requirements is not limited to Europe. You can apply these guidelines to equipment installed in any po-
tentially explosive atmosphere.
Guidelines for compliance
Compliance is fulfilled only when you operate the unit within its intended use. Do not change the condi-
tions of the service without the approval of an ITT representative. When you install or maintain explosion
proof products, always comply with the directive and applicable standards (for example, IEC/EN
60079-14).
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. Oper-
ating, 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 in-
cludes 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 https://www.gouldspumps.com/en-US/Tools-and-Resources/Literature/
IOMs/ 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 classi-
fied 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:
