Iwaki Rd-20 / Rd-30 Pricing: Ordering Now Closed

[fareastgq]

Ok guys, PM me please if you want a rd-20 OR rd-30, I'm not going to post prices here, we are getting them for sure, I've got about 10 people now, we are getting half of each pump. Hint, they are cheaper than what I thought they would be ( prob due to our quantity buy). I'll wait 2 days and only 2 days for you to pm me, I'll be ordering for the group on Friday, we should get our pumps by Wed or so, and everyone that ordered should get them by Friday or monday of next week ie: around tax deadline time . This is what you will need to do if you want one. PM me ppl don't miss out on the best of the best period.

-You will pre-pay for your pump (yes the rd-20 is cheaper than the rd-30)
- You will send payments to jeepryder@yahoo.com
- I do NOT know how much shipping is so you will just pre-pay for the the pump, I'll let you know how much you owe for ship when I actually have them, expect $7-$15 for shipping, these suckers are heavy.
- Everyone will pay cost+ shipping, that's it. this forum rocks and so do you guys, so... enuff said.
- Please EMAIL me at fareastgq@hotmail.com and title your email with whatever pump you want. (this forum has been flakey lately and I want a good way to contact you)
- Yes, you do get the manufacturer warranty with this buy so no worries
- PM me for details

Thanks for helping out the members fareast!

If anyone trys hassling you about "sellling outside of the classified" just lmk.

NO SELLING OUTSIDE THE CLASSIFIEDS!!$@$#@ ROAR!!!!!!!!!!!!

PM me the price for an RD-30 please

[creidiki]

Could you PM me the price of both with shipping to the UK?

And a link to the specs so i can see if i can fit them in my case? Thnx ^^

[nikhsub1]

Jeez, google? http://iwakiwalchem.com/default.aspx?tabid=21&menuid=23

[creidiki]

Google no workie here. @ my moms and the dns is about as funny as watching mtv's "life of britney spears". Im only able to access this site because of dns cache on my lappie.

This looks like a good step-up for an RD-30: http://www.meanwell.com/search/SD-50/default.htm

Did a heat-dump test on the RD-30. It's heat dump into the loop is actually fairly high, despite being a magnetic armature design. This is supported in that the casing barely gets warm.

Basically measured that around 83% of the pump's power draw gets passed into the water during in-line use.

Pump was measured to draw 28.1W. Calculated heat dump was 23.2W, with around an estimated 10% margin of error on that value.

Plugging that back in to the maths of the first two posts, this works out to:

+20.7C => Iwaki RD-30 @ 18.0v
+20.8C => 2 x Swiftech MCP600 @ 13.8v (series)
+20.9C => Swiftech MCP600 @ 13.8v
+21.1C => Iwaki MD-20RZ @ 60Hz
+21.1C => 2 x Swiftech MCP600 @ 12.0v (series)
+21.2C => Iwaki MD-20RZ @ 50Hz
+21.4C => Swiftech MCP600 @ 12.0v
+21.4C => 2 x Eheim 1048 (series)
+21.5C => Iwaki MD-15R @ 60Hz
+21.6C => Swiftech MCP650 @ 12.0v
+21.6C => Iwaki MD-30RZ @ 50Hz
+21.7C => Iwaki MD-30RZ @ 60Hz
+21.9C => Eheim 1250
+22.3C => Eheim 1048
+23.3C => Eheim 1046

PM price for both (deciding which) - shipping inc. to uk please!

Edit: Im thinking that the heat dump on these might be too much for a pa160? then again flow would be good for a g5 and mp-1 which are both restrictive...

[creidiki]

Right... thats @ 18v though. I wonder how it woudl perform at 23-24v?

[fareastgq]

ok guys, all pm's send and replied to, I WILL ship international anywhere BTW for those of you who want one international, again, I have no idea what ship will be, it's $7-$25 most likely depending on where in the world you are. So don't be shy about international buys. Btw, they won't get cheaper than that unless we order 100 of them, I don't think we have enuff ppl for that, I am up to 18 though, heh. find 80 more and we'll get an even better deal, hahaha.

[MaxxxRacer]

wow... 18.. im shocked.

Shame im not working right now or I would be ordering one of these magnificent pumps.

That is good sound, I think will take a RD-30

[situman]

THese pumps are not good performers at 12volts right? I might have missed it, but how does it perform with a regular PSU?

whoa, youre saying that the RD30 only has 23 watts of heat dump?

thats really good!

[Danger30Q]

I'm torn between the RD-20 and RD-30. I know I'll be undervolting both pumps regardless with either a DC-DC converter with variable voltage control or getting a Mean Well 24V PSU to plop inside the case.

I really don't think any of us need the extra power of the RD-30 considering it's increased heat dump. Unless you have 5 triple radiators, I don't really see the RD-30 worth it. However, the idea of having more power is always intriguing so I still don't know what to do.

Regardless of the pump you choose, you are likely getting massive pumping overkill.

[nikhsub1]

They will not run much below 16-17v or so.

base on that article from Cathar...yup, heat dump is not too bad at all considering it has very high head and flow rate, but the big question is....DO YOU NEED IT?? Cathar's investigation is quite interesting, check out his thread "How much pump is enough, How much is too much?"

What I would really like to know, is the heat dump comparison between the RD20 and RD30, if the difference is only within 3W then I'd say RD30 is a better deal, only $15 more but has much higher flow rate, both units are exactly the same size (base on iwaki specification and from what I was told), you'll need a DC-DC converter anyway so if you don't need all that extra flow rate then crank it down to ~18VDC. I'm still trying to justify spending a grand total of $300 (pump + converter) for merely 2'C (from what I've read) of improvement over the Swiftech MCP655 pump that I've got, and overclocking wise what does that 2'C going to net me decision decision.....

if you manage to get 79 other s to buy ill take one! im broke, but ill take one then!

[Danger30Q]

You make a good point Ben. I really don't think I can justify spending almost $300 when I could get the Iwaki MD20RLZ. However, I'm intrigued by the much smaller size and quieter operation. I also must say I can't stand the ugly blue of the MD20RLZ. I also want the absolute best I can find since I will likely be able to use the pump for at least 3 years and not have it get mopped on the floor by a newer pump.

I still really don't know which of the 2 to choose. It would be great to see everyone post a pic of their new system with these pumps and flood the forums with RD20/30's!

i think this has more to do with the bling factor of the pump more than it does the performance. if you make something harder to get more people are going to want it

If you can't afford a meanwell, your psu will do fine. (uh assuming it's name is zippy 700, PCP&C 510/850/1000, ocz 600w+ and such). I wouldn't go with anything cheap to run those 2 pumps. I'm running mine at 21v off my zippy 700, it's fine. 12v DC to 24v DC variable converter. You know in the back of your head you want an rd-30 because this is Xtremesystems... wtf is overkill?....hahahha.

[skaktuss]

wtf is overkill?....hahahha.

yeah, i think so! $/°C ratio is not very good! and considering that money i'd better go for a phase change cooling!

Is this the correct converter to get for the rd-20?

What size fittings are on the rd-20?
