Re-read your signature, buddy.
Pedanticism doesn't advance knowledge.

I was simply trying to get some idea of the output of the pump.
Perhaps I would have been wiser to ask for the rating
(in the unlikely event that it is listed)
in litres per minute.

Thanks for the link, David.
I can see from the description
that this pump is designed to protect
a single hobbyist's aquarium.
Though I certainly agree that any aeration is better than none.

That's a good price for a back-up
that comes on line automatically.
