Mounting Dual Aquacomputer D5 Pumps with Aquabus Interface – Custom Mounting Brackets
I want to be able to control the speed of the pumps through the Aquabus interface on the Aquaero 6 which is why I selected these pumps. No need to use up a fan channel this way and no fooling around with a little red knob on the bottom either.
I know many people just set their pump speeds then never adjust it again, but I want to be able to play with the pump speeds so I can chart out flow rate and temperature differences at different pump speeds.
The pump top I chose is the Bitspower Dual D5 Top - Acrylic version Model # BP-2D5TOPAC-BK. I chose this top strictly because I really like how it looks! This top was unavailable for about six months, not sure why, but it's back available again now.
Then I picked up a pair of Bitspower D5 mod kits to cover the pumps with. I really wanted to get them in chrome or “silver shining” as Bitspower calls it, but either they don’t make them anymore or nobody on the planet had them in stock when I needed them. So I ordered them in matte black instead.
Also these mod kits are designed for regular D5 pumps and not the Aquacomputer ones with USB and Aquabus connections. There are four additional plugs on the bottom of the pumps, so I cut a square hole out on the bottom plate of the mod kits.
Here’s the Bitspower mounting brackets for this pump top. It’s designed for mounting on the bottom of a case, not over a radiator with fans like I am doing. There would not be enough clearance underneath to plug in the USB and Aquabus connectors, plus they would have to bend in somewhat to get them to line up with the mounting brackets on the two fans.
You can also see here that I took the mod kits to the chrome shop. The bottom plate is polished and the pump covers were chrome plated.
I also had one of these style pump brackets laying around, this one is too low as well, and I really don’t like how the bracket sticks out over the edges of the pump top.
So… I decided to make some brackets that will fit my needs better. I bought a 6” x 10” scrap piece of 1/8" 5052 Aluminum Sheet on ebay, took it over to my Dad’s house and had him cut it into four pieces on his table saw. This gave me three pieces the right width to match the pump top, plus one piece that's slightly too narrow, but I'll use that one to make a practice bend with.
I bought a mini brake that fits into a vise. Whenever I have needed to bend metal in the past, I just put it in the vise and hammer it over, but I’m looking for a cleaner bend here.
Make sure to get the piece straight in the vise or you’ll end up with a crooked bracket. I used a small level on the side. Here’s half way bent.
Fully bent here. I'm a pretty strong guy and I could barely complete this bend! 1/8" sheet is certainly the max thickness that can be bent by hand in a vise.
It came out with a nice 90 degree bend.
The brackets looked kind of plain with straight sides, so I decided to cut some curves into the brackets similar to how the Bitspower brackets were. Using a jig saw, some files and sand paper here’s how they look now.
The pump covers stick out beyond the edges of the pump top. There is a Tap Plastics close to me, I had them make the small pieces that will serve as spacers between the pump top and the brackets.
Here is the back side of the pump top, there is two holes for 3mm LEDs. I’ll put two white LEDs in there. The second plate holds the wiring in place.
Here I have two Darkside 3mm LEDs installed so I can check the length. I'll resleeve these and put them on one three pin fan connector like I did for the reservoirs.
Under the brackets I’m putting some pieces of 1/8” Isolate It! Sorbothane Vibration Damping Sheets I found on Amazon. Using my paper hole punch to make the holes for the bolts. Also I put rubber washers between the fans and the mounting brackets that screw onto the fans. Now I have two layers of vibration dampening which I think will work great.
I spent at least nine hours polishing this top! Not all at one time though, I’d work on it for about an hour or so at a time. I’d put a Warriors game on the TV with a piece of glass and all my different grits of sand paper in front of me, and polish away. I ended up sanding right through the Bitspower branding too. I did not set out to remove the branding, but by the time I got the block sanded down enough, it was mostly gone, so I just went a little more to get it all off. I prefer it without the branding anyway so that was a plus. A big thank you to @lowfat

Here is the pump assembly mounted in place. I wanted the pump top to be at the correct height so that the input tubing will be perfectly horizontal and level. These brackets took much longer to make than I anticipated!
Here's some close ups out in the sun.
Here’s where I am going to ask everyone for your input. How should I finish these brackets off? I have some of the Cardinal paint that looks just like the CaseLabs black powder coating, right now I’m leaning to just painting them black.
However, since they are aluminum I could have them polished to a chrome like finish, or even have them chrome plated. What do you think?
Please post a reply with paint them, polish them or chrome plate them.
