How do you remove the impeller to replace the seal?

please follow this steps . God bless you

1. Turn off the pump motor and close the input and output valves.
2. Loosen the fasteners that secure the tube connecting the pump and motor.
3. Move the motor away from the pump housing.
4. Remove fasteners holding the diffuser to the backplate.
5. Inspect the diffuser and O-ring for wear, replacing as needed.
6. As needed, remove fasteners attaching the impeller to the shaft. Alternately, the impeller may be screwed on to the end of the shaft.
7. Remove the impeller and seal from the shaft.
8. Inspect and replace the impeller and seal.
9. Reassemble the pump.

please make this steps and fix it. God bless you
Replace a pump seal:

1. Turn off the pump motor and close the input and output valves.
2. Loosen the fasteners that secure the tube connecting the pump and motor.
3. Move the motor away from the pump housing.
4. Remove fasteners holding the diffuser to the backplate.
5. Inspect the diffuser and O-ring for wear, replacing as needed.
6. As needed, remove fasteners attaching the impeller to the shaft. Alternately, the impeller may be screwed on to the end of the shaft.
7. Remove the impeller and seal from the shaft.
8. Inspect and replace the impeller and seal.
9. Reassemble the 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 v-clamp from wet end.
Remove diffuser from wet-end using a flat blade screwdriver.
Remove impeller screw by turning clock-wise(this is a reverse threaded screw (some impellers dont have an impeller screw))
Remove back end of motor using a 1/4" hex driver.
Secure rear end of motor shaft by slipping a 7/16" open face wrench into rear electrical compartment
While securing the shaft, turn the impeller counter clockwise until its off.
Remove seal halfs and replace with identical seal.
Reverse to finish the install

The shaft seal more likely than not needs to be replaced. If your shaft seal has been leaking for any length of time, the bearings could be damaged and this should be replaced. The whisperflow uses a PS1000 shaft seal and is fairly easy to replace (most seals available online or at most swimming pool retail stores). It is best advised not to run the pump until you have had this inspected by a licensed pool technician or have changed out the seal.

1) Make sure breaker/power to pump is off. 2) Remove the six bolts holding the wet end to the seal plate. 3) Remove the diffuser to expose the impeller. 4) Remove the screw in the middle of the impeller by turning clockwise (left hand threads). 5) Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. 6) Once the impeller is off, remove the four bolts holding the seal plate to the motor. 7) Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. 8) Apply a thin coat of lube (I prefer Magic Lube or Lube Tube) to the seal plate and impeller where the new seal will go. 9) Remove the new PS1000 shaft seal from the box (being careful *NOT* to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. 10) You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. 11) Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. 12) Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.
Check the pump for operation and you should be good to go!

Turn off the electric first. Now split the pump in two by removing the large clamp or 4-6 bolts holding the two halves together. (not the 4 bolts holding the motor to seal plate, but the the bolts holding the seal plate to the seal plate housing). Once you remove the clamp or bolts, the motor with seal plate, diffuser, and Impeller can all be pulled back away from the pump. Then disconnect the electrical from the motor and you can pull the motor with the seal plate, and impeller all the way out and work on it. To get to the impeller, you need to remove the diffuser (plastic housing that goes around the impeller) usually by a series of 3 to 6 small screws. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under the thermal overload switch, or removing the capacitor for even easier access. Once you've locked the shaft, you can just unscrew impeller. If the impeller has a bolt or screw in the middle remove that first. this screw will be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure to replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white ceramic, and black graphite surfaces 100% free of any dirt, grease, etc while working with them. Installation is pretty much just the reverse. Install half the seal into the seal plate. Install the seal plate onto motor and bolt into place. Install other half of seal onto shaft. Screw impeller onto shaft and install screw (if one was there to start with) in center of impeller (reverse thread). install diffuser over impeller make sure it is centered and doesn't rub the impeller hub. Install new diffuser and valute o-rings. Hookup wiring before re-attaching to rest of pump. Clamp or bolt back together. Pour plenty of water into pot to prime and flip the motor on for a sec or two. Pour some more water. Install pot lid. You should be good to go. Keep in mind there are many different pumps and some variations to the above instructions, but the above should cover most situations. Hope this helps. If you need further assistance post a reply in the comments, and don't hesitate to leave a good thumb rating if you found this helpful. Thanks, and good Luck!

Sounds like maybe your motor bearing are going bad, or have already seized up. When you say "rubber seal" are you referring to the rubber portion of the shaft seal? Either way, to remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. If the bearings are seized up then you'll have to replace the motor, or have it rebuilt.

You are trying to remove the pump so you can replace the impeller correct?
To remove the impeller you do not need to remove the whole pump. Turn off the electric first. Then just remove the several bolts and separate the back half from the front. Then disconnect the electrical from the motor and your can pull the motor with the seal plate, and impeller all the way out and work on it. To remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread).

After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. Make sure replace the shaft seal, and use a tiny bit of pool lube on the rubber parts when installing, but keep the white and black ceramic surfaces 100% free of any dirt, grease, etc while working with them

Replacing a shaft seal requires some good mechanical ability.
first, always make sure power is off at the breaker before you work.
You'll have to remove the band holding the wet end to the seal plate. Then remove the diffuser covering the impeller. Remove the cover on the back of the motor. You either need a 7/16 open end wrench or a armature tool to hold the motor shaft while you unthread the impeller (if the impeller has a screw in the middle, you will have to remove it by turning clockwise, left hand threads) counterclockwise. You can then pull the carbon part of the seal off of the impeller, make sure to remove all of it including the metal sleeve. You will then have to remove the seal plate and push the ceramic part out from the back. You can then clean and lube the seal plate and install the new ceramic part of the seal, try not to touch the ceramic with your hands if possible. You can then lightly lube the impeller shaft and slide the carbon part of the seal with the carbon facing toward the ceramic as you thread it on. If the seal plate had a copper heat sink, you can either replace it or use a different size seal. (I believe it's a PS-201) Re-install the seal plate, impeller (and screw if applicable) and diffuser. You should now be ready to mate the seal plate to the wet end. Make sure you fill the pump before you try starting it up, especially with a new (dry) seal.

Make sure breaker/power to pump is off. Remove the six bolts holding the wet end to the seal plate. Remove the diffuser to expose the impeller. Remove the screw in the middle of the impeller by turning clockwise (left hand threads). Remove the dust cap at the rear of the motor and use a wrench to hold the shaft while you remove the impeller by turning counterclockwise. Once the impeller is off, remove the four bolts holding the seal plate to the motor. Press the old seal out of the seal plate and clean it thoroughly. Remove the ceramic part of the seal from the impeller and clean it thoroughly as well. Apply a thin coat of lube to the seal plate and impeller where the new seal will go. Remove the new PS1000 shaft seal from the box (being careful not to touch the ceramic or carbon face with your fingers), press the metal part into the seal plate carefully, try not to bend the metal and make sure its completely seated against the seal plate. You can now install the seal plate back onto the motor and secure with four bolts. Press the ceramic part into the impeller, use cardboard or paper between your fingers and the ceramic face. Once you have seated the seal into the impeller, hold the motor shaft and thread the impeller on until snug, then reinstall the stainless screw, remember it is left hand thread so you'll have to turn it counterclockwise. Reinstall the diffuser over the impeller and then install the wet end onto the seal plate using the six bolts, don't overtighten them.

It is a good idea to replace the tank o-ring when taking to pump apart, but if the o-rings are in good condition, just apply a light coat of lube and reuse them.

This is a general guide for replacing a seal, if you have trouble removing the impeller, you may need an impeller wrench and a tool to hold the motor shaft.
