I have an old 1.5 HP single speed 240 vac Hayward super pump.
Is there a variable speed pump that is a drop in replacement as far as size and positioning of the inlet/outlet fittings?
I’d like to replace my pump but not have to re-plumb. The inlet would be the biggest concern. No room there on the existing plumbing to modify. The discharge side however I could re-plumb if necessary but I’d rather not.
Is there just a motor upgrade I could do also? Keep the pump housing and just retrofit the single speed motor to a VS?

That’s a huge savings to retrofit. But two of them failed within a month? Yikes. What failed, the motors or the controllers?
 
Check the service factor on the motor plate of your 1.5hp pump. If it says 1.1 (an uprate pump) you can install the 1.65 V-green. If it says 1.5 (a full-rated pump) you can't as it will fail.
If the number on your impeller is SPX2610C you can use it. If it is SPX2615C you can't.
 
My motor was replaced about 5 years ago on the Hayward. It now has an Emerson EB796. The plate says 1.5HP. S.F 1.30. 3450 RPM.
Then under that is says 1.5 SF 60hz
 
That's always the problem with finding a replacement motor on a pump. You will have to get the number off the impeller to be sure. If a repair person hasn't taken a class or the time to understand what the service factor of a motor means, they will replace a motor based on the easiest number to understand. An uprated motor and a full-rated one may both say 1.5hp but can be over .5hp different in total horsepower. A true 1.5hp impeller will load the motor to at least 2.1hp to 2.25hp depending on the motor. That will burn out a 1.65 V-green as the 1.65 is the total horsepower it is capable of producing without damage. Again, if the number on your impeller is SPX2610C you can use it. If it is SPX2615C you can't.
 
Understood! Thanks for that explanation.
I also see that inyopools offers a kit with an impeller in it. Would that be a suitable retrofit ?

They appear to be a reputable company. Many here have had good results with them. If they have matched impeller to motor size, which it looks like they have, that is a great deal. I don't deal with retail, but can tell you that is very close to what I would pay for those items at one of my wholesalers, maybe even less

There is a way to use that motor with an existing time clock. It can be found on Century's website and YouTube. Variable-speed motors behave differently from standard ones and take getting used to.
 
Thanks. A bit leery since Phiber23 says he went through 2 of them. That’s concerning unless he had the incompatible impeller as you pointed out?
I’d like to hear what his failure scenario was.
Or I bite the bullet and do as Pool_medic replied above and get a complete drop in Hayward VS unit. But that’s like $1300.

On the other side of the issue, I have installed somewhere around 20 of them and never had a call back. Need to find out why they failed before condemning the whole brand. I still suspect an impeller/motor mismatch, though there could be other causes.

Also, nothing is as good as new except new. You say your pump is old. How old? While it is very good plastic, the "wet end" is just plastic. The average life-span of pool equipment is 15 years. Other things can happen to the pump beyond a failed motor. The prices you see online for these pumps at most places are true wholesale prices, I just checked my supplier's website.
 
The pump is 22 years old.
I take it in the house each fall when I close the pool for the season. I don’t like that stuff sitting out in the snow and ice.
 
Might be time to consider new. Not knowing how pools are operated in your area I'll guess at 6 months each year. If that is so and you filtered about 6 hours a day there was likely somewhere around 80,000,000 gallons of chemically-treated water that has gone through the wet end. Yes, 80 million. That's just one aspect to be considered.
 
Interesting calculation. So I did my own based on time and my actual water flow. (I have a FV-2 gauge inline). I came up with 92,000,000 gallons. Wow. I’d go new,
I just wish the price difference wasn’t $550 vs $1300!
Gonna have to think about this one.
 
Another little tidbit... 1poolmn1 had me wondering, So I pulled the motor from the housing today out of curiosity to see which impeller is in there. (Yea,. I do crazy stuff like that at times). It is the SP-2610C. Is that a mismatch for the Emerson motor I have been running for the past several years? The motor has a 1.5 SF rating. If I understand correctly it is fine. But want to be sure.

I believe the controller is failing. The first pump worked for 2 days then whenever I would apply power it would turn on, none of the buttons would work but it would start running for 2 minutes at max speed, then turn off with the fault blinking. The second pump lasted for a month and then the same thing happened. Inyopools has been great and helped me with both failures and are offering a full refund. They say my power (246v) is too high but it is within 10% of 230v which seems to be normal from what I gather on the web.


I'm going to replace the whole thing with a new pump and motor. Anytime I try to go cheap with this pool I end up paying more in the end.

This is why the new DOE regulations are going to eliminate confusion, and I'm not a big fan of more regulation.
The original motor that came with your pump was probably labelled somewhere with 1.5hp. But it was a 1.5hp uprated pump. I know that because the impeller you have is a 1hp full-rated impeller. Whoever replaced the motor just went with the label and installed a full-rated motor. Many times the original motor that came with a pump had the true hp and service factor left off the motor at the manufacturer's requst. You had a smaller impeller than the new motor could safely handle, no problem. That means, among other things, that a 1.65hp V-Green would work if you want to go that direction.
