i have 2 of the 6100.10 powerheads and they are vibrating fairly loud i pulled them apart and noticed some wear on the shaft how much trouble or cost is it to fix this problem? Thanks- Gary

So i just pull the old impeller and shaft out and slide the new ones in?.. thats easy enough! Thanks for the help!

since your on this subject, do you mind if i ask a few questions reguarding this.
I have the older version of brown 6100 pumps and they work great still. (crossing my fingers)
i was cleaning the impeller, and i noticed that the impeller has the breaks still on it. and work great.
i purchased a newer black model 6100 and the impeller doesnt have those. but the motor has the same color with the imprints for the breaks.
I also noticed that the impeller number on the Tunze website has changed a few times.
Do the impellers no longer come with breaks? just curious for the differences or improvements.
thanks.

From 2002 until 2004 all Stream pumps used the 6080.600 drive unit, the brakes are required on models 6060 and 6080 to stop a backwards rotation, on a 6000, 6100 or 6200 they are essentially like an appendix, they don't do anything except potentially cause problems on rapid on and off cycles. When the wavebox came out which rapidly turns on and off, we had to change the design so in late 2004 with the wavebox we came out with the 6100.600, this sandwiched a very tiny oring under the drive shaft to lock in the brakes. In 2006 demand was up and while the old logic was using the same part saved storage space and reduced production costs, we had a new problem, meeting demand. The 6100.700 and 6200.700 were introduced because they saved a great deal of labor, take a look at a 6100.600, 11 hand assembled parts, you can imagine how much this slowed things down. All still exist, 6060 and 6080 and any 6130 (few were made) still require 6080.600. For a 6000 or 6100 you should use 6100.700, for a wavebox or 6200 you should use 6200.700. 6100.600 exists for the rare case where a much older 6000 or 6100 has an imperfection in the rotor well and the play of the multiple parts results in less noise, there is enough give to overcome a slight angle of the well or small bump or groove. This would largely be because pumps made from 2002-2004 were made entirely by hand, the driver were hand soldered, the motors were hand soldered and the polyurethane potting was hand poured and the three molded plastic pieces of the motor were glued by hand. These first pumps have a cumulation of nearly 100 manhours in them if you count programming the injection molder and installing the molds to warehousing and sorting the pieces to final packaging. It just is no longer possible to do it that way and be competitive, we have kept with producing the pumps in Germany but robots now handle much of the work and the designs are simplified to the fewest number of parts needed for a quality product.
