Page 6: Introduction And Safety
ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and operat- 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. -
Page 7: Safety
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 http://www.gouldspumps.com/literature. - Page 8 Lift equipment only at specifically identified lifting points or as instructed in the current IOM. Current manuals are available at www.gould- spumps.com/literature_ioms.html or from your local ITT Goulds Pumps sales representative. Note: Lifting devices (eyebolts, slings, spreaders, etc.) must be rated, selected, and used for the entire load being lifted.

1.5 Parts The use of genuine Goulds parts will provide the safest and most reliable operation of your pump. ITT Goulds Pumps ISO certifica- tion and quality control procedures ensure the parts are manufac- tured to the highest quality and safety levels. -
Page 11: Introduction
This design employs a combination static seal and second impeller to eliminate the conven- tional stuffing box. Seal water in the amount of 1/4-1/2 GPM is all that is required. The CW, CWR, and CWX are designated by the pump identification (Nameplate). The Pump Nameplate contains the following information: •... -

Page 23: Operation
If the pump does not prime properly, or loses prime during start-up, it should be shutdown and the condition corrected before the procedure is repeated. (Pumps moving high temperature liquids.) Open the warm-up valve to circulate liquid for preheating. Close the valve after the pump is warmed up. CWX Installation, Operation and Maintenance Instructions... -
Page 24: Operating Checks
Pumps that are shut down during freezing conditions should be protected by one of the following meth- ods. Drain the pump, remove all liquid from the casing. Keep fluid moving in the pump and insulate or heat the pump to prevent freezing. CWX Installation, Operation and Maintenance Instructions... -
Page 25: Field Tests
Lift Suction lift exists where the total suction head is below atmospheric pressure. Total suction lift is the reading of a liquid manometer at the suction nozzle of the pump, converted to feet of liquid, and referred to the datum minus the velocity head at the point of gage attachment.

Efficiency = Total head x gpm x specific gravity/3960 x Bhp 4.18 Trouble shooting Between regular maintenance inspections, be alert for signs of pump trouble. Common symptoms are listed in the following table. Correct any trouble immediately and avoid costly repair and shut down. CWX Installation, Operation and Maintenance Instructions... - Page 27 See item 5. 22. Air leaks in suction piping. See item 8. 23. Mechanical defects. See items 15 and 17. 24.
