Can 2 pumps be placed in series back to back ...and two of those sets of series pumps be placed parallel to give double flow to a double head loop? In essence you would have 4 pumps total in the loop.

Someone is talking about doing this in another forum with a sketch included.

Dave · 05-16-2005, 05:42 AM

You can place as many in series as you wish, all I am saying is each pump add's less head, there is a limit to how much head pumps in series will produce.

4 Mags?
Why don't they just try one, then two and observe temps?

If you want that much head / flow, there are much better pumps out there for this range. Two of the new D5's will do well.

I think there wasting there money, but if you want to spend that much for an extra 0.5Deg C, go ahead.

Would be cheaper to buy an air conditioner and sit it next too your Rad

(Keep you cool in summer as well)

Edward Ng · 05-16-2005, 05:48 AM

Seems to me like a matter of trying to get massive flow with minimal acoustics, ignoring the price : performance ratio.

LOL ...I think the heat dump/noise was his main issue with other pumps for that price/performance.

Breach · 05-16-2005, 07:35 PM

New question-

How do these pumps handle operating without liquid in them?

I know with the fluid suspended impeller design like the Hydor L20 dont fair so well, and I know this because I had a slight accident which resulted in my L20 running with nothing in it for about a half hour straight, from then on it rattled, and looking at the impeller the magnet core was chewed up pretty bad as well. Obvioulsy the mag doesnt follow the same design, but I am just curious if these can be irreperably damaged by running without any liquid flow.

You guys suppose this might be a good sticky? Seems to be the CSP-Mag/C-Systems thread of choice

BRiT · 05-16-2005, 10:47 PM

Dave,

Can you estimate what the head and flow rate would be with the following setup, 4 total pumps consisting of 2 sets (of 2 in series) in parrallel ?

Code:

             ,,,, Pump 1 + Pump 2 ,,,,
Reservoir --<                         >-- Radiator -- 
             '''' Pump 3 + Pump 4 ''''

Thanks,

floflooo · 05-17-2005, 02:40 AM

Approx. slighty less than twice the head and twice the flowrate

I would do it today, but upper management types all away for some big meeting, and I need to ask first.

I just full of bad news today, should go home a sleep this bad day off before something else happens!

So, did the management peeps approved sending pumps to reviewers? I would like to see how this pump go against the other in the market today.

Dave · 05-17-2005, 05:54 AM

Not sure Brit, depends on back pressure.

Der- Some Mags run fine without fluid, some have high end vibration, depends on final balance. The fluid stops this vibration, hence "fluid stabilized" comment.

Running MAG open for short time is fine, long term can causes bearings to crack.
It is best to not run dry, if possible. I did run a MAG for over a week dry, didn't know the damn thing was on.

I sent the address to sales for the review pumps.
All the sales staff was away last week, for training. There are new customs rules and procedures for US shipments now. I am no longer to ship direct anymore, but will ask what went out.

Off to work, later all

ferdb · 05-17-2005, 09:06 AM

I have two gorked 750 MKIIs I want to upgrade, but on visiting the C-Systems website I'm given the option of Top inlet or Rear inlet designs. However the pictures for both are identical and I can't tell for certain from anything else on the website which is which and what the geometry of the two different versions really is. It also seems the MAG pump pages are cut and past inserts into the old 750 pages and that some of the stuff on there has nothing to do with the Mag pumps.
Somebody needs to go through and edit your site and bring it up to date.
Hoping for clarity.

Or C-Systems mistake??? CSP-MAG-R ???

Dave, could you please to light this doubt.
And, please, ask Julie to change C-Systems page picture (are both T and R same)...

Dave · 05-21-2005, 12:20 PM

^ Thats is just a customs label, does'nt matter if R or T, same price.

Or are you suggesting you ordered an R, and got a T model?

Let me know if someone made a mistake.

Dave

The model i have is ok, but i just want to know if mine is R or T.
Notice that C-Systems' homepage pictures are identical.
I'm suggesting to make it clear with true pictures.

Editing: some in Brazil are asking me about which is better T or R, asking me for testing my unit and how they could be sure about right model, since both pictures are same, at C-Systems' site.

Ok, if here it is impossible to get simple answer (like THIS is T, and THIS is R) i will contact C-Systems directly.

Thanks, anyway...

gazorp · 05-27-2005, 01:41 AM

When will my pumps be here dave? It feels like i have been waiting for ages!

Dick Dastardly · 06-01-2005, 06:41 AM

Hi all!

1st post at this forum, although i'm a regular visitor!

Dave:

I ordered 2 mags a week ago, directly to c-systems, and sent a mail to sales. I asked for an eta and about an issue in the site that didn't allowed me to order an hard mount for the pumps. Still had no answer...

I also need an opinion:

I have a loop composed of: 1 cpu block, 1 NB block, 1 graphics block, 1 dual hdd block, 1 black ice pro and 1 plack ice extremeII. I use 10/8mm tube. Should i run the pumps in series or in paralel?

Dave · 06-01-2005, 06:51 AM

^First guys, if you don't hear from sales, please just email again.

They have had several reports of email not getting through, and have discussed this with our ISP.

I have nothing to do with sales, and do not have access to there database, I am just an engineer.

Dick I would run in two seperate loops, both meeting at reserve.
Too date this has been the most effective configuration.

Running one loop at high pressure / flow will not be as effective as two loops at lower pressure / flow.

I would also suggest, given all that plumbing, you cosider one of the non-conductive fluids, as your chances of leaks are higher then average system.

Post some pic's when your done!

I liked the two loops idea. I just need an extra opinion on the loops: I'm thinking of having one loop with the CPU and the BI Pro and the other BI Extreme II with the NB, Graphics and the HDDs. What do you think?

My specs:

P4 3.0 (prescott)
Asus P4P800E (intel 865pe)
Geforce 6800GT

oh ...I see fluid xp+ magnum getting into the act!

Dave · 06-03-2005, 06:55 AM

^ That is a interesting version, about 20% more torque then standard MAG.
Low RPM and impeller is designed just for XP as well.

Not sure why there using an head unit picture, so far I have only seen XP pumps at the shops.

kaotic504 · 06-04-2005, 04:40 PM

Dave, the XP Magnum pump is only $5 more than the regular MAG pumps. do you really believe it performs better? also, right now DTek only sells rear inlet MAG's i believe, i believe the "T" stands for Top inlet and the "R" stands for Rear inlet on your site, is there a performance increase running it w/ a Top inlet as the DDC's benefit greatly from having a Top inlet. also, do you think at any time in the near future, C-Systems would well just the tops, so that the users may convert Rear inlet pumps, to top inlets and vice versa? thanks! there are so many products are the market now, it's getting very difficult to decide.

I imagine the higher torque would be to make up the difference of the lower vioscosity of the fluidxp ...I suppose.

Dave · 06-05-2005, 07:46 AM

The XP model is designed just for fluid XP.
XP has a higher viscosity then water, and like using too much glycol, it will void warranty.

This is a long term load issue, where our electrical components exceed our certified test conditions.

We modified the components on the XP model too provide the proper loading with higher viscosity of XP, or glycol mix of up too 30%.

If you use water, or low glycol % mix, standard MAG will work better for you.
