Aquacomputer Pump Issues.

post #1 of 6
Thread Starter 
Back in December last year, I started hearing screeching noises and heavy vibration in my case, Took the side panel off and put my hand on the pump and realized the screeching/vibrations were coming from the pump, If I wiggled the pump you can hear the screeching more and more. Well emailed and called aquacomputer about this and going back and forth, they sent me a new impeller and everything was fine. Fast forward to last night, the same thing started happening again. What would you guys do in my situation? Have any of you had this happen before?


Here are some pictures of the old impeller.

Just got off the phone with Aquacomputer, He is claiming that it's pure distilled water that is causing the impeller to wear out and rub on the inner part of the pump. I don't even know what to say about this. Have any of you experienced any of this before?

@Shoggy Any suggestions?

pure water is the issue.
pumps need lubricant.
as water becomes saturated with particulates from your water loop, it's more like sand paper to the pump than a lubricant.

I currently own 10 different D5 pumps for all of my water cooling rigs, these pumps range in age from new to 7 years old. I have never had a pump issue like the one you have shown. I also have never used just pure distilled water in any of my systems.

I use Prestone antifreeze in all of my water loops and I have for 15 years.

take a look at the premixes offered by swiftech, and koolance. these companies require you to use there premix coolants, if you expect them to honor there warranties.

what you will notice is that there premix coolants, have a lot in common with antifreeze.

I had this exact same issue on my pump aswell. After 4 years my pump looked the same. In the end I just bought a new pump. But yes, most likely due to particles in your water.

I know there are people out there that are only using distilled water with kill coil. Any of you having issues?

In the end we will never know what really happened there but I am very convinced that the pump itself is not the problem here.

Anyway, we had some phone conversations and I think we found a reasonable solution for both sides smile.gif
