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.
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.

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.
2 Introduction 2 Introduction 2.1 Introduction This instruction manual is intended to assist those involved with the installation, operation, and mainte- nance of Goulds Model 3335 Multi-Stage Pumps. It is recommended that this manual be thoroughly re- viewed prior to installing or performing any work on the pump or motor. 3335 Installation, Operation and Maintenance Instructions...
3 General 3 General 3.1 Importance of instructions The design, material, and workmanship incorporated into the construction of Goulds pumps make them capable of giving long, trouble-free service. The life and satisfactory service of any mechanical unit, how- ever, are enhanced and extended by correct application, proper installation, periodic inspection, and careful maintenance.
4 Installation 4 Installation 4.1 General Pumping unit should be placed as close as practical to the source of supply. Floor space and head room allotted to the unit must be sufficient for inspection and maintenance. Be sure to allow for crane or hoist service.

4.3 Alignment procedures Figure 1: Dial indicator method Parallel Alignment - Straight Edge Method Place a straight edge across both coupling hubs at four points 90° apart. Use a feeler gauge to measure the amount of misalignment at each of the four points. Make alignment corrections by moving driver side to side or by shimming it up or down.
4.4 Rotation check and connection of coupling 4.4 Rotation check and connection of coupling Before coupling is connected, jag motor to check for correct rotation. Motor rotation should be counter- clockwise when viewed from coupling end. If electric power is not available, do not connect coupling until correct rotation has been verified.
5 Operation 5 Operation 5.1 Start-up check Rotate pump shaft by hand to be sure it is free. If pump cannot be turned by hand, or binding and rub- bing are noticed, correct before starting. Insure that alignment and rotation procedures in Installation sec- tion have been followed.
6 Preventative and Corrective Maintenance 6 Preventative and Corrective Maintenance 6.1 Lubrication Refer to 4.5 Lubrication on page 10 for lubrication procedures for pump. Oil should be renewed at 3 month intervals. Follow motor and coupling manufacturer's lubrication instructions. 6.2 Mechanical seal The seal requires no attention other than to make sure that circulation lines, where installed, do not be- come clogged.
7 Disassembly and Reassembly 7 Disassembly and Reassembly 7.1 Disassembly of pump Lock out power source. Shut off valves controlling flow to and from pump. Disconnect piping. Uncouple pump. See coupling manufacturer's instructions for removal. Drain oil through oil drain plug on bottom of bearing frame (228A) Drain pump through plug (408A)in bottom of casing adapter.
7.3 Reassembly of power end Shaft (122) Check shaft for runout to be sure it is not bent. Bearing seats, retaining ring grooves, Keyways, surfaces under oil seals, and surface under mechanical seal should be in good condition. Mechanical Seal (383) Replace if faces are worn, scarred, or cracked, or if elastomeric bellows is damaged.

7.4 Reassembly of liquid end Slide rotary unit of mechanical seal (383A) over splined end of pump shaft (122) and against retain- ing ring (361D). Use care to avoid cutting rubber bellows on splined teeth. With bearing frame assembly remounted on support structure in the vertical position, bolt casing adapter (108) to end cover (109C), install O-ring (412K).

7.4 Reassembly of liquid end Figure 6: Move diffuser up and down Figure 5: Move diffuser up and down 10. Proper location of the impellers on the shaft is obtained by the use of shims (331) between the drive collar and the first stage impeller hub, and also between the hubs of the remaining impellers. Shins are supplied in .010"...
