New outrageous Panworld pumps
 

Here are the specs for the new PIZ series:

Now the 20PI-Z-D has a similar curve to the MD30RZ
with a heat output of a MD 20RZ at (input X output) of 55 x 30 watts!!!
Head=~5.5 meters @ Flow=~9.5-10 LPM

Calculations:
10PI-Z-D, WB delta = 16.5C, Water delta = 118 * 0.041 = 4.84C, Total CPU Temp = 21.34C above ambient

Doing the same math for the 20PI-Z-D with 30 watts output:
We'll get the following flow rates, and also the corresponding radiator C/W, and waterblock C/W at that flow rate:
~10LPM, 0.039, 0.157.

WB delta = 100W * 0.157C/W = 15.7C,
Water delta = 130 * 0.039 = 5.07C,
Total CPU Temp = 20.8C above ambient.

So now we have the following temps above ambient with the following pumps:
(Originally by Cathar at ProCooling - the reds are my additions)

+20.8C => Panworld 20PI-Z-D
+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
+21.34C=> Panworld 10PI-Z-D
+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

Comments would be welcome.

Any pictures? can't seem to google anything on them

humm ive seen that yellow one somewhere before :p

I am just about to bring my RD-30 online, but this does look interesting. Any ideas on price / availability? Noise? Anybody using one? Can you vary the motor speed without damage? Do they sell through distribution?

This line of pumps deserves further investigation. Someone interested should give them a call. The 24 VDC could be a little awkward, but the Iwaki RD-30 has a similar drawback...

Links to sources (retailers) of this pump? Price?

I liked the one with a 4-20mA speed control - for testing
dunno about accuracy or repeatability

You are not reffering to the PI series but the PX series.
You are reffering specifically to the AC pump.
Havn't seen this regarding the DC pump.

AC pump with integrated VFD? sweet but unlikely...or expensive

That was the feature that caught my eye, also. The variable speed with integrated process control made me a little jealous. I had no idea that feature would be available. I have had to build a variable converter (3-terminal regulators) to get variable speed. I still haven't fired it up yet -so no comment on the effectiveness.

I could have controlled the pump directly with my onboard PLC. Mabye we will know more about these by the time I build another system...

so has anyone gotten their hands on a PI yet?

Soooo anyone ever find these things?

Panworld Sales in singapore quoted me:

NH-15PI-Z-D - SING DOLLARS 560 EACH
NH-20PI-Z-D - SING DOLLARS 680 EACH

With 50 % discouts for orders over five (and 60% for over 10 :)). Since i was not ordering five, i couldn't justify the ~520AUD for the purchase.

phextwin, what units are those prices in??? 500 for a pump that isnt much better than a md20 is not much of a deal imo, especially when you can get a rd-30 for less.

Singaporian (SING) dollars and australian (AUD) dollars.

Can't get rd-30's in aust that i know of unfortunatly, i asked iwaki aust and they don't do single unit orders, and declined to tell me of where i could get some :(. Only IWAKI's that i can find on ebay are MD-40's, 15's & 10's (not the z's either). Bleh.

Also, the 20-PI is ~= md30rz, but is DC = more efficient :), though of course, real world gains would be negligable :/

Phextwin - why would you bother with these pumps when you can still get a MCP 600 in australia? (though i see the prices are still quite high there for this pump.)

As i am stuck...can't get the mcp 600
- neither in Israel or the US
(Cooltechnica seem to be "closed" - no replies to emails....i hope everything is o.k. there.)
I might try these pump out.

Phextwin - I would be willing to part with my Iwaki MD-30RZ for the right offer...

nimrod, that is odd. I have friend over at XS buying mcp600's from cooltechnica right and left. i know of 3 who bought them in the last couple of weeks.

Wow they look nice, 680 singapore dollars is a lot of cash for a pump though. :/

Price update. PanWorld quoted me the following prices yesterday:

15PI-Z-D is US$209
20PI-Z-D is US$253
30PI-Z-D is US$275

and noted that the 20PI-Z-D is currently out of stock. The pumps will run at 18VDC to 36VDC, they wont start at 12VDC so seperate power would be required.

You can get a small stepup transformer for in-car use to run it off your PSU. I got one with my AP1500 that had switched 12,15,18,21,24V and modified it to run true variable 12-24V off a pot on the front bezel.

Nice work Risky.

A 24V supply hooked up off the mains is also pretty easy to do, or you could buy a small psu prebuilt.

And you'll still be getting 50% discount for 5 and 60% for 10 pumps?
Could be interesting to see how many people would buy one for $253x0.4=$101.2=€78.67.

nice old thread. Now did anyone ever even see one of these things in person? Ever?

I hunted for awhile and never found anything past this thread :shrug:
