    3 Installation 3 Installation 3.1 Installation WARNING: • Equipment that will operate in a potentially explosive environment must be installed in ac- cordance with the following instructions. • All equipment being installed must be properly grounded to prevent unexpected static electric discharge.

  • Page 15: Foundation

    3.3 Foundation 3.3 Foundation The foundation must be a permanent, rigid support for the subbase or floorplate. It should be an industri- ally accepted design capable of absorbing excessive vibration. Foundations are typically concrete with anchor bolts cast in to secure the pump. An anchor bolt assembly consists of a bolt and washer with a sleeve 2-½...

    3.4 Install pump, driver, and v-belt drive Mount and fasten the pump on the pedestal spacer, foundation, or baseplate as applicable. Use appropriate hardware. For a motor that is mounted overhead, install the overhead motor mount. For a motor that is mounted to the side of the pump, fasten the motor slide base on the baseplate or pump.

    3.5 Pump-driver alignment Figure 6: V-belt tension Many v-belt drive manufacturers offer tension measurement tools that can aid in setting proper belt tension. Contact the v-belt drive manufacturer for more information. Secure the overhead motor mount on slide base in place once the belts are properly tensioned. Install the unit after installation to ensure that the belts and sheaves do not come into contact with the guard.
  • Page 19 3.5 Pump-driver alignment Figure 7: Checking angular alignment A check for parallel alignment is made by placing a straight edge across both coupling rims at the top, bottom, and at both sides. The unit will be in parallel alignment when the straight edge rests evenly on the coupling rim at all positions.

  • Page 20: Alternate Method Of Alignment

    3.5 Pump-driver alignment 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 fol- lowed. 3.5.3 Alternate method of alignment An approved method for putting the coupling halves in final accurate alignment is by the use of a dial indicator.

  • Page 21: Preparation For Shipment

    3.6 Preparation for shipment • 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. 3.6 Preparation for shipment Goulds pumps are prepared at the factory for shipment under covered conditions.

  • Page 22: Operation

    4 Operation 4 Operation 4.1 Preparation for start-up 4.1.1 Stuffing boxes In the conventional stuffing box, mechanical seals and packing seal between the stationary and rotating components of the pump. Generally, a clear liquid such as water is forced through the stuffing box to lu- bricate the sealing elements.

  • Page 23: Packing Procedure

    4.2 Packing procedure Packing (106) Lantern ring (105) Shaft sleeve (126) Stuffing box cover (184) Gland (107) Shaft (122) Figure 10: Typical stuffing box 4.2 Packing procedure Stuffing box and shaft sleeve must be clean and free of grit. Form packing over shaft or mandrel of same diameter. Carefully cut to packing length. Discard rings cut too short.

  • Page 24: Mechanical Seals

    4.2 Packing procedure After packing and seal cage are properly installed, insert gland into stuffing box. Tighten gland nuts finger-tight only. Shaft should turn freely. NOTICE: Do not over tighten gland nuts. Packing may set permanently and require removal. Over tight- ened packing causes excessive friction between packing and sleeve, and will result in dam- aged components.

    4.5 Locating problems WARNING: Lock out driver power to prevent electric shock, accidental start-up and physical injury. WARNING: When installing in a potentially explosive environment, ensure that the motor is properly certi- fied. 4.4.4 Lubricating lines to stuffing box Lubricating liquid must be flowing to the stuffing box before the pump is started. Both mechanical seals and packing require lubrication for continuous service.
  • Page 27 4.5 Locating problems • Mechanical binding or rubbing of rotating element. • Pumpage specific gravity and/or viscosity too high WARNING: • Do not operate pump below minimum rated flows or with suction and/or discharge valve closed. These conditions may create an explosive hazard due to vaporization of pumpage and can quickly lead to pump failure and physical injury.
  • Page 28 4.5 Locating problems • Cavitation–Damage to internal surfaces of pump • Observe pump for vibration levels, bearing temperature and excessive noise. If normal levels are exceeded, shut down and resolve. Model JC Installation, Operation and Maintenance Instructions...

    5.3 Liquid end WARNING: When handling hazardous and/or toxic fluids, proper personal protective equipment should be worn. If pump is being drained, precautions must be taken to prevent physical injury. Pumpage must be handled and disposed of in conformance with applicable environment regulations. Remove cap screws or bolts which fasten suction disc (182)to casing (100).

  • Page 36: To Disassemble The "J" Bearing

    5.6 Maintenance of Bearings The running temperature for a bearing assembly depends on many factors such as speed, bearing loads, ambient air temperature, and condition of bearings. Temperatures higher than the human hand can tolerate are very satisfactory for good bearing operation and should not cause alarm. For a given speed and loading, the bearing housing temperature will stabilize at some temperature, usu- ally below 93°C | 200ºF, which will be the normal temperature for that installation.
  • Page 37 5.6 Maintenance of Bearings Install lockwasher (382) and locknut (136) before bearings cool. When bearings cool to room temperature, retighten locknut and secure with lockwasher tang. To install thrust bearing housing (134A): Double row ball thrust bearing: Lubricate seal (332) and O-ring (496) on thrust bearing housing (134A). Carefully slide housing (134A) onto shaft (122) over thrust bearing.
