W A R N I N G

Your pump was carefully selected, sized, manufactured and inspected with the utmost care to provide safe and re li able ser vice, at the best pos si ble ef fi ciency to suit your spe cific pump ing re qui re ments. In the in ter est of trouble free pump operation and safety of operating personnel, the following safety precaution should be strictly adhered to.

1.READ AND FOLLOW CAREFULLY ALL RECOMMENCED PROCEDURES, as described in your operator’s manual, for storage, installation, start-up, operation and maintenance of your pump and related auxiliary equipment such as motor, variable speed drive, gear reducer, v-belt, coupling, etc.

2.DRIVER ROTATION MUST BE CHECKED before first start-up and before the v-belts are installed or the coupling halves are connected. Severe equipment damage and injury to personnel may occur if the pump is driven in the opposite direction to the arrow of rotation cast on the pump casing.

3.DO NOT ALTER THE ORIGINAL OPERATING CONDITIONS of the pump without first consulting with your local ITT Industries - Goulds Pump representative. The operation of the pump at conditions other than

those for which it was designed may result in equipment damage and injury to operators.

4. DO NOT OPERATE THE PUMP AT LOW OR ZERO FLOW CONDITIONS. All operating conditions which could cause the pumped liquid to vaporize are dangerous, such as clogged suction and discharge piping, shut-off suction and discharge valves, etc. Vapor pressure build-up could cause the pump casing and system piping to explode resulting in severe equipment damage and personal injury.

5.DO NOT USE HEAT TO AS SIST IN IM PEL LER RE MOVAL from the shaft when servicing the pump. Heat can cause vaporization of fluid which may be trapped in the impeller hub resulting in an ex plo sion which could cause personal injury and equipment damage.

6.DO NOT OPERATE THE PUMP WITHOUT PROPERLY INSTALLED V-BELT OR COUPLING GUARD. Failure to install guards may result in personal injury.

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 www.gouldspumps.com/literature_ioms.html or by contacting

your nearest Goulds Pumps sales representative.

These manuals must be read and understood before installation and start-up.

For additional information, contact your nearest Goulds Pumps sales representative or visit our Web site at www.gouldspumps.com.

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 hazardous. Any pressure vessel can explode, rupture, or discharge its contents if sufficiently over pressurized causing death, 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.
