reeflo dart hybrid for basement sump

[drabber]

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.

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.
