Splicing in a different pump for Tunze ATO?

It won't work. You would need a relay switch to convert the DC voltage to AC. Tunze sells such a device or you can DIY one.

Roger had this to say "The osmolator now uses 11V we have used 9V-12V through the years. The pump lasts longer and uses less power at 9V but with 12V it pumps more and typically in the mA ratings we need it is easier to find 12V power supplies."
