Got my pump.

[Volenti]

Oh it will add heat into the water, mearly from the friction of the water against everything else, especially since it's a higher pressure pump than most mag drive's.

No, No it wont, because ive already tested it.

[Volenti]

You're giving the water kenetic energy when you pump it, that energy is converted to heat in your watercooling loop because of friction of the water against the tubing, water block and between individual water molecules.

Kenetic energy in, heat energy out.

Get outa here with you Kenetic energy crap. Which will add like, .05c to the water.

And NO, the pump doesnt add heat to the water. Did I not just say, I tested it?

Go try and show-off somewhere else.

Volenti is right, but it's not relevant, and is a factor regardless of the pump you use.

There will be heat transferred to your water from the pump, believe it (it's true for everybody). In this case, the heat comes from the motor's coils, and is transmitted through the motor shaft, and possible the motor housing too.

In an Eheim, the coils heat up too, and the heat is transmitted right through the housing, which happens to sit right in the middle of all the coils. There is not a lot of room to isolate this, because the further away the coils are from the impeller, the less efficient the pump becomes. Usually, it's just 3-5 mm plastic.

If I was you, I'd leave your pump just the way it is. Don't try to mod it, don't try to isolate the housing from the motor (you might throw off the alignment).

How are you doing with building a box?

Ya I wouldnt even attempt moding my pump.

Regardless, I see no change in the water's temp.

And Im still thinking aobut the box, I dont know what materials to use.

I think Ill have it be wood on outside, then foams and sound surpressing material on the inside.

[bigben2k]

That sounds good Cieprus, let us know how you're doing.

I'm glad to hear that you don't notice any temp increase from the pump, but just to add to that, the heat (from an Eheim, for example) is very small and usually less than 10 Watts. How did you measure it?

Well, I made my own In-Line temp sensor.

From a modded outdoor/indoor temp sensor.

It ranges -50c-70c.

Im working on my case window, cause I took out the 2 120mm fans and needed the window.

Its coming along well.

And I havnt started the pump box yet.

[Cieprus]

I just noticed, the pump I got uses motor brushes, kinda like the dremal.

How long will these damn things last?

Im gonna have to replace them alot.

DAMNIT...

[Cieprus]

Oh ya, It saids to add 1 tablesoopn of oil before every startup...

Is it bad to have a little oil running through the system????

[bigben2k]

Oil is necessary, to keep the impeller lubed, but it shouldn't affect the rig (oil won't mix with water). The oil should stick to the insides of the housing, and the extra will end up in the water, so if you can, do the lube job with a bucket, THEN install your pump in your rig.

You don't need to worry about the brushes. You'll replace that pump long before they wear out (right?).

Ok.

The brushes...I dunno, I noticed a little were on there, like the shaping began, but other then that I have no idea.

[bigben2k]

That's pretty normal, the brushes shape up, then slowly grind down. Just make sure you're able to get replacement brushes, if you're going to use it for a while. (Personally, I like having spare parts, but then I'm a pack rat )

Ya I guess Im a pack rat aswell.

It pains me to throw anything with any use away.

doesnt sound like something id want for a watercooled rig. you couldve had a mag-drive pump by now if you just ordered one last week
you also wouldnt have to worry about oil leaking into the coolant or brushes wearing down...

Oil isnt bad, it disipatates heat very well...
And all motors use brushes, even your dremel uses them, and you can replace the dremels too...

And If I had the money I would have ordered one...

In not rich man.

[Cyco-Dude]

lol, but werent you going to get one befor?? i was under the impressoin that you wouldve gotten one, if they were in stock.
mag-drive pumps are brushless i do believe....it just comes down to more maintenance for the type of pump you have. if that doesnt bother you, then np

Ohhhh...

Ya I went to petsmart & petco, both had no pumps...

I was going to get the Danner 350...

So now I have this 350, it should do fine till I get the Danner.

Or whatever pump I get...
