IMPORTANT SAFETY NOTICE
To: Our Valued Customers
User safety is a major focus in the design of our products. Following the precautions outlined in this
manual will minimize your risk of injury.
ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and
operated.
Safe installation, operation, and maintenance of ITT Goulds Pumps equipment are an essential end user
responsibility. This Pump Safety Manual identifies specific safety risks that must be considered at all
times during product life. Understanding and adhering to these safety warnings is mandatory to ensure
personnel, property, and/or the environment will not be harmed. Adherence to these warnings alone,
however, is not sufficient — it is anticipated that the end user will also comply with industry and corporate
safety standards. Identifying and eliminating unsafe installation, operating and maintenance practices is
the responsibility of all individuals involved in the installation, operation, and maintenance of industrial
equipment.
Please take the time to review and understand the safe installation, operation, and maintenance guidelines
outlined in this Pump Safety Manual and the Instruction, Operation, and Maintenance (IOM) manual.
Current manuals are available at
your nearest Goulds Pumps sales representative.
www.gouldspumps.com/literature_ioms.html or by contacting

SAFETY WARNINGS
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.
WARNING
A pump is a pressure vessel with rotating parts that can be hazard o us. An y press ure vessel can explode,
rupture, or discharge its contents if sufficiently ove r press u r i zed causi n g deat h, personal injury, property
damage, and/or damage to the environment. All necessary measures must be taken to ensure over
pressurization does not occur.
WARNING
Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.
Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and
result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is
avoided.
WARNING
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump
and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but
are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.
WARNING
Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for
disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers
and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly
expand and result in a violent explosion and injury.
ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to
observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the
current IOM available at www.gouldspumps.com/literature.

Operating pump in reverse rotation may result in contact of metal parts, heat
generation, and breach of containment.
Lock out driver power to prevent accidental start-up and physical injury.
The impeller clearance setting procedure must be followed. Improperly setting
the clearance or not following any of the proper procedures can result in sparks,
unexpected heat generation and equipment damage.
If using a cartridge mechanical seal, the centering clips must be installed and set
screws loosened prior to setting impeller clearance. Failure to do so could result
in sparks, heat generation, and mechanical seal damage.
The coupling used in an ATEX classified environment must be properly certified
and must be constructed from a non-sparking material.
Never operate a pump without coupling guard properly installed. Personal injury
will occur if pump is run without coupling guard.
Make sure to properly lubricate the bearings. Failure to do so may result in excess
heat generation, sparks, and / or premature failure.
The mechanical seal used in an ATEX classified environment must be properly
certified. Prior to start up, ensure all points of potential leakage of process fluid to
the work environment are closed.
Never operate the pump without liquid supplied to mechanical seal. Running a
mechanical seal dry, even for a few seconds, can cause seal damage and must be
avoided. Physical injury can occur if mechanical seal fails.
Never attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.

INTRODUCTION
The Goulds Model 3500XD heavy duty stock pump is a
centrifugal pump designed to handle paper stock up to
approximately 16% O.D. consistency. The pump design
DESIGN CONCEPT
There are two major obstacles in pumping paper stock at
consistencies above 8% with a centrifugal pump: the
formation of a fiber network that will not readily flow, and
high air content which can cause air binding of a standard
centrifugal pump.
The Model 3500XD pump is normally attached to a suction
vessel or “standpipe,” and a constant level is maintained
above the suction centerline. An X-Ducer mounted on the
end of the pump shaft creates turbulence in the suction
incorporates special features to induce flow into the pump
suction and to remove air that is present in stock at higher
consistencies.
standpipe (Fig. 4, Zone 1), breaking up the fiber network
and separating air from the pulp. The pulp is then induced
to flow into the pump suction by the static head in the
standpipe and the pumping action of the X-Ducer. The
amount of turbulence required (minimum pump speed) as
well as the minimum standpipe level is a function of the
stock type, quality, consistency and temperature of each
specific application.
