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.
