Baseplate Grout Alternate bolt and washer Concrete Bolt sleeve Figure 10: Bolt installation 4.2 Set the baseplate Pumps are checked at the factory for the ability to be aligned to the required tolerances. Due to the flexi- bility of an ungrouted base and handling in shipment, do not assume that the unit is in alignment when it is placed on the rough foundation.
4.3 Pump-to-driver alignment Do not reconnect the non-flexible coupling until after you complete the alignment operation. The baseplate does not need to be level. After the foundation bolts are lightly torqued, recheck the alignment requirements. If the alignment must be corrected, then add or remove shims or wedges under the baseplate. 4.3 Pump-to-driver alignment Precautions WARNING:...
4.3 Pump-to-driver alignment Initial alignment (cold alignment) checks When Before you grout the baseplate This ensures that alignment can be accomplished. After you grout the baseplate This ensures that no changes have occurred during the grouting process. After you connect the piping This ensures that pipe strains have not altered the alignment.
4.3 Pump-to-driver alignment Feeler gauge Figure 11: Incorrect angular alignment Straight edge Figure 12: Incorrect parallel alignment Straight edge Feeler gauge Figure 13: Correct alignment 4.3.3 Align the pump using a dial indicator Before you begin, you must have a dial indicator with a mounting magnet and extension bars. A dial indicator can provide more accurate alignment than a straight edge.

6.3 Bearing maintenance NOTICE: Risk of equipment damage. Ensure that the grease container, the greasing device, and the fit- tings are clean. Failure to do so can result in impurities entering the bearing housing while re- greasing the bearings. Relief plug Fitting Figure 35: Grease lubricated bearings Wipe dirt from the grease fittings.
6.3 Bearing maintenance • ShellAlvania EP-2 Requirements Keep the following points in mind when lubricating with grease: • Grease must be of sodium or lithium base with a NLGI-2 consistency. Do not use graphite. • Greases made from animal or vegetable oils are not recommended due to the danger of deteriora- tion and forming of acid.
6.4 Shaft-seal maintenance Blow-dry the bearings with air that is clean, filtered, and compressed. Hold the two races together but allow the inner race to rotate a few turns now and then to dislodge the kerosene from the retainer pockets. When the bearings are dry, oil the bearings immediately with a good grade of clean machine oil to prevent corrosion or rust.
6.5 Disassembly Check or instruction Explanation/comment the stuffing box. Never reuse old packing or add new rings to old packing. Clean the stuffing box thoroughly before you install new packing. Check the condition of the shaft or sleeve for — possible scoring or eccentricity and make re- placements as necessary.
6.5 Disassembly • Handling heavy equipment poses a crush hazard. Use caution during handling and wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes, gloves, etc.) at all times. • Precautions must be taken to prevent physical injury. The pump may handle hazardous and/or toxic fluids.
6.5 Disassembly Slightly spread the bottom apart. Lift upwards. Item Description Annular groove Coupling guard half Driver Remove the remaining nut, bolt, and washers from the pump half of the coupling guard. It is not necessary to remove the end plate from the pump side of the bearing housing. You can access the bearing-housing tap bolts without removing this end plate if maintenance of internal pump parts is necessary.
6.5 Disassembly If the unit is oil-lubricated, then remove the reservoir bottle and oil drain plugs from the bottom of the bearing housings and drain the oil. Replace the plugs after draining. Remove the glands from the casing. • If the pump has packed stuffing boxes, then remove the nut from the stud, and then remove the gland halves.
6.5 Disassembly NOTICE: Do not remove bearings from the shaft unless you need to replace them.
