The volute on my Polaris pump cracked the other day. Happened to be home when I saw the water spraying everywhere. Replaced and started up my 2.0 HP filter pump. Was having a little issue with getting a solid prime but it’s normally got a few bubbles blowing through my returns. After about 10-15 mins of semi-priming the pump just turned off. I checked the impeller and found no obstructions. I used a drain bladder while it was off to try and clear any other debris. Turned pump back on and it fired up with a not of trouble priming. Turned it back off after 30 seconds and filled the basket with water and tightened the lid. I stuck a drain bladder down a return line in one of my skimmers. Turned pump back on and it fired up. I was able to get a prime after a minute or two. Came back out a few mins later and prime was lost, but then I heard it catch again and it primed but blowing a lot of bubbles. A few mins later the pump cut off again. No visible leaks in my piping. I did notice the basket on the pump housing was whining a lot after it turned off. When I opened the cap the pressure released and it stopped.

The pump is about 6 years old. Is it overheating from not getting a prime or is it time for a new one?
 
If it started with the booster pump problem, work from that and see if anything changed.

A motor overheating typically is from an improperly sized impeller or a motor fault.

Thanks. I replaced the volute on the booster pump and it’s working properly with no more leaks. The filter pump is ~6 years old and the impeller is not obstructed. I’m not sure how long these pumps stay in service. I know it varies based on care, but before I replace it I wasn’t sure if there’s something else I should check/test.

Sorry what does this mean? I can leave the housing and just get a new motor?

Yes. If you want to keep using whatever time clock you have to time your filtration, a Century EVQ225 motor will work with that pump if the impeller was never changed.
If you want more control over speeds and run times, a Nidec Neptune NPTQ225 will work. It has its own control built in, so the time clock for the filter pump would not be used, only the Polaris timer would remain in use.
