+Mitch Posted January 15, 2013 Share Posted January 15, 2013 I broke my Mag5 impeller shaft I know the shaft itself is not sold separately, but I would have to get a replacement impeller, which comes with the shaft, for <$20. Since the shafts are only made of ceramic, I was hoping to find something more durable. I did a few searches and see that some people have tried using carbon fiber or stainless steel rods. Has anyone on ARC had success doing either? Any and all suggestions welcomed. TIA Link to comment Share on other sites More sharing options...
(Bio)³ Posted January 15, 2013 Share Posted January 15, 2013 I'd call the pond pump store in cedar park and ask them since they have all repair parts. Might have something aftermarket! Link to comment Share on other sites More sharing options...
+Mitch Posted January 15, 2013 Author Share Posted January 15, 2013 I called them yesterday and they had only mentioned that they have replacement impeller. Link to comment Share on other sites More sharing options...

+Mitch Posted January 15, 2013 Author Share Posted January 15, 2013 I may have one to be honest....let me check when I get home...if I have it still....it is yours Thanks! I'll for sure grab it if you find it. However, i'm still trying to figure out a better long term solution as i KNOW i'll end up breaking the ceramic shaft many more times.

+Mitch Posted January 16, 2013 Author Share Posted January 16, 2013 I picked up a 4 mm carbon fiber rod from Hobby Town for $6 for a 1 m length and which measures 3.81 +/- per caliper. It fits the impeller, but binds a bit. The ceramic shaft has an OD of 3.76 mm per caliper. After a little sand papering, impeller rotates very smoothly on the CF shaft. Per suggestion from Hobby Town guy, I put a little super glue on the cut end. Pump works perfectly now. I'll try to remember to update this thread after some time and report how it's doing.

Timfish Posted January 17, 2013 Share Posted January 17, 2013 Stainless steel and carbon fiber are more flexable than ceramic but ceramic is harder so it should wear a lot longer than stainless steel and certainly carbon fiber and might also have less fricton than either.
