It was fall cleanup not long ago and im one of those guys thats like to go around and pick stuff up lol, anyway i picked up a rug cleaner tor the motor out of it and at the time what i thought was a solenoid water valve so i hook a plug to it and plug it in and put the hose in some water and all i can say is wtf this ain't no solenoid water valve its a freaking pump!!!!.

My question is has anyone used a pump like this before to pump liquid through there CPU chiller? It has a good flow rate by the amount of water it was spitting out.

We use pumps like that in our chillers... Well similar in design at least... We use em for the oil.

It has a good flow frate but the duty cycle is only based on a few hours continuous use. Not 24/7

Yes but if its got chilled liquid flowing through it it should keep cool and not burnout.

I've seen ur chillers and those pumps i think are ur standard impeller pumps arn't they? This small pump i have i believe it pulsates (no impeller).

You're talking about the 30HX Series correct?

I'm not sure exactly how the pump works. I'd have to ask engineering.

Not always true. Often the components are somewhat seperated, meaning even if you have -20c liquid going through, you may still have a 60+ degree pump. However the best way is always to find out :D

If it is rated for industrial service, it should be able to handle 170F.

I dought this pump would reach 60c or even 20c if chilled liquid is going throught it, the pump is too small to have its components seperated or insulated my any real means. I can pretty well close my hand around the pump its that small.

I've tried looking up this pump but i never even got close to finding some specs on it feel free to do a search urself i would like to know what its specs are too.

The only kind of isolation that would prevent heat transfer would be a vacuum isolation, and you aren't gonna see that with these pumps.

The outer shell will be affected by the water, and in turn the internal components.

So what are u saying that the pump will ruin itself by pumping chilled liquid?

No, I was saying that the internal temp of the pump shouldn't get all that hot. At least not a pump of THAT size and nature. :)

Thats exactly what i was thinking its too small to isolate the heat in the body of this pump.

It's not the heat from the motor thats the problem,as ung eluded too,if its not rated for continious use the bearings just won't hold up. at very cold temps metal contracts putting even more stress on the pump.

Oh, that's a pressure water pump, I have been seeing them used for sprinkling reptile aquariums.
They had small flow, but they was able to flow through very small pipes.

Yea if i put my finger over the inlet it creates a suction (an impeller pump won't do that) thats what i think this is no bearings or nothing like that. I would like to see the insides of a pump like this but im not gonna ruin mine doing that.

It would be extremly easy to insulate a pump like this. :D

You should make an chiller with 6mm OD coolant pipes :)

I remember when I compared this pump with an aquarium pump. The results for aquarium pump were 400l/h (it was
a 800l/h, 5-10W pump), for pressure pump ~50l/h. The tube was 14mm ID.

Hm, those pressure pumps can be cheap, on stock-exchange I bought a few of them and one piece costed 5 dollars.

Also, they're a bit noisy and do a quite vibrations.

Yea it is kinda noisy but u wouldn't hear anything with 2" of GREAT STUFF FOAM surrounding it. :)
