View Full Version : reeflo dart hybrid for basement sump

02-22-2013, 09:18 PM
hey everyone.
i have a question regarding a basement sump build im working on. i have a reeflo dart pump in transit to finish my 125 gallon 40 breeder sump build. but i was talking to the owner at my lfs and he said it wont have enough gph to over come the head pressure and get the output i want.

i was going to run a 1 inch off the outlet straight up 10 ft with 1 90 elbow.
i want 500-600 gph. and the pump in dart mode is rated for 650gph at 12ft of head pressure.

think this will work?

any help is appreciated... thanks!

I would trust the published rating before the LFS. My ReeFlo pump performs as advertised.

I wouldn't trust the pump for 10 foot head. It's max 12 foot, and with unions/valves/elbows I think the most you'll get is a trickle out the end. I would go bigger. Just my 2 cents.

I had that pump running 6 feet and it was great. I sold it to a guy that was more like 10 feet and he sold it right away because it just trickled out the end of the pipe.

ill be using a ball valve union all in one and trying to see if i can set it up so as to not use a checkvalve on the return line to reduce head

To be conservative I'd double your static head (10ft) to get an idea on what your total head pressure will be, especially with 1" pipe which will add decent friction losses. I think you need a bigger pump personally.

If you can find a similar pump on the list you can use the calculator on reef central to be more precise.

I didn't realize a Dart' max was 12', that's a bit tight.

Actually looks OK according to the calculator. I expected higher friction losses but I guess the flow rate is low enough.


I'd use at least 1-1/4 though as it'll form a layer of build up on the inside of the pipe overtime shrinking the diameter and creating a rougher surface. Calculator is based on clean smooth pipe.

^^^ nice thanks for posting that! I couldnt get it to select a pump on my mac.
I am still skeptical myself, really wish i went with a larger pump.. thats allot of work to go through to find out it doesnt work lol...
looking into raising the stand for the sump a couple ft, as its a low stand to begin with.

I am running the hybrid Dart from my basement sump room using 1 1/2" pipe approx 6 feet up then teeing off into two 2 1/2 foot 1" lines (total 11' head pressure) and I am getting approx 600 gph turn over. It has worked very well for me as I have two MP40's to get the water moving inside the tank. I would say go for it!!

^^ Nice!!! seems promising. what size did you run into the tank 1 inch? or did you reduce at the bulkhead to 3/4? i also have mp40s for my setup :)

I just went 1" nozzles at the bulkhead into the tank. You could reduce it to 3/4" if you prefer. :smile:

well im going forward with this. did some work with that calculator... going to run 1.5 up into a 1.5 header with two 3/4 branches into the tank. calculator says i should have around 1000 gph. even if i get 650 ill be happy!

also for my first thread on this forum i am really surprised / impressed by the amount of helpful responses ive gotten!! thanks again everyone!

thought i would update this now that the tank has been running for a while. so its providing the flow i want in snapper mode!! i couldn't beleive it. i hooked it up in dart mode and was going too fast for my liking.

Glad to hear its working out for you! :)
