Do i need a new water pump because pulley broke?

I have a 1992 cutlass ciera s V6, the pulley that is attached to the waterpump that is turned by the belt broke off. Not sure how to fix this. Would a new water pump come with that part on it or is that pulley part separate from the pump? Also Where should i go to get that part?Do i need a new water pump because pulley broke?water pump will come with pulley - after many years, the likely hood of getting the old one off is remote
