IMO, the eheim 1262 would be a bit much for just the return, but if you bleed off 400 gph for the reactor, then it may work.
I like having a single pump for a single chore. That way if it goes out it only takes out one function. But that's just me.
I use a eheim 1262 on my 240 as the main return pump.
I've never used the 5000, but doing a google search tells me that it pumps 1320 gph and IMO that's way too much for the two functions.

The 1262 is an excellnt choice. It should provide you somewhere between 5 and 7 times the display volume return flow after headloss and still have enough to run a reactor which is not going to take anywhre near 400 GPH to operate. I used the Ocean Runner 3500 which has almost identical specs as the 1262 for over a decade on my 100G which has a 5-6" Soutdown DSB and it was never an issue. I even increased the flow a little with my current WaterBlaster HY-5000. Always install a ball valve in the return line so you can throttle or adjust return flows to suit your needs so even if the pump is a little too large you can add a little head and reduce the flow, reducing power consumption and heat generation and often making the pump quieter and more efficient.
Why not baffle your refugium so your overflow or return feeds it? I have a 1"x1/2" tee in my overflow with a 1/2" ball valve so I feed my refugium with the nutrien laden water which then oveflows a tall baffle back into the center/skimmer section of my sump so no additional pumping is required. I do feed my two phosban reactors (one GAC and one GFO) with a MJ 600 powerhead via a tee and individual ball valves so they can be controlled individually or even taken out of service without affecting the other but have though about building a manifold but its one of those things I haven't gotten around to.
Probably not but I got in a power conservation mode a few years ago and was amazed at my home power bill savings by changing to fewer, more efficient pumps, eliminating the chiller and fans and going to LED lighting. It really made a big difference and I documented it in a thread at www.azreefs.com .
Are you saying your refugium and sump are not connectedso have seperate overflows and returns? Why not bulkhead between them if they are on the same level or have one aove the otheroverflowing into the lower one then returned tothe dislay with one pump? Doesn't sound very efficient? Or find a larger sump which could also house a refugium, mine is a 30G long with the sump off one end ovrflowing into the main section then over-under-over baffles to the return section. Takes up 18x36" but has lots of surface area and room for equipment.

A tall sump or refugium is a challenge since it has less surface area for equipment, oxygen transfer and baffles plus it a bear to get a skimmer in and out of. It is
also tough since most skimmers only like say 9" of submersion to work well so you end up makimg a platform for it to sit on then getting the cup off is a PITA.

I have an Eheim 1262 in a 70 gallon cube. I use a gate valve to throttle it back to about 600 GPM. The output of that pump is 1" I believe so a 1" return will work fine. Use a gate valve for finer flow tuning. I believe that it consumes 85W. So factor that in as well. I love this pump.

thank you all for your help! 
i have another question, what would be better eheim 1262 or the eheim 5000 compact? Eheim Compact+ Pump 5000 - Bulk Reef Supply or Eheim 1262 Universal Pump (900 GPH) - Bulk Reef Supply
