2.4 Pump storage requirements Examples Figure 1: Example of proper lifting method using lifting lugs 2.4 Pump storage requirements Requirements Submersible units require proper preparation for storage and regular maintenance during storage. The unit is considered in storage when it has been delivered to the job site and is awaiting installation. For specific requirements for storing motors, gearheads, engines, panels, sealing plans and other auxil- iaries, contact the equipment manufacturer.
15 minutes every two weeks. 2.5 Preservation and Storage ITT Goulds Pump Division's normal domestic shipping and storage preparation is suitable for protecting the pump during shipment in covered trucks. Although this is a submersible pump, storage in a clean, dry area will help preserve the paint and prevent corrosion.
NOTICE: The motor is rated for full horsepower with liquid temperatures of 104°F (40°C) or lower, unless noted otherwise on nameplate or ITT documentation. 3.4 Install the pump Make sure the lifting device is securely fastened to the motor lugs or hooks so the unit will not be dropped when it is lowered into the sump.
3.5 Slide rail system (optional) Position item #787G, sump flange adapter, as shown in section Y-Y and secure to base upright us- ing items #372K. Apply gasket adhesive to item #360W and place in section Y-Y and secure to base upright. Insert short-threaded end of stubs, items #787U, through base uprights and into the top two holes of the sump flange adapter, item #787G.
3.5 Slide rail system (optional) Remove items #371G and #357A and position lift cable loop between lifting brackets. Apply Loctite 271 and reinsert item #371G, hex head cap screw, through cable and lifting brackets and thread heavy hex nut, item #357A, and item #415A, jam nut, onto item #371G. Check cable clamps.. 3.5.4 Install the slide rail Refer to drawing B1-445153SLR and B2-445153SLR With anchor bolts in position, lower the base, item #787A, onto a flat, clean foundation and tighten...

4 Commissioning, Startup, Operation, and Shutdown 4 Commissioning, Startup, Operation, and Shutdown 4.1 Start the pump The most important concern is the prevention of motor overloading. Refer to the motor nameplate for full load ampere rating of the motor. Install an ammeter on the motor leads and check the motor draw immediately after the unit is start- NOTICE: A lower than expected current draw with a 3-phase motor may be an indication of incorrect ro- tation.
5 Maintenance 5 Maintenance 5.1 Maintenance 5.1.1 Maintenance - O-ring, pump flange to slide rail base flange Whenever the pump is removed from the sump using the slide rail system, the pump flange to slide rail base flange O-ring should be inspected for wear. If it does not appear to be in good condition, a replace- ment O-ring should be installed after the groove has been cleaned and dried so the adhesive will bond to the metal and rubber.
5.3 Pre-assembly CAUTION: • Avoid injury. Worn pump components can have sharp edges. Wear appropriate gloves while handling these parts. 5.2.2 Disassemble the pump Disconnect all electrical service. Mark leads for reassembly. Remove cap screws 370E that fasten suction cover to casing. Remove cover and suction cover lin- Remove impeller cap screw 370C.
5.4 Reassembly Inspect the casing for cracks and excessive wear or pitting. Thoroughly clean gasket surfaces and align- ment fits in order to remove rust and debris. Repair or replace the casing if you notice any of these conditions: • Localized wear or grooving that is greater than 3.2 mm | 1/8 in.

5.4 Reassembly Install the O-ring (412F) around the liner lip and install suction cover with cap screws (370E) and washers (528K). Check for free rotation by turning impeller clockwise by hand with wrench on im- peller screw. 12. When connecting electrical service, make sure polarity is correct to give counterclockwise rotation when looking into the suction opening.
