Dual Pumps in parrelel?

[Pricey]

I'm looking around for pumps in auzzie (mag 3), but I came across the Waterwerks Accent. They sell in bunnings for around $35 (yes i know its damn cheap). It has a head of 1.4m and 1000lph. I realise that a large head (not litteraly) is required in a WC loop so, If I run the pumps like this.....


Would it better a Eheim 1250 or run pretty decent.
BTW I'm getting a Cheiftech Dragon Full Server case so I dont think space will be an issue.

How do you think it will go?

If you want more head (which you do) you should run them in series not parrallel

Righto,
What do you think of the pumps?
Would it be better to save and get a Mag3?

Cheers,

i'm afraid Mag3's only come in 115V/60hz

you could keep your eyes peeled for an iwaki on ebay...

this is probably the best place to get Oz-specific pump advice

Two pumps in series? hmm. I am no pump expert but that seems like it would provide little benifit. Would they go in one after another or one placed further down the loop? Just curious about this.

Attualy it provides quite a bit of benifit flow wise. Placing the pumps in series is like having a pump with a bigger head pressure but the same flow rating. As you may well know the head rating (or pressure rating) is much more important in watercooling as the loops are very restrictive. The down side is that more heat is dumped into the water so it countereacts alot of the benifits of higher flow.

Yeah, and the other advantage is should on pump fail, the odds are that only on will fail at the same time, so the setup won't be pumpless, kind of like a redundancy safety feature.
