ATEX Considerations and Intended Use
Special care must be taken in potentially explosive environments to ensure that the equipment is properly maintained. This
includes but is not limited to:
1.
Monitoring the pump frame and liquid end temperature.
2.
Maintaining proper bearing lubrication.
3.
Ensuring that the pump is operated in the intended hydraulic range.
The ATEX conformance is only applicable when the pump unit is operated within its intended use. Operating, installing
or maintaining the pump unit in any way that is not covered in the Instruction, Operation, and Maintenance manual (IOM)
can cause serious personal injury or damage to the equipment. This includes any modification to the equipment or use of
parts not provided by ITT Goulds Pumps. If there is any question regarding the intended use of the equipment, please
contact an ITT Goulds representative before proceeding. Current IOMs are available at
www.gouldspumps.com/literature_ioms.html or from your local ITT Goulds Pumps Sales representative.
All pumping unit (pump, seal, coupling, motor and pump accessories) certified for use in an ATEX classified environment,
are identified by an ATEX tag secured to the pump or the baseplate on which it is mounted. A typical tag would look like
this:

For variable speed motor applications
–
Electric motor must be specified with shaft grounding and flexible coupling

The code classification marked on the equipment must be in accordance with the specified area where the equipment will
be installed. If it is not, do not operate the equipment and contact your ITT Goulds Pumps sales representative before
proceeding.
