How do I remove the Impeller of my aquaflo flomaster pump? I have the pump open, and I loosened the 4 screws at the base of the motor so the volute spins freely, but the impeller isn't detaching. Bruce Phillips

At the end you loosened the motor thru-bolts you should have a cap covering the motor shaft end. Remove it to find the end of the shaft. Depending on the motor brand and age you should have either a flatted surface for a wrench or a slot for a screwdriver to secure the shaft from turning. Turn the impeller off counter-clockwise. Some impellers are so stuck you can not free them holding the shaft end this way. Disassemble the rotor from the pump motor and lock the whole works in a vise to then get a better grip on the impeller. Impellers are often cracked from seal failure so do not be surprised if your impeller breaks up before coming off the shaft.

The replacement part number is the 8 digits you will find molded into the impeller plastic. For a quote on a replacement part(s) please contact us thru www.arrowpools.net.

I used a 2" metal clad hose/pipe coupling (Lowe's) that fit the impella and a 2" piece of PVC pipe. I tightened the ring clamps as tight as I could without breaking. I then put an open end wrench on the motor shaft and a pipe wrench on the clamp covering the pvc. It unscrewed counter clock wise with a little effort. The impella was not damaged.

    Thank you David Bertrand! I used a 2" flexible PVC coupling with a 2" PVC Tee coupler at the other end. Slide something long to give leverage through the T coupler. Extracted the impeller from a 1998 vintage XP2.

    PS. be sure to use the rubber sleeve in the coupling.

I removed the front cover to the impeller. Applied wd40 where the shaft meets the plastic impeller between the motor and impeller assembly. I then secured the shaft from the rear with the help of a second set of hand. I then ran a plastic strap, off an adjustable strap wrench, in the discharge hole to line up with the impeller. I secured that with a pair of vise grips. I then took a set of channel lock pliers and turned the impeller counter clock wise very carefully. Did not damage the impeller because the plastic strap gave me the traction the pliers needed to grip the impeller.

Another possibility was the use of an Impeller Wedge. Typically about $15 online. I did not try this but seemed feasible.

How to replace impeller on guolds j10


What is the make and model of the "pump"?
Gould is a motor manufacturer.
The manufacturer of a pump, will use a third-party vendor like Gould, to provide them a motor for their pump. Gould is Century/Magnetek, which is now AO Smith.

BUT...
remove pump housing/volute covered, and access the impeller. Then on the back of the motor you should be able to access the shaft. Lock up the shaft so it does not spin, and then unthread the impeller. Some pumps, especially two speed pumps, will have a locking screw in the center of the impeller. That screw will be counter threaded or backwards thread. It keeps the impeller from spinning off the shaft during normal operation between high and low speeds.

again if we had more specific information, we would be able to assist you better.

Waterway model # pf-50-2n22c


The wet end of pumps come off this way.

  • Remove the face plate of the pump.
  • Put a large flat-head screw driver on the back of the motor on the shaft going thru the motor.
  • Grasp the impeller (with the screw driver in place on the back of the motor) and unthread the impeller counter clockwise.
  • If it doesn't unthread you will need to bust it off
  • On the back of the motor you will find 4 small bolts 1/4" size that run all the way through the motor and thread into the four fingers of the wet end.
  • Unthread those 4 bolts and you can then remove the volute from the motor.

Replace usq1202 pump


It looks like since you have a square flange motor you have either a Tri-Star, a Maxflo II pump or other model by Hayward.. Either way the process is very similar.
Replace the seal, o-rings and gaskets with new ones. Use a teflon based lubricant on all rubber parts, including the seal, but try not to get any on the ceramic (white ring).
  1. Shut power off at the breaker.
  2. Remove the bolts connecting the motor plate to the pump housing.
  3. Back motor assembly out of pump housing making sure that the diffuser and its gasket also come out.
  4. Disconnect the electrical supply.
  5. Remove the diffuser if still covering the impeller, (there may or may not be screws to remove).
  6. Remove impeller ring (if one).
  7. Holding the impeller firmly remove the impeller screw. This is in the center of the impeller and has a REVERSE THREAD, meaning turn screw clockwise to loosen.
  8. Remove the end cap on the opposite end of the motor and use a 9/16" open end wrench to hold the shaft from turning.
  9. Unscrew the impeller CCW.
  10. IMPORTANT -- Note how both parts of the seal are oriented to assure the new one is installed likewise, then pull off the seal and seal plate, and discard old seal parts. Also note which way is UP on the seal plate relative to the motor.
  11. Reassembly to the new motor is basically reversing the steps above.
NOTES:
The impeller ring (if one) is a ring with a lip around one side. This goes over the center of the installed impeller with the lip facing outward, away from the impeller.



Do not over tighten the bolts! You can damage the pump by doing this. Snug plus about a quarter turn is plenty. In the event you have leaking after startup, open the pump back up and check you housing gasket.

Remove a wet end from a aquaflo xp2 spa pump motor how do I do this


There are 4 bolts that go all the way through the motor and thread into the wet end.
The first place to start it to remove the face plate of the wet end exposing the impeller.
The impeller is threaded onto the shaft of the motor.
Take a big flat head screw driver and put it onto the end of the shaft of the motor and hold it tightly so you can unthread the impeller off the shaft of the motor.
Unthread those four bolts that go all the way through the motor.
You are done at this point.

Jacuzzi pump motor leaks at the seal


This means that your pump seals are bad. They are an inexpensive part to replace luckily, but removing the impeller can be tough. There are a number of different Jacuzzi motor/pumps so be sure to get the right seal kit.

Briefly:
The trick is to stop the shaft from spinning while you loosen the impeller. FYI they don't usually come off easily, the older the pump the harder it is to remove the impeller.
On the rear of the motor there is a slot where you can put a flat screw driver into the back of the shaft to stop it from spinning. Once the impeller is off you can remove the volute (rear housing) and change the seal.
Let me know if you need more help.

How to get impeller off of shaft if it's not unscrewing


At the rear of the motor shaft it will be squared off. if you can get a wrench on this and then use a impeller wrench or water pump pliers you can probally break it free. You need to check in the center of the impeller for a set screw. (not on all model pumps) This will be aleft handed screw so to remove it you will have to turn it clockwise. If need be you can put a screwdriver in a fin of the impeller and give it a sharp hit with a hammer to break it free. Once your done and reassembling the pump be sure to only hand tighten the impeller. Good luck.

REMOVE WET END FROM MOTOR ON FLO-MASTER XP2


You will need to remove the six bolts/nuts on the wet end to expose the impeller. At the rear of the motor, remove the cap covering the shaft and restrain the shaft and spin the impeller off (counter-clockwise). Check to see if there is a screw in the center of the impeller and remove it by turning clockwise (if applicable). Once the impeller is off, you can remove the four through bolts from the rear of the motor using a 5/16 nut driver and the wet end should come right off.
