I have this skimmer, its little, and it doesnt use a pump, its the Air venturi type skimmer. I can give you an air pump to use it. Ive never used it, it came from my aunts tank and I dont know how well it works...Needs a good cleaning though.... Not broken or cracked at all...

Its yours if you want it for free, Id like little trades though if you have anything. But if not its yours for free.
