Follow industry-standard procedures, such as API RP 686/ PIP REIE 686, or this proce- dure before you grout the baseplate.
4.2 Baseplate-mounting procedures 4.2.2 Prepare the foundation for mounting Chip the top of the foundation to a minimum of 25.0 mm | 1.0 in. in order to remove porous or low- strength concrete. If you use a pneumatic hammer, make sure that it does not contaminate the surface with oil or other moisture.

Cartridge seals installed by the user require disengagement of the hold- ing clips prior to operation, allowing the seal to slide into place. If the seal has been installed in the pump by ITT, these clips have already been disengaged. Other mechanical seal types For other types of mechanical seals, refer to the instructions provided by the seal manufacturer for instal- lation and setting.
5.8 Pump priming Seal flushing methods Table 1: You can use these methods in order to flush or cool the seal: Method Description Product flush Run the piping so that the pump pushes the pumped fluid from the casing and injects it into the seal gland. If necessary, an external heat exchanger cools the pumped fluid before it enters the seal gland.
5.9 Start the pump Item Description Discharge isolation valve Check valve Suction isolation valve Figure 36: Suction supply above pump 5.9 Start the pump WARNING: Risk of equipment damage, seal failure and breach of containment. Ensure all flush and cool- ing systems are operating correctly prior to starting pump.
5.10 i-ALERT®2 Equipment Health Monitor Restart the driver. Monitor the pump while it is operating: Check the pump for bearing temperature, excessive vibration, and noise. If the pump exceeds normal levels, then shut down the pump immediately and correct the prob- lem.
5.12 Shut down the pump • Establish baseline vibration readings in order to determine normal running conditions. If the unit is running roughly, then consult the factory. • Monitor all gauges to ensure that the pump is running at or near rating and that the suc- tion screen (when used) is not clogged.
5.14 Make the final alignment of the pump and driver NOTICE: Always reset the health monitor when the pump is started after maintenance, system change, or being shut down for an extended period of time. Failure to do so may result in false baseline levels that could cause the condition monitor to alert in error.
5.15 Doweling the pump casing If the temperature differential is high the baseplate is supplied with provision to accommodate differential temperature doweling. This design ensures the alignment between the pump and driver is maintained while allowing the case to thermally move. When the driver is mounted at the factory, the driver is not doweled in order to allow for final field align- ment.

6 Maintenance 6 Maintenance 6.1 Maintenance schedule Maintenance inspections A maintenance schedule includes these types of inspections: • Routine maintenance • Routine inspections • Three-month inspections • Annual inspections Shorten the inspection intervals appropriately if the pumped fluid is abrasive or corrosive or if the envi- ronment is classified as potentially explosive.
Cartridge seals installed by the user require disengagement of the hold- ing clips prior to operation, allowing the seal to slide into place. If the seal has been installed in the pump by ITT, these clips have already been disengaged. Other mechanical seal types For other types of mechanical seals, refer to the instructions provided by the seal manufacturer for instal- lation and setting.
6.4 Disassembly Before you start the pump Check the seal and all flush piping. Mechanical seal life The life of a mechanical seal depends on the cleanliness of the pumped fluid.

6.6 Reassembly 361F 361H Figure 71: Diaphragm sleeve reassembly Install the snap ring (361F) into the groove. Assemble the first-stage impeller (101) as in Step 1. On double-suction pumps only install the locating ring (361H), then slide on the first-stage impeller and install the snap ring (361F).
6.6 Reassembly Slide the sleeve onto the shaft past the locating ring groove, put the locating ring (361H) in place, and slide the sleeve back until snug. Install the snap ring (361F) into the groove. CAUTION: The impeller and wear-ring clearance setting procedures must be followed. Improperly set- ting the clearance or not following any of the proper procedures can result in sparks, unexpect- ed heat generation, and equipment damage.
6.6 Reassembly Figure 75: Installing the rotor Position the sling so that both loops around the shaft fall approximately at the seal diameter and in front of the seal chambers (220, 221). Lower the rotating assembly, making sure all stationary parts fit into the groove locks. While maintaining tension on the rotating assembly, slide the lower half of all stage rings (144), the center bushing (155), and the diaphragm (146), if applicable, into the lower half of the casing.

Check and confirm that the separation between the seal chamber center and the rotor center is 0.127 mm | 0.005 in. or less. If the separation is greater than 0.127 mm | 0.005 in., then contact your ITT representative for assis- tance.
6.6 Reassembly For standard clearance use a 0.076 mm | 0.003 in. feeler gauge. For API clearance use a 0.152 mm | 0.006 in. feeler gauge. Make minor adjustments to the bearing housings accordingly. Recheck the shaft-to-seal chamber bore TIR after this adjustment. Side-to-side readings must be 0.127 mm | 0.005 in.

6.6 Reassembly While the bearings are hot, tighten the locknut by hand with a spanner wrench until the bearing is snug against the shaft shoulder. Allow the bearing assembly to cool slowly to room temperature. Do not rapidly cool the bearings with compressed air or other means. When the bearing assembly is fully cooled, remove the locknut, install the lockwasher (382), and install the locknut.
6.6 Reassembly Fit the labyrinth seal (332C) into the bore of the cover (109A). NOTICE: Make sure that the expulsion port is at the 6 o'clock position and is properly seated. Install the bearing end cover (109A) and the bearing end-cover gasket (360A) with the end-cover capscrews (371C).

6.6 Reassembly NOTICE: Make sure that the expulsion port is at the 6 o'clock position and is properly seated. Assemble the inboard end cover (160) and the inboard bearing end-cover gasket (360A) onto the shaft. Assemble the radial bearing (168) onto the shaft (122). The bearings are interference fit.
6.6 Reassembly Install the oil ring (114). Install the end-cover gasket on the outboard side (360A). Assemble the outboard labyrinth seal (332A) into the outboard radial-end cover (160): Clean the end cover with a solvent. Fit the labyrinth seal (332A) into the bore of the cover (160). Tap the seal in with a hammer.

6.6 Reassembly 21. If pump has been supplied with axial proximity probes, screw the axial proximity probes into the filler plate (441A). Do not tighten the axial proximity probes all the way down until they come into contact with the thrust collar. The axial proximity probes should be set at .050” away from the thrust collar. NOTICE: If the axial proximity probes are touching the thrust collar during operation, the axial proximity probes will break and fill the bearing housing with debris resulting in premature bearing failure.
6.6 Reassembly NOTICE: Make sure the expulsion port is at the 6 o’clock position and is properly seated. Lift the lower half of the bearing housing (134) into place. Install the case-to-bearing housing studs (371T). Place the installed inboard labyrinth seal (333A) in the lower housing. Finger tighten the lower housing to the case-to bearing housing flange with the case-to-bearing housings studs (371T) and nuts (427J).
