You don't need a new pump
Seriously you probably sucked some crud up from the bottom of the tank. I did this when mine was brand new and have several times since. There were plastic shavings in my tank and that clogged the screens going into the pump. I don't recall exactly how I got mine apart but it wasn't hard to do. I would first make sure the input side is clear of obstructions then I would pressurize the pump with the output line off and make sure it is pumping clean. I think I even had plastic shavings in my pump at one point and that allowed the pump to spit those pieces out. I don't know that is what your problem is but it would be a good place to start trouble shooting.
