Our centurion pool pump motor Model B128 replaced less than 1 year ago. Pool company has to replace the impeller twice. Is this common? I believe the pool co sold and installed a used pump instead


Broken impellers generally are not caused by the pump's motor. Impellers usually fail due to back pressure from the filter when the pump shuts off. Air in the filter is compressed while the motor runs, on your pump 12-15 psi. or a bit higher.

When the motor shuts off that compressed air forces water back to the pump, sometimes with enough force to loosen (or completely throw off) the impeller. If the impeller is loose when the pump starts up again it will instantly re-thread the impeller and strip out the threads.

Check to see if you have a suction leak. After the pump has turned on, bleed the air out from the air relief valve on top of the filter. After the pump has run for a while open the air relief valve and see if air comes out. There should be no air, or just a little.

I have seen this back pressure strong enough to blow the skimmer basket up onto the deck.

What make and model of pump and filter do you have?

How to change the seals on a jacuzzi magnun force 1 hp pool pump


Hi,
If you haven't already figured out how to change the seals on your Jacuzzi Magnum Force pump, I can help by supplying a diagram.
Here is the parts explosion for that pump.
Start by removing the case/basket assembly, then the diffuser to get to the impeller. Loosen the impeller to get to the seal plate.
When going to the trouble of changing the shaft seals one should change all the hosing seals at the same time because its a lot of work.

I have a arien snow blower (924 series) that does not blow snow out the impeller. the auger just pushes it. bothe the impeller and the auger turn. the shear pins for the auger are in. the rear key...


Run the impeller without any snow coming into it--hold your hand over the exhaust of the impeller to check for considerable wind force. If almost non existent, make sure the impeller is being driven at full speed. Is there a shear pin related to the impeller? The only other problem would be if the impeller was running the wrong direction, but I don't see how that would be possible. Hold the impeller with your hand while trying to turn the pulley--there should be no slipping between the two. Hope this helps!

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.

Our Jaccuzzi Magnum Force pump extremely low pressure


Giving it a good cleaning probably clogged the pump impeller. If you vac'd the pool and the pump basket was packed with debrie it probably passed through and clogged. Split the pump and inspect the eye of the impeller. Low pressure means low flow.

I disassembled the pump but I can't get the impeller off. It's stripped and needs replacing. I don't want to force it and break something else. What is the best way to remove the impeller? It's the No


I broke the outer circle of the impeller off with a screw driver and then used a Dremel tool to cut the plastic down to the shaft so I could break if off the threaded shaft.

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.
