Impeller tightens on Aqua-Flo Series A brass pool pump
I installed new seals on an Aqua-Flo Series A brass pump (seal part no. PS-1000 per many cross-references and my pool store) and only hand-tightened impeller back on to the shaft, but when motor turned on it screwed the impeller onto pump bracket so tight it could not turn. Is there another part like a spacer that I may have lost on disassembly or is the seal the wrong part? I kept the old seal and it looks the same but have not removed the new one for an exact comparison because that would likely ruin the new one. I can't find any documetation on the clearance between the back of the impeller and the bracket should The pool store is closed today and I need to get the pump running ASAP.

Re: Impeller tightens on Aqua-Flo Series A brass pool...
Thank you for posting your question here on Fixya.com. There is no spacer. The impeller's internal nut and the shaft's shoulder set the spacing. The most likely problem is either the spring portion of the seal is not fully seated into the pump housing or the ceramic portion not fully seated into the impeller. You should also be sure you removed ALL of the old seal and parts. Many people leave the ceramic's boot in place and then the new seal seat will not seal properly.

The two most common causes for leaking pumps are worn out seals or leaky gaskets. The seal can be replaced and the pump can last for a long. The same thing can be said for a leaking gasket. I don't know what parts are available but many pumps can be assembled after buying all the parts. It is just higher priced.
If you are mechanically inclined you can do either of the above jobs but it best to watch someone else do it first. If you bring your pump to Leslies pool supply when they are not very very busy they can usually repair it while you watch.
you will need to remove the back cover on the motor and the suction side cover to expose the impeller. You'll need to hold the shaft from turning and remove the impeller by turning counterclockwise. Some impellers will have a phillips head screw in the center, if so, you can remove it by turning it clockwise. Once the impeller is removed, you can loosen the through bolts and it will all come apart. You can install the new seal and reverse the process to put back together. Hope this helps.
If you had any blow back when the power went off then the impeller might have spun off the shaft of the motor. If you take it apart the impeller should be almost touching the pump seal plate. It should also be even against it. If it is uneven or has a space behind it you might have to replace it. Also you can check the "O" rings inside the pump to see if your bleeding pressure back to the suction on the pump. I hope this helps.
Thank you for posting your question here on Fixya.com. The rotating assembly, with the spring, goes on the back of the impeller with the shiny carbon face away from the impeller. That face mates to the white ceramic face of the stationary portion. The rubber (black) boot seals the white ceramic into the pump housing. The cardboard 'ring' is provided to allow you to press in the stationary portion without touching it. You DO NOT want to touch either seal face (The shiny parts that rub against each other once you are done). Doing so can cause a brand new seal to leak.

You will need to get access to the impeller, then unscrew it counter clockwise. You will have to hold the shaft of the motor to unscrew the impeller. You can gain access to the shaft by popping off a little round cover on the back of the motor, you should see a slot in the motor shaft. Once you get the impeller off, unscrew the thru-bolts. The housing should pull right off. From there you can pop out the seal half that is in the housing and replace it - the other half of the seal is on the impeller. These 2 pieces come with the new seal. When you put the housing seal half back in use some silicone around it. The impeller end just pushes on. Link to Aqua Flo XP2 Diagram
Pump seal is in two pieces. The piece with the spring should be easy to remove. To remove the piece that is inside the motor side of the pump housing, place the housing with the side that should be facing the motor downdwards on a flat surface. The hole in the housing is larger than the seal, so use a screwdriver and, placing first on one side of the seal and then the other, strive the handle of the screwdriver sharply and the seal should pop out the bottom. The seal is rubber, with a ceramic insert, so if you don't tap the screwdriver too sharply the insert won't be damaged. In any case, it's a good idea to replace the entire seal if you have had to open the pump and remove the impeller
The impeller is threaded on to the shaft. The trick is to hold the shaft in order to untread the impeller. The surest method is to disassemble the back of the motor, exposing the opposite end of the shaft. There should be a spot to put a wrench in order to hold the shaft immobile. Then, it's simply a matter of unthreading the shaft. A strap wrench does a great job of holding the impeller without damaging it.
