I just purchased new 6105 and 6055 pumps to run in sequential mode using a Digital Aquatics ReefKeeper Elite APC module. The 6055 runs fine, but the 6105 clicks each time it switches speeds. I thought I read that this issue had been corrected. Is this still a problem and how can it be corrected so I can enjoy the silence once again?
New 6105 Clicking

It should not click for speed changes, but it would click in off and on cycles, this click is greatly reduced by the 3005.740 disk which was the last upgrade, but it is not completely eliminated. This disk has been used since last July. It would be worth checking that it is present and properly installed, it should be at the base of the shaft right above the blue bushing and the black disk has a slotted side which must be facing and in contact with the bottom of the drive magnet.
I would prefer not to as it won't likely destroy the pump, the odds are high that you will scour or damage the internal wall of the pump. We did send the parts on Friday and I would imagine you will get them very very soon. If you must run it, I would run it at a constant and lower speed.
Roger - Thanks for sending the parts so quickly, however, I am now really confused! The bushing and disk were definitely missing, but the metal shaft does not extend beyond the drive unit giving me no way to install the bushing. The shaft is attached to the motor block and the drive unit slides on to it. From what I can tell from the manual diagram, the shaft should be a part of the drive unit. What am I missing here?
You have a brand new model pump, this is something we have been working on for over a year, the shaft is fixed in the pump and no longer removable. The disk will just slide down the shaft into the pump, please do check that one is not already present down there. This new design is quieter as having the shaft fixed on both ends allowed more play and if the parts were out of alignment there was more noise. I apologize, I know we discussed this at the factory but I was under the impression this style pump would not be shipping until November. I guess they got a bit ahead.
Sure, I am heading out to lunch and to drop off repairs I completed for a LFS. I will be back by 2. 512-833-7546
I think all you need to do is double check in a bright room or with a pen light that there is no disk down on the shaft and if not you just start the disk on the shaft and use the drive unit to push it down all the way to the bottom. This design is much quieter and will be the only design going forward. You won't use the light blue grommet at the end of the shaft. I have to imagine the disk was left out and that is the only cause of any noise.

It will always have some hum, at full power (24V) the 6105 with fixed shaft should be about 58-60db after a couple weeks of running in, this is about 4db less than the old version. They are generally louder the first 2 weeks but this will gradually improve as the parts wear in and seat.

Roger, I was curious how you guys got these dB numbers? That is fairly loud, and I would put these pumps-even with the 24v jumper- in the low 20's tops. I have 2- 20 decibel fans that are louder than the 6105s.
