Mechanical-seal maintenance
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified. Prior to startup,
make sure that all areas that could leak pumped fluid to the work environment are closed.
The mechanical seal used in an ATEX classified environment must be properly certified.
The mechanical seal must have an appropriate seal flush system. Failure to do so will result in
excess heat generation and seal failure.
CAUTION:
Never operate the pump without liquid supplied to mechanical seal. If you run a mechanical seal dry,
even for a few seconds, this can cause seal damage. Physical injury can occur if a mechanical seal fails.
NOTICE:
•
Sealing systems that are not self-purging or self-venting, such as plan 23, require
manual venting prior to operation. Failure to do so will result in excess heat generation and
seal failure.
• Cooling systems, such as those for bearing lubrication and mechanical-seal systems, must
be operating properly to prevent excess heat generation, sparks, and premature failure.
•
The mechanical seal must have an appropriate seal flush system or excess heat
generation and seal failure can occur.
Cartridge-type mechanical seals
Cartridge-type mechanical seals are commonly used. Cartridge seals are preset by the seal
manufacturer 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.
