The bearing temperature usually increases by 5°C to 10°C | 9°F to 18°F after you regrease due to an
excess supply of grease. Temperatures return to normal in about two to four operating hours as the
pump runs and purges the excess grease from the bearings.
6.3 Shaft seal maintenance
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 physi-
cal 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 manu-
facturer and require no field settings. Cartridge seals installed by the user require disengagement of
the holding 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
installation and setting.
Reference drawing
The manufacturer supplies a reference drawing with the data package. Keep this drawing for future
use when you perform maintenance and seal adjustments. The seal drawing specifies the required
flush fluid and attachment points.
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. Due to the diversity of
operating conditions, it is not possible to give definite indications as to the life of a mechanical seal.
6.3.2 Packed stuffing-box maintenance
WARNING:
• Packed stuffing boxes are not allowed in an ATEX-classified environment.
• Failure to disconnect and lock out driver power may result in serious physical injury.
Never attempt to replace the packing until the driver is properly locked out.
Accepted leakage rate
It is not necessary to shut down or disassemble the pump to inspect the packing operation. During
normal operation the packing should leak approximately 30-100 drops per minute.
