advice for pump 15' head

[WeePee]

So I may be running my plumbing down to my basement (down 1 floor) for all the sump/equip needs. So i'll need a strong enough pump to make that distance (maybe 10-15' of head), and id plan to use an external pump.

also, anyone have good experience either plumbing through the floor or wall and have advice/links?

thanks!

Reef Central has a head loss calculator. You can plug in some of your plumbing specs, desired GPH figure, ect ect and work backwards by trying different pump options from the drop down.

I like blue line or panworld external pumps.

ok, still need some answers here if possible.

heres the scenario:

my drain is 1" (basically 800 gph), and my return is .75"
i have approx 12' of head loss.

does the pump i use need to match the sizes of my return and drain or can i use converters to get their sizes to match?

as pumps go, im currently looking at the ReefFlo Dart 3600 because the stats look good. but the inlet is 2" with a 1.5" outlet. BUT the drain on my tank is 1" and the return is .75" as stated above.
OR if anyone has specific suggestions, i need about 800 gph @ 12' of head.

also, the above calculator doesn't seem to have many of the pumps im looking at like the reefflow or the iwaki's.
