Aero Advantage Dual Vacuum Pump

Recommended Posts

I have one of the subject pumps installed on my Ovation.  Both sides of it failed simultaneously on a flight this past weekend.  So much for the reliability of two pumping chambers.  I guess that's part of why the company went out of business.  Anyway, does anyone know where I might find a replacement?  Maybe my best option is to just put one of the original pumps back in its place.  Anyone know the part number/type of pump I'd be looking for if that was the case?  Thanks!

That's the same pump I had on my old 172. I received a notification to replace it some years ago. Because of a design flaw that would allow both of the chambers to fail simultaneously, (as you now can attest to) the pump was pulled from the market and the company closed. It was a great idea with a poor design.

You will have to go the route of a different kind of pump.
