Slightly broken Impeller - do I need to replace it?

[nikon5400]

I broke it when tried to get it out.
Do I need to get a new one? Or should I glue it (if so, which glue?) or should it be fine as is?

Thanks

Replace it! Imbalance will knock your pump bearings out, and glue won't hold up.

Do you think it'll still have imbalance with (white) ring on it?

This impeller is no longer manufactred, finding new one may be a challange. inopools and a few other places I checked haven't had it for a while

thanks.

If you have no choice, it's an outdated pump, then yes, I'd go for it for sure! You might try some good epoxy and see if that will hold.

I'm having second thoughts about glue - if this piece breaks loose can it get stuck in the heater? this broken piece is up to 3/4 inch.
Thanks!

P.S. It looks like the broken piece may get stuck in impeller, which may contribute to imbalance(?)

Yes, I agree.

get stuck in the heater?

put your heater in your signature please.

You bought yourself a new pump. Replace it if you cannot find an impeller.

You cannot glue that together and expect it to hold.

Sorry, replace what? Impeller? Do you think my impeller (pictures above) should not be used?

I didn't buy a new pump......

I'm not sure what I'm doing with pump motor yet. I have an offer to rebuild mine (new bearings) for $125 (if reparable, otherwise I'm out of $95 diganostic fee) or go with a slightly used motor, different model (smaller
in diameter, same HP) for a very good price.

Take the used pump. At the 3000 RPM or so that a pool pump spins at, any type of adhesive, epoxy or any other type, will not hold. Also at that speed the imbalance will cause your pump to shake itself to death, sooner rather than later.

That is NOT a "minor crack"

I agree, I corrected the text I guess after you replied.

But do you think with white ring over it it can still cause issues?

 

[crusemm]

what part is that white ring?

Cut the bad part so that it is more uniform and then cut the opposite side the exact same way so that the impeller is balanced.

I still think that is too risky. My experience is not with pool pumps specifically but with larger pumps in industrial applications. In my experience, damage like that isn't worth trying to repair and would almost certainly cost more in the long run in time and equipment damage. However, YMMV

The impeller ring you indicated is a wear piece, and meant to be replaced eventually. However if it's not damaged, and it doesn't look like it from the pictures, then it would probably be fine to reinstall. The part appears to be pretty inexpensive, so if you can find one, I think it would be worth it to replace it if you can.

What I meant was - if existing impeller with impeller ring is still ok to use.. This impeller is hard to find, even places that have it "in stock" don't have it. I'd assume some repair shops may have used ones, will try to locate them.

thanks.

All you have to do is cut the opposite side to match so that the impeller is balanced.

What's the risk?

Have you done something like this and had it work? Not trying to be snarky, I really am curious. I would think it would be impossible to get the balance even close to tolerable, and the unbalanced operation of the impeller would quickly destroy the motor bearings, shaft seals, amd wear ring.

You don't say which Hayward pump you have. Buy a 1hp impeller and use it. You would be happy with the performance. 2hp full-rated pumps are too much pump for virtually every system out there.

I got a call from Hayward, had question about pump, shaft seals and an impeller. Guy looked at these pictures and said it should be fine, shouldn't cause imbalance. The largest size of the piece that came off is 1/2 inch.

Since there's no inventory for this item anywhere, I guess I'll take my chances.

I'm debating whether I should use an old motor which is very loud or the new one... this way if you guys are right, it'd do more damage to the bad motor

I hope is this part surfaces on ebay one day

Thanks!
