View Full Version : I'm Sure Iwakis Die
I'm tired of hearing about Iwaki this and Iwaki that. Iwakis are not the end all and be all of pumps.
I am convinced that Iwakis routinely die, not that there are enough of you around to squawk about a dead Iwaki, or not that any of you would readily admit, not after paying what you pay lol
I am on a mission to find some dead Iwakis. How's that for controversy :D

Im sure they do die. To be fair tho, no pump I've ever had has ever failed on me. I think I've been water cooling for about 7 years now. 2 Eheims, several Iwakis, 3 D4's and 2 18w DDC's and none have ever failed on me. If I were a betting man, Eheim's would outlast them all - Probably the most reliable pump.
Hey.. none of the Laings I have owned, and I have owned a few, have ever died.
I just want to see where people get off saying that Iwakis are indestructible.

More than happy to use an Iwaki and let you know whan and if it dies as long as your paying for it Iany :-P
I have only had one pump fail on me in ~5 years of watercoolig it was a Hydor L30 lasted 4 1/2 years (as it ran 24/7 that works out a lil longer than its suggested 50000 hrs MTBF)

ah lolz, over here if ever it is found cannot be rebuilt... that pump would get gutted for copper parts for selling to junk shop real fast...
every part with motor mechanical parts eventually dies due to mechanical failure and friction and daily wear and tear.
we just hope that when it does, it will have accomplished its given task and that it would have earned(/profitted for some) its right to be replaced...

I'm sure some of failed. But then again, we might as well argue about about efficiency within our hobby and realize that all of this money is being spent with inefficient returns as is.
So, no need to point out that our investment may possibly not be all that worthwhile. I'm well aware that it isn't =). It's just simply fun.

I had a £20 fishtank pump pumping water about 6ft straight up which was on non-stop for about 7 years and that was like 10 years ago so it's not like the technology isnt available lol.
With pumps you get what you pay for tbh, any Iwakis that fail is going to be plain bad bad luck imo
I really appreciated the term used to describe Laing pumps.... "plastic junk." That's why.
I really love how water cooling has become such an elitist affair.. over some fish tank pump. First it was some silver water block, then it was some cube aluminum case. I guess all those have stopped being vogue.
Anyway, I'm being my usual provocative self :)

I'm not sure who called Laing pumps plastic junk, but they'd need to get their :banana::banana::banana::banana: straight. I only got the RD-30 because I figured it was the latest, greatest toy. If people are actually tying the size of their penis to the power of their pump, then they really need to get laid.
I might actually go back to the Laing DDC-2 w/ Petra's top instead of my RD-30. It all depends if I can fit the Meanwell into my system without it making it look like total @$$. Also if the pump is really that noisy, I might ditch it and go back to the DDC-2. It'd be nice to have a square inch of room in my system.

The majority of Iwaki's were designed to pump more viscous fluids than water and also to work in very nasty conditions, so odd's are they will have a long and easy life pumping water round a loop at relatively cool temperatures however everything dies at some point.....
man this is starting to sound like a video card thread :ROTF:

Hey... I'm probably the only guy on earth that's tried four DDC+ in series... and I can't get laid anymore because the "pump" has died j/k lol Should have gotten an Iwaki ! Need some Levitra or Cialis lol

Years ago when I had a 55 gallon salt water fish tank I bought a pump that was called "The quiet one". I forget who made it, all ceramic inside.
Dead quiet and the day I bought it the guy placed it in my hand and plugged it in. Could barely feel the vibration and there was no sound from it at all.
Use it for 4 years with a wet dry filter system.
I do remember that it was app $75.00 back then when other pumps were selling for $40.00
This was maybe 1993.

I just think you have anger management issues. But have fun. If people want to rave about what new toys they have let them be. If they complain about it later on, just turn around and laugh. There will always be people with egos everywhere, including this place you can't change them. If you want to stop people from having so much ego, go start your own site no need to try so hard to put people down.

I'll stick with my 4 "plastic crap" pumps, and my aluminum mixed GTX. I'm not losing any sleep wondering if my pumps are dead or my loop is corroding.
As far as the Iwaki, if it's mechanical / electrical it will die eventually there is no doubt about it.

im fine with my mag 3 pump, my crappy masterkleer 7/16th tubing, mcw6002-64 and heatercore. for watercooling its all about looks these days, it actually pisses me off to no end when i see wcing budgets up in the 300's and 400's. with a little patience they could have easily found a used machII GT or something. its just kinda ludacris.

Even if you find a dead Iwaki, I am not sure it proves anything at all. Is it one in a thousand? A million? Why did it die, misuse or bad part? What is the MTBF on them?
It is no more elitist to want to go for the best and pay an "insurance premium" on the pump over some brands that may fail more often. I do agree though, that if someone starts that cr@p about "your rig sucks because you don't spend $5K USD on watercooling" or 'you're a n00b because you use EK v. Swiftech blocks..." then everyone should call BS on it. The liquid nitrogen guys pwn all of us liquid coolers anyway, so it is just a matter of your own balance.

lol guess I'm a potential victim of that, I got masterkleer :p: Seems like decent tubing to me, though I don't have any tygon to compare it with it sure seems to flex nicely without kinking badly. It is also almost crystal clear too :D

Thats a newer version of it. But i think the IWAKI MD-70 is greater. Thats why i changed it out.
i had one too. Then i swaped it out to a iwaki md-70 for my 65 gallon reef.
that was 3 yrs ago, and its still going strong on a uv filter, wet dry setup. Oh i also have it hooked up to a squid wave maker. :D
Cant complain. There really excellent pumps iany. Thats why i decided to drop one in my computer. I had such great luck with there MD series in salt water, i cant picture the RD failing in a micro sub 1 gallon loop.

They suck, and they die. Oh yeah, and they SUCK.
Now back on topic, of course you're going to find a dead or dieing Iwaki here and there. Anything with moving parts is a prime candidate for mechanical failure because of a poorly manufactured/defected (DOA) part.
So yes, you'll find a few that die, just because they're most likely screwed up from the factory or damaged in shipping. Regardless of that, I doubt one is going to die in normal operating conditions.
Doesn't change my point that Iwakis do die. Having redundancy on a DDC+far far far more reliable than not having redundancy on an Iwaki. Don't get me started on the "make your own power cable and relay" thing for the Meanwell. The Meanwell itself isn't the world's foremost icon of quality and reliability.
H3ll, I may try RD30s, but not without putting them in series.

If laning spent a few more penies on the circuit board side of the pump It would be reliable(without loosing performance) the plastic housing does its job just fine (except for the mac ones with volume compensators :p: )

"High levels of durability and reliability
Manufactured to heavy-duty specifications for process use, these magnetic drive pumps can endure continuous operation over a long time under demanding conditions. The main structural materials of the pump are reinforced with metal to improve mechanical strength.
Strong corrosion and heat resistance
These pumps are manufactured mainly from fluororesin and SiC. Three standard types of fluororesins are used: ETFE and PFA. Especially, the PFA type allows high-temperature liquids (up to 120 C deg.) to be handled. EL-grade chemicals can also be handled.
Useful even in petrochemical plants
The casing cover of these pumps is constructed with FCD (ductile cast iron). Therefore, these pumps can be used in petrochemical plants where conventional resin-constructed pumps could not be used."

They suck, and they die. Oh yeah, and they SUCK.
They are powerful little pumps, so they don't really suck in that regard.
So what in your opinion is the best buy for someone like me who doesn't have a couple hundred to spend on a pump! Not sure on all the specs and prices of the iwakis but from what I've gathered they tend to be pricier, bulkier, noisier, have higher heat dump, or any combination of those.
Why don't they make some nice smaller quiet powerful 12V pumps in the pricerange of the DDC :rolleyes:
