maintenance personnel must realize this and follow safety measures. Personal injuries will result if procedures 
outlined in this manual are not followed. ITT Goulds Pumps will not accept responsibility for physical injury, 
damage or delays caused by a failure to observe the instructions in this manual and the IOM provided with your 
equipment.

damage. Lift equipment only at specifically identified lifting points or as 
instructed in the current IOM. Current manuals are available at

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.
