6.3 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.
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.
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. In clean water applications, typical mechanical seal life spans two to
three years.
6.4 Flood-damaged pump maintenance
WARNING:
• Always disconnect and lock out power before servicing to prevent unexpected startup.
Failure to do so could result in death or serious injury.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
Perform these maintenance tasks if your pump has been flood damaged:
• Replace bearings and grease if the pump has been subjected to flood conditions.
• Make sure that the motor is evaluated by a qualified motor shop before you place it
back into service.
