4.5 Piping checklists
4.5.1 Fastening
WARNING:
Risk of serious personal injury or property damage. Fasteners such as bolts and nuts are criti-
cal to the safe and reliable operation of the product. Ensure appropriate use of fasteners during
installation or reassembly of the unit.
•
Use fasteners of the proper size and material only.
•
Replace all corroded fasteners.
•
Ensure that all fasteners are properly tightened and that there are no missing fasteners.
4.5.2 General piping checklist
Precautions
WARNING:
•
Risk of premature failure. Casing deformation can result in misalignment and contact with
rotating parts, causing excess heat generation and sparks. Flange loads from the piping
system, including those from the thermal expansion of the piping, must not exceed the
limits of the pump.
•

critical to the safe and reliable operation of the product. Ensure appropriate use of fasten-
ers during installation or reassembly of the unit.
•

•

•
Ensure that all fasteners are properly tightened and that there are no missing fas-
teners.
CAUTION:
Do not move the pump to the pipe. This could make final alignment impossible.
CAUTION:
Never draw piping into place at the flanged connections of the pump. This can impose danger-
ous strains on the unit and cause misalignment between the pump and driver. Pipe strain ad-
versely affects the operation of the pump, which results in physical injury and damage to the
equipment.
Flange loads from the piping system, including those from the thermal expansion of
the piping, must not exceed the limits of the pump. Casing deformation can result in contact
with rotating parts, which can result in excess heat generation, sparks, and premature failure.
