This is a plastic impeller on a brass hub. If the impeller is loose it is probally cracked or overheated and melted, ether way you will have to break the impeller off of the hub then you will need to break hub loose from shaft. You can do this by putting pump in a vise and putting a pair of vice grips on hub and giveing them a sharp hit in a counter clockwise direction. you will need to replace the seal and impeller and should check to be sure than you can get these parts before you start.

Yes, If it goes together it will come apart. If it is the one I'm thinking of if you take the base apart there will be through bolts that run through the whole pump, remove these I want to think there are some that are short and these hold the base to the motor but they may be behind the impeller. Be warey as I'm not sure. But once the through bolts are out you should be able to carefully remove the top. Some have very frail gaskets here so be gentel. Once you have the top free there will be a compression nut holding the cord before pulling cord through use a light sand paper to clean the cord so the part you pull through will be fresh enough to seal. Don't lube the cord this will keep it from sealing. Pull it hrough and make your repair and put it back together the way it came apart. Use a sharpie to mark the top and housing as you take it apart. When finished loop some cord through pump handel and tie it off so this takes the weight in the future to keep from having the same problem again. good luck
