question about powerful pumps

[saint-francis]

I am going to mount a very large radiator about 10 feet under my pc and I need a pump to run the coolant through the radiator and up to the pc. I don't care in any way how large the pump is or how noisy. It just needs to be POWERFUL. I am planing to use a radiator from a Honda. The one I have in mind as relatively small as far automotive radiators go. I am placing the radiator and pump in the basement to keep noise and unsightly equipment out of my apartment. Also the basement is always cooler than my apartment. Of course cost is a concern here. I am not really sure what kind of pump to use at all. It would be nice if I could keep everything AC.

powerful enough?

[saint-francis]

Yeah it is powerful enough. :rofl:

The max head is 33'. Why not just use two MCP355's? They have a 20' head and only cost about $70. The one you linked me to costs $240.

If noise is no concern, and if you're using a car rad, heat dump will be of little concern, you can get yourself a cheap garden pump off eBay for well under $100.

DDC's are only 3.1 and 3.2 now.

New MCP355's are 3.2's... They arent as powerful. You get only 12 Feet head, even with Petras top. Never mind the Reliability issues.

The RD-30 is the most powerful pump, only DDC3.2 x 3 or a D5 x 3 can match up.

My guess is that Laing could not put up with RMAs on the DCCs so they reduce their performance to make them last longer. Ofc this sucks for us but to be honest I own 4 DCCs and one is dead and a second one refuses to start from time to time. So I am looking into other options as well.

What about some other options like those:

Alphacool AP1510 centrifugal pump 12Volts

Maximum output new defined! New revision!

With the external adjustable DC voltage converters (12, 15, 18, 21 and 24 Volts) you may adapt the delivery rate of your pump to your own configuration. The 1500 litres which are achieved at the highest level satisfy even the most pretentious expectations.
The pump is attached at the transformer, and the transformer at the power pack of the PC.
NO 230V connection is needed! The extra power cable is superfluous as the pump turns on/off automatically with the PC.

This centrifugal pump is conceived for the thoroughgoing continuous use. The pump sells with 36 months warranty. Due to the G1/4" internal screw thread, the pump is compatible with all types of connections.

Powered by OASE !

Technical Data:
Pump performance: max. 1500 l/h
Delivery height: 6m
Power consumption: 17 W
Connection: G1/4"-connections
Sound level: approx. 21-35 dBA
Dimensions L x W x H: 115 x 100 x 80 mm
DC-voltage converter L x W x H: 118 x 75 x 60 mm
Weight: ca. 720g


We need a replacement for the DDC now and this does not look bad. Anyone tried it yet?

I've been looking into high power pumps for use with a crown vic radiator and this one is looking like the best I can find so far.

This thing is huge!!!! There are big pumps out there Iwaki or not that can blow your WC set up into pieces. The point is to find something small, quiet and powerful enough for our WC needs.

[Agent11]

heheh. Yes.

I plan on using either AN hose or soft copper tubing so pressure will be under control..

Not for your average setup for sure though.

[JargonGR]

And I guess any wb with plexi tops would be in danger too and the same for plexi reservoirs.

Damn you intrigue me, I have an 700 litre per minute pump 230V that we use at work for emptying water tanks or floodeed spaces using 3" hoses. Maybe I could undervolt it and play around a bit in the future witrh old hardware.

[saint-francis]

Are these my only options for pumps? I'd like to keep it under $150. Is this unrealistic?

[IanY]

Here you go, enough of the girly wimpy limp RD30s :D

This one has 45 feet of head lol

LOL Iany! That pump actually looks nice though.

One way to use a truly massive pump efficiently is to have a reservoir above the computer which feeds via the radiator to the waterblock, then into another reservoir below the computer. The huge pump is controlled by a float switch and pumps water from the bottom reservoir to the top one. With enough water in the system the pump will only switch on now and again.

edit: changed `the way` to `one way` :-)

You can find very powerful pumps for around 150, the problem is that you are usually sacrificing something, like brushless for brushed.

At some point you have to ask yourself if a possible failure because of saving 150 dollars is worth the risk.
I would buy the best part possible and save for the next best part possible, especially on things like pumps. It is very unlikely that a new bigger badder pump will come along before you complete your build.

Search for iwaki wmd-numeral pumps, instead of a japanese made motor they have an american one and are usually less expensive.

I've been looking into aftermarket electric radiator fans, and they can be pretty expensive. 250 bucks for dual fans and a shroud.. However in the end it will be worth it, and it will be an investment.

I would get the infrastructure of your build first.. Pump, radiator, fans, hose and case one at a time and get the best possible... A bonus being that you will have something to fondle as you save up for the next part ;)

If you are getting new waterblocks I would get them last being as there seem to be new ones coming out fairly frequently or you may decide to build your own :)

Jargon, let us know how it turns out if you play around with that pump! sounds like fun.
