Do you want a new pump or just a motor?
What flow do you want and need?
We can't really recommend a pump without knowing what you want and need the pump to do.
We can't assume that your current pump is properly sized for your system and your needs.
Do you have automation?
Do you have a heater?
Can you show a picture of the system?
Can you provide the details of the pool?
Are you trying to keep the cost as low as possible?
Do you care about the noise or operating costs?

Why are you so adamant about NOT getting a variable speed pump?
What is the supply voltage, wire size, wire length and breaker size?
Is the current breaker GFCI?

James. Thanks for reply. I’m looking for a new pump and motor. I’m looking for the next generation replacement for the sta rite dyna glas which they don’t manufacture anymore. Pool is 40x20.
Flow is great. It is properly sized. I have a heater that I don’t use because of propane cost and floor system.
We usually get 10-20 years out of our single speed pump and motor. I’m not looking for variable speed and automation which just begets more problems.
Thanks for the feedback.

What is the model number?
Is it one of these?

Most single speed pumps are no longer available due to the new regulations.
The 348185 Max-E-Pro Pool Pump 1.1 THP NEMA Premium Efficient TEFC 115/208-230VAC at 60hz 0.61 HHP is probably the closest you can get to your current pump.
It will probably underperform what you have now.
I can’t find the head curve for your pump to confirm the performance.
Here is the head curve for the Max-E-Pro.

Even though you say that you don't want a variable speed pump, I am still going to recommend a variable speed pump.
In my opinion, an IntelliFlo VSF would be a good choice.
You probably don't need the amount of flow that your current pump is delivering and it just wastes electricity.
Note: The IntelliFlo VSF might require a new power supply depending on what you currently have.
In any case, it's your choice.

Pictures please. You haven't stated how the pump is wired 115/230.
You say that you have a floor system, which typically requires a specific amount of pressure and flow.
With a variable speed pump, you can deliver the same pressure and flow, but you still are likely to be overpowering the system and costing more in power than necessary.
The new 348185 Max-E-Pro Pool Pump is likely to be louder than your current pump due to the external fan on the TEFC motor.
The fans tend to get annoyingly loud at speeds above about 2,400 RPM to about 2,750 RPM.
The single speed pump always runs at 3,450 RPM and the fan is loud and whiny.

There's also no reason you have to stay within the same brand to get more bang for your $$$.
The Hayward Tristar or the Superpump might be available.
Your current total HP is 1.65 and I don't think that you will find a 1.65 total hp pump in single speed.

Your old Dyna Glass was/is a medium head pump. The Max-E-Pro listed below is your best option that you can find that meets DOE requirements if it is legal in Massachusetts. It is a high-head pump that should be able to run your IFC system.

Thanks everyone for the feedback.
I'm just frustrated with the new regulations. Single speed pumps have always served me and my family members well, with a life of nearly 20 years. I usually run my pump between 6-12 hours a day. I am in New England so only from May -October.
With the high upfront cost of variable speed pumps, the fact that I will never be running them on a reduced speed (because it doesnt provide enough pressure for floor system), it doesn't look like it is going to save me any money. I don't think VSP will be saving anyone any money really. Variable Speed Pumps (VFD's) are a Scam – Cycle Stop Valves, Inc..
"As they say, the Devil is in the details. Read the fine print carefully. Comparing a VFD to the most inefficient pump system possible is the usual way to show it saves energy. Many articles will barely mention discontinuing the use of a dump valve, lowering the pressure required, or even installing a smaller pump in the system. Although these are the real reasons for the documented energy savings, the VFD added to the big pump wrongfully gets all the credit.
So called "energy saving calculators", especially for pool pumps, will not allow you to simulate turning the pump off. A pool pump only needs to run 6 to 8 hours a day. If you can't turn the pump off, of course a VFD is going to show $2,000 a year savings. But slowing the pump down with a VFD is not doing any good. At really low flow rates the skimmers don't skim, the vacuum won't vacuum, and the filter won't filter. Turning a standard pump off with a timer, instead of letting a VFD run it slowly all day, WILL save thousands of dollars a year.
Other so called "energy saving calculators" won't let you put in the head or pressure required. This way they can show tremendous energy savings when the pump speed is reduced by 90%. However, because the pump still has to produce head or pressure, the pump can only be slowed by 10%, which actually makes the pump use more energy than a properly sized pump without a VFD.
Still others will make a big deal about how the motor amps are reduced as the RPM is reduced with a VFD. However, they conveniently forget to mention that the flow is reduced 5 times faster than the amps, which makes the VFD cause 500% more energy use per gallon."
That is not correct.
If the flow is half, the power is 1/8th according to the pump affinity laws.
If the flow is 1/3rd, the power will be 1/27th.
If the flow is 120 GPM at 3,450 RPM, the power is 3,000 watts and the head is 67 feet, then at 1,725 RPM, the flow will be 60 gpm, the power will be 375 watts and the head loss will be 16.75 feet.
If the flow is 120 GPM at 3,450 RPM, the power is 3,000 watts and the head is 67 feet, then at 1,150 RPM, the flow will be 40 gpm, the power will be 111 watts and the head loss will be 7.44 feet.
One turnover of a 30,000 gallon pool at 3,450 RPM would take 4.17 hours at 3,000 watts and it would use 12.5 kilowatt-hours.
One turnover of a 30,000 gallon pool at 1,725 RPM would take 8.34 hours at 375 watts and it would use 3.1275 kilowatt-hours.
At half speed, the time is double for a turnover and the total energy required is 1/4.
One turnover of a 30,000 gallon pool at 1,150 RPM would take 12.5 hours at 111 watts and it would use 1.39 kilowatt-hours.
At 1/3rd speed, the total time is 3 times as long and the total energy required is 1/9th.
If you plot your system curve on this graph, you can see what your flow will be for each speed.

Looking for some help with variable speed pump energy consumption
Hi All, I have the Waterway Power Defender 140 1.4HP Variable Speed Pump PD-140. We have 1 skimmer, 3 return vents, and a Zodiac G3 pool cleaner. The run schedule when I moved in was set at 3450 RPM (max speed) for 4 hours from 8am-noon and 1250 RPM for 12 hours from 8pm-8am. I have found that...

Thats nice and all. But they want you to keep the variable speed pump on 24 hours a day. But at the lower speeds, my floor system doesn't work.
The end result is that if I buy a variable speed pump, I'm going to pay more up front and be running it like I would a single speed pump at the highest speed for 6-12 hours a day. All I'm getting is a higher up front cost of purchase.
I also get a kick out of the cost per kwh at .12, its currently at about .48 per kwh in MA.
“There are three kinds of lies: lies, Darn lies, and statistics.”

Floor systems are a horrible design and they waste a lot of power/energy.
A pool with a floor system might be the only pool type that will not benefit from a variable speed pump if you need to have only high speed and power.
The 348185 Max-E-Pro Pool Pump 1.1 THP NEMA Premium Efficient TEFC 115/208-230VAC at 60hz 0.61 HHP is probably the closest you can get to your current pump.
If you went with an IntelliFlo VSF, then you could probably run slower most of the time even if the pop-ups are not creating a lot of force.
You might only need to run at higher speeds for and hour or two.
In any case, you should have enough information to make an informed decision about which pump will work best for you.
