The existence of this thread seems to indicate otherwise:

Here's a link to the build

If there is two routes, and each route will go through only one pump, that is parallel. Most common advice I have read is that the order of the loop makes little difference, as long as the reservoir is feeding the pump. If you have two pumps, only the pump you will run while filling your loop really needs it.
My opinion. I have no data myself to support, but all that I have read, including at Martin's and Skinnee's site, support this statement.

Thanks guys. The specific question was indeed weather i should put the 2nd pump near the "end" of the loop as a "return pump", or in a "series" one after the other. I did end up placing it after my second of 3 radiators, Very close to a "series" one after the other.

I figured it would be a good spot. The first rad is a TFC 240mm which is very thick and holds a lot of water. second is a swiftech triple. After those 2 is a hardware labs 120 stealth, which is the more "restrictive" of the bunch. As well as having a large amount of bitspower 90's.

I was a little heat soaked after a little while and the very low flow of water returning to the res. gave me the thought of a flow problem.

The 2nd pump did actually help a good amount. running it on level 3 brought temps on all components down an average of 5c.
