LF --> Small return pump + Calgary = Happy
 

Have a little nano system and want to throw into the mix a return pump. A small pump as something no larger than lets say 400gph (best would be around 200-300). The head is very short only 3' so I'm not concerned about loss of gph in this regard. I'd like to run this inline not submersed.

Great working condition is a must as I don't have spare parts. The more quiet and reliable the pump the better as this is for a bedroom setup.

Let me know what you've got and we'll go from there!

Thanks for the view

Just thought about throwing in a suggestion :)

Why not get the 790 DC pump and run it at your preferred rate with the controller? Return pumps that people use most commonly go above 600gph, which with a 3' will give you around 400-450gph.

It is a good suggestion...I'm just trying to keep the amount of hardware at a minimum. Don't have a controller so I'd need to buy 2 things to have a dc pump.

The controller comes with the pump itself :D You won't need anything other than plugging it in the outlet and using pipe to connect to the return.

the new dc pumps such as the ones concepts sell (speedwave) come with a simple controller to adjust the pump's speed. you only need to buy the pump. very happy with mine so far.

Just took a look and it's more than I wanted to spend on a nano tank for a return pump. I guess I'll have to cruise the LFS and see what I can see.

What's the reason for needing inline ? Most pumps like what your after will be submersibles

To have as little heat added to the loop. If anything a chiller is needed than any sort of heat source.
