D-Series Pump End Kits

Assembly Instructions

1/3 to 3 HP 56C Frame

1. Make sure all the components of the kit are clean, free of burrs and t

properly during the assembly process.

2. If applicable, remove the protective lm from the motor shaft. Make

sure that each motor has the slinger properly installed. This slinger is

very important and it prevents water from entering the motor along the

shaft.

3. Apply anti-seize on the inside of the shaft coupling and install it on the

motor shaft. Make sure that the set screws are in line with the keyway

and that their tips rest at on the bottom of the keyway. Do not tighten

the set screws.

4. Position the pump bracket with the nameplate area on the top. Install

the bracket with four bolts.

Do not misalign or bind the bracket when you are tighten-

ing the bolts.

Tighten the bolts in a diagonal pattern to the following torque speci-

cations:

• 3/8” bolts to 20 ft-lb,

• 1/2” bolts to 45 ft-lb

• 5/8” bolts to 93 ft-lb

5. Adjust the distance between the shoulder of the shaft coupling and

the bottom of the mechanical seal pocket according to the table below

the drawing. The adjusting distance (X in the drawing and table) in-

sures that the spring of the mechanical seal has the proper tension.

6. Tighten the set screws at the shaft coupling to a torque of 108 in-lb.

7. Apply P80 lubricant emulsion or an equivalent on the mechanical seal

o-ring cup and install it into the bracket. It is very important to keep

the sealing surfaces as clean as possible. Therefore, avoid touching

them and keep them clear from residue and debris.

8. Apply P80 lubricant emulsion or an equivalent on the mechanical seal

bellows and spring and install them on the motor shaft coupling. Again, the sealing surfaces should be kept as clean as

possible. Therefore, avoid touching them and keep them clear from residue and debris.

9. Install the impeller on the shaft coupling. Use 242 Locktite or an equivalent locking compound on the threads. Make sure

the impeller hub is tight against the shoulder of the shaft coupling. Make sure the spring retainer at the mechanical seal is

in the proper position against the hub of the impeller.

10. If it is supplied, install the jam nut on the shaft coupling and tighten it against the impeller. Use 242 Loctite or an equivalent

locking compound. Tighten the jam nut to a torque of 45 ft-lb.

11. Apply P80 lubricant emulsion or an equivalent on the large o-ring and then install it on the outside diameter of the bracket.

12. Carefully place the volute into position. With the discharge pointing in the desired position, install the required quantity of

bolts.

Tighten the bolts in a diagonal pattern to the following torque specications:

• 3/8” bolts to 20 ft-lb,

• 1/2” bolts to 45 ft-lb

Do not misalign the volute when you are tightening the bolts. Align it carefully and take care not to pinch the

o-ring.

13. Rotate the impeller by hand and make sure that it rotates freely. Tightness of the impeller implies a bind or a misalignment.

5 to 50 HP JM Frame

1. Make sure all the components of the kit are clean, free of

burrs and t properly during the assembly process.

2. If applicable, remove the protective lm from the motor

shaft. Make sure that each motor has the slinger prop-

erly installed. On 50 HP (230/460 V) motors, remove the

metal slinger and replace it with the slinger from the kit.

This slinger is very important and it prevents water from

entering the motor along the shaft.

3. Install the small square ring on the motor shaft. Apply

P80 lubricant emulsion or an equivalent on the small

o-ring and then slide it up against the square ring.

4. Apply anti-seize on the inside of the shaft sleeve and

then slide it over the motor shaft with the stepped end

against the motor shaft shoulder. The sleeve must slip

over the lubricated rings and sit rmly against the motor

shaft shoulder.

5. For DC4 models only: Install the compression hose

connector in the bracket using a Teon sealant or an

equivalent.

6. Apply P80 lubricant emulsion or an equivalent on the

mechanical seal o-ring cup and install it into the bracket.

It is very important to keep the sealing surfaces as clean

as possible. Therefore, avoid touching them and keep

them clear from residue and debris.

7. Position the pump bracket with the nameplate area on

the top. Install the bracket with four bolts.

Do not misalign or bind the bracket when you

are tightening the bolts.

Tighten the bolts in a diagonal pattern to the following

torque specications:

• 3/8” bolts to 20 ft-lb,

• 1/2” bolts to 45 ft-lb

• 5/8” bolts to 93 ft-lb

8. Apply P80 lubricant emulsion or an equivalent on the

mechanical seal bellows and spring and install them

on the motor shaft sleeve. Again, the sealing surfaces

should be kept as clean as possible. Therefore, avoid

touching them and keep them clear from residue and

debris.

9. For DC4 models only: Lubricate the inside of the brack-

et (hub) wear ring with petroleum jelly or an equivalent.

10. Place the square key into the shaft keyway and carefully

slide the impeller over the motor shaft.

For DC4 models only: Make sure the spring retainer at

the mechanical seal is in the proper position against the

hub of the impeller.

For all the other models: Discard the spring retainer at

the mechanical seal.

11. Push the impeller towards the bracket until it contacts the

shaft sleeve. Install the impeller washer and the impeller

bolt at the shaft end. Use 271 Loctite or an equivalent

locking compound. Tighten the bolt to the following

torque specications:

• 3/8” bolts to 21 ft-lb,

• 1/2” bolts to 90 ft-lb

12. Apply P80 lubricant emulsion or an equivalent on the

large o-ring and then install it on the outside diameter of

the bracket.

13. For DC4 models only: Install the compression hose

connector in the volute using a Teon sealant or an

equivalent.

14. For DC3 and DC4 models only: Lubricate the inside of

the volute wear ring with petroleum jelly or an equivalent.

15. Carefully place the volute into position. With the dis-

charge pointing in the desired position, install the re-

quired quantity of bolts.

Tighten the bolts in a diagonal pattern to the following

torque specications:

• 3/8” bolts to 20 ft-lb,

• 1/2” bolts to 45 ft-lb

Do not misalign the volute when you are

tightening the bolts. Align it carefully and take

care not to pinch the o-ring.

16. Rotate the impeller by hand and make sure that it rotates

freely. Tightness of the impeller implies a bind or a mis-

alignment.

17. For DC4 models only: Install the polypropylene tubing

into the compression hose connectors.
