Water Pumps - List yours.

[Seyeklopz]

I am curious what water pumps you guys are using. I've been searching the net for other types of pumps, but have found little. What do you think of these? I can't find information about their noise levels.

[jaydee]

Those Danners are good. They are kinda large though. You can get them at Home Depot and other places under different names.

I use one of these 500GPH HydroThrusters: http://www.aquaticeco.com/aquatic1v1...nfo4=0&eflag=0 in my testing setup.


I also have a Little Giant 170GPH Inline pond pump, a 200GPH submersible pump, and a 12VDC 500gph beilge pump for boats.

I've got a Little Giant 2-MDQ-SC, but I'm opting to use two Johnson pumps instead:

Neither of these are "normal" pumps though (they have thier advantages and disadvantages).

The popular choices are: Eheim (1048, 1250), Via, Danner, Maxijet, and even Rio, among a flock of others. Top of the line would be Iwaki.

The Eheims are the most expensive, out of the aquarium field, but run quiet and are very reliable. If you look into industrial products, you'll find a whole lot of units (like March), but you really only have to watch out for a couple of things:

1-Be aware if the pump is self priming or not. Some cannot be run dry, under any circumstances.

2-Be aware of the noise they make: centrifugal pumps are usually the best choice here.

3-Make sure that they are rated for continous use. Avoid bilge pumps.

4- Understand that pumps are spec'ed with a max head, and a max flow rating, which are two seperate things.

5-Be aware how these must be mounted: some centrifugal pumps do not like to be mounted with the motor down.

6-Mke sure that you know what the connections are. The Johnson pump has 3/4" barbs. My Little Giant has 1/2" NPT threads.


Once you've selected a pump, go over pHaestus' article, and find the part about inlet pressure (a link to a PDF, I believe), and note how the inlet should be set up.

Good luck!

From a price/performance/reliability standpoint I would say go with the Danner Mag. They are awesome little pumps. The 2 or 3 series would suit most peoples needs and are very quiet. I had a 2 running for several months and I couldn't hear it from 2 feet away but it did make a slight hum if you put your ear up to it. I only took it out because I got an Iwaki. I would get a 2 for a single block setup and a 3 for multiple blocks.

[Seyeklopz]

Are the Iwaki much quieter than the Danner? What do you like more about the Iwaki? They seem rather large, we're talking about the greenish colored pump with a white plastic chamber right?

Which pump model would you recommend if I had a cpu, gpu, chipset, and 3 hard drive blocks

[Asmordean]

Laguna Statuary 3

It has been pumping for almost 7 months and is pretty quiet. I replaced my ViaAqua 1300 with it. That was a hot / noisy little sucker.

It isn't ment for inline use.

[Razor6]

I use a Danner mag 5. I would have bought the mag 3 but when I saw the price difference was only like $6 for an additional 150gph I said what the hell and got the mag 5.

I would say that for the money they are quite good. The only thing that can be annoying is a slight clattering noise that comes from the magnet riding on the shaft. Danner gave the magnet some free rotation so potential pump jamming material could pass through, which isn't a problem for watercooling applications. I should glue the magnet and shaft together but I'm too lazy.

[jovetata]

i also have a danner mag 5, i got it from work, nice and cheap (of the five finger kind)
and i have a aqua clear cap 1800.

i got these two pumps to see which was better. in reading the specs, the danner puts out 45 watts of heat, the 1800 puts out 29 watts.

danner 5 puts 500 gph and the 1800 628 both at 0 head.

danner 250 at 5 feet and 1800 315.

so unless the 1800 is unberably loud, ill have to go with it.

BTW just waiting on a block to set up my water cooling rig

[romebaby]

I have the Iwaki MD-20R and it is louder than the Danner. The Iwaki has kind of a high pitched whir vs. the low hum of the Danner. I can hear the Iwaki sitting in my chair whereas I couldn't hear the Danner at all. I only got the Iwaki because I'm going to be running some geothermal cooling here in the near future, either an underground tank or a maze of tubing, and I needed the extra head of the Iwaki. You can tell the Iwaki means business when it starts up.

I was running a Mag2 with 3 blocks(Swiftech mcw5000, mcw50-t, and the dangerden z chip, all pretty unrestrictive) through a Dtek heatercore and about 40 feet of tubing including a 20 ft copper coil submersed in a 5 gallon bucket and it pumped great. You can take a look at it here if you want. I tried a Mag 5 also and saw no temp difference but the Mag 5 was louder. I think the increase in flow was negated by the increase in wattage of the pump.

If you look at the charts on the Danner 3 and 5 (on the link you provided) you'll see that the 5 starts out better at 0 head but they even out pretty quickly. At 6' of head they both push 180 gph and deadhead at 10.5 ft. I think your best bet is the Mag 3, to keep the wattage down. Or if you have the cash, and/or have restictive blocks, the Iwaki MD-15 or 20R. I picked up mine on ebay for $84 in excellent condition but they run about 150 new. BTW, you're going to need a good sized rad with all those blocks!

Answered by romebaby (Welcome!). That's the green/white one all right. I've never heard of noise being an issue: maybe this is an isolated case.

Here's another pump roundup I started, a while back:
http://forums.procooling.com/vbb/sho...&threadid=3650

[romebaby]

Thanks Bigben, actually the noise from the Iwaki is not an issue. He asked if it was quieter than my Danner2, which it is not, but it is not that loud. If I had any of my fans higher than 5v I probably wouldn't be able to hear it. Actually it is kind of nice to be able to hear it, with the Danner I had to put my hand on it occassionaly to make sure it was on.

I've been running the Iwaki MD-15R for about 6 months now. This is a smaller version of the MD-20RLT, 300GPH @ 0 head with a max head of 3.4M (11.1 feet i think). Iwakis do mean business, you can tell when you turn it on as Rome said. I had a 20R but it was too big for my case. The great thing about the 15R is it only consumes 30W of power, just a tad more than the 1250 but has nearly twice the head. Iwaki's get VERY hot on the casing, like burn your hand hot so beware of that. They are very good at not transferring much heat to the water though. I have a new project I am starting, all the pieces are on their way to me. When I do that, I may end up with the MD-20RZT as I will be running multiple rads in this one. Wait till you see this beast.

And I think the best head/watt ratio in the Danner pumps is with the MD3.

[JokerCPoC]

I have a ViaAqua 480 (200 GPH), But It needs to be modified first, As Its inlet is meant to be submerged, The Outlet is ok and I have the parts to adapt It and the GE Aquarium Silicon adhesive. The GE stuff will adhere to glass and/or plastic, As that's what an Aquarium is made of most of the time. I only have the Gemini Cool rev. 2 cpu water block, I still need the water blocks for the NB, SB and GF4, that and a Relay kit for the Pump, Then to top It off a Window kit and two UV Cold Cathode Lights for My New Black case.
Danger Den, Gemini Cool is just as good, But I can get these parts for $19.95ea. Kyle over at the HardOCP had a comparison of 15 different blocks and Gemini Cool was in the Top 5 along with Danger Den.

And everyone here just laughed at that review...

I've got an Iwaki WMD-20RLZT, 174GPM and 22.6ft head rating. I know, it's the American model, but that's what I've got and I like it =] It makes a bit of noise, but certainly less than my 80MM Tornado, so I'm happy with it.

I have a few pumps at the moment:

Hydor L20
Eheim 1048
Hydrothruster 500gph (thanks Joe)
Little Giant 3E-12NYS
Hydor L30
Laguna stautary model 3 converted to inline use.

In the past I have used a Danner 250gph and an Eheim 1250, but they are no longer in my possession. All have been fine pumps in their own right, tho I would never use the 3E-12NYS in a normal system.

Have you done anything with it yet?

So I take It You have a Low opinion of the Gemini Cool water blocks?
I thought that for $24 for the the Socket A Water Block I couldn't go wrong, the other 3 blocks & a Relay kit will cost Me $20 each., But then I've a budget to maintain and cool My Athlon XP 1.84Ghz (see sig for stock speed) cpu and It will go higher too at least to 1910Mhz, Not like some expensive Intel P4 cpus that are Multiplier Locked by Intel. Mines all in the Bios, Stock Multiplier/FrontSideBus is 11.5x133Mhz-FSB.

Well at least the ViaAqua 480 is ultra compact, has a ceramic shaft(that's what the box said) and pumps 200GPH and only cost Me $15.00 on ebay.... :shrug:

And as to Multiple Rads, I'll be running one MaxXxpert Rad, Although I'll have the room to add a second one to the mix If I really want at anytime I have the extra cash on hand.

No, no.. he was refering to the review itself not the blocks. BillA reviewed the Gemini blocks and they work pretty good. Certainly not a bad choice, especially for the price you found it at!

[JokerCPoC]

Ok, Thanks for clearing that up. The HardOCP found this Review and had It translated, I tried both Google and Altavista and Neither would touch It for some reason, while this Translation paralink does, weird, very weird.....:shrug:
Main Review page
This block looks like the Gemini Cool series, Talk about errie..

No I was not referring to the block itself like Jaydee said, it was the review.

Of course that's If a Second rad would fit under the first, Without resorting to a Thermaltake "elbow" or something... I plan on using an 80mm to 120mm adapter to hook the MaxXxpert up to the 80mm opening and using either a 80x25 fan (SF2) or a "Hairy Howler" 80x38 tornado and possibly a 120mm on the other end with 1 or 2 (3/4" thick each) Danger Den Fan Shrouds (120mm spacers for those in Europe, Shrouds is what They are and Fans are not Shrouds here in the USA). I may have to attach the 80mm fans outside the case, that and cut away the grills there too. My cpu (104F) is 13F warmer than My 8RDA+ r1.1 Motherboard and I do believe the Temp outside My house is a Nice 105F Today, Yumm, Toasty.....

[SCompRacer]

Eheim 1046
Eheim 1250
Via Aqua 1300 (Quiet with no mods)
Swiftech MCP300 (Silent with mods)

What kind of impeller shaft setup is used in the Hydor L30's? Is it like the Eheim and Via Aqua where the shaft goes all the way through the impeller and is supported on both ends, or does the impeller have a blind hole sitting on a fixed shaft anchored in the pump body like the Swiftech MCP300?

[JokerCPoC]

I looked in My ViaAqua 480 and It's shaft goes all the way, But It looks like once I seal It up with Silicon Adhesive, that will be that. And It should look like this one, I found It on ebay of course. And no I didn't buy It as I'm currently broke.

[airspirit]

The hum from the danners is from case vibration. If you put it on rubber/foam mounts then it will not cause that hum. I had both a 500GPH and 350GPH and they were silent if mounted correctly. If not, though, the hum was annoying.

I currently have a GenX 1100 GPH or so pump that makes a frickin racket, but it pumps an ungodly amount of water at high heads. It also has a built in 80mm or so fan for cooling
