SAFETY WARNINGS
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.
WARNING
A pump is a pressure vessel with rotating parts that can be hazard o us. An y press ure vessel can explode,
rupture, or discharge its contents if sufficiently ove r press u r i zed causi n g deat h, personal injury, property
damage, and/or damage to the environment. All necessary measures must be taken to ensure over
pressurization does not occur.
WARNING
Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.
Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and
result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is
avoided.
WARNING
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump
and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but
are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.
WARNING
Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for
disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers
and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly
expand and result in a violent explosion and injury.
ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to
observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the
current IOM available at www.gouldspumps.com/literature.
