Is this an aftermarket pulley? Why do you assume the power steering pump caused this? Just asking. Also inspect all pulleys rotate and inspect them all the way around for and defects, cuts, anything else if they are fine then make sure you are routing the belt correct and its seated in the groove correctly.
