i think my aquamist 2d pump is going bad .

ran it dry by mistake and it was on for a few minutes I honestly dont know exactly how long

now it doesnt make the same sound as it used to , I could always hear when the pump turned on but now it feels like the pressure is alot lower then before I might of burnt up the impeller

so I'm curious do I need a replacement pump ? is there any other pump I can use in its stead ? can i replace the impeller if its bad ?
