This pump is designed to accept an o-ring on the discharge  

 

flange and inlet chamfer as a backup to the NPT or BSP  

 

threads to ensure leak-free operation after temperature  

 cycling.

  

After verifying the setting and setscrews tension on the  

 

 

drive magnet assembly, grip the pump end by the dis- 

 

charge and the opposing front edge of the motor adapter    

 

and install the pump end on to the motor.  Secure to the  

 

 

motor with correct hardware (items 10A, 10B, and 10C).

 

CAUTION

:  Do not allow fingers between the motor face  

 

 

and the motor adapter.  

2.  For metric pumps - Follow assembly instructions for metric  
 

pumps on page 1, steps 3 through 10.

 

Note:

  Plastic pumps will expand and contract with tem- 

 

 

perature, so periodically check and hand tighten screws.    

BUSHING REPLACEMENT

1.  To remove the bushing, insert a 1/16” pin punch into bal-   
 

ance hole (inner circle of 4 holes) of impeller assembly  

 

(items 2 & 3).  Gently tap the bushing out of the back of the   

 

impeller assembly. The punch may need to be moved to  

 

a different hole if the bushing is difficult to remove.

2.  To replace the bushing, clean the impeller bore. Insert  

 

 

the new bushing into the back of the impeller assembly  

 

 

by aligning the bushing with the impeller bore.  Press  

 

 

gently until the bushing bottoms out (use a block of wood    

 

and mallet if necessary).

REASSEMBLY

1.  56C pumps - Insert the barrier (item 4) into the motor 

  

 

adapter (item 5).  Align the barrier tabs with the motor  

 

 

adapter bolt holes and press/pop into place.  Install the  

 

 

impeller assembly (items 2 and 3) into the barrier. Lubricate  

 

the housing o-ring (item 7) with a chemically compatible  

 

lubricant and install. Carefully place the impeller housing  

 

(item 1) onto the barrier, lining up the discharge with a set  

 

screw access hole (top) in the motor adapter. Be careful not  

 

to dislodge the o-ring. Install the six bolts and washers  

 

(items 9A, 9B, and 9C) and hand tighten the screws follow- 

 

ing the pattern shown in figure 3.

Drain fitting molded boss.  

Use as a guide for drill ing 

and tapping 1/4” NPT.

OPTIONAL DRAIN INSTALLATION SECTION

1.  Remove the impeller housing from the pump assembly.

2.  Clamp the impeller housing to a drill press table.
3.  Using a 7/16” drill and the molded boss as a guide, drill  
 

completely through the molded boss into the interior of  

 

 

the impeller housing. De-burr the hole on the inside of  

 

 

the  impeller housing. See Figure 6.

 

CAUTION:  

Do not tap too deep or the impeller housing  

 

 

may be damaged.

4.  Using a 1/4” NPT tap, tap the hole in the molded boss to    
 

the appropriate depth.

5.  Install drain plug or valve, being careful not to overtighten.

2.  Check for loose magnets on drive assembly or rubbed  

 

 

areas on impeller or barrier assemblies. Contact your 

 

distributor or FTI Technical Service if a problem is found.

3.  If you did not remove the drive magnet assembly, check  
 

the set screws for tightness before reassembly.
