pump seizing up

I recently moved into a home w/ a ~2000 gal pond. The pump won't restart after I turn it off. It buzzes so I don't suspect an electrical problem. A sharp blow with a hammer to the pump housing causes it to kick back into action. (don't ask how I figured this out) and it operates normally until I turn it off again. Is my pump on its last legs? how many more hammer blows can it take? Is this worth repairing or should I plan to buy a new pump. I'm guessing its about 10 yrs old. A jacuzzi LR 1/2 hp, 2-spd pump.

thanks for any insight.

I'm not familiar with your pump but in general it does not take much dirt or crud to keep a motor from starting (turning). If you can take the pump apart and give the pump section a good cleaning it may help. You may have some mineral deposits or scum that is causing just enough drag to keep it from starting. It is also possible that your motor is on the way out.
