iwaki MD-15R or swiftech mcp600?
 

hi all

been thinking of getting the swiftech mcp600 cause i hear it rocks when it comes to pressure but i cant find any solid reviews on it at the moment therefore i thought maybe i should buy the iwaki MD 15R.

my question is would the iwaki perform better in a loop with 2 blocks and modified 11-1/2" x 6" heater core?

Re: iwaki MD-15R or swiftech mcp600?
 

Let's see. The MD-15R has a max head of 3.4M, 300GPM @ 0 head and consumes 30W. The MCP600 has a 2.2M head (at 12V) and flows i think 160GPH @ 0 head. I can tell you this, I do like the new Swiftech pump but the build quality of the Iwaki is second to none. If you even saw a 1C difference between the 2, I would be surprised even though the MD-15 will flow more, it also puts out more heat and is not plug and play like the Swifty. If I decide to liquid cool my NB and my vid card, I will be getting one of the MCP600 and running a totally seperate loop.

hi nik

hell yeah that's exactly what i have in mind for my rig (true dual loops). i was askin' cuz some are calling the mcp600 "industrial" so i am not sure which one to get.

one more thing where can i get the iwaki MD-15R, i can't find that model any where.

the initial curve that I put up was at 10V, and I did not know this
the one above is at 12V (3500 RPM)

the Iwaki is hardly a mainstream WCing pump, which is what Swiftech is attempting to make the MCP600
- both have a closed impeller ("Z" only on the Iwaki), sealed ball bearings, etc)
but the MCP600 is MUCH cooler (temp, color too - lol)

I can attest to the fact that the MCP600 does more volume than my Enhiem 1250 and as far as noise, the enhiem is only slightly quieter (Swifty hums a bit but you gotta have your ear within 1 foot to hear it at all.
These results are based on my obsevations only.
The Swifty throws water farther than the Enhiem and I am not the best judge of sound ( to many Crank it up contests)
Currently I have my 2 Swiftys up running for a couple hours now, and I dont hear them running anymore. The enhiem is still cooling my old setup and is running within 3 feet of the swiftys. That being said ( to my ears) the 2 swifty's are no louder than the single enhiem.
Oh and my inlets are facing up ( thanks for the Tip Billa).

I know, not very scientific, but Hey, I live in a swamp!!.
What did you expect? :D
Overall I am very happy with the Swifty's.

Edited for spelling, and its probably still WRONG!!!!

hi all

Aardil, real world observation can be a good form of judgment and it is welcomed by me.

now that the wifty pump is covered would anyone like to throw in a bone for the iwaki.

Right Les, I did not see the 'updated' P/Q chart. Originally Bill had the max head at 2.2M right? Or am i losing it? Now the #'s look MUCH better. Bill you were running the thing at 10V and didn't know? Hmmm...

With the above corrected P/Q chart, I can't see a reason not to go for the MCP600. It has about the same head as the MD-15R yet will run cooler and use a molex and will cost you about 1/2. Don't get me wrong, I love my Iwaki but if I were in the market for a pump today, the MCP600 is what I would get. I got lucky with my MD-15, I found it new on ebay and got it for $70 shipped. New they go for around $135 or so. Not worth the extra cost IMO.

hi all

nick, i just might get the mpc600, still not sure tho. if i find an iwaki cheap i'll buy one but i doubt that.

by the way your ss looks badass!

I want an MCP900.
Love this new pump, only need a litle bit more power.

Edit : NM

Thanks,

Bill,
possible problems of running it at, lets say, 15 volts?

15V ? YES, too high
13.5V max (4m of head !)

How would you go about getting more than 12V from the PSU? I like 4M of head a lot! Bill would you say 14V is max for the pump? Any data on lifespan and overvolting?

the pumps are RATED and WARRANTIED for 12V service - period

I have data at 13.5V (and 10 and 9.5V) but all such is at your risk
if the electronics fry don't bother asking for an RMA, eh ?

Okay, here is the whole problem with iwaki's ... their naming schemes confuse the hell out of everyone, including me at one point and thats why I held off on a purchase until I knew the exact specs.

MD15R is not enough info. There are R's, RX's and RZ's. R is standard, RX is high flow, and RZ is high pressure. Check the chart:

If you're in the US or canada, you're on the 60hz chart.

Ok the MCP600 cannot be run submersible.
But i wonder if it can be modded in such way so that it can?

It is actually quite easy, you have it right. The MD-15 only comes in the R, not RZ or RX. The hard part is figuring out the barb connectors. Sometimes "M" designates threads, yet sometimes it is "T". My MD-15R has fixed 1/2" barbs, no threads. I always thought that "T" meant threaded until someone got an MD-15RM which was threaded. Go figure.

Oh I'm aware its simple, kinda like a BMW naming scheme :D But it still takes some getting used to, and referring to a pump as an MD15R is not nearly sufficient. Its like calling an M3 a 3-series :D

I think "M" means 'metric threads'

and "T" means, 'threaded for those stubborn bastards who don't use metric'.

How could anyone find it confusing?
