So....insanely powerful pumps?

[JoT]

I'm looking to get something on the scale of an Iwaki, cost isn't exactly an issue at the moment.

I just don't know what to get; I dunno if getting a pump that's too powerful would blow the hoses off the barbs or what :eek:

I saw someone post about their T1, which looks beautiful, but I went to where they bought it (here (http://www.marinedepot.com/a_pu_csl.asp)) and I see the T2 is the exact same cost as the T1.

I checked out some Iwakis here (http://www.marineandreef.com/shoppro/CA_Iwaki_Pump.html) and have not a clue what to get get, all I know is more head = better pump. And I know the Iwakis have a really good reputation.

I'm going to be running a cpu block, chipset, video block, chevette heatercore, and perhaps one or two other things. Since I'm still new to water-cooling, I really don't know where to go with the pump. Suggestions?

The Iwaki 20 MDRZ (I think...something like that) would probably be the best Iwaki to get. Anything higher than that has a tendency to dump more heat into the water than the increased flowrate can compensate for. T1 would probably also be a good option, but without as much of a reputation.

You don't need to worry about blowing hoses off or anything, pressure won't get so high that anything like that would happen. The main thing you need to find is the balance between pump heat and flowrate. With a larger (and warmer) pump, you might want to look into getting additional radiators to compensate.

[SewerBeing]

if you really want an awesome system, get a T4 and an additional radiator to compensate for the heat.

Based on bang/buck ratio, there's two pumps:

The T3: http://www.marinedepot.com/md_viewItem.asp?idproduct=CL7115

The Iwaki MD20RLT: http://www.marinedepot.com/md_viewItem.asp?idproduct=IK1123

Both end up being ~$170. I wouldn't know how much extra heat the T3 dumps into the water than the T1, but it couldn't be THAT much, could it?

Holy crap, I may not even be able to try to get any of the the T pumps!

Well about the highest I'd go on pressure would be around the 26PSI mark, or about 18mH2O, or about 60' of pressure head.

Anything higher and you risk your heater-core springing a leak, unless you stick it after the waterblock.

In terms of pump "insanity", even an Iwaki MD70-RZ would only just take you the point of heater-core bursting pressures.

The Velocity T1, which I guess is a bit like a cross (in terms of performance) between an Iwaki MD20-RZ's pressure and an Iwaki MD-30R's flow, would be at the extreme upper edge of pumps that one would want to use. The T2 is a worse choice than the T1. The T3 is a slightly stronger choice than the T1 in terms of power where you want it, but pump heat will be a predominant factor in your setup.

The Iwaki MD30-RZ would typically yield higher real-world flow rates than either the T1 or T3 though, and has a power consumption close to a T1.

I dunno - if you're looking at a T1 or T3, then the 30RZ would be the better choice, if better choice is something that can be attributed to pumps that strong.

The 30RZ will supply about 15PSI of pressure.

My mag 3 has blown the hoses right off my barbs, I had to tighten my hose clamps WAY down. if you got 2 and ran them in s series, you would have helapressure.

Ok, I think I've got what you're saying, so the MD30 or the 20 would be the best choices in going the Iwaki route? I'm designing this system around your White-Water block, Cathar :D
If I remember correctly, more flow through that block = increased performance, and that's one of the best blocks to have a lot of flow with.

Since it may not even be possible to get the T series now, I'll head for the Iwakis, and thus the MD30 or 20, depending on if I can get the funds *crosses fingers* things should go well.

i Would go with this pump :

#%&@! There goes my two year warranty :(.

The problem with thes heftier pumps is the heat that they put out. As johan said, you get into the range where the high flow and pressure cannot compensate for the heat being added to the water by the pump itself. Adding more/larger radiators is one way you could deal with it.

Of course, after getting my CSL T1, and playing with it a litte bit, a 10 foot bong cooler is a project that looks really fun, and irrisistable (cheap too).

This looks good to me. (http://www.marinedepot.com/md_viewItem.asp?idproduct=DP2300)

The Velocity pumps are actually rebadged Laing pumps.

I hope that CustomSeaLife makes some kind of arrangement with Laing to cover the warranty on the pumps.

Hmm, if I could find one of those red Laing pumps, that would be perfect; my case theme is red and black :D Thanks, Graystar

[felinusz]

Nuts, my case theme is red and black and orange :(.

My CSL T1 is blue :D LOL.

Seeing how much these pumps cost, I'm sure that the warranty will still be supported over in some manner. It would be a really sad ending to a well-thought of company such as CSL to close up shop, and leave all warranties for their many expensive 'reef-guy' products blowing in the wind.

Thanks for the info Graystar, now I know who to go to if my pump dies unexpectedly.

Googling for Laing pumps is turning up few sellers, and not really any decent ones. It seems as though Laing pumps are used primarily in spas, so the Laing site directs you to "contact your local spa dealer".

This (https://secure.webcoretech.com/backyardspas/category.cfm?Category=411) is the best site I've found so far, but I'll probably have to call to verify a color on the pump. Looking at this site, the Laing pump I'm after costs way more than either of the Iwakis. Crud. Looks like I might get an Iwaki and paint it red :-/

Edit: Found this pump (http://www.spadepot.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=SD2000&Product_Code=BX4200&Category_Code=pumps); looks to be the right price, and the site says that the older pumps were black, indicating that these should be red, but it doesn't state the power of the pump!
Edit2: Here (http://www.lainginc.com/norylsm909n14.htm) is Laing's page for that pump, but it STILL neglects to state the head and throughput >_<

[Bailey]

From the chart in your link that Laing pump looks to be about 420gph @ 0' (7gpmx60 = 420gph). ;)

The only think I can say is that in several years of aquarium stuff there's one brand of pump I've never heard a bad word about - Iwaki (especially the MD line).

You want a high quality & not too expensive pump? Take a look at these:

http://oceanencounter.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=OE&Product_Code=OR2P6G&Category_Code=OR

They are made by AquaMedic who has an excellent rep in the Aquarium world. I have one & it's a great pump. It's been running for over a year w/o a single problem (I've yet to even clean it - lol).

Here's the detailed specs from AquaMedic:
