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

How do I removie the impeller to renew the seals the pump ie leaking and I have new carbon seals nad I have removed left hand ihread nut at the front of the impeller but it will not come off


Thank you for posting your question here on Fixya.com.


Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.


Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.

Winding noise with some water leaking from the motor seal. Water still flowing but sounds laborous.


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!

I am trying to remove the impeller on a SP158015, to change the leaking seal to the motor shaft. Is the impeller threaded?


The instruction below may vary slightly for your model pump, but should give you the info you need to get the impeller off and get to the seal... 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 the thermal overload switch 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. 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!

How do you remove the empellor from the motor shaft? The seal is leaking. I have the 4 screws loose holding the pump casing. Does is slip off the motor shaft or is it threaded on?


First off, are you sure it's the shaft seal leaking and not the Valute (the large o-ring or seal that is in between to two halves of the pump) seal? To clarify, if you get your head down and look at the bottom of the pump while it's running you should be able to see the water coming from the joint between the seal plate, and the seal plate housing, or just behind that from the bottom of the motor probably from the vent holes in the motor housing.

Now to answer your question, assuming it is the shaft seal leaking.... You may have already done some of these steps, if so, sorry - just ignore, but it may help others. To get to the impeller, you need to split the pump into two (the wet end from the dry end) This is done by either removing a large clamp, or removing 4 to 6 bolts depending on the pump. (I'm not talking about the 4 bolts that hold the motor to the seal plate, those come later see below) Once you do this the Motor, seal plate, impeller and diffuser will all pull back away from the front of the pump. At this point it's best to disconnect the electric and remove the whole assembly so you can work on a table or bench. Before removing the impeller you need to remove the diffuser which is screwed over the impeller onto the seal plate with 3-6 small screws. To remove the impeller you need to lock the motor and just 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 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. One thing to note and/or clarify... in your description you said you have the "4" screws loose... As I mentioned above, most pumps have either a large clamp or 6 bolts holding the two halves of the pump together. In your case I believe it's bolts. Some have 4, but most have 6. Then there also 4 bolts that hold the motor to the seal plate. Just want to clarify that you split the pump in two and remove the diffuser, and impeller, before removing the motor from the seal plate. I haven't worked on a Waterway in awhile, but there are basically the same as many other pumps. You may have 4 bolts, just wanted to clarify from the motor mounting bolts. If something looks different on your pump from my description let me know by leaving a comment and I'll clarify asap. Good Luck!

Water pump doesn't work but there is no water leak it can be just a sensor problem?


No, but it could be the impeller inside the water pump, has come loose from the impeller shaft.

A leaking seal indicates that the bearing, or bearings, for the impeller shaft are bad.

I have replaced water pumps, (With a brand new one), and have had to remove it, and reinstall with another one.
Why?
Impeller is spinning around on the impeller shaft. The machining done was a bad job, and the impeller wasn't staked to the impeller shaft.

2003 yz impeller seal is leaking, do i need to replaice head gaskets thanks ian


I am not sure what you mean by impeller seal so here are a few scenarios:

**Note: Based on YZ250. others may be similar.

-If the gasket around the impeller housing is leaking you can replace that on its own. Open rad cap, drain the coolant using the lower screw with the copper washer behind it. Then remove the other 3 bolts, remove cover, clean mating surface, install new gasket, snug everything up, and replace the coolant.

You don't need to replace the head gaskets unless your leaking from there, or getting coolant in the engine.

The same would apply to your base gasket.

just in case:

-if your transmission/gear oil is milky, your will have to change the oil seals on the impeller shaft.
