pinging sound coming from the pulley mounted to water pump. on 1998 Mercury Sable

Is this a tensioner pulley or just part of the water pump and can I just replace pulley or do I need a pump? Can a bad surpentine belt cause the noise. The more RPMS. the louder and faster it gets.How long will pump last if it is bearings going out in pump?
