Wrong. Our pumps (centrifugal ones) are *not* volumetric, i.e. they dont work by moving a given volume of water at each engine turn (volumetric pumps are quite bigger, noisy and way more expensive).
They work by applying a pressure differential between outlet and inlet. The flow is only a product of this pressure differential minus the 'backpressure' of the circuit.
What that means is putting 2 different pumps in series will increase total head pressure, thus flow. Beware if your pumps are, say, 300 and 150gph the total flow will *NOT* be 450gph but i guess you've figured that already.
The 'lower' pump will only add its head pressure to the system.
Now as of putting them in series or parallel... i'd say series but tests need to be done on this (someone has experience on that matter ?)

I was about to make a nasty comment
But since it's MS paint you're excused.
