    2 General Information 2 General Information 2.1 Preparation for shipment Goulds pumps are prepared at the factory for shipment under covered conditions. They are protected for transport and short term covered storage. Unless otherwise specified, it is assumed the pump will be in- stalled upon delivery.

Rectangular metal blocks and shims, or metal wedges having a small taper, are placed beside each anchor bolt to level the sub-base or floor-plate, see Figures below, Leveling with Wedges and Leveling with Blocks and Shims.

Angular and parallel misalignment are corrected by means of shims under the motor mounting feet. After each change, it is necessary to recheck the alignment of the coupling halves.

    2.4 Stuffing Boxes Alignment of gear type couplings Gear type couplings are aligned in the same manner as outlined above. However, the coupling covers must be moved back out of the way and measurements made on the coupling hubs as shown in Figure Gear Coupling Alignment.

Figure 9: Typical Stuffing Box Refer to 2.9 Bill of Material and Assembly Drawing on page 16 for specific packing size and configura- tion.

  • Page 16: Pump Start-Up

    2.5 Pump Start-up A significant amount of lubricating liquid should leak from gland side of stuffing box. Operate pump for at least 15 minutes before tightening gland nuts. Make small, even gland nut adjust- ments to reduce leakage. Allow adequate run-in time between adjustments. Acceptable leakage is 30-50 drops per minute.

  • Page 17: Water Hammer

    2.6 Water Hammer 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. Priming The pump must be completely primed before operation. 2.6 Water Hammer Water hammer is a high pressure surge within a closed pipe system, created by rapid change in the flow rate.

    3 Bearing Frame Assembly 3 Bearing Frame Assembly 3.1 General The inboard of lower bearing is an angular contact ball bearing with high thrust capacity and the out- board or top bearing is a high radial capacity ball bearing. Grease is the standard lubricant, but bearing assemblies can be furnished for oil lubrication.

  • Page 22: Liquid End

    4 Liquid End 4 Liquid End 4.1 General Instructions The impeller of the HS pump is recessed in a circular opening at the back of the casing. The uniform running clearance between the impeller and the casing keeps a uniform pressure around the outside of the impeller, and the resulting hydraulic forces on the impeller are low compared to the conventional cen- trifugal pump.

  • Page 23: Assemble The Liquid End

    4.4 Assemble the Liquid End The standard impeller has an impeller nut and drive key. Unscrew the impeller nut (right hand pump will have a right hand impeller nut) and then carefully pull the impeller off the end of the shaft. Remove the cap screws which fasten the stuffing box cover (184) to the bearing housing (134A).
