Well, typically, if the guy thats selling you the tank has had it up and running, hell have a pump. If not, than yes, youll need to buy a pump. There are tons of different choices when it comes to these, depending on your $$$ situation. You can get something sufficient for around $100 or something superior and that will last for 10+ yrs for under $300.
