Iwaki MD-20RZG-2?

Gulp35 · 12-24-2005, 12:05 AM

My dad just received one of these pumps from ebay, and when I go to look it up I see that there is no RZG model listed.

What type of pump do I have?
here is the aution:

This was actually quite a good deal b/c the post office broke the one we won and the company is sending us a new one for no additional cost! hopefully we can get this broken one *the outlet snapped off but did not shatter* to work so we can have 2 iwaki's for the price of one!!!. If only they were WMDs not MDs.

From the specs on the plate, it looks to be about as perfect as it gets for computer water-cooling use. Go read one of the threads on what makes for an ideal pump. The hydraulic specs on that pump at 60Hz are pretty much exactly it. If they could take the 50Hz peak flow with the 60Hz peak pressure, I doubt you could find anything better so long as you're using a 2 x 120mm radiator or larger.

Of course, the "ideal" pump would be physically smaller, and quieter, and draw slightly less power, but you've pretty much hit the nail on the head from the Iwaki range.

The specs look like any other 100v 20rz no?

The peak flow is a little higher than a regular 20RZ.

enjoy it, I love my MD-30RZ 100v

btw, the MD are slightly better than WMD models (noise primarily)

may be performance benefits to the WMDs over the MDs (less heat to the water)

what, a couple watts more into the water?

my MD30-RZ has now been running 3 years 24x7, rock solid

some may care about added heat from a MD vs WMD but does not concern me due to external active chiller that keeps coolant constant

err - unless my eyes deceive me this is a vacuum pump ......

Not sure about vacuum, but it is 3 phase run... only large biz and farms have that capability! Would need to replace motor, so no deal.
