How do you remove the impeller on a mission magnum centrifugal pump?


Open up the pump housing, by separating it into 2. Reveal the impeller. If there is a center screw in the middle of the opening of the impeller, it will normally be backwards threads. Remove that.
know if the impeller should unscrew off of the motors shaft, that will be normal threads. But, to do that, you will have to lock the shaft from spinning. Remove opposite side Cap on the motor, to reveal the shaft. Either use a wrench or flat blade screwdriver to lock the shaft. Now unthread the impeller from the motors shaft.

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

Impeller


J5s is a back pull out. Remove the bolts holding the front casing to the motor. Remove the diffuser. The impeller will either be screwed on. ie the impeller is moulded with a thread, or key wayed .ie a separate metal nut holds down the Noryl impeller and a small piece of "key" steel keeps the impeller on the shaft.
Remove the rear fan cover, and either use a flat screw driver (if there is a slot in the rear of the shaft) or a shifter (if the shaft has a hex) or you may have to prise the fan off. to get a good hold of the shaft.
Hold the rear of the shaft, and with the correct socket undo the hex on the impeller. either the nut or the whole impeller will come off. If just the nut type. Use cable ties to thread down the centre of the impeller to the out side and join. do this in a couple of places.Use these as a lever point to pull off the impeller.
The seal just pulls off. there is two parts stationary and rotating.( 18th may, yourve probably worked it out by now)

How do I remove impellor from a/o smith 7-181327-03 pool pump


If the impeller is fused onto the shaft by rust or mineral build up the chance you will be able to remove it with out destroying it are slim. You're likely going to need a new impeller and shaft seal kit, so I'd suggest getting them before your try to remove the old impeller.
First you must remove the water/plumbing and the strainer basket assembly or pump faceplate if applicable to gain access to the impeller.
Step two, on the backside of the motor (opposite side of impeller) you will find the back end of the motor shaft. This end of the motor shaft has a slot in it so that you can insert a large flat screw driver. This will help you to hold the shaft while you try and unscrew the impeller. fyi your pump might have a plastic housing on the back of the motor which you should remove to get to the back of the shaft. This is best way to remove the impeller but its likely to be a struggle if there is rust on the shaft. Good Luck

I have a Pentair 2.0 pump that I am trying to remove from the impellar. The shaft turns allowing me to turn the pump part itself but I can not pull it loose from the rest of the housing. How exactly do I...


The impeller is threaded onto the motor shaft. On 2hp motors and above, there is usually a screw with reverse threads to help secure impeller to shaft. To remove impeller, first remove screw(reverse threads) Next, remove back cover off motor. The shaft either has a slot for a screwdriver or flats for a wrench. Hold shaft and unscrew impeller.

How to remove impeller from motor to replace. I 've removed all the bolts but can't remove the impeller from the shaft.


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.

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.
