SEAL ASSEMBLY AND MOTOR REPLACEMENT

ROTARY SEAL ASSEMBLY REPLACEMENT 

CAUTION

 Make certain that the power supply is 

disconnected before attempting to service the unit!  The rotary 

seal assembly must be handled carefully to avoid damaging 

the precision lapped faces of the sealing components.

1.   Disengage pump body (Ref. No. 10) from motor mounting ring 

(Ref. No. 2).

2.   Remove diffuser (Ref. No. 6).
3. To remove the impeller use a 9/16" open end wrench to hold the 

motor shaft.  On Uni-frame motors, remove the rear cover, the 

flat area is located between the governor and rear bearing.  On 

Nema J motors, the shaft flat area is located in the middle of 

the mounting ring.  Uni-frame or Nema J motors are indicated 

by 56U or 56J respectively in the frame "FR" block on the motor 

decal.

4.   The rotary seal (Ref. No. 4) will come loose at this time.  Use a 

screwdriver (or similar instrument) to pry the ceramic seal and 

rubber gasket from the recess of the mounting bracket.

   

CAUTION

 Be careful not to damage the motor shaft 

or recess surface.

5.   Clean the recess and motor shaft thoroughly.
6.   Install the new rotary seal assembly. 

     a.   Insert the ceramic seal and the rubber gasket into the recess.

NOTE:  To help facilitate installation, apply a drop of liquid soap to 

the outside diameter of the rubber gasket.  Make certain that the 

ceramic seal is kept clean and free of dirt and/or oil. 

     b.   Slip the remaining parts of the rotary seal assembly onto the 

motor shaft.

NOTE:  Apply a drop of liquid soap to the inside diameter of the 

rubber drive ring.
7.   Replace the impeller and diffuser removed in Steps 2 & 3.
8.   Reassemble the pump body to the motor and mounting bracket.

MOTOR REPLACEMENT (Figure 5)
1.   Uni-Frame motors can be replaced in the field with any standard 

Nema J jet pump motor by following the instructions below.

CAUTION

 Before attempting to replace the motor, 

make certain that the power supply is disconnected and the 

system pressure is relieved.

2.   Remove pump body (Ref. No. 10), diffuser (Ref. No. 6), impeller 

(Ref. No. 5), and shaft seal (Ref. No. 4) by following steps 1, 2, 3 

& 4 of Rotary Seal Replacement.

3.   Uni-Frame motors (indicated by 56U in the frame “FR” block on 

the motor decal) can be removed as follows: 

     a.   Disassemble pump base (Ref. No. 14) from unit by removing 

two (2) 3/8” hex nuts. 

     b.   Remove four (4) thru bolts from rear of motor and pull away 

shell and stator assembly (discard). 

     c.   Disconnect four (4) self tapping screws that hold the bearing 

housing to the mounting ring.  Discard bearing housing, rotor 

assembly and (2) square headed screws.

4.   Replace motor with standard Nema J jet pump motor by 

positioning motor against the mounting frame and assembling 

with four (4) 3/8” x 3/4” cap screws.  The mounting base is 

connected at the bottom of the mounting frame with two (2) of 

the four (4) 3/8” x 3/4” cap screws.

5.   Follow steps 5, 6, 7 and 8 of Rotor Seal Assembly to reassemble 

the remainder of the pump.  Because damage to the shaft seal is 

most likely to occur in disassembly, a new seal will be necessary.

NOTE:  The pumps and motors require no lubrication.  The ball 

bearings of the motor have been greased at the factory and under 

normal operating conditions should require no further greasing.
