Iwaki Love

[MaxxxRacer]

I just got my Iwaki WMD20RLT and I absolutely love it. Though i have no point of reference for pumps, this thing pumps like a monster. I was testing it in my bathtub and it turned my 1/2inch ID tubing into a garden hose. It takes about 4 seconds to pump a gallon of water. and the head pressure is amazing. I moved the head hight between 1 and 7 feet and I saw 0 change in pressure. (granted i have no precise tools to measure it, but looking how the water was flowing gave me a good indication).

And to boot, the thing is nearly silent. As long as u run it on somethign soft (carpet, padding, etc.). The only noise i was getting in the system was from little tiny bubbles cuasing some cavitation in the pump. But running the pump for a little while would certainly get rid of that.

I'm sure you guys all know how good these pumps are, but here is just one more satisfied iwaki customer.

They are very nice pumps.

They are also designed to operate against some amount of back-pressure, otherwise you will get the cavitation. Only the RX series are designed to operate against no back-pressure at all.

Assuming you're on US 60Hz power, the plain R's are designed to run at no higher than around 10-12LPM before you'll probably start to experience some cavitation.

Thanks for the info cathar. Well I will be running with TDX and maze 4 with dual 120mm fan heatercore. So i think it should restrict it enough to remove cavitation.
