Replacement pump for Ultima 2000 300G setup

I Need some in line return pump suggestions.

I have a 300 gallon tank with two 1.5” overflow pipes(actual pipe size) to a 2” pipe going into my in line pump then an aqua ultraviolet ultima 2000. It then goes to a 40w UV back into a 1.5” splitting into two .75 return tubes.

I’m currently using a reeflow dart gold setup 1850 gph at 10’ head. It leaked from the seal the minute I turned it on from the seal. I love how silent it is but I can’t decide if I want to get another to swap out when the seals go or if I want a different pump.

I have no clue what other pump to get. I’d rather not have have to keep swapping them back and forth every time a seal goes.

The ultima 2000 calls for 2000 gph at 10’ head ideal max 2500.

One pump I did find is the anjon land shark 3300 but that’s about 2750 at 10’ not sure how good or loud that one is.

This setup is in my living room the quieter the better
 
I use a Japanese Iwaki mag drive. I am not even sure when it is on, it is quieter than the water going over the overflow.
 
Below are the flow charts. I have got the 55R-5 running at 50Hz.

It looks like the 100R at 60Hz (assuming you are in America) would be about the flow you are looking for.

So I’ve tried finding the 100r, but I only seem to find the 100rlt? Which I woulda thought is the same thing but every website says it has a much lower gph even at 4’, idk if they’re just mislabeled
 
I don't know what the difference between 100R and 100RLT is. Possibly the American model and not the Japanese. Or are they re-labeled for the American market?
