8.   Remove the seal plate.

9.   Pry the rotating shaft seal member (including stainless collar 

and rubber seal) from the impeller (Figure 9).

the seal plate (Figure 9).

11. Remove loose particles from impeller hub and seal plate.

INSTALLING NEW SHAFT SEAL

  Before handling shaft seal parts wipe hands 

clean. Dirt or grease MAY damage the seal.

  Se laver les mains avant de manipuler les 

pièces du joint de l'arbre. La poussière ou la graisse POURRAIT 

endommager le joint.

NOTE:

 Be careful not to scratch the ceramic surface of the seal 

seat and push seat enclosed in rubber into seal cavity on seal 

plate. Use a cardboard washer to protect polished surface 

when pushing against ceramic seat with any object. Be sure to 

remove cardboard washer.

2.   Carefully slip seal plate over shaft. Do not disturb seal position 

in seal plate. The seal plate must be orientated during assembly 

so the two screw holes are on a horizontal line across the 

motor shaft (Figure 10). This placement should be done to 

ensure proper draining and priming.

3.   Place rotating shaft seal member in position on impeller and 

press into place. Take care not to press against polished seal 

surface.

4.   Position impeller on shaft and tighten securely (Figure 11).
5.   Secure diffuser to seal plate using the two cap screws. Be sure 

the arrow on the front of the diffuser is pointing up and the 

screws are orientated on a horizontal line as described in Step 

2.

6.   Carefully position pump housing (volute) gasket over the diffuser 

onto the seal plate. In all shallow well applications care must 

be taken that the o-ring is clean and properly positioned on the 

venturi. Cleaning and positioning makes a good seal inside the 

diffuser when assembled.

7.   Assemble the pump housing (volute) to the motor using the 

four cap screws. Be sure the pump housing (volute) gasket is 

positioned correctly and tighten the screws securely.

NOTE: 

Shaft must rotate freely and rear cover should be secured 

before operation.
