Questions on changing to a 2 speed motor on a Hayward Super II pump

[keastman]

Anyone have any suggestions on where to go on this?

I've got another pump motor question. My Super Pump II has a 2 hp motor with a sf of 1. I've found a 2 speed 1 1/2 hp motor with a sf of 1.3. If I calculated correctly that's a hp of 1.95. Would that be a near equivalent of my present 2 hp motor, or am I not understanding the sf comparison?

Are these they?

So far, this is merely a reference post. I'm asking Mark and Al to take a look.

Ben, those are pictures I sent you a while back, but I sent the ones you requested of the pool, spa, and quick clean controller a couple of days ago. I can resend them if they didn't make it. Thanks, Kevin

That is why it is always a good idea to reference the url of the thread so the pics get matched up with the right thread. Hopefully, he'll find the new ones you sent and get them posted for you.

Yes, it is pretty close and would probably work ok since it is so close. One thing to look at is the max amps rating of both motors to see if that is close as well. Manufactures build in some margin into the label ratings so there is a little bit of head room but you don't want to push that too far or the motor will overheat. You would be better off getting a motor that is slightly too large than one that is too small.

As for the two speed motors with timer, personally, I would not think the timer on the motor would be all that convenient but that is your choice. But my biggest concern would be reliability. Emerson was not known for producing high quality motors and their motors usually end up on low end pumps. But it is a great price and it might be worth the risk.

I wasn't thinking convenience; I was thinking cost. Instead of a $500 motor + a $150 timer, the Emerson motor was just $275 -- less than 1/2 the cost for the same function.

I didn't know about the reliability problem -- I've only dealt with a few Emerson motors, and didn't have problems with those. If you have more info on that issue, could you email it to me? (I don't want to hijack this thread.)

I might be the guinea pig for the site and go with the 2EZ motor. I'll just need to make sure it's not old stock from the recall period. At sub $300 it will be a bargain if it works out, if not, I'll wish I invested in an AO Smith, or a new two speed Whisperflo, or Intelliflo pump. Time will tell I guess, I'll keep ya'll posted how it works out if I go that way. I'm a bit hesitant on the electronic controlled timer on the pump with all or our lightning here, but I put a surge protector in my pool panel. I don't know if it's coincidence or not, but I haven't lost any components of my SWG since it's been installed and I used to loose some part yearly before I installed the surge protector. I do like the timer on the EZ pump because it has freeze protection and we get 5 or so freezing night each winter in NE FLA and sometimes I forget to run out and turn the pump on overnight, or don't even know it's supposed to freeze. Not having the expense of buying another timer and time spent wiring it will also be a plus. Hopefully running that pump on low most of the time and adding the 340sq ft filter I picked up will help keep the water cleaner. I think the 2 hp motor I have now is blowing a lot of fine stuff through the 120 sq ft one I have.

Now I just need to figure out a good plumbing plan to clean up the octopus system that I have now when I put the filter on line.

Thanks for the input and any other advice.

Call and ask, but it LOOKS like that if the electronic timer fries, the motor may live. And, if it does, you can bypass the on-pump timer with an external timer.

Kevin,

My apologies, but the pictures you sent came in differently, and weren't caught by my filters.

I've got them loaded: where do you want them?

Meanwhile, I noticed a problem. I grabbed this detail from one of the pictures:


That is almost certainly NOT a Hayward OEM, and not a Unicel or Filbur aftermarket. I'm running into info that Chinese and other low-grade carts are coming into the US market in very deceptive ways. For example, this IS a genuine Unicel: Unicel C-8412 Replacement Cartridge for 120sft Hayward CX1200RE @ Amazon

But this: Hayward Replacement Cartridge Element @ Amazon is almost certainly NOT a Hayward OEM . . . even though it's cataloged by Amazon as being one.

And this one: Pool Filter Replaces Unicel C-8412 (Pleatco PA120, Filbur FC-1293) @ Amazon is not even close!

In your photo, the replacement has no bands -- this almost certainly marks it as a VERY low grade replacement, not even up to Pleatco's standards. That may explain a lot of the difficulty you are having clearing your water!
