DEFINITIONS
This pump has been designed for safe and reliable
operation when properly used and maintained in
accordance with instructions contained in this manual.
A pump is a pressure containing device with rotating
parts that can be hazardous. Operators and
maintenance personnel must realize this and follow
safety measures. ITT Industries - Goulds Pumps
shall not be liable for physical injury, damage or
delays caused by a failure to observe the instructions
in this manual.
Throughout this manual the words WARNING,
CAUTION, and NOTE are used to indicate
procedures or situations which require special
operator attention:
s
!WARNING
Warning is used to indicate the presence of a
hazard which can cause severe personal injury,
death, or substantial property damage if the
warning is ignored.
$CAUTION
Caution is used to indicate the presence of a
hazard which will or can cause minor personal
injury or property damage if the warning
is ignored.
!NOTE: If equipment is to be installed in a
potentially explosive atmosphere and these
procedures are not followed, personal injury
or equipment damage from an explosion may
result.
"NOTE: Particular care must be taken when
the electrical power source to the equipment
is energized.
NOTE: Operating procedure, condition, etc.
which is essential to observe.
EXAMPLES
s
!WARNING
Pump shall never be operated without coupling
guard installed correctly.
$CAUTION
Throttling flow from the suction side may cause
cavitation and pump damage.
!NOTE: Improper impeller adjustment could
cause contact between the rotating and
stationary parts, resulting in a spark and heat
generation.
"NOTE: Lock out driver power to prevent
electric shock, accidental start-up and
physical inury.
NOTE: Proper alignment is essential for long
pump life.

GENERAL PRECAUTIONS
s
!WARNING
Personal injuries will result if procedures
outlined in this manual are not followed.
As!NEVER operate pump without coupling
guard correctly installed.

EXPLOSION PREVENTION
!In order to reduce the possibility of accidental explosions in atmospheres containing explosive
gasses and/or dust, the instructions under the ATEX symbol must be closely followed. ATEX
certification is a directive enforced in Europe for non-electrical and electrical equipment installed in
Europe. ATEX requirements are not restricted to Europe, and are useful guidelines for equipment
installed in any potentially explosive environment.
SPECIAL ATEX CONSIDERATIONS
All installation and operation instructions in this
manual must be strictly adhered to. In addition, care
must be taken 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. maintining proper bearing lubrication
3. ensuring that the pump is operated in the
intended hydraulic range
83700-10th IOM 12/04

ATEX IDENTIFICATION
For a pumping unit (pump, seal, coupling, motor and
pump accessories) to be certified for use in an ATEX
classified environment, the proper ATEX identification
must be present. The ATEX tag will be secured to the
pump or the baseplate on which it is mounted. A
typical tag will look like this:
The CE and the Ex designate the ATEX compliance.
The code directly below these symbols reads as
follows:
II = Group 2
2 = Category 2
G/D = Gas and Dust present
T4 = Temperature class, can be T1 to T6
(see following table 1)
Table 1
Code
Max permissible
surface temperature,
°F (°C)
Max permissible
liquid temperature,

T1 842 (450) 700 (372)
T2 572 (300) 530 (277)
T3 392 (200) 350 (177)
T4 275 (135) 235 (113)
T5 212 (100) Option not available
