Looks like its probably ok still.
Is there any cracks in it when straighten out the fins?
But its out, why not replace it now instead of haveing to take it apart again later.
Maybe it will work, but????? Why not replace it, it?s cheap and sooner or later it will stop pumping, then you may overheat the powerhead. That costs alot of dollars.
It is good practice and preventive maintenance to replace it, however, that impeller is still good. Notice how there is no wear at all at the vane tips and the center mold lines are still showing on all the vanes. It may not have been used at all or has very little running hours on it. The vanes are bent because they have taken a "set" from sitting inside the pump. This is normal. Save it for a spare.
