I also have water pump pulley with the DV designation instead of BV. I thought it was a misstamp, when I purchased it years ago. Is it an update for the Z/28? Is it a later pulley? Was there any differences between the two? Possibly a redesign?

My understanding is both are correct and factory installed.
