6.2.4 Regrease the grease-lubricated bearings
NOTICE:
Risk of equipment damage. Ensure that the grease container, the greasing device, and the fit-
tings are clean. Failure to do so can result in impurities entering the bearing housing while re-
greasing the bearings.
1.
Wipe dirt from the grease fittings.
2.
Insert the amount of grease as noted in the Grease Lubrication Schedule above through the grease
fitting. If grease comes out the lip seal or the heat flinger, make sure that the cavity is not completely
filled with grease.
3.
Wipe off any excess grease.
4.
Recheck the alignment.
The bearing temperature usually rises after you regrease due to an excess supply of grease. Tempera-
tures return to normal in about two to four operating hours as the pump runs and purges the excess
grease from the bearings.
6.2.5 Lubricate the bearings after a shutdown period
1.
Flush out the bearings and bearing frame with a light oil to remove contaminants.
During flushing, make sure to rotate the shaft slowly by hand.
2.
Flush the bearing housing with the proper lubricating oil to ensure oil quality after cleaning.
3.
Refer to
Reassembly
section for proper bearing procedure.

6.3.1 Mechanical-seal maintenance
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified.
CAUTION:
Running a mechanical seal dry, even for a few seconds, can cause seal failure and physical
injury. Never operate the pump without liquid supplied to the mechanical seal.
Cartridge-type mechanical seals
Cartridge-type mechanical seals are commonly used. Cartridge seals are preset by the seal manufactur-
er and require no field settings. 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.
