Page 5: General Information
This pump 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 acknowledgment, without written permission of Goulds Pumps, Inc. Receiving inspection - shortages Care should be taken when unloading pumps. -
Page 6: Installation
Installation Installation This section is a general installation and operating instruction for most Goulds pumps. Specific text and illustrations are included in this section. To insure pump performance and operating life, proper installation and reasonable maintenance are required. The following instructions are a guide for installation and maintenance personnel and the pump operator. -
Page 7: Piping Support
To secure the shims in place and provide a level surface for the base or plate, grout is poured over the concrete foundation. A 19mm to 38mm | ¾" to 1-½" grout allowance is recommended. Model JC Installation, Operation and Maintenance Instructions... -
Page 8: Install Pump, Driver, And V-Belt Drive
Before installing the driver onto an overhead motor mount or side-by-side base, ensure that Foundation requirements and baseplate mounting procedures sections are complete. NOTICE: Alignment procedures must be followed to prevent unintended contact of rotating parts. Follow coupling manufacturer’s installation and operation procedures.

Page 9: Install And Tension The Belt
2. After the belts are seated in the sheave grooves, increase the center distance between the pump and motor shafts to tension the belts. Model JC Installation, Operation and Maintenance Instructions... -
Page 10: Pump-Driver Alignment
The unit will be in angular alignment when the measurements show that the coupling faces are the same distance apart at all points Checking angular alignment. Model JC Installation, Operation and Maintenance Instructions... - Page 11 When the units are lined up cold, it may be necessary to make an allowance for the vertical rise of the driver and/or pump caused by heating. Goulds Pumps recommendations should be obtained and followed. Model JC Installation, Operation and Maintenance Instructions...

Page 12: Alternate Method Of Alignment
• Springing of the baseplate by heat from an adjacent steam pipe or from a steam turbine. • Shifting of the building structure due to variable loading or other causes. • Loose nuts or bolts on the pump or driver assembly. Model JC Installation, Operation and Maintenance Instructions... -
Page 13: Operation
Original equipment packing is a suitable grade for the service intended. To replace original packing, contact your local Goulds representative. Refer to Bill of Material and Assembly Drawing for specific packing size and configuration. Model JC Installation, Operation and Maintenance Instructions... -
Page 14: Packing Procedure
Failure to properly locate seal cage will result in insufficient packing lubrication. Packing and shaft sleeve damage will occur. 8. After packing and seal cage are properly installed, insert gland into stuffing box. Tighten gland nuts finger-tight only. Shaft should turn freely. Model JC Installation, Operation and Maintenance Instructions... -
Page 15: Mechanical Seals
Special seal information and replacement seal elements should be provided by the seal manufacturer. Goulds strongly recommends the stocking of replacement sealing elements. CAUTION: Do not make shaft adjustments on mechanical seal installations without consulting seal instructions and pump assembly drawing. Model JC Installation, Operation and Maintenance Instructions... -
Page 16: Pump Start-Up
The direction of rotation of the pump is indicated in a prominent location. For pumps with impellers threaded on the shaft, reverse rotation would back the shaft from the impeller thread. Considerable damage may occur. Lock out driver power to prevent electric shock, accidental start-up and physical injury. Model JC Installation, Operation and Maintenance Instructions... -
Page 17: Lubricating Lines To Stuffing Box
• Mechanical binding or rubbing of rotating element. • Pumpage specific gravity and/or viscosity too high CAUTION: Always vary capacity with regulating valve in the discharge line. NEVER throttle flow from the suction side Model JC Installation, Operation and Maintenance Instructions... - Page 18 Inspection intervals should be shortened appropriately if the pumpage is abrasive and/or corrosive, or if the environment is classified as potentially explosive. WARNING: DO NOT apply heat to hub or nose of threaded impeller. There is a danger of explosion. Model JC Installation, Operation and Maintenance Instructions...

3. Remove suction disc (182) and suction disc liner (100B) from casing fit. 4. Impeller (101) is threaded onto shaft (122). Remove impeller by restraining coupling end of shaft and turning impeller in the operating direction of rotation. Do not apply heat. Model JC Installation, Operation and Maintenance Instructions... -
Page 20: To Assemble The Liquid End
The “J” type bearing assembly uses medium-heavy ball bearings. On the small size “J” bearings, double row ball bearings are used for combined loading. The larger sizes utilize separate radial and thrust ball bearings. Adjustment of nose clearance can be easily accomplished without bearing disassembly. Model JC Installation, Operation and Maintenance Instructions... -
Page 21: Impeller Clearances
Moving shaft (122) toward suction side casing liner will decrease the clearance 2. To decrease impeller clearance, loosen outboard jam nut and drive the shaft assembly by turning the inboard jam nut. Model JC Installation, Operation and Maintenance Instructions... -

B.B., Tellus 41 or equal. However, a good grade of #30 or #40 weight is satisfactory for normal temperatures. For best results, the weight of the oil lubricant should be adjusted for the normal operating temperature as follows: To 60°C | 150ºF SAE 20 To 71°C | 160ºF SAE 30 Model JC Installation, Operation and Maintenance Instructions... -
Page 23: Grease Lubrication
NOTICE: The shaft seals above each bearing should be oiled with a few drops of #30 oil before the pump is started to ensure lubrication of the seal lip. Model JC Installation, Operation and Maintenance Instructions... - Page 24 93°C | 200ºF, which will be the normal temperature for that installation. Higher temperatures than this normal temperature, without any change in speed or loading, can mean a lubrication difficulty or the approach of a bearing failure.

Page 25: To Disassemble The "J" Bearing
Preventive Maintenance To disassemble the “J” bearing For the purpose of these instructions, assume the JC liquid end has been disassembled, including suction disc (182), suction disc liner (100B), impeller (101), casing (100), hub disc (184), stuffing box components, and shaft sleeve (126). - Page 26 (332) in retainer (119B). As the thrust bearing housing (134A) enters the bearing frame bore, align adjusting lugs on the frame and housing. 6. Loosely install adjusting studs (356A) in adjusting lugs. Do not tighten. 7. Install radial bearing slinger (123C). Model JC Installation, Operation and Maintenance Instructions...

Page 30: Appendix
To meet the high demand for waterless sealing of stuffing boxes in slurry pumps, Ashland Operations/Goulds has added an expeller to the JC line. Using its basic bearing and wetted end configuration, the JC now incorporates a hub disc that has been enlarged to allow for the expeller option. - Page 31 Several shots of grease should be added to the stuffing box, as little as every three operating days or as much as every four operating hours, depending upon the severity of the pumpage abrasiveness. In addition, grease should be added prior to every tenth start-up. Model JC Installation, Operation and Maintenance Instructions...
