12v bilge pumps

[stepback]

I'm new to this forum and to water cooling.

I have been researching what parts I want to use in this system here is a list of what I have so far.

YY-0221b cube server case
AMD Athlon XP 1800+ (Won from XXP online contest)
Gigabyte Motherboard Model #GA7-DX (Won from XXP online contest) I will be upgrading when the is a good DDR333 MoBo
256 meg of kingmax DDR333 cas 2.5
Adaptec 2940UW2 scsi card
2 x 18.6 gig seagate barcuda's
Heater core from a 1987 Ford Escort w/AC
Custom made copper water block (Have a mill at work :D )

ok, Here's my question

Has anyone tried using a 12v bilge pump to move there water.
I have found a couple of different small bilge pump that have great flow rates and have low current draws.

Here's some links

Any thoughts on these??

I am not sure but I think that overclock-watercool (http://www.overclock-watercool.com) has the third pump you mentioned for sale so I guess that they would work well. wish I had that case.

See the note they have on overclock-watercool about 12v pumps. They are not quiet, and I imagine they draw alot of current.

You'll love the cube, I sure do.

Noise isn't a problem and I planed on using the Rule 1100 as I can get from a marine dealer down the street for 25 buck's. And it seams to be a better pump then the Atwood's Overclock-Watercool is selling. But then datasheets and real world operation are two different things. ;)
I really don't want to mod the power supply to run a 110 volt pump and run a relay to start it. Or even worse run a separate power cord. I would like to keep everything inside the case with minimal mods. Don't get me wrong this thing has dermel tool written all over it and I plan on making some case mods but mostly fans and blowholes.:D

Edit: The case I have now has enough fans on it , if it had wings it would take off.

I used a 12v bilge for about a week. It worked very well and the cost was like $14. Many here or at [H] said that it would burn out in a month or so. I told them hog wash. Use your own judgment. I say if it has a long life low amp motor(which this did) it will run for along time.

Cool beans man.

Have a blast playin' in all that acreage that case gives ya, here a pic of mine. No color on it yet, but who knows.

hey dig,

What is that tank in the front made out of ??

[Diggrr]

3 1/4 cast acrylic tubing, plexiglass for the flat pieces. Cast acrylic (at least at mcmaster.com) costs $70 for a 6ft. piece. Glad I already had it.
The shroud around it is made from aluminum flashing epoxied together. (3 pieces made seperate) The bottom is 3/4 inch pine covered with the flashing.

Personally I wouldn't use a bilge pump. I had a rule 500 gph for a while but it was to noisy and to big for my case. Bilge pumps also don't last as long as mag drive pumps. Bilge pumps use a normal dc motor which is totaly sealed off from the water; if the seal leaks the pump eventually dies. By looking at Rules website it looks as if a bilge would last you a few months with continuous use. You can always try one out yourself and see if it lasts longer. Bilges are used in very icky conditions some times so that may be why they have a lower life expectancy. What I would suggest is making a relay switch so that your ac powered pump will turn on when you hit the power button.

Diggrr; your a god, both good and evil! Let me explain. I've been looking all over for an Acrylic supplier, your tip above for the site has helped me out (that makes you good god:) ). The fact that I now have all kinds of crazied plans for cases involving Acrylic, and now have the site to buy them from, but can't yet (that make you evil:) ). Thank you!

You can pick up bilge pumps in the boating section of Kmart!

[FrozenInHI]

I don't think a bilge pump would be good for this application, as bilge pumps are designed for short periods of use. You'll need to be running it all the time and at full load to boot, whereas in boats you need to run it only when the bilge reaches a level, and once it lowers it sufficiently it turns off. i think the quality of the pump is not gonna be enough. that's why pond pumps are better, they're used constantly, so they make them durable.

Buy a 12V LVM Amazon. The are continually rated and will pump more water and deliver more head then most fountain pumps.

Pulls a maximum of 4.5 Amps, max flow of 18L/min and max head of 10m.

I have no idea where you would buy these in the states as I live in Oz. I purchased mine from a boat shop. These units are made in the UK.
