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:

!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

!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.

3700-10th IOM 12/04 7

GENERAL PRECAUTIONS

!WARNING

Personal injuries will result if procedures

outlined in this manual are not followed.

As!NEVER operate pump without coupling

guard correctly installed.

conditions to which the pump was sold.

NEVER start pump without proper prime

(sufficient liquid in pump casing).

NEVER run pump below recommended

minimum flow or when dry.

CBALWAYS lock out power to the driver before

performing pump maintenance.

CNEVER operate pump without safety devices

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)
