So I have been running my water cooling loop successfully for close to 4 years now. (With regular periodical maintenance).
A week ago my pump started making a slight noise. At first I thought it was some fan blade hitting a wire or something. The noise was intermittent and would come and go randomly. Unfortunately, on friday, there a rather loud knocking noise and the pump stopped completely.
Drained my loop and dismantled my pump to find that the rotor has worn out
Here are some pics of the pump. The ceramic bearing on the stator looks decent but the part of rotor that sits on the bearing is complete worn out.
So does anyone have a spare D5 to sell? Or a dead D5 from which i can salvage the rotor?
PS - In order to satisfy my curiosity of seeing it work, I made the terrible choice of trying to make the pump run while open. Without water acting as the lubricant, the rotor wore out very fast!!
Learning - Never ever run the D5 pump without water!
PPS - By rough estimates, my pump ran for about 20k hours. That is less than the 50k hour MTBF for D5 pump. The only logical reason I can conclude for my pump reduced life span is the way I was using it in a dual bay pump+res combo. The way my loop was designed, bleeding it took quite sometime and I presume this air circulating in the pump had a bad impact on the pump life.
