WARNING
Noise:
Sound pressure levels may exceed 80 dbA in operating process plants. Clear
visual warnings or other indicators should be available to those entering an
area with unsafe noise levels. Personnel should wear appropriate hearing pro-
tection when working on or around any equipment, including pumps. Consider
limiting personnel’s exposure time to noise or, where possible, enclosing
equipment to reduce noise. Local law may provide specific guidance regard-
ing exposure of personnel to noise and when noise exposure reduction is re-
quired.
WARNING
Temperature:
Equipment and piping surfaces may exceed 130ºF (54ºC) in operating proc-
ess plants. Clear visual warnings or other indicators should alert personnel to
surfaces that may reach a potentially unsafe temperature. Do not touch hot
surfaces. Allow pumps operating at a high temperature to cool sufficiently be-
fore performing maintenance. If touching a hot surface cannot be avoided,
personnel should wear appropriate gloves, clothing, and other protective gear
as necessary. Local law may provide specific guidance regarding exposure of
personnel to unsafe temperatures.

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:
Description of Ex-Directives
The Ex-directives are a specification enforced in Europe and the United Kingdom for electrical and non-
electrical equipment installed in those locations. Ex-directives deal with the control of potentially explo-
sive atmospheres and the standards of equipment and protective systems used within these atmos-
pheres. The relevance of the Ex-requirements is not limited to Europe or the UK. You can apply these
guidelines to equipment installed in any potentially 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 liquid end temperature.
2.
Maintaining proper bearing lubrication.
3.
Ensuring that the pump is operated in the intended hydraulic range.
The Ex conformance is only applicable when the pump unit is operated within its intended use. Operat-
ing, 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.
