Hello all, I have some pretty tight quarters to work with here and need a submersible, compact, and powerfull pump to lift water constantly over 7 feet. I have a dutch aquatic system tank and it has internal oveflow built in to each tank. The system is three tanks stacked on top of eachother, with the top flowing to the middle and the middle to the bottom. The system looks like this.

Right now I am using a cascade 1500 as the sole filter and means for transporting the water. I would like to put the filter on another tank and clean up the look of this tank. I find the canister filter unsightly and since there is no stand to put it under I figured I should take advantage of the internal overflow that's already there. See how this looks.

The internal box has seperate compartments and I would like to house the pump in the last compartment of the bottom tanks box. These compartments are only 4.75 inches square and around 10 plus inches tall. The ideal pump would pruduce a flow rate of over 400 gph, and be able to lift the water 7 feet with no problem (you see mee in the picture I'm 6 feet so I'm guessing 7 without actually measuring). So any ideas???? Thanks.
 
The Quiet One brand pumps work well. I would say Mag Drive, but I think they are kind loud.

How much flow are you looking to get? What size are your drain lines?
 
My two main concerns small enough to fit into the space I have and ability to lift the water 7 feet. I have looked into all sorts of diffrent brands but nobody gives the size of the actual pump.
 
I also don't recall the pipe size I will measure when I get home (I'm at work now). The whole system is 190 gallons so I would need a min. of 400 gph flow more being ideal but I have to stay within the confines of the bulkhead size to I can avoid a overflow and then water damage. I will also post a picture of the inside of the tank sow I can show the overflow box. Thanks for all the comments.
 
Keep in mind "head pressure" is measured from the water surface in the bottom tank to the water surface in the top tank. So if you are 6' tall I'd guess you are looking at 5.5~6' of head pressure...

I have a very similar set up (48x18x21 75 gal on bottom with two 48x18x13 stacked on top, drilled so top tank flows into middle then middle into bottom). I use a SEN 700 gph pump and get around 300 gph flow with 4.75' of head pressure (measured as I described above).

I'll measure the pump in a bit (spare in garage) but I doubt it will fit in your 4.75 x 4.75 x 10 space. I would expect most aquarium pumps could handle that lift and would push about 40~50% of what they are rated for. Though naturally the exact flow will vary from brand to brand (based on strength of magnetic connection and size/layout of fins on impeller).

If you clink on the link I gave you and then the tab in the window that says "overview", you will see the size of the pumps.
 
I looked at the measurments on thos pumps and it seems they will work great so long as the first measurement is the from top to bottom with the outlet facing up. Does anyone know if this is the case here?

Oh and also the bulkheads measured from the inside walls of the bulkhead are just under 1 inch and all the tubing on the system is 1 1/4 inch (not that that matters) so how do I find out how many gph wil freely flow through the system. Because I don't want it to overflow by pumping up more water then the bulkheads and let flow down.
 
Sorry I edited my double post and deleated everything.
