LUGS ARE FOR LIFTING UPPER HALF CASING ONLY.

LOCATION

Inatill th« unit cloae to the souroe of the liquid to be pumped.

When selecting the location, be sure to allow adequate space for opera-tion as well as for maintenance operations involving dismantling and inspection of parts.

Head room is an important consideration as an overhead.lift of some type is required.

The foundation should be sufficiently rigid and substantial to prevent any pump vibration and to permanently support the bedplate at all points.

The most satisfactory foundations are made of reinforced concrete. These should be poured well' in advance of the"installation to allow proper time for drying and curing.

The General Arrangement Drawing will furnish anchor bolt locations, size of bolts, etc.

TEMPLATE FOR HANGING FOUNDATION BOLTS

2-1

The sketch below illustrates a recommended foundation bolt arrangement. Notice the large washer with 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 bedplate. The excess can always be cut off if not needed,

A rough finish top surface is best when applying grout.

INSTALLATION CHECK LIST

1. Level Bedplate

2. Grout Bedplate

3. Align Shaft/Coupling

4 , Piping '

5. Check Coupling Alignment

LEVEL THE BEDPLATE

Before putting the unit on the foundation, thoroughly clean the top of the foundation. Break off any loose pieces of cement and roughen the top with a chisel to afford a good hold for grout.

NOTE

Coupling bolting and spacer piece (when used) must be removed from between pump/driver half couplings before lifting bedplate with pumping element.

NOTE

When lifting bedplate with pumping element, sling bedplate from all lifting eyes provided. Failure to do this may result in permanent deformation of bedplate.

2 - 2 2

Prepare enough iron wedges or shims to be placed on each side of each foundation bolt. These wedges should be about 4 to 6 inches long, 2 to 3 inches wide and thick enough to allow for 1 1/4 inches of grout under the edge of the bedplate. Place wedges as shown in sketch.

Level the bedplate by using a machinist's level on the machined surfaces of the pump and driver pads. When the bedplate is leveled, pull down the foundation bolts so they are 3nug, The bedplate may have been disturbed by tightening down the foundation bolts, therefore, recheck with level and make necessary adjustments by wedges or shimming.

As a final bedplate alignment check on spacer type couplings, install a mounting bracket for dial indicator on driver hub. Fasten or clamp indi-cator on mounting bracket so that dial indicator button is contacting face on pump half coupling and zero the dial indicator, (Non-spacer type coupling should be checked with tappered wedge or feeler gages.)

Rotate the driver half coupling (in direction of pimp rotation) 90 degrees. Record this reading.

Repeat this procedure until readings have been taken at (4) 90 degree positions.

Using this procedure shim and/or wedge bedplate until pump and driver are within ,003 inch.

GROUTING

Build a dam around the foundation. It is a matter of personal preference whether the leveling wedges under the bedplate should be removed after g r o u t i n g . If you do want to remove the wedges, carefully mark their locations before pouring grout.

BUILD DAM AROUND FOUNDATION BEFORE POURING GROUT

Use a quality, high strength, non-shrink grout - mix and install per manu-facturers instructions.

Holes are provided in the bedplate to permit pouring the grout and stir-ring, They also act as air vents. Fill under the bedplate complete-ly, stirring to assure proper distribution of the grout. Check to see that the grout flows under the edges of the bedplate evenly.

NOTE

Do not vibrate bedplate" when grouting, make sure bedplate is vented properly and all areas as indicated on General Arrangement Drawing are thoroughly puddled to prevent any resonant problems.

When the grout is thoroughly hardened, remove the dam and wedges, if desired, filling in the holes they leave with grout.

SHAFT/COUPLING ALIGNMENT

C A U T I O N

SHAFT ALIGNMENT MUST BE CORRECT FOR SUCCESSFUL OPERATION. RAPID WEAR, NOISE, VIBRATION AND ACTUAL DAMAGE TO THE EQUIPMENT MAY BE CAUSED BY SHAFT MISALIGNMENT. THE SHAFTS MUST BE ALIGNED WITHIN THE LIMITS GIVEN.

Adjustment to correct the alignment in one direction nay alter the alignment in another direction. Always check in all directions after making any adjustment.

Coupled equipment must be aligned to minimize unnecessary stresses in shafts, bearings and coupling, Flexible couplings will not compensate for appreciable misalignment. Foundation settling, thermal expansion, nozzle loads resulting in bedplate/foundation deflection and vibration during operation may require the full coupling misalignment capability,

TYPES OF MISALIGNMENT

There are two types of shaft misalignment; angular and offset. Therefore, two sets of measurements and corrections are required. Both types of misalignment can occur in horizontal and vertical planes and are present in most applications.

A, Angular Misalignment

In angular misalignment, the centerline of the shafts intersect, but are not on the same axis.

B. .Offset Misalignment !

In offset misalignment, the shaft centerlines are parallel but do not intersect.

NOTE

ANGULAR MISALIGNMENT

OFFSET MISALIGNMENT COMBINATION OFFSET AND

ALIGNMENT

A. Measure Gap

The first step in shaft/coupling alignment is to bring the pump and driver shafts into their proper axial position. The shaft gap or distance between coupling hubs must be in accordance with the certified General Arrangement Drawing and must be measured with pump and driver shafts in the center of their axial end f1oat. Motor with sleeve bearings are to be aligned with rotor at magnetic center.

Move driver to insure proper gap distance.

NOTE

It is recommended that the pump hold down bolting be torqued and pump be dowelled before taking any alignment measuremets. This makes the pump the fixed machine and the driver the movable machine. In certain cases, how-ever, it may be impractical to move the driver, therefore, the pump may have to be moved. When this case exists, the pump should not be dowelled until after final alignment.

B, Measure Angular Misalignment

Refer to "ALIGNMENT DATA SHEET'1 and examples.

CAUTION

PUMP. SHAFT' SHOULD NOT BE ROTATED MORE THAN 'NECESSARY WHEN ALIGNING SHAFTS, DAMAGE COULD OCCUR TO INTERNAL WEARING PARTS WHICH ARE LUBRICATED BY THE PUMPED LIQUID. ,

The angular misalignment can'best be determined by the use of a hand-held inside micrometer, marked "B" on sketch. All measurements should be taken at the same radial distance from the shaft centerline, as close as possible to the hub outside diameter. The location, of these measurements is defined as the n D" dimension on the "ALIGNMENT DATA SHEET". Do not move the shafts axially while rotating the shafts and taking measurements. Both hubs must be rotated together to cancel possible hub face runout. The relative mea-surement (top minus bottom, right minus left) is the important number.

1. Mark both coupling hubs at 3.6,9 and 12 o'clock positions so they can be rotated together and at 90 Degree intervals.

2. Starting with the 12 o'clock markings of both hubs in the top center position, measure the gap at top, bottom, right and left side. Record these d im en si on s oh "ALIGNMENT DATA SHEET" Sheet 1, Part 1 in the 0 Degree Colunn,

Right side and left side are determined when viewing the driver coupling from the pump.

3. Rotate both shafts 90 degrees in the direction of pump rotation. Measure gap dimensions at the four (4) locations as in Step 2. Record on "ALIGNMENT DATA SHEET" - Sheet 1, Part 1 in the 90 Degree Column.

H. Repeat Step 3 until measurements have been taken at the four (4) 90 Degree po sit ions.(0,90,180. and 270 Degrees),

5» Rotate both shafts to the starting position (12 o'clock markings at top center) and recheck dimension recorded in Step 2.

6. For 0,90,180 and 270 Degree Columns, subtract the bottom from the top and left from right. Record in their respective blocks on Data Sheet. Watch sign notations!

7. Total the different numbers (reading across), divide by 4 and record the average . Record in "Open At " the shaft relative angular

The inside faces of the driver and pump half hubs must be parallel within .001". C. Measure Offset Misalignment

Offset misalignment is measured using a dial indicator on the outside diameter of the coupling hubs and rotating the hubs together to cancel rim surface inaccuracies.

1. ' Starting with the 12 o'clock markings of both hubs on top center, fasten or clamp an indicator on driver hub, marked "A" on sketch, with dial indicator button contacting alignment surface on the pump hub.

*

2. Zero the dial indicator,

3. Rotate both coupling hubs (in the direction of pump rotation) 90 Degrees and take a reading. Record on "ALIGNMENT DATA SHEET" - Sheet 1, Part 2 in the proper right side or left side blank (right or left sides are determined when viewing the driver half coupling from the punp) .

DIAL INDICATORS AT DRIVER FEET

The shims between the equipment feet and mounting surface should be clean and dry. This is especially critical for purcps in service for some time and need to be realigned. Water, dirt and rust may change the height of the shim pack over a period of time. Shims should be made large enough to support the weight of the equipment on its mounting foot. Do not use many thin shims as this may result in a spongy mounting.

Move the equipment vertically by adding or removing the calculated thickness of shims. Torque equipment hold down bolting to required values.

It is recommended, the completed "ALIGNMENT DATA SHEET" be retained as part of your, permanent maintenance file.

CHECK COUPLING ALIGNMENT

The angular and offset coupling alignment must be rechecked.

1. Coupling faces are to be parallel within .001" TIK.

2. Coupling outside diameters are to be aligned within .003" TIR,

3. "Bump" the motor and check motor rotation,

A. Cold Pumps (Below 200 Degrees F.)

Pump hold down bolts are to be. torqued to the proper value and dowel pins are put in two (2) feet (diagonally opposite).

B. Hot Pumps

Pumps handling liquid-s of 200 Degrees F. and over are designed to permit the casing to expand with temperature away from coupling end of pump.

The units that come under this classification must have the pump supports or feet dowelled to the baseplate at the coupling end. This maintains the coupling gap at the desired amount.

SUCTION AND DISCHARGE PIPING

These units are furnished for a particular service condition. Changes in the hydraulic system may affect performance adversely. This is especially true if the changes reduce the pressure at the suction or if the liquid temperature is increased. In case of doubt contact the nearest Ingersoll-Rand Office.

Suction and dischrge piping should be of ample size, be installed in direct runs, and have a minimum of bends,

NOTE

PROVISION. MUST BE MADE TO SUPPORT PIPING EXTERNAL TO THE PUMP TO- PREVENT EXCESSIVE NOZZLE LOADS AND MAINTAIN PUMP-DRIVER ALIGNMENT.

Install a check valve and a gate valve in the discharge pipe on the pump. When the pump is stopped, the check valve will protect the pump against excessive pressure and will prevent the pump from running backward. The check valve should be installed between the gate valve and the pump nozzle in order.to permit its inspection. The gate valve is also useful in priming and starting the pump.

Keep the suction pipe short and direct. Use a suction pipe at least one size larger than the pump suction nozzle. Keep the suction pipe free of all air pockets.

IMPORTANT

A SPOOL PIECE SHOULD BE INSTALLED IN SUCTION LINE'SO THAT THE SUCTION SCREEN MAY BE INSTALLED AND REMOVED.

BY PASS LINE

W A R N I N G

OPERATION AT LOW FLOWS RESULTS IN PUMP HORSEPOWER HEATING THE LIQUID. A BY PASS MAY BE REQUIRED TO PREVENT VAPORIZATION AND SUBSEQUENT PUMP DAMAGE. REFER TO LOCAL INGERSOLL-RAND BRANCH TO DETERMINE IF A BY PASS IS REQUIRED. MECHANICAL DAMAGE MAY RESULT FROM CONTINUOUS OPERATION AT FLOWS LESS THAN 25 PERCENT OF THE DESIGN OPERATING POINT OF THE PUMP. Refer to General Ar-rangement Drawing Notes and nameplate rating.

Customer to install a yarway "ARC" valve (Automatic Recirculation Control), furnished by Ingersoll-Rand Company per drawing 62061460 in discharge line between pump discharge and first valve.

Customer to provide a 1.50" by-pass line from yarway nARC" valve to source of suction. A paddle orifice, furnished by Ingersoll-Rand Company per drawing no. X-150D438JX3,.is to be installed in by-pass line as close to source of suction as possible to prevent vaporization in line.

WARM-UP LINE NOTE

Customer to install 1.00 muffled type orifice furnished by Ingersoll-Rand Company per drawing Y-3HMTA438AX1 in line, by-passing main discharge valve. Direction of flow is from discharge to suction at 20 GPM,

STUFFING BOX

Customer to inject 1/2 GPM cooling water at 10 PSI above suction pressure for each box,

LUBE OIL COOLER

Customer to inject 3,5 GPM of cooling water at 85.Degrees F. and 150 PSI maximum to lube oil cooler inlet.

SUCTION SCREEN i

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

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

The suction strainer should be installed as close to the pump suction as possible.

THE OPEN AREA OF THE STRAINER SHOULD HAVE A MINIMUM OF A 3 TO 1 RATIO TO THE AREA OF THE PUMP SUCTION.

The Ingersoll-Rand standard for suction strainers consists of a conical shaped steel plate. The plate has 1/16" perforations and is of sufficient size and thickness for the required flow.

Other type strainers may be used as long as they conform to the requirements stated above.

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

When the unit is being started, the gages on each side of the screen should be carefully watched. An increase in the differential pressure between the two gauges indicates that the screen is becoming clogged with dirt and scale. At this point, the pump should be shut down, and the screen cleaned and replaced. When the scale and dirt have been removed from the system as indicated by no further pressure from across ther screen, it may be removed. The screen should be used until all foreign material is removed from the system.

COUPLING ALIGNMENT CHECK

Refer to the section entitled "SHAFT/COUPLING ALIGNMENT" and perform a coupling alignment check as outlined. This check is recommended to insure the alignment has not been disturbed during the grouting of the bedplate or while installing suction and discharge piping.

:

TECHNICAL DATA

These pumps are furnished for a particular service condition. Changes in the hydraulic system may affect the pump's performance adversely. This is especially true if the changes reduce the pressure at the suction flange or if the liquid temperature is increased. In case of doubt, contact the nearest Ingersoll-Rand Office,

EFFECTS OF SPECIFIC GRAVITY

The capacity and total head in feet of liquid developed by a centrifugal pump are fixed for every point on the curve and are always the same for the same speed. Neither capacity nor total head will be affected by a change in the specific gravity of the liquid pumped. However, since the developed pressure is PSIG (pounds per square inch) and the brake horsepower to drive the pump are a function of the specific gravity of the liquid, both will be affected in direct proportion by any change in specific gravity. Therefore, a change in -specific gravity will affect the discharge gage pressure. Any changes should be noted, in that they may overload the purap'3 driver.

EFFECTS OF VISCOSITY

The pump is designed to deliver rated capacity at rated head for a liquid with a particular viscosity.

When contemplating operation at some viscosity other than for which the pump was originally designed, the changed conditions should be referred to Ingersoll-Rand Company for our recommendations,

CHANGING PUMP SPEED

Changing the speed of a centrifugal pump changes the capacity, total head and brake horsepower. The capacity will vary in a direct ratio with the speed, whereas the total head will vary as the ratio of the speed squared. The brake horsepower will vary as the ratio of the speed cubed .except in cases where the speed change also reduces the efficiency of the pump.

NET POSITIVE SUCTION HEAD (NPSH)

Any liquid, hot or cold, must be pushed into the impeller of the pump by some absolute pressure, such as the atmosphere or the vessel pressure from which the pimp takes its' suction,

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

There are two kinds of NPSH: the NPSH required by the pump, as shown on the pump curve, is the head needed to cover the losses in the pump suction; the second NPSH is that available in the system taking into account friction loss in auction piping, valves, fittings, etc. In all cases the NPSH Available, measured above vapor pressure, must exceed the NPSH Required in order to push the liquid into the pump,

OPERATING PRECAUTIONS

W A I N I N G

DO NOT WIPE DOWN IN THE VICINITY OF ROTATING PARTS, IF UNUSUAL NOISE OR VIBRATIO.NS OCCUR, SECURE THE PUMP AS SOON AS POSSIBLE.

W A R N I N G

THE UNIT MUST NOT BE OPERATED UNLESS COUPLING GUARD IS BOLTED IN PLACE. FAILURE TO OBSERVE THIS WARNING COULD RESULT IN INJURY TO OPERATING PERSON-NAL.

1. Never operate the pump with suction valve closed.

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

3. Never operate the pump unless a liquid source is availble.

PRE OPERATIONAL CHECKS

The following steps should be followed at initial start-up and after the equipment has been overhauled:

1. Ensure pump and piping is clean. Before putting the pump into opera-tion,- it should be thoroughly flushed out to remove the rust preventive as well as any foreign matter which may have accumulated during installation.

Take all possible care not to contaminate your system,

2. Clean and flush lubrication system. Fill reservoir with oil to the proper level. Ensure lube system is operable. (Refer to "LUBRICATION" section,)

3. Ensure pump rotor is properly aligned within casing (refer to "MAIN-TENANCE" section).

4. Turn pump rotor by hand or with strap wrench to make sure it turns freely.

5. Check Stuffing Box

A. If pump is equipped with a mechanical seal, ensure it is properly assem-bled and tightened (refer to "STUFFING BOX" section).

CAUTION

HOST CARTRIDGE SEALS ARE EQUIPPED WITH A SPACER BETWEEN THE GLAND PLATE AND DRIVE COLLAR. THIS SPACER MUST BE REMOVED BEFORE STARTING UNIT.

B. If pump is equipped with a packed box, insure box is properly packed (refer to "STUFFING BOX" section).

3 - 2

6. Ensure coupling is properly aligned and lubricated, and pump and driver is properly dowelled (refer to "SHAFT/COUPLING ALIGNMENT" procecure).

7. Ensure coupling guard is in place.

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

INITIAL START UP PROCEDURE

1. Close discharge valve if valve is not already closed.

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

3. Warm-Up Pump

Avoid severe thermal shocks to the pump as a result of sudden liquid temper-ature changes, The pump must be preheated prior to start-up. Unless otherwise specified the external temperature of the casing must be within 100 Degrees F. of the temperature of the liquid to be pumped at time of start-up. Due to the heavy metal sections, the casing will lag the liquid temperature during such changes, and severe temperature stresses and subse-quent misalignment of machined fits may result. Pre-heating is accomplished by circulating a small amount of hot, fluid through the casing by utilizing vents, drains or by pass from discharge. Preheat pump slowly at a rate not to exceed 100 Degrees F. per hour.

Prime pump and ensure pump suction valve is open.

C A U T I O N I

BEFORE STARTING OR WHILE OPERATING THE PUMP, THE CASING AND SUCTION LINE MUST BE COMLETELY FILLED WITH THE LIQUID BEING PUMPED. THE ROTATING PARTS DEPEND ON THIS 'LIQUID FOR LUBRICATION AND THE PUMP MAY SEIZE IF OPERATED WITHOUT LIQUID.

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

6. Check that pump is vented by observing leakage from casing vent and seal piping vent. Close vent when liquid is emitted,

7A. If pump is equipped with a mechanical seal, make sure seal piping is turned on.

7B. If pump is equipped with a packed box; turn on cooling water to lube oil cooler (when supplied), stuffing box jacket and smothering gland.

8. Start auxiliary oil pump.

• 3 - 3

9. Check pump rotation by starting unit momentarily. The direction of rotation is clockwise when facing pump shaft from coupling end. Note the pump coasts to a gradual stop.

IF PUMP STOPS ABRUPTLY WHEN DRIVER IS SHUT D O W N , I N V E S T I G A T E FOR PUMP BINDING. TAKE NECESSARY REMEDIAL ACTION BEFORE RESUMING OPERATION,

10A. Starting the driver (motor driven)

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

LUBRICATION

LUBRICATION SYSTEM

W A R N I N G

I

OPERATION OF THE UNIT WITHOUT PROPER LUBRICATION CAN RESULT IN OVERHEATING OF THE BEARINGS, BEARING FAILURES, PUMP SEIZURES AND ACTUAL BREAKUP OF THE EQUIPMENT EXPOSING OPERATING PERSONNEL TO PERSONAL INJURY. REFER TO LUBE OIL PIPING DRAWING.

Oil is supplied to the pressure lubrication system by one of the two (2) oil pumps. The main oil pump is mounted on a support head (6-172) which is bolted to the thrust end bearing body and cap (6-021/023).and is driven by the main pump shaft via a Lovejoy coupling (6-185).

A motor driven auxiliary oil pump is furnished to supply oil to the pressure lubrication system during starting and stopping periods. At time of start up, the auxiliary oil pump must be started manually. When the main oil pump supplies the required oil pressure, the auxiliary oil pump will automatical-ly stop by action of an auxiliary oil pump pressure switch mounted in the lubrication system. The auxiliary oil pump will remain in the standby state until such time as the lubricating oil pressure falls to a pre-determined value, at which time the auxiliary oil pump pressure switch will automat-ically start the auxiliarly oil pump.

During operation oil is taken from the oil reservoir by the oil pump and is directed to the oil cooler. From the oil cooler the oil is directed through the oil filter and is then supplied to the pump and driver bearings. A back pressure relief valve mounted in the lubrication system maintains the required system oil pressure of 15 PSI, The system is additionally equipped with a low pressure, pressure switch which trips the unit when the oil pressure in the lubrication system decreases to a pre-determined value or prevents the starting of the unit until adequate oil pressure is establish-ed. A gravity assisted, sloped oil return line conducts the oil from the pump and driver bearings back to- the system reservoir.

A check valve is mounted in the auxiliary oil pump discharge line to prevent oil from returning to the oil reservoir when the main oil pump is running and the auxiliary oil pump is shut down.

The oil reservoir has a capacity of 35 gallons.

The functions and control pressures of the pressure switches mounted in the lubrication system are as follows: (Refer to your Lube Piping Drawing,)

PRESSURE SWITCH NO. 8

Starts the auxiliary oil pump on falling oil pressure (10 PSI) and stops the auxiliary oil pump on rising pressure (20 PSI).

PRESSURE SWITCH NO. 7

Permits the start, of main pump driver at adequate oil pressure (11 PSI), Trips main punp driver on falling oil pressure (8 PSI),

MAKE PERIODIC INSPECTIONS

Remember that oil requires frequent replenishment at normal temperatures and very frequent, replenishment at high temperatures. Oil is always subject to gradual deterioration from use and contamination from dirt and moisture. In time, the accumulated sludge will be harmful to the bearings and cause premature wear. For this reason, draining and flushing with a safety solvent are necessary at six month intervals.

OIL SPECIFICATIONS

The ideal bearing lubricant is a straight, well refined, neutral mineral oil, preferably of the turbine type. It should not contain acid, chlorine, sulphur or more than a trace of free alkali. It is suggested that the oil conform to the following physical characteristics based on tests by ASTM Standard Methods.

OIL TEMPERATURE

Oil' temperature entering the plain/thrust end bearings should be maintained between 60 Degrees F. (16 Degrees C.) and 160 Degrees F. (71 Degrees C).

Alarm temperature is 170 Degrees F. (77 Degrees C.) with shut down tempera-ture set at 180 Degrees F. (82 Degrees C.).

If bearing oil temperature exceeds the above mentioned limits, cooling liquid to the lube oil cooler will have to be increased.

IMPORTANT

If necessary, to maintain the minimum bearing oil temperature at start up, oil in the lube oil reservoir may have to be heated or drained and replaced with warm oil.

•3-2

CLEANING THE LUBRICATION SYSTEM PRIOR TO OPERATION

Before operating the pump, the lubrication system should be thoroughly cleaned to remove any foreign matter that may have accumulated during shipment, storage or installation.

To clean the lubrication system proceed as follows:

1, Remove the bearing caps, bearing linings, thrust shoes and drain plugs, (Refer to "MAINTENANCE" section.)

2, Flush out the bearing bodies with kerosene.

3, Wash the bearing linings and thrust shoes with a suitable solvent.

Flush the entire lubrication system with flushing oil. Flushing oil should be compatible with lubricating oil that will be used.

5. During flushing operation examine the piping for leaks and correct as necessary. Also check for any obstructions that will interfere with free flow of oil to the bearings.

6. After flushing, replace drain plugs and piping. Reassemble bearings.

SECTION 5

STUFFING BOX

STUFFING BOX PACKING

Your pump is shipped without packing in the stuffing boxes. A complete set of packing is shipped in a separate box attached to the pump crate. Pre-serve the wrapper on the packing so that replacements can be ordered accordingly.

C A U T I O N

STUFFING BOXES THAT ARE PACKED TOO TIGHT OFTEN RESULT IN BURNED PACKING, SCORED SHAFT SLEEVES AND POSSIBLE ROTOR SEIZURE.

Eight (8) rings of 1/2 inch wide preformed packing (4-064) and a seal cage (when used) (4-014) must be installed in each stuffing box (refer to pump "Assembly Drawing" for proper sequence).

This packing is specifically designed to have an initial clearance between the I.D. of. the packing ring and 0.D, of the shaft sleeve. As the packing is gradually compressed by tightening the gland nuts, this clearance is decreased thus reducing the leakage, rate. In this fashion, the leakage can be precisely controlled without having the packing burn, cut off the leakage and damage the shaft sleeve.

Properly packed stuffing boxes are a must for efficient pump operation.

Note the directions with the packing and proceed as follows:

PACKING INSTALLATION

1. Install one ring of packing. Note that a clearance should exist between the shaft sleeve and the packing I.D., which insures a proper liquid flow for cooling and lubrication. Intimate contact between packing ring 0,D. and stuffing box I.D. should be obtained without forcing packing into the stuffing box. If too large, trim the butts slightly to obtain a good fit without overlapping. Press this ring of packing into stuffing box as far as it will go by installing gland halves (4-0165 and bearing down until gland contacts stuffing box. Remove gland halves.

NOTE

The successive packing ring joints must be staggered approximately 90 degrees from the proceeding ring.

2. If seal cage (4-014) is used, install and seat the next three (3) rings of packing (4-064), the seal cage (4-014) and the final four (4) rings of packing (4-064). Install gland halves to seat each ring, one at a time, and once again push them as far into the box as they will go. Remove gland halves,

NOTE

The packing cross-section may be slightly rectangular and, thus, may not allow insertion of all packing rings, No force should be exerted to compress the rings. After the exterior ring is in place, at least 1/8 inch clearance should exist between the face of the exterior ring and the face of the stuffing box,

3. Install the gland halves (4-016) and bolt together. Install the gland washers (4-246A) and nuts (4-279A). With the gland true to the shaft, hand tighten the gland nuts until the gland contacts the last ring of packing. Do not attempt to tighten gland nuts until suction pressure is applied to the pump, Following application of suction pressure to pump, allow liquid to flow freely from stuffing box for a short period of time. This will provide time for the packing to absorb liquid which will provide lubrication during start up and protection against burn out.

4. Operate the unit for a minimum of one half hour, allowing the gland to leak freely. This is necessary to "break-in" the packing and prevent over-heating. After "break-in" gradually reduce gland leakage with the pump in operation. Leakage will decrease when pump, is rotating.

5. If the last ring of packing was left out in Step 2 above, secure pump and install the additional ring at this time, or when convenient. Do not force packing rings into stuffing box at any time.

5- 2 55

6. Continue operation of the pump gradually reducing the leakage. If the flow decreases too rapidly during the procedure, slack off gland nuts to increase flow. If leakage is stopped, secure pump for a short period, to allow gland to cool. Slack off gland nuts approximately 1/2 turn and restart. Repeat as necessary, until minimum required leakage is re-established.

C A U T I O N

WHEN MAKING GLAND ADJUSTMENTS, NEVER TURN GLAND NUTS MORE THAN ONE OR TWO FLATS, SUFFICIENT TIME SHOULD BE ALLOWED BETWEEN EACH ADJUSTMENT SO THAT COMPRESSION OF THE PACKING BY THE GLAND CAN BE REFLECTED THROUGH ALL OF THE PACKING RINGS.

7. If leakage is cut off completely and smoke issues from stuffing box, secure the pump, remove packing and repack with a new set,

8. Packing must be replaced when gland adjustment can no longer control

leakage.

C A U T I O N

PACKING MUST ALWAYS BE REPLACED AS A COMPLETE SET.

STUFFING BOX PACKING REMOVAL

1. Remove gland nuts (4-279A), washers (4-246A) and packing gland (4-016).

2. Remove old packing (4-064) and seal cage (4-014) with a packing hook.

3. Saturate a- strong absorbent piece of cloth with solvent. Using a piece of wood push cloth down and around inside of stuffing box until it is clean.

4. Check shaft sleeve (4-008) for wear. A small mirror and a flashlight can be used to check the condition of the length of the shaft sleeve.

If scoring is .010 inch to ,020 inch deep, the shaft sleeve must be replac-ed.

HEATING IMPELLERS FOR REMOVAL

A, Apply heat (torch with fine tip) to periphery (outer 1.5 inches) of impeller until temperature reaches 375 Degrees F. (minimum) to 400 Degrees F, (maximum). Use tempilstick to determine temperature..

B. Maintaining temperature between 375 - 400 Degrees F. at the periphery, apply heat down through the vane passages, thus heating the hub.

C. Do not apply heat directly to the shaft as this will cause the shaft to expand,

D. With periphery, shroud and hub at temperature, remove impeller,

E. If the impeller does not move freely off the shaft, additional heatmay be necessary. THIS HEATING SHOULD' BE STARTED AT THE PERIPHERY OF THE IMPELLER NOT THE HUB. (Additional heating of the hub area at this time will tighten the impeller on the shaft, not loosen it.) If the impeller still fails to come free, the impeller and shaft should be allowed to cool' com-pletely and the heating process repeated starting at Step A on preceeding page.

INSPECTION AND RENEWAL OF PARTS

1, Having completely dismantled the rotor, check the shaft for runout using nV" blocks or rollers placed under the normal bearing areas. Runout not to exceed .002" TIR. "

2. Wire brush the pump parts thoroughly. Clean off all scale, carbon, etc, Examine parts for wearing, corrosion and erosion.

3. Check shaft sleeve, throttling sleeve and center sleeve for wear. Replace if required.

4. The casing rings/impeller rings are renewable and should be replaced when badly grooved, and/or when pump performance does not meet the system requirements. Whenever it becomes necessary to replace either wearing ring, both rings involved (casing ring and impeller ring) must be ordered and replaced as they are furnished standard size only (impeller rings approxim-ately ,08 inches oversize). Be sure to re-establish the original running clearance between the two wearing rings involved.

A, If new casing rings are used, make sure that they seat in both the upper and lowr half casing and that the anti-rotation device is properly located in its respective lower half casing fit. The use of a scraper on the ring to casing fit will help to fit the ring to the casing,

B. Impeller ring removal and installation.

Remove impeller rings by removing the set screws (1-259) and machining off; or, grind two slots diametrically opposite across the face of the ring so it can be split apart. Exercise caution if. rings are removed by grinding so as not to damage impeller hubs. See sketch below.
