12volt Water pump goodness - Page 3

euh... ECUPirate: a watercooled 486 DX2-66 running Windows XP?!?! Can you actually do that?

And dude, your water cooling parts cost more than the entire computer itself!

hehehe...

I just dig that sweet overclock, baby. ...that puter cost alot of bucks when I bought it, like 8 or 9 years ago.

It takes about 23 minutes to load Winxp on startup, and another 5 minutes to open internet explorer (damn MS bloatware), but after that, I'm home free.

(I'm really in the 2.7Ghz range..

Johnson makes a pump virtually identical to the Jabsco (probably made by the same people, really). They also do a "bigger brother" which, although identical in size, has improved specs:

Continuously rated, the Johnson CM30P7-1 pump runs on 12V (just plug into your PSU), 2.2A, 26W; pumps 356 GPH / 22.5 l/min at 3ft. head.

Dimensions are 18cm long by 5.5 cm width.

The only problem is the price... $179,-- i.e. £130,-- :eeek: Regardless, I decided this will be the one for my project.

Pics below:

Questions, cooments?

Nice! Wonder how quiet it will be..and how hot it will run!

That just ROCKS!!!

It's a little bigger then the jabsco.

@ Awsterink: like the Jabsco the pump is DC magnetic drive, and as such there is neither gear noise nor that typical 50/60 Hz "buzz" you get in mains AC powered gear. It is absolutely quiet. Another user mounted his Jabsco on a metal garage door and even on this acoustic platform he had to put his hand on it to check that it was running.

I expect that, just as the Jabsco, it will run a bit hot, to the extent that keeping your hand on it will be uncomfortable, I guess about 50ºC. However two users have mounted their Jabsco inside the PC case with no adverse effect on case temperature., and no heat is passed on to the coolant.

The thing weighs a reassuringly solid 0.6 kg (1.3 lb) by the way, and should be mounted with a 3 amp in-line fuse.

What can I say? It's the daddy. Pity about the price...

but perfection costs.

Hmmm. Thanks for that info. I just put a larger reservoir in my WC setup and moved the reservoir to the top of the case, all in an effort to reduce air bubbles. But unfortunately it also seems to create more backpressure, because my Eheim started humming like crazy...

I may first try a large tank at the bottom (less lift, less backpressure), see how that goes. Otherwise, I'll be shelling out the big bucks for one of these babies!

Thanks,

Arjen

It's a great pump. The only problem I had was how to connect it to 1/2" tubing, as the hose connectors are 20mm O/D (about 3/4") and 15mm I/D...

No problemo. Just drill a screw thread inside the pump connectors and screw in 3/8 NPT (or BSPT) to 1/2" barb insert fittings (with some teflon tape or some sealant) and presto! Adapted to 1/2" tubing. A neat and clean solution.

Just ordered mine, now all I have to do is make a quick stop at the Shack to get the accessories.

Here some pics to show the barb installed:

Here fitted to the rad.
