I've heard of some early on, but the problems were identified and have, I believe, been solved.Has anyone had or know of, first hand, failures of Sigma Tek's AEON Piston Air Pump ???

Had a good long talk with them last year at OSH. They had a "D"rev and were waiting on FAA approval. Should be available by now. They told me if it failed again to call them directly. They explained to me what the different failure modes were and how the "D"rev would take care of what they believed might be a failure mode. I was satisfied with their explaination. So far I'm good.
When I talked to them (SigmaTek) on the phone 2 days ago, I got the same story. They are waiting for FAA review. Personally, I'm done with SigmaTek, going back to Rapco rotary. Piston pump sounded like a good idea and at some point in the future may work out.
If I have another failure, SigmaTek is gonna have a hard time convincing me I need another one of their piston pumps.
They do make a vane pump that uses carbon fiber vanes which won't shatter like carbon vanes. Just a thought.
Here's hoping.
Aircraft Spruce punted me to SigmaTek. Full refund, no questions asked. At least that part was painless.
Well at least they got that down now. Aircraft Spruce wouldn't do anything, Sigmatek said I wasn't THEIR customer, and that's why Amex had to come in and save the day.
Glad to hear they fixed that!
