Operating Instructions and Parts Manual

10.  Remove the shaft seal from the impeller, make sure the stainless 

steel sleeve comes off the impeller, all you should see on the back of 
the impeller is the brass colored threaded insert (Figure 13).

11.  Remove the ceramic seat and rubber boot part of the seal from the 

cast iron seal plate (Figure 13).

12.  Remove the square cut gasket from the seal plate.
13.  Reassemble the pump with new parts in reverse order.
14.  Wipe down the seal plate to remove any debris or loose rust. 
15.  Push the ceramic seat of the shaft seal into the seal plate using the 

cardboard ring provided to keep the ceramic face clean. You can 
use a little water or dish soap to lubricate the seal pocket to make 
assembly easier.

16.  Slide the square cut gasket over the flange on the seal plate, make 

sure not to let the gasket twist.

17.  Carefully slip the seal plate over the shaft so as not to disturb seal 

position in the seal plate. The seal plate must be orientated during 
assembly so the two holes are on a horizontal line across the motor 
shaft (Figure 14).

18.  Push the bellows side of the shaft seal over the impeller hub, you 

can use a little water or dish soap to lubricate the impeller hub to 
make assembly easier (Figure 15). Make sure after assembly the 
back carbon and white ceramic surfaces are in contact.

19.  Holding the motor shaft with a flat blade screw driver thread the 

impeller onto the motor shaft, hand tighten. Lubricate the nose of the 
impeller with potable water safe lubricant.

20.  Replace the plastic cap over the motor shaft end.
21.  Reassemble the diffuser, make sure the arrow indicating the top is 

pointed toward the top of the pump, torque the two screws to 30 
±10 inch pounds.

the pump body. Torque the screws to 140 ±40 inch pounds.

23.  Reattach the plumbing connections, reconnect the power and prime 

the pump (See section on priming the pump). After reassembling the 
pump check for leaks. If a leak is detected, repair before using the 
pump.
