I myself have started pumping, and I have straight barbells that are medical grade steel. So far, I've had no issues, but I've had mine in for 2 years haha, I'm not really sure if freshly pierced nipples would go well though, I think I would let them heal a bit first. Maybe wait a month after the piercing, and try it? Hope that helps
