20RZT best pump for me? Any other choices?
 
After reading Cathar's pump article Ive been looking for a 20RZ ever since.

Im trying to get a pump for a large setup Im building which consists of:
5' hydronic heater element (ID of the pipe os 1.3" and one pass so low pressure drop) and 5 waterblocks. two mcw6002s, maze4 gpu and nb, and a VRM block that will be just 1/2" ID copper pipe and two 90 degree copper fittings.
The radiator will obviously be external. About 10' of tubing from the pump to the box each way.

The 20RZT wont be too weak, would it? Im having a heck of a time trying to find one, so if I did and bought it and found out it was too weak Id cry like a little school girl. Found one on ebay but the guy said it had toxic medical dye pumped through it so I passed on it. Second one I bid too little too early and got drunk so I missed it.

Just wanted to be sure the 20rzt would be the best pump for me.

The pump will work very well. It would take a lot more than what you propose to make it a bad choice.

you get the MD20RZ? Howd the purchase go?

200$ for the pump is kinda high. Think I might just wait for one to show up on ebay again.

md30rz's show up on ebay more often than md20rz's
plus most are 100vac (laser cooling pumps)

Think a 30rz is a little too much for me. Neither are up right now anyways =(

They're slightly cheaper here http://www.aquadirect.com/store/cust...me.php?cat=239. What I'd actually like to see is a head-to-head review of the Iwakis and the Blueline "clones" from the same designer.

Purchase went fine. They drop ship from Iwaki so my order took about 7 days to arrive. I was tired of waiting to find one on e-bay so I bit the bullet and bought it. Been happy ever since.

Oh yeah one more question, Voltage? Doesnt the 20RZT come in 115v and 240v and something else?

They list a normal one (no voltage listed) and a 100v one, is the "normal" one 115v US?

Here's my question:
On CustomAquatic, they advertise an MD20-RLZT. Iwaki does NOT make that. Did you get an RZT or an RLT?
There's a difference, so I'd like to know.

Uh L isnt a pressure rating thing. Z stands for High Pressure. Pretty sure L stands for US voltage. Hence I just answered my own question from above :D

dangerous to assume, ask
*should be* 115v

Then what does the X stand for? like RLXT?

Beercan- one other thing:
It says that the pump is NOT threaded. How did you get your hoses on it? I've got 1/2" clearflex and I'm not sure it will stretch over a huge fitting like that.

The fitting isnt that huge, 1/2" ID tubing is no problem.

Both fittings in and out? Are they barbed?

High flow, low pressure.

If the pump head is NOT threaded, then yes it has fixed barbs.

MVC 02-04-2005 01:40 PM

Nikhsub1, out of curiosity, what are you using to power the RD-30? I was looking at that pump but wasn't sure I wanted to deal with 24VDC.
