Can't find variable speed pump motor (1.5hp) - Help

My pump motor has finally given it last:
Emerson U.S. Motor, square flange
1.5hp - full rate
230v
Connected to a Supatuf pump.

After reading about variable speed pumps, especially those with digital controllers, I got excited and started searching. Found inyo pools had one listed, but talking to them, it was discontinued in my size.
I am finding nothing else that will work, not even two-speed pumps. Only single speed direct replacements

Is there an source for a motor that will fit?
Is there an aftermarket device, maybe built into a timer, that will reduce the flow rate of the pump through the motor (like a rheostat)?
Any advice appreciated.
 
It's a Waterco Supatuf Pump.
According the guy from inyo, they have discontinued a lot of the motor models that fit my pump. They do have one motor that is 1.67hp and the next jumps to 2.7hp. He did not recommend either, and said I need a single speed motor, the USQ1152. While I certainly appreciate that it is half the price of the motor I wanted, I would rather have a variable or at least 2 speed.
 
Maybe post a picture of your pump and set-up. I cant imagine a situation where a Pentair Superflo VS pump wont work . They are about the only 1.5hp VS pump that can accept 115v or 220v , and easily adapt from either 1 1/2" or 2" plumbing .

Maybe forget about trying to just replace just the motor, and replace the whole pump . Will pay for itself in no time.
I just purchased a new Pentair Superflo VS for my system for $598 OTD with no tax or shipping. I will give you the website name if you are interested .....

If you have my luck, I would replace just the motor .......only to have the pump go bad a month later , lol !

Just go with a whole new pump !
 
Here you go. I had to remove the pump as the inyo rep wanted me to get a part number off the impeller. Of course it is coming off the left of the pump, sitting on the frame mount.

I dont see why you couldnt put a whole pump in instead of just a motor. You have plenty of PVC to work with .......... nice open equipt pad. Doesn't look too hard at all to work within your pad .
Pump looks to be approx 10 years old already ?
Maybe time for a whole new pump/motor replacement ?
 
Thanks everyone.
This setup is 9 years old, this summer. When I was getting specs on the motor, the distributor said that motors of this vintage, and newer, should last 3 to 5 years. (He said the casting are much lower quality than they used to be.) So I guess I got more than they expected.

How long does the actual pump part usually last?
 
I agree with what others have said about replacing the whole pump/motor. I just went through this same situation this week - old single speed motor died. My local utility is giving $400 rebates on variable speed pumps. Take that off the $650 I paid and it cost me less for a whole replacement than just a motor. Plus it is easier to install, took 45 minutes.

Duke Energy requires this:
"•Your new variable-speed pool pump must be installed by a participating contractor and operable before you submit your rebate application."
It would cost me more to have a contractor install it than what the rebate is worth.
 
I'm very interested in knowing the website where you got rhe Superflo for $598 OTD. Thx
