Can a power steering pump goes bad if there is air in the system?

(2002 Subaru Outback)
My 2002 Subaru Outback just had a power steering pump replaced along with p/s fluid and hoses to and from the p/s pump about 6 weeks ago. The noise from the power steering system got worse instead of better. The car was subsequently taken to a Subaru dealer where I was advised the power steering pump must be replaced along with the idler pulley, bolt, washer and serpentine belt. When I mentioned the p/s pump was 6 week old, I was told air in p/s system can quickly damage the p/s pump. Is this correct?
What seems to make the problem better or worse? Turning steering wheel when back up or turning sharp corners
How long have you had this problem? 7 weeks

I have never experienced air in the power steering system causing premature failure of a power steering pump. I suppose anything is possible.

It is more likely that the replacement pump may not have been of sufficient quality, and hopefully has a warranty that you can utilize to replace it.

It is curious, however, that all these other parts need to be replaced now also, which makes me wonder what other information may be missing from the symptom, conditions and findings?
