Installation Precautions
1. Do not begin installation until all parts are accounted for and all instructions are clearly understood.
2. Units mounted on bedplates must always be lifted by the lifting lugs or holes provided in the bedplates, or by slings passed under the bottom of the bedplate.
3. Spreader bars and/or blocks must be used, as required, on slings to prevent damage to the unit, or to all pipes and accessories on the unit.
4. Units received with the components mounted on a common bedplate were accurately aligned at the factory before shipment. These units are always shipped with the coupling disconnected. All bedplates are flexible to some extent and therefore, must not be relied upon to maintain the factory alignment. Realignment is necessary after grouting.
5. The clearances required for disassembly of the unit are shown on the Unit Outline drawing.
6. Check the site piping for fit, clean it (see FLUSHING below), test it for leaks and install it.
7. Retain temporary connection and pipe flange covers until the unit is leveled, aligned and ready for operation.
8. Do not bolt up connecting main pipe flanges until the grout has set for 48 hours, or follow manufactures recommendations, and the lines are cleaned.
9. Final alignment check should be made under actual operating conditions.
Installation Procedures
1. Establish centerline bench marks on building column.
2. Install all auxiliary equipment located below bedplate or soleplate.
3. Make sure top of foundation is rough to insure good grout bond.
4. Locate chocks or jacks on the foundation at locations shown on the Outline Drawing and seat them in grout paste on concrete foundations.
5. Place equipment into position on the foundation leveling devices. Adjust chocks or jacks to obtain contact at all bedplate and soleplate locations as designated by the Outline Drawing. Allow approximately 2 inches grout clearance above the foundation.
6. Check all unit components on the bedplate or soleplates to the alignment setting shown on the Outline Drawings and cold shaft alignment.
BOLTS, SHIMS, DOWELS AND OTHER SPECIAL HARDWARE ARE USED TO KEEP THE ELEMENTS IN POSITION DURING SHIPPING AND HANDLING. THESE HARDWARE ITEMS MUST BE REMOVED PRIOR TO FINAL ALIGNMENT OF THE EQUIPMENT. REFER TO THE MAJOR ASSEMBLY DRAWINGS, NOTES AND SPECIAL TAGS FOR LOCATIONS.
DRIVING AND/OR DRIVEN EQUIPMENT, OR OTHER COMPONENTS, SHIPPED DIRECTLY TO THE SITE BY MANUFACTURERS OTHER THAN SIEMENS DEMAG DELAVAL TURBOMACHINERY, INC. REQUIRE DRILLING, TAPPING AND DOWELING AT THE SITE UNLESS, BY A CONDITION OF THE SALE THE MANUFACTURER OF THE UNMOUNTED EQUIPMENT HAS FURNISHED A DRILLING TEMPLATE TO SIEMENS DEMAG DELAVAL TURBOMACHINERY, INC. PRIOR TO THE SHIPMENT OF THE BEDPLATES OR SOLEPLATES.
7. Level and align. See “Alignment” below.
8. Grout. See “Grouting”below.
9. Do not connect the coupling halves until the rotation of the connecting unit(s) has been verified by an operating check, and tested for satisfactory trip and control operation.
Alignment
1. Refer to the attached “Shaft Alignment Procedure”, Document F.S.M. 6.300 and to the foregoing paragraphs on Installation Precautions and Installation Procedures.
2. Depending upon whether or not the unit has transverse leveling lugs use either of the following procedures:
a) WITH TRANSVERSE LEVELING LUGS
To assist in preliminary alignment, transverse leveling lugs are factory placed near the middle and each end of the bedplate. Place a straight edge with precision spirit level across these lugs and adjust the supports until the bedplate is level.
b) WITHOUT TRANSVERSE LEVELING LUGS To assist in preliminary alignment, the bedplates mounting pad surfaces are used for alignment. By placing a straight edge with a spirit level across these machined surfaces or with an optic measurement (these surfaces can be used as mark targets) adjust leveling devices underneath the bedplate until level.
COMPRESSOR ROTATION MUST BE CHECKED BEFORE TURNING THE SHAFT. TURNING THE SHAFT COUNTER TO ROTATION WITH SEALS INSTALLED WILL DAMAGE THE SEALS.
TO AVOID BEARING DAMAGE BE SURE BEARINGS ARE WELL LUBRICATED BEFORE ATTEMPTING TO TURN SHAFT.
IN CHECKING ALIGNMENT AT THE COUPLING FACES, EACH COUPLING FACE SHOULD BE CHECKED WITH RESPECT TO THE OTHER WHEN THE SHAFTS ARE TURNED TOGETHER THROUGH 360 DEGREES AND WHEN MEASURED AT LEAST AT FOUR POINTS.
INDICATED MISALIGNMENT: SHOULD NOT EXCEED PARALLEL 0.002 IN. (0.05MM) AND OFFSET 0.002 IN. (0.05MM) OF DESIRED SETTING
USE MICROMETERS OR FEELERS BETWEEN THE COUPLING FACES TO CHECK ANGULAR MISALIGNMENT AND DIAL INDICATORS STRAPPED TO THE SHAFT OF ONE MACHINE SHOULD BE USED TO INDICATE PARALLEL MISALIGNMENT OF THE CONNECTING SHAFT.
THE SETTING ESTABLISHED AT THE FACTORY IS BASED UPON ESTIMATED OPERATING TEMPERATURE.
THE ACTUAL INSTALLATION OF INSULATION AND LAGGING MAY RESULT IN DIFFERENT AMOUNTS OF EXPANSION THAN THOSE ESTIMATED. THE ACTUAL ALIGNMENT SHOULD BE CHECKED AFTER THE UNITS HAVE BEEN OPERATED AT THE NORMAL OPERATING TEMPERATURES SUFFICIENTLY LONG ENOUGH THAT THE TEMPERATURES ARE CONSTANT.
3. When the bedplate is aligned and grouted, adjust the component supports to align the coupling(s).
4. Tighten the equipment hold down bolts and check the coupling alignment. Readjust leveling devices underneath the bedplate if necessary.
5. Final alignment and necessary adjustments will be determined from an alignment check under actual operating conditions.
6. Dowel all equipment to hold the final aligned position.

1.0 SCOPE
Directions for the disassembly, inspection of parts and reassembly of the rotating element including the opening and closing of the volute case.
2.0 PREPARATION
Prior to and during work verify that the atmosphere is not potentially explosive. Stop all work immediately if any danger arises.
Study the Pump Cross-Section drawing and be familiar with the design details and assembly sequence.
Phase the operations and have equipment available for impeller/shaft sleeve mounting and dismounting, and also measuring devices, heating facilities and a torque wrench for case bolting.
Be familiar with the heating temperatures, mounting and dismounting forces and torque values.
3.0 EXAMINATION AND CLEANLINESS
Unless the volute case needs renovation, the bottom half will remain installed after the top half has been dismantled and the rotating element removed.
The case halves must be protected from the ingress of dirt and physical damage during the maintenance cycle. The rotating element must be removed to a clean work area for disassembly.
Some preliminary examination and assessment of the extent of the work can be made when the volute case top half is lifted. More detailed inspection of part size and condition must be made after element disassembly.
4.0 CASE TOP HALF REMOVAL
It is assumed that all items of maintenance described in the MAINTENANCE Section of this manual have been completed.
4.1 Disconnect and remove sections of piping that will interfere with the top half removal. Cap piping ends to prevent the entry of dirt.
4.2 Install spacers between the mechanical seal sleeve drive collars and the gland plates, then loosen drive collar screws.
• Loosen and back-off mechanical seal gland nuts at each end. Free gland plates from case gland faces but leave mechanical seals in place.
• Check total axial movement of the element in the case (Endo) and record for use at re-assembly.
• Remove case taper pins and cap nuts from split line studs.
• Rig chains to the two case lifting points; use the four jackscrews to break the joint and lift the top half casing vertically to clear the rotating element.
• The split line face of both halves of the case and the case studs, which are now exposed, must be protected from corrosion or physical damage.
5.0 ELEMENT REMOVAL AND DISASSEMBLY
Without further disassembly, a fairly extensive visual examination of the pump parts can be made. At this point, it will be determined whether element removal is necessary.
Proceed as follows to remove rotating element:
5.1 Remove bearing assemblies as described in the BEARING ASSEMBLY Section of this manual.
5.2 Remove nuts from studs and slide the mechanical seals from shaft. Clean and store mechanical seals in accordance with manufacturers instructions ready for re-use.
5.3 Rig rope slings around the shaft and lift the rotating element without using excessive force. If the case rings and bushings bind in the case grooves, careful use of a pry bar at each location will help free them.
5.4 If the element is to be transported, it should rest in a cradle with solid supports at each end and at the center.
5.5 In a clean work area, disassembly can proceed by removing the throat bushings 456.218, the throttle bushing 542.215, the center bushing 546.210 and the case rings 502.203 and 502.206 from both ends of the element.
5.6 Further disassembly requires the removal of impellers and sleeves that were shrunk on to the shaft.
It must be emphasized that successful results using the following process requires experience or first hand advise from a Sulzer representative. The components must be heated and permanent damage can result if the level and duration of heating is not properly controlled.
5.7 The impeller bores and corresponding shaft fits are different diameters at each location.
Before dismantling, clearly diagram the element making note of the number marked on each impeller and its position on the shaft.
5.8 Clamp one end of the shaft in a vice using soft jaws. Clamp at the shaft section that carries the mechanical seal not on the bearing journals.
The free end of the shaft must rest in a steady rest with 3 or 4 impellers outboard of the steady rest ready for removal.
5.9 The throttle sleeve 522.233 and each impeller 230.241 through 230.254 is secured axially with a split ring 501.265 encapsulated in the bore of the secured part.
During the heating and removal process, the throttle sleeve and each impeller must be pushed back to remove the split ring then withdrawn from the shaft.
5.10 Clean off any deposit ahead or behind the part to be removed using a non-abrasive metal cleaner.
5.11 For heating, use a gas torch fitted with a 1" - 2" heating rosebud. Do not use a cutting torch.
5.12 Before starting, make sure 2 people are available, each person understanding their assigned tasks for the removal process and properly equipped.
5.13 Heat part evenly, all around and from the outside to the inside, spending proportionally more time on the impeller hub. 2 minutes of elapsed time is normally sufficient.
5.14 The person not holding the torch must free the part, grasping with gloved hands to pull back, remove the split ring and withdraw part from the shaft.
Note: Tapping with a mallet may facilitate removal but take care not to damage the impeller shrouds in the process.
Take care not to allow too much heat to soak into the shaft. If significantly more than 2 minutes elapsed during the heating cycle, stop heating, allow to cool completely and start again.
If problems persist, contact a Sulzer representative.
5.15 As the sleeve or impeller is removed, the drive key can be lifted from its keyseat and the shaft allowed to cool.
Note: At this time check for a snap ring at the back of the impeller seating surface and remove. A snap ring is added as an option to secure impeller against reverse axial movement.
5.16 A stationary ring 502.206 and an interstage bushing 541.209 can be removed with the removal of each impeller.
5.17 To remove the impeller wear rings 503.222, 503.225 and 503.226, first remove the 3 to 8 radial screws securing the rings to the impeller.
5.18 With the radial screws removed, a ring puller can be applied to the edge of the wear ring adjacent to the impeller shroud to remove the ring.
6.0 VOLUTE CASE INSPECTION
Before installation of the element into the volute case, the volute case must be inspected for flatness on the case parting flange, both top and bottom halves, and the bore must be checked for size.
6.1 Case Parting Flange Flatness
Obtain a precision straightedge that will cover the length and width of the pump case parting flange. Obtain a set of feeler gauges.
First, choose one end of either the top or bottom case half and lay the straightedge across the width (parallel to the suction/discharge nozzles) at either end right over the stuffing box bore.
Attempt to slide a .002 inch feeler gauge underneath the straightedge measuring at every point that it covers the case. .002 inches or less is the maximum gap allowed. If .003" feeler gauge or above will slide underneath the straightedge, the case must be rejected for non-flatness. Contact a Sulzer representative for instructions. If the readings are acceptable, move the straightedge down the case half, positioning it over every running fit in the bore and repeat the above procedure. Likewise, repeat the procedure for the other case half.
Note: On the bottom half, position the straightedge so that studs do not have to be removed.
6.2 Bore Check for Size
Note: Using stationary wear parts as templates.
From the spare parts, obtain one of each of the following: Series Stationary Ring, First Stage Stationary Ring, Throttle Bushing, and the Center Bushing.
6.2.1 Using the series stationary ring, first position it in all the series ring and interstage bushing fits. The ring should go all the way down in the fit and over the anti-rotation pin without binding. Rotate the ring back and forth to make sure the ring is engaging the anti-rotation pin. This should be a close registration fit just loose enough for freedom of movement - not tight. If the ring locates on the fit but is tight, the case fit can be hand scraped using tool steel to achieve this freedom of movement. If the ring will not even sit down on the fit, the case must be removed for re-machining. If the ring locates on the fit and is loose such that it can be rocked back and forth, the pump case must be removed for re-machining.
Repeat this procedure using the other pieces in their corresponding fits. Use the same acceptance criteria as above.
Note: While measuring, do not overlook the area within 1" (25 mm) of the edge of the bore. If the pump has been through a seizure, this area is most likely to be distorted, and is the most critical area for sealing the split line.
6.2.2 Upon acceptance of 6.2.1, lay the straightedge along the length (perpendicular to suction/discharge nozzles) of the volute case half starting just even with the knife edge of the bore. Measure for flatness using the procedure and acceptance criteria of 6.1 above. Next, move the straightedge out away from the bore in 2 or more equal spaces. Measure for flatness on every move of the straightedge. When complete, move the straightedge to the other side of the bore and measure for flatness following the same procedure as before. Repeat the same procedure for both case halves.
7.0 INSPECTION OF OTHER PARTS
7.1 Clean and Inspect After disassembly, clean the parts and inspect for wear or damage, in particular the running surfaces of all rings, sleeves and bushings.
Damaged or excessively worn parts should be discarded. Reusable parts should be prepared for short term storage by applying light machine oil to all machined surfaces.
7.2 Mechanical Seal - As the mechanical seals are removed, they should be immediately cleaned and stored in accordance with the manufacturers instructions.
