4 x 100L DWC containers pump suggestions needed

[Title should be 2 x 100l] Hi everyone, Need some advice about my set up im planning. I want to have two DR 120s with a 100litre converted Igloo Cooler in each for DWC. I have found all the equipment except for what pumps im gonna use.

I was looking at getting a GH dual diagphram pump and these are the stats 3 psi, 320 gph. Will this be enough for the 2 100litre containers. Each container would be in a seperate DR 120 which is 1.2m x 1.2m. Can the pump go outside between the two of the tents and pump air into both these containers and more importantly give me enough bubbles for them or will i need one pump per container. Will the air tubes coming out of the pump reach into the tent? How loud are these pumps and is there anyway to make them quieter. For example I have seen people massively reduce the sound of fans by placing them in boxes and surrounding them with blankets etc and seem to have killed most of the sound. Is there anything similar with pumps.I haven't actually ever seen a pump or hydro set up in action so im not sure of my requirements here. I have heard that you should hang pumps to stop the vibratings and to stop them flooding if the power goes but how much noise does it make even when you have it properly suspended etc. Thanks for reading and answers

that pump would probably be a quiet choice and big enough but I like commercial ecoplus pumps myself. dude at my hydro shop says the gh is a good pump.
Good call on the coolers, wouldn't mind seeing pictures.
