You'll need a 24vdc PSU like this..S-100F-24, Mean Well S-100F-24 ..Hopefully you'll be able to trim it down to 18-21vdc with the rheo on it, everyone I've had are a little different, just luck of the draw. The RD 30 runs to hot at 24vdc so you want to get it down to around 18vdc if you can, I know a lot of them are running around 21vdc and they seem to be doing OK.
I'd at least go 5/8-3/4" from res to pump, you want to keep a good sized suction line if you can at all. Then go with 1/2" on the pressure side.
Here's how I set up my AC Iwaki so that the pumps intake is fed with 3/4x1.25" tube from res to pump, then I have a special block with a 3/4" inlet barb that I run. But anyway keep as much water stacked on top of your pump with a large inlet tube, I wouldn't use 1/2" for that, I'd think it would have to hurt performance, I know it would make the pump work harder and probably run a little hotter because of it to. This is a TEC rig or I would run the pump through a rad before going to CPU but with this rig it doesn't matter.
It's really important to give your pump a easily accessible supply of water on the intake side, I have a sealed 5 gallon bucket res over the top of this 20RZ for that reason. You don't have to go that big at all but I would use a decent sized res with a large intake tube. Stand the pump vertical like tht if you can at all, you may even be able to make a res right on the pump inlet.

Not geothermal, but I am relocating the radbox to outside the house, for some Maine winter cooling. I am using a car radiator, and a few blocks on my 655, and I like the idea of the higher pressure, even with the increased plumbing length.

Thanks, this helps a lot. The pump (and the water running through it, of course) will be out in the winter air, if that helps.
