Goulds Pumps 3996 Installation, Operation And Maintenance Instructions page 8

Alignment:
Shaft alignment procedures must be followed to prevent catastrophic failure of drive
WARNING
components or unintended contact of rotating parts. Follow coupling manufacturer's
coupling installation and operation procedures.
Before beginning any alignment procedure, make sure driver power is locked out. Failure
WARNING
to lock out driver power will result in serious physical injury.
Piping:
Never draw piping into place by forcing at the flanged connections of the pump. This may
CAUTION
impose dangerous strains on the unit and cause misalignment between pump and driver.
Pipe strain will adversely effect the operation of the pump resulting in physical injury and
damage to the equipment.
Flanged Connections:
WARNING
Use only fasteners of the proper size and material.
WARNING Replace all corroded fasteners.
WARNING Ensure all fasteners are properly tightened and there are no missing fasteners.
Startup and Operation:
WARNING
When installing in a potentially explosive environment, please ensure that the motor is
properly certified.
Operating pump in reverse rotation may result in contact of metal parts, heat generation,
WARNING
and breach of containment.
WARNING Lock out driver power to prevent accidental start-up and physical injury.
The impeller clearance setting procedure must be followed. Improperly setting the
WARNING clearance or not following any of the proper procedures can result in sparks, unexpected
heat generation and equipment damage.
If using a cartridge mechanical seal, the centering clips must be installed and set screws
loosened prior to setting impeller clearance. Failure to do so could result in sparks, heat
WARNING
generation, and mechanical seal damage.
The coupling used in an ATEX classified environment must be properly certified and
WARNING
must be constructed from a non-sparking material.
Never operate a pump without coupling guard properly installed. Personal injury will
WARNING
occur if pump is run without coupling guard.
Make sure to properly lubricate the bearings. Failure to do so may result in excess heat
WARNING
generation, sparks, and / or premature failure.
The mechanical seal used in an ATEX classified environment must be properly certified.
Prior to start up, ensure all points of potential leakage of process fluid to the work
CAUTION
environment are closed.
