INSTRUCTIONS FOR ASSEMBLY

1. Insert shaft into the coupling with the key in the keyway. Ensure shaft is seated completely into the coupling.

2. Your support table set up may vary, but we recommend having access below the table to secure shaft to build fixture (step 4).

3. Install the motor bracket to the build fixture by aligning bracket holes with four hubs on fixture. Install the shaft onto the fixture ensuring the coupling is completely seated on the shaft stub.

4. Insert assembly fixture bolt from bottom of fixture and screw into coupling with Allen wrench until tight.

5. Once the bracket and shaft are installed, insert the lower impeller (with large collet nut) onto the shaft.

6. Tighten the nut to the torque shown in table 1.0.

7. Only on the first impeller, place the graphite disc on all models with the exception of 360SSI in the SSI 6" Series and models of the 10" SSI Series.

8. Slide diffuser over the impeller and upthrust washer until it is seated completely down on the motor bracket.

9. Repeat the steps to place the next diffusers, inserting the impellers (A) first, and then adjusting as indicated using a torque wrench and the torque chart indicated for each pump (B). When sliding the different diffusers to cover the impeller (C) and thereafter, we recommend checking your alignment with respect to the welding point in the diffusers for a better final appearance (D). Do this until you reach the discharge assembly.

10. Install the upper diffuser (does not contain wear ring) and the discharge. Make sure to align the strap locations on the discharge with the holes in the motor bracket. Depending on the size of pump, the slot may have a different configuration and location on the discharge.

11. Apply anti-seize (White Knight) to the threaded studs on each strap. Insert strap into slot. Ensure strap is completely seated into the slot. Slide threaded stud into motor bracket mounting hole. Ensure the stud extends through the hole.

12. To ensure straps are completely seated, use a rubber hammer to tap them down.

13. Repeat Steps 11 and 12 for each strap.

14. Slide washer onto the stud and thread nut. Repeat for other straps. Torque per Table 2.0. Recommend tightening in a crisscross pattern to maintain even torque on all sides. For 10” models, place Strap Blocks on motor bracket to prevent strap twisting during installation and tightening process. NOTE: The stainless steel strap nuts have been anodized to prevent galling.

15. Remove the pump from the build fixture by removing the fixture bolt from underneath the fixture and lifting off the shaft stub. Lay the pump horizontal on workbench or horizontal support. CAUTION: On pumps with higher stage counts, support center of pump when laying it horizontal to prevent the pump from bowing.

16. Check that the pump shaft spins freely by inserting the appropriate Motor Shaft tool into the coupling and rotating.

17. Check that the shaft height is within the defined range. See Table 3.0 for dimensions. Measure with a shaft height gauge.

INSTRUCTIONS FOR ASSEMBLY

18. Apply Loctite® 302-43 to the set screw from the motor coupling kit and reinstall the screw on the shaft coupling. Use 5 mm Allen wrench to tighten.

19. Once secured, identify the cable guard included with the corresponding pump model.

20. Cable Guard Assembly: For 6” pumps continue to Step 21. For 8” pumps, go to Step 34.

21. Orient the cable guard so the angled tab is on the motor bracket end and the top two tabs extend past the pump’s discharge.

22. Install the cable guard tabs closest to the motor bracket.

23. Gently tap the side of the cable guard to drive one of the tabs under the strap.

• Do not tap the tabs.

INSTRUCTIONS FOR ASSEMBLY

24. Use the small flat-head screwdriver to gently raise the strap on the opposite side of the cable guard.

25. Gently tap the other tab under the strap. Remove the screwdriver after the cable guard tab has started under the strap.

26. The cable guard should be centered between the two straps.

27. Repeat steps 23–26 for all the tabs except the top two.

28. After all but the top two tabs have been installed, gently tap the top end of the cable guard down toward the motor bracket.

• Be careful not to damage or bend the cable guard.

29. Apply pressure to the end of the cable guard while tapping on the top side of the tabs close to the motor bracket. This will allow for the end of the cable guard to slide under the motor bracket ears.

30. Gently tap the cable guard to drive one of the top two cable guard tabs under the strap.

31. Use the small flat-head screwdriver to gently guide the tab under the strap on the opposite side of the cable guard.

32. Once the tab is started under the strap, remove the screwdriver.

33. The cable guard should be centered between the two straps.

34. For 8” and 10” pumps, remove the cable nuts from the Discharge and Motor Bracket.

35. Place cable guard on studs., Install nuts and tighten.
