1.5 ATEX Considerations and Intended Use
Special care must be taken in potentially explosive environments to ensure that the equipment is proper-
ly 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. 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 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:

The CE and the Ex designate the ATEX compliance. The code below reads as follows:

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.
ISO 80079-37:2016 Section 5.7
Recommended bearing replacement interval (based on L10 life) = 17,520 hours of operation.
