General Precautions
WARNING
Before beginning any alignment procedure, make sure driver power is locked out.
Failure to lock out driver power will result in serious physical injury.
CAUTION
Piping:
Never draw piping into place by forcing at the flanged connections of the pump.
This may 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.
WARNING
Flanged Connections:
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.
WARNING
Startup and Operation:
When installing in a potentially explosive environment, please ensure that the
motor is properly certified.
WARNING
Operating pump in reverse rotation may result in contact of metal parts, heat
generation, and breach of containment.
WARNING
Lock out driver power to prevent accidental start-up and physical injury.
WARNING
The impeller clearance setting procedure must be followed. Improperly setting
the clearance or not following any of the proper procedures can result in sparks,
unexpected heat generation and equipment damage.
WARNING
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 generation, and mechanical seal damage.
WARNING
The coupling used in an ATEX classified environment must be properly certified
and must be constructed from a non-sparking material.
WARNING
Never operate a pump without coupling guard properly installed. Personal injury
will occur if pump is run without coupling guard.
WARNING
Make sure to properly lubricate the bearings. Failure to do so may result in excess
heat generation, sparks, and / or premature failure.
CAUTION
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 environment are closed.
CAUTION
Never operate the pump without liquid supplied to mechanical seal. Running a
mechanical seal dry, even for a few seconds, can cause seal damage and must be
avoided. Physical injury can occur if mechanical seal fails.
WARNING
Never attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.
WARNING
Dynamic seals are not allowed in an ATEX classified environment.
WARNING
DO NOT operate pump below minimum rated flows or with suction and/or
discharge valve closed. These conditions may create an explosive hazard due to
vaporization of pumpage and can quickly lead to pump failure and physical injury.
