Serial pumps

[grandpatzer]

I want to run 2 pumps in series a Laing DDC-1t and a Laing D5.
The purpose of this is 2 reasons:

1: Redundancy so that incase one pump dies the components won't fry.
2: Having 2-3rads and 4 blocks might need more than a D5 at low level.

Now I have read the Martins liquidlab article on running 2 pumps in series, english is not my first language so couple of questions:
My understanding is I can run the pumps at different speed aslong as I don't exceed the maximum flow limitations of the pumps no harm is done?

Basicaly I can safely run the Laing D5 at lowest speed which is Level 1, considering the Laing D5 is stronger then DDC-1t this means that the Laing DDC-1t even as it will be running harder then D5 because the D5 limit is not exceeded it won't take damage from the DDC1-t correct?

I would match pumps if running two in the same loop but yes, your logic would seem sound, the more powerful pump won't be damaged if the lower powered pump is running at maximum
Have you decided on rads/blocks then?

I'm really liking my 2 existing 240 + 360 rad and to that add either a Phobya 1080 or a Phobya 360.

I'm familiar with the set up, I see your going to keep the 1000w Psu
if theres little difference in price go for the 1080, you'll be crazy not to

Yeah there almost same price but I also need get QDC for the phhobya 1080, still I like the 1080rad as I think with the Quick disconnects it will be neat the maintain and move the case when needed.

Yes, external rads (as in away from the case) should always have Qdc's in my book, purely for convenience
And the extra radspace will never be a bad thing
