Dude you are being trolled so.hard this.is a gas powered 5.5 hp pump, just tell.us more about your loop so we can help you

i got a better one:
Hayward Pro-Series S244T 24-Inch Top-Mount Sand Filter with 1-1/2-Inch Vari-Flo Valve for In-ground Pools

all joking aside i hear that the laing D5 is a pretty good pump, but im not sure that it is the best

the "best" pump made for water cooling, or at least most successfully used for water cooling http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_201&products_id=26144
you're going to need a 24 volt power source

Split it into three separate loops with three D5 pumps with custom top/reservoirs.

yea the problem with using one really powerful pump is sometimes they can output more pressure than the blocks can handle, since they only test the blocks to 2-1.5 bar or 29-21.75psi, meaning if you exceed those pressure you are getting into the territory what you might pop an o-ring and start a leak, at that point with split the loop or put a 2-3 pumps throughout the loop and only one would need a res for the loop to bleed decently, problem is don't turn on the other pumps till they have water in them

Run the loop in parallel, so that you can use 3 pumps but spread out the pressure. I would say either 2-3 D5 pumps or an MCP35X2 dual-pump would net you around 1GPM. The DDC is a MUCH better choice for such a restrictive loop than the D5 would be, I am 100% confident of that. The more directions you can spread flow at the same time, the better; i.e. Res - dual-pumps (split) - rad1/rad2 - block1/block2 - block3/block4 - rad3/rad4 - block5/6 - block7/8 - block9(one loop only here) - then have them join at rad5 if it is a Multiport design, otherwise one loop will get an extra rad. It doesn't really matter though, since there is only one reservoir shared by all components (may I suggest getting a very large reservoir?) which then goes on to feed both pumps. No pressure problems, and while each pump has "its own loop", it is not a true split loop. The advantage here is that ALL of the water will hit ALL of the rads so overall temps are likely to be lower, and having twice the amount of water means it will take a bit longer to heat.

Personally, I would organize the loop so that you have a total of 3 pumps: an MCP35X2 for one section and a single MCP35X for the other. The dual pumps should have all the major components in their section (say, CPU + 4x GPUs) along with 3 of the 5 rads. Then, the single pump should have the more-restrictive blocks (say, MB block + 2x RAM blocks and damn son how do you get TEN BLOCKS in one loop? Dual-CPU board with 3 RAM blocks and essentially 2x MB blocks?) along with 2 rads, ideally the 2 least-restrictive.
This will keep the primary components cool, and with 3 rads will allow you to slow heat buildup in between components, while the second section deals with the ridiculously high restriction blocks and flows slowly as a result but it doesn't impact the important section (CPU/GPUs). Since the reservoir is shared, everything stays the same temp (and even 3x RAM blocks covering 4-6x sticks each is only adding what, 30W?).

Just GET THE HEATSINKS FOR THE PUMPS! AND THE 80X15MM FANS!
