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. Goulds pumps
shall not be liable for physical injury, damage or delays caused by a failure to observe the instructions in this manual.
The following symbols are used to denote special attention:
Electrical Hazard. Particular care must be taken when electrical power source to the equipment is
energized.
Warning. Operating procedure, practice etc which, if not correctly followed, could result in personal injury or
loss of life
Caution. Operating procedure, practice etc which if not followed could result in damage or destruction of
equipment

FOREWORD
This manual provides instructions for the Installation, operation, and maintenance of the
Goulds Axial Flow (AF) pump model. This manual covers the standard product. For special
options, supplemental instructions are supplied. This manual must be read and understood
before installation and start-up.
The design, materials and workmanship incorporated in the construction of Goulds pumps
makes them capable of giving long, trouble-free service. The life and satisfactory service of any
mechanical unit, however, is enhanced and extended by correct application, proper installation,
periodic inspection, condition monitoring and careful maintenance. This instruction manual was
prepared to assist operators in understanding the construction and the correct methods of
installing, operating, and maintaining these pumps.
Goulds shall not be liable for physical injury, damage or delays caused by a failure to
observe the instructions for Installation, Operation, and Maintenance contained in this
manual.
Warranty is valid only when genuine Goulds parts are used.
Use of the equipment on a service other than stated in the order will nullify the warranty,
unless written approval is obtained in advance from Goulds Pumps, Inc.
Supervision by an authorized Goulds representative is recommended to assure proper
installation.
Additional manuals can be obtained by contacting your local Goulds representative or by
calling 1-800-446-8537.

General Precautions
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
Never apply heat to remove impeller. It may explode due to trapped
liquid
Never use heat to disassemble pump due to risk of explosion from
trapped liquid
Never operate pump without coupling guard correctly installed
Never operate pump beyond the rated conditions to which the pump was
sold
Never start pump without proper prime, or proper liquid level in self
priming pumps
Never run pump below recommended minimum flow or when dry
Always lock out power to the driver before performing pump maintenance
Never operate pump without safety devices installed
Never operate pump with discharge valve closed
Never operate pump with suction valve closed
Do not change conditions of service without approval of an authorized
Goulds representative

AF (42-66) IOM 5
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:
II 2 G/D X
The CE and the Ex designate the ATEX compliance. The code directly below these symbols reads as follows:
II ------------ÆGroup 2
2 -------------ÆCategory 2
G/D ------------ÆGas and Dust present
X ------------ÆTemperature class, can be T1 to T6 (see following table)
Maximum Process Temperature to achieve desired T rating
T Rating per EN 1127-1 Maximum Surface
Temperature in Celsius Maximum Process Temperature in Celsius
T1 450 410
T2 300 260
T3 200165
T4 135 100
T5 100 65
T6 85 50
The code classification marked on the equipment should be in accordance with the specified area where the
equipment will be installed. If it is not, please contact your ITT/Goulds representative before proceeding.
Intended Use
The ATEX conformance is only applicable when the pump unit is operated within its intended use. All instructions
within this manual must be followed at all times. Operating, installing or maintaining the pump unit in any way that is
not covered in this manual can cause serious personal injury or damage to the equipment. This includes any
modification to the equipment or use of parts not provided by ITT/Goulds. If there is any question regarding the
intended use of the equipment please contact an ITT/Goulds representative before proceeding.

DEFINITIONS
Axial flow pumps are pressure-containing devices with
rotating parts that can be hazardous. It has been
designed for safe and reliable operation when properly
used and maintained in accordance with instructions
contained in this manual. It is not to be operated at
speeds, working pressures, discharge pressures, or
temperatures higher than, nor used with liquids other
than stated in the original order acknowledgement,
without written permission of ITT Industries, Gould’s
Pumps, Inc. Operators and maintenance personnel
must realize this and follow safety measures. ITT
Industries, Gould’s Pumps, Inc. shall not be liable for

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: Operating procedure, condition, etc. that is
essential to observe.
EXAMPLES WARNING
Pump shall never be operated without V-belt or
coupling guard installed correctly.
CAUTION
Obstructions to flow or pipe fowling may cause
cavitation and pump damage.
NOTE: Proper alignment is essential for long pump
life.
GENERAL PRECAUTIONS
WARNING
Personal injury will result if procedures outlined in
this manual are not followed.
xNever apply heat to remove the impeller. It may
explode due to trapped liquid.
xNever use heat to disassemble pump due to risk of
explosion from trapped liquid.
xNever operate pump without V-belt or coupling
guard correctly installed.
xNever operate pump beyond the rated conditions
to which the pump was sold.
xNever start pump without proper prime (sufficient
liquid in pump casing).
xNever run the pump < 75% or > 115% of the Best
Efficiency Point (B.E.P.), AF pumps are unstable in
these regions.
xAlways lock out power to the driver before
performing maintenance.
xNever operate pump without safety devices
installed.
