Question about Jacuzzi 34 Hp Lrc Swimming Pool Pump

I have a Jacuzzi LR pool pump that only humms and does not pump. The Impeller is moving freely but with some resistance - I think. I don't know where to go from here.

I have the 7-184948-22 1 hp Got home to day (very hot ) motor was triped off. Reset and now it just hums, locked up. Any hope? It's about 3 years old

Turn off the power at the breaker, then reach in to the impeller and see if it will turn freely. If it does you probably only need to replace the capacitor. If it will not turn freely you'll have to remove the motor end by unscrewing the large ring that holds the motor to the wet end. Remove the small screws that hold the diffuser cover and inspect the impeller and impeller ring, sometimes known as an impeller weir or floating eye seal.
Even if you have to replace the motor this pump is worth saving if there is no damage to other components. Note: Replacement motors are easy to find, I favor Magnatek / A. O. Smith motors but any brand such as Emerson or other will do. Jacuzzi parts though are getting increasingly hard to come about.

I have an above ground pool with a jacuzzi pump. (1.5 hp). I just replaced the sand in the sand filter. I also put on a new o-ring on the jacuzzi pump cover. When I turn on the filter, the pump fills up...

I think you have a air leak. A 1.5 hp motor is very strong and should vacuum well. Be careful to not over tighten the top of your pump housing.

Is your impeller in good shape? It may be worth your while to remove the pump motor from the pump. While you have it apart, replace all the seals (there is a kit for this). Inspect the impeller and all parts of the housing - any junk inside? Remove it. After you complete the rebuild, reinstall the motor, fill the pump housing with water, secure the top and start the pump.

Let me know what happens ...

I think you have spun the center out of the impeller. Get a replacement impeller at your pull supply place.

How do you get the impella of a jacuzzi lr swimming pool pump

looking at he face of the impeller turn counter clockwise, with a large set of CHANNELLOCK 20" Pliers Channel Lock Model 480 cost about $70.00 there is a notch on the back of the motor shaft for ether a 1/2 or 7/16 open end wrench to fit in to hold the rotor from turning. warning ! these pumps are hard to find parts for so you want to have the right tool so you don't break anything. your best bet is to bring it to your local pool pump motor repair guy and have him do it, if its just the seal you are trying to replace it should be a $20 job
if'n i was any help vote ... thanks ..jay .. and prime the pump after a repair !

Motor turns on then off.impeller turns freely?

More info needed ... the impeller should turn freely when in the off position, both directions. If it is running backward when it is off, there is air in your filter causing back pressure. OR, (let me ask) is there another pump on this circuit? Fix your air leaks. Be careful when starting the pump ... if the air pressure is running the pump backward when you turn it on, you will DEFINITELY spin the center out of the impeller.

It could be that you spun the center out of the impeller if you are not pumping when the power is on.

Have you disassembled the device yet?

Tell me more.

We are having issues getting the impeller apart on the jacuzzi magnum force pool pump and need some instructions on how to proceed.

I believe the jacuzzi pump impeller has a locking screw directly in the middle of the impeller. You'll have to turn it clockwise to remove it. Then you'll need to remove the cover from the back of the motor using a 1/4" nut driver. Depending on the motor, you should be able to use a 7/16" open end wrench to hold the motor shaft from turning as you turn the impeller counter-clockwise to remove it. Some motors are different, some have a keyed shaft or require a special tool to hold the shaft while the impeller is removed. Hope this helps.

Jacuzzi pump not pumping

I would probably say that the pump is clogged up or frozen. The motor humms until the heat sensor clicks it off. Try taking apart the front of pump and see if it turns and you should see the problem. Parts are available at most pool stores. Pumps are usually cheaper online.

Motor just humms.

It is not the impeller that is at fault here but the motore itself. If you feel up to the job, buy a replacement motor with an installation diagram and install it. Make SURE the power is cut off at the circuit panel.

Jacuzzi magnum pool pump impeller broke

The impeller on the Magnum pump unthreads counter clockwise as do other impellers. There is a shaft of the motor that runs the length of the motor, on the back of the motor when you take the bell housing off you will see a small silver spot with a **** in it for a standard screwdriver. Put the biggest one in there you can and then grab the impeller and turn it counter clock wise and it should unthread. Sometimes they won't if it has been on there a number of years. You will need to break it off if it doesn't unthread. Then just purchase a new Impeller for the Jacuzzi Magnum Pump.
