General Precautions
NOTE Before beginning any alignment procedure, make sure driver power is locked out.
Failure to lock out driver power will result in serious physical injury.
NOTE
Piping: Never pull 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 affect the operation of the
pump resulting in physical injury and damage to the equipment.
NOTEFlanged Connections: Use only fasteners of the proper size and material.
NOTEReplace all corroded fasteners.
NOTEEnsure all fasteners are properly tightened and there are no missing fasteners.
NOTE
Startup and Operation: When installing in a potentially explosive environment,
please ensure that the motor is certified explosion proof.
NOTEDo not operate pumps in reverse rotation may result in contact of metal parts, heat
generation, and breach of containment.
NOTELOCK out Tag out drivers
NOTEThe 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.
NOTEIf 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.
NOTEThe coupling used in an ATEX classified environment must be properly certified
and must be constructed from a non-sparking material.
NOTENever operate a pump without coupling guard properly installed. Personal injury
will occur if pump is run without coupling guard.
NOTEProperly lubricate the bearings. Failure to do so may result in excess heat
generation, sparks, and / or premature failure.
NOTEThe mechanical seal used in an ATEX classified environment must be properly
certified. Prior to start up; ensure points of potential leakage of process fluid to the
work environment are closed.
NOTEDo not 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.
NOTENever attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.
NOTEDynamic seals are not allowed in an ATEX classified environment.
NOTEDO NOT operate pump below minimum rated flows or with suction and/or
discharge valve closed. These conditions can create an explosive and hazardous to
vaporization of pumped fluid and can quickly lead to pump failure and physical
injury.
