Enheim 1046/1048 mod

I had a prob with a noisy 1048. The guy who sold me the pump sent me this link.

It's in German, but the pictures speak for themselves. I applied the mod yesterday and it's impressively working well. It became a lot more silent.
Might help some others. Sorry if this has been posted before.

I got a 1048 and can't hear it. Do you have bubbles in your system that is what can make the noise louder.

Well, the mod helped to reduce the noise, but it's still not completely not silent. Yes, I have bubbles in my circuit and I ran out of ideas to get rid of them (shaking the rad, put a piece of blue filter into the innovatek res, let the res open) nothing.

That's not the safest mod I'm afraid. I tried that on couple of submersive pumps and they all had troubles starting or stopped after a while and where not moving water while the engine was heating. And for that reason I do not recommend doing the above

thats weird the bubbles aren't coming out. I'm using a T line and the bubbles cleared out just fine. How long have you been running your system.

if that teflon gets loose in there you could ruin your pump. i wouldn't risk it, my 1250 gives off a lil vibration i can feel through my desk, but no noise.

That's just locking the impeller to the rotor, much like the ViaAqua and the MaxiJet mod. You can use a good waterproof glue to get the same result, with less danger involved.

By the way, the impeller is made that way because as a fountain pump or aquarium pump (which they are intended) can get solids up the tubing...this helps keep the impeller from crashing and breaking.
As a watercooling pump, I should hope you'd have no solids in your tubing .

I'd agree that the tape isn't a great idea. If it tangles and stops that rotor, you can have a meltdown.

I just pushed the power switch yesterday with the W/C all set up after a 24hours leak test outside the case. So far so good, although now you guys freaked me out with this tape tangling stories .
Although I don't really see how it will happen as the rotor is totally covering the tape. Anyway. I applied this on my 1046 which I use only for watercooling my 9800Pro in a secondary W/C circuit with single rad. So I hope if there is anything going wrong with the pump, I will see artifacts on the screen before the GPU actually melts down.
I have another 1048 on the primary W/C circuit with dual rad dedicated to the CPU cooling without this tape mod as it's working fine. So far I got 30-31 degrees celcius on my P4C 3.0Ghz FSB800 (idle). So bubble doesn't seem to be an issue. I wonder if what I see inside the pipes can come from this Innovatek water additive. It's kinda 'soapy' when I have some on my hands.

My 1048 has not given me any probs, yet.

Here it is translated to English

Google is so KEWL.

Geeez That translation is a laugh and a half

"In most cases loud pumps are to be due however to a badly aired out system!"

"Also a renewed careful exhaust of the entire water circulation did not bring remedy."

Positively flatulent
