Receiving:
Assembled pumping units and their components are heavy. Failure to properly lift
and support equipment can result in serious physical injury and/or equipment
damage. Lift equipment only at specifically identified lifting points or as
instructed in the current IOM. Current manuals are available at
www.gouldspumps.com/literature_ioms.html or from your local ITT Goulds
Pumps sales representative. Note: Lifting devices (eyebolts, slings, spreaders, etc.)
must be rated, selected, and used for the entire load being lifted.

Shaft alignment procedures must be followed to prevent catastrophic failure of
drive components or unintended contact of rotating parts. Follow coupling
manufacturer’s coupling installation and operation procedures.
