  • Page 13: Location

    2.3 Location 2.3 Location 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.

  • Page 14: Installation - Horizontal Pumps

    2.5 Installation - horizontal pumps 2.5 Installation - horizontal pumps Bedplate mounted units are normally mounted on a concrete foundation of liberal thickness poured on a solid footing, using a one-three-five mix. The foundation should be substantial in order to absorb any vi- bration and to form a permanent, rigid support for the pumping unit.

  • Page 15: Alignment Procedures

    2.6 Alignment procedures Figure 5: By adjustment of wedges, bring the bedplate to an approximate level and provide the proper dis- tance above the foundation for grouting ( ¾" to 1½"). Level or plumb the suction and discharge flanges. Bring pump and motor shafts into reasonable alignment making absolutely certain that motor shaft is not above pump shaft or if it is, that there is a sufficient thickness of shims under the motor feet to allow for adjustment during alignment Tighten foundation bolts, but only finger tight.
  • Page 16 2.6 Alignment procedures NOTICE: Alignment in one direction may alter alignment in another. Check through each alignment pro- cedure after making any alignment alteration. Parallel alignment Unit is in parallel misalignment when the shaft axes are parallel but not concentric. Shift driver as re- quired.

    2.7 Piping - general Place a dial indicator on one shaft hub and rotate that hub 360°. Take readings from the face of the other hub. Alignment is achieved when indicator does not deflect more than .002". See Fig. Figure 13: Dial indicator 2.7 Piping - general All piping must be supported independently of the pump.

  • Page 20: Piping - Suction

    2.8 Piping - suction Figure 14: 2.8 Piping - suction General Properly installed suction piping is of extreme importance for trouble-free centrifugal pump operation. Use of elbows close to the pump suction flange should be avoided. Where used, elbows should be long radius.
  • Page 21 2.8 Piping - suction Figure 16: A centrifugal pump should never be throttled on the suction side. Suction strainers, when used, should have a net "free area" of at least three times the suction pipe area. Separate suction lines should be used when more than one pump is operating from the same source of supply.

  • Page 22: Piping - Discharge

    2.9 Piping - discharge Figure 18: The velocity of the water approaching the pump suction pipe should be kept to a maximum of one foot per second to avoid air being drawn into the pump. Pump suction inlet velocities and submergence (the height of the water above the pump inlet) are two additional factors that must be considered.

  • Page 23: Connection Of Piping

    2.10 Connection of piping Increasers, if used in discharge line, should be placed between the pump and check valves. If quick-closing valves are installed in the system, cushioning devices should be used to protect the pump from surges and water hammer. 2.10 Connection of piping Connect suction and discharge piping to the pump.

  • Page 24: Preparation For Operation

    3 Preparation for operation 3 Preparation for operation 3.1 Pump bearings Oil lubrication Oil lubricated pumps are not lubricated at the factory. A high quality turbine type oil, with rust and oxidation inhibitors, should be used. Constant level oilers are supplied with most oil lubricated pumps.

  • Page 25: Driver Bearings And Coupling

    Driver bearings and coupling The pump steady bearings (below the pump support plate) are sleeve type and made of various materi- als depending upon the application of the pump. Refer to 6.1 Lubrication on page 36 for specific details. Close-coupled pumps Close-coupled pumps contain no pump bearings.
  • Page 26 3.3 Stuffing boxes Figure 21: To pack the stuffing box, install the packing and lantern ring in the proper sequence. Each ring should be installed separately. Firmly seat each ring. Use of a wooden split bushing is recommended. See Fig. 22. Use gland to jack the bushing and ring into the box.

    3.4 Connection of sealing liquid or grease lubricator (packed box) CAUTION: Connection of sealing liquid or grease lubricator (packed box) If the stuffing box pressure is above atmospheric pressure, and the pumpage is clean, normal gland leak- age of 40 to 60 drops per minute is usually sufficient to lubricate and cool the packing and sealing liquid is not required.

  • Page 28: Connection Of Drain Piping

    3.6 Connection of drain piping Bearings Bearing cooling is available on some units. When it is available, cooling water must be connected to the jacket when pumping hot liquids. See the temperature limits listed under Construction Details in 6.4 Sec- tional View and Parts List on page 41.

  • Page 29: Connection Of Equalizing Piping

    3.7 Connection of equalizing piping 3.7 Connection of equalizing piping Some multi-stage pumps have equalizing piping to equalize pressure on the stuffing boxes (see 6.4 Sec- tional View and Parts List on page 41. This piping is in the box of fittings which accompanies the pump. The ends of the piping must be connected to the openings in each stuffing box.

If element rubs or binds: Check alignment Pipe loads should be removed Check impeller clearance (if external adjustment is possible) as outlined in Impeller clearance ad- justment.
  • Page 31 4.3 Priming Close air vent valves, start pump and open discharge gate valve. Pump will continue to be primed for any future starting. This method is the simplest and, particularly for automatic operation, the safest. A float switch in the suc- tion reservoir can be arranged to stop pump, should there be failure of liquid supply.
  • Page 32 4.3 Priming In either of these methods (1) and (2) , the pump will remain primed, provided foot valve is tight. Any failure, however, of foot valve when pump is standing idle, will permit the pump to lose its prime. During long idle periods, the pump can also lose its prime through leakage from stuffing boxes.

  • Page 33: Initial Inspection After Starting

    4.4 Initial inspection after starting Figure 27: Priming by automatic primer pump Where there is a fluctuating suction lift that occasionally might drop below the normal limits of the pump, or for installations where there is any quantity of air entrained in the pumpage, the system shown in Fig. 28 is very well adapted.

    4.5 Alignment - final Mechanical seal The mechanical seal was adjusted at the factory. If the seal leaks slightly when pump is first started, a few Some units do not require doweling since lock washers are furnished which hold the pump and driver feet securely in place.
  • Page 35 4.6 Doweling On units to be doweled (except those noted above), drill through two diagonally opposite feet of the pump into the bedplate. Use a reamer with a ¼" per foot taper. The dowels should extend well into the bedplate but project above the pump feet. Drivers should also be doweled but the driver manufacturer should be contacted for instructions.

  • Page 36: Operation

    5 Operation 5 Operation 5.1 Stuffing box Stuffing boxes with packing rings - less quenching liquid or grease lubricator: Periodically inspect stuffing box to see that there is sufficient leakage to lubricate the packing and maintain a cool box. Never draw up packing so that the stuffing box heats, as this will cause damage to both packing and sleeve.

  • Page 37: Operating At Reduced Head

    5.3 Operating at reduced head also is insurance against damage due to running the pump against a closed discharge valve or very low flow conditions. Bearing temperature relay which will shut the unit down if the bearing temperature exceeds a predetermined maximum.
