Lock the end of the shaft opposire the impeller and turn the impeller counter-clockwise as you look at the impeller. Some of them require a little 'convincing' in order to get them to spin.

SOURCE: how to remove impeller from motor to replace

If it's a separate shaft, it requires a puller tool, but first you have to remove a nut that holds the impeller to the shaft. If the shaft is part of the impeller, meaning that it is a one piece fabrication, then there is nothing you can do about it. You haven't even stated where does this impeller come from, a washing machine, a water pump, etc.

SOURCE: How do I remove the Impeller of my aquaflo

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.

Is it possible for a centrifugal pump briefly rotated counterclockwise to unscrew itself and make the impeller detached from the shaft.. can the motor put to blame ..thanks

Yes, it is possible for a centrifugal pump to unscrew itself if it is briefly rotated counterclockwise, which can cause the impeller to become detached from the shaft. However, the motor is not necessarily to blame in this scenario. There could be various reasons for this occurrence such as improper installation, vibration, or a problem with the pump itself, such as an impeller that is not securely attached to the shaft.
In order to prevent this from happening, it is important to follow proper installation and maintenance procedures, as well as to regularly inspect the pump for any signs of wear or damage. If the pump continues to unscrew itself, it may be necessary to have it repaired or replaced.

Can my shaft spin and not my impellor. how can i check

the impeller is usually screw onto the shaft or the shaft has a D (flatspot on one side to lock impeller) so no, the shaft cannot spin without the impeller moving unless the shaft is snapped or impeller is totally stripped (ive never seen either)
if the pump is running but not pushing water, take the wet end off and make sure there is no debris (leaves, worms etc) caught in the impeller fins. you will be amazed at how much that will reduce the performance of a pump

Pentair 011523 pump shaft seal is leaking. How do you remove the impeller and motor?

Separate the plumbing portion of the pump from the seal plate which is attached to the motor. The bolts will be a 9/16 inch hex head, that are visible facing the motor. Remove those bolts. That will then allow you to pull the motor and the seal plate away from the plumbing portion of the pump. Remove the diffuser which is covering the impeller, and then the impeller will need to be unthreaded off of the motors shaft. The motors shaft, will need to be locked. You can do this by removing the Cap on the backside of the motor and you can use whatever tool required to keep the shaft from spinning. Once you are able to lock the shaft, you can read the impeller... Note* some styles will have a screw in the middle of the impeller securing it to the motors shaft? This screw is Backwards thread, not normal thread. If your pump has this screw, need to remove it first, then you will be able to unthread the impeller off of the motors shaft.
once the impeller is removed, you can then remove the two halves of the shaft seal. Very carefully reinsert the new shaft seal into the proper places, just the way they were prior to you removing them.

Reassemble in backwards order as you disassembled everything.
good luck

Pool motor leak

If you are asking how to replace shaft seal?

open & dismantle pump from motor. Some will have thru bolt motors all the way thru the motor, heads of bolts are (4 each) visible & accessible at back of motor. Loosen these & your wet end will be detached from the motor once the impeller is removed. To do this, block and prevent the shaft from spinning - normally there is access to the shaft which is located at center behind a cap at the back of the motor. Then unscrew the impeller from motors shaft.

My Laguna pressure flo 2100 filter has stopped working. Any idea what might be the problem.

Have you tried turning the impeller gently by hand? Sometimes this gets jammed.

If it is running but water still isn't flowing you may have an air leak. You can locate one of these by running a hose along the seams and waiting for the pump to prime.

If the impeller turns easily but still will not spin when power is supplied your motor may be dead. If you feel a vibration or noise when powered up and the impeller still will not spin the magnet on the impeller shaft may have detached from the impeller drive.

Except for the motor all are easy fixes with inexpensive parts that should just drop in.

My Hayward just hums when I turn it on and after a few seconds the breaker pops.

You will need to disassemble the pump and check the impeller. remove any debris and try turning the impeller by hand. If it does not move or is dragging, you will need to overhaul the pump. Possibly a shaft seal leak has damaged the motor bearing(s). Replace the shaft seal and motor bearings. If the motor is badly deteriorated, you might need to replace the motor. Note... the impeller turns counterclockwise to loosen. you may need special tools to grip and hold the motor shaft and the impeller to prevent damage to the impeller. If the impeller is seized on the shaft from rust, you may have to break it to get it off. reassemble with teflon lubricant on the shaft threads when reinstalling the impeller. This will prevent seizure later.

Pump disassembly

I removed the impeller on my DW761UQB. The instructions were molded into the plastic pump housing. This is how I DID MINE: Remove motor mount screws. Remove the chopper screw (screw only goes into impeller, not motor shaft). Remove chopper and rotate/remove strainer. Place socket or wrench on impeller tip and place another wrench on rear of motor's plastic fan. Unscrew fan from impeller shaft ( threads are LEFT handed, turn CW). Once fan is 'backed off' of the impeller, CAREFULLY pry the motor/fan from pump housing (impeller is attached to motor shaft via splines). Don't crack the delicate plastic pump housing. Mine was stuck, but separated with moderate force. Now remove the impeller/seals from the pump housing. This worked for MY above mentioned model, I don't know what other models it applies to. I am not a pro.

Impeller loose on pump motor shaft

The bore in the impeller is spun out. Mix some JB Weld and apply a liberal amount to the bore of the impeller, install it back on the motor shaft and rotate the shaft a 1/2 turn to distribute the weld before cure. Originally the impeller was a press fit. Don't allow food to get sucked into the pump, lock down and damage to the impeller will occur
