Pump Woes

[Poconos]

Just to set the record straight, there are no brushes in these motors. Brushes are used in DC or AC/DC motors with a commutator. However there is a centrifugal switch in the back end of these motors but that doesn't seem to be the problem since the shaft is seized, or at least tight. That motor looks pretty beat and in that condition, with the corrosion around the cord entry too, I'd wonder what the condition is of the switch and centrifugal assembly which is in the rear under the back cover. I'd go for a new pump. Your time is worth a lot too and you could fuss with this thing and still not have a reliable unit.

Thanks everyone

I tried plugging in just the motor without the pump. The shaft did not spin (but it did hum again). I unplugged it and tried one more time to confirm. Same thing although this time I did hear a grind/grumbling noise that lasted for a second or so.

As far as how loud it was when it was running, it's hard to say because I had nothing to compare it to. First time pool owner (just bought the house). However, I found it to be loud.

You guys called the white powder oxidation, and you're probably right, but it had crossed my mind that it might be DE. Possible?

So, I guess the conseses seems to be that I should just replace it. The motor itself I found for $180. The whole pump I found for $280. Being that it was suggested to replace some other parts too, I may just buy a whole new unit and save myself some headaches.

So, my only real question is, what happened here? Did this just get old and was time for relacement or was this used improperly, or maintained improperly? I just want to know so that it doesn't happen to my new one either.

Thanks a ton guys!

Null, as you are still on the forum, I guess I caught you before you went to the store. My $ quote was based on what our store would charge ($240 for the motor, $15 for the seal and $4-5 for the housing gasket). You are getting much better prices wherever you're going, a new pump would be over $400 from us. That said, save yourself some hastle and get the whole pump, I was trying to save you some $, but for $280 the new pump makes sense.
Al, thanks for the education, I've only seen the inside of the motor once (~1990) and was told that there were brushes in them - sorry for disseminating BS
As to a cause for the failure, poor maintenance. A lot of folks keep all their pool stuff together for the winter, pump, filter, skimmer baskets, etc as well as thier chems - including tri chlor tabs. As I said before, even tightly sealed cl will vent off and oxidize all metals in the area - add a compromised shaft seal (with the often acidic water from using tri chlor) ... and it's rust city!


Good luck with the new pump, you probably won't need it but, if any advice is required to get the new one in, just ask - that's why we're here

OK,
Your motor is plastered--I seriously doubt that's DE--looks like corrosion to me.

You'll need parts to get the pump back together, and then either need a new motor (doesn't have to be Hayward) or a repair job. Plus there's the time element where your pool has no filtering.

Sounds like an IDEAL opportunity to upgrade. That doesn't mean a more powerful pump--it means a pump that is quieter, more energy efficient, and maybe 2 speeds (once you have a 2 spd pump you NEVER want a single speed again!). You may even be able to use a LOWER HP pump and get the same performance.

Thx everyone. Waste I did get your message before heading out. Thx for the advice!

Sorry CarlD...Headed to the store before getting your message unfortunately so I hadn't even considered a dual speed or even any other pump. Just bought the same one as I had before. It's the Hayward Super Pump 1.5 HP. Before I open it, are you thinking I should return it and get something else instead? Paid $297 with tax. I had just assumed it was a decent pump since I had read about so many people owning them. I obviously prefer not returning it but if you think I made a mistake here, then I would.

How many gallons in your pool and can you see a gpm rating on the filter? (or find that rating on a web site)

Those two things best determine the size of your pump.

[NullQwerty]

It's a 36 X 18 foot inground vinyl. Deep end is 8 feet and shallow is 2 or 3. So, my guess is about 24,000 gallons. The pump is the Hayward EC-65 which is 67 gpm.

Edit: 67 gpm was specs from the internet. The filter itself says Flow range is 35-65 gpm
