In my experience, Lotus is very inexact when it comes to the pulleys on their water pumps. The later Lotus pumps that have the weirdo, enormous pulley are nightmarish at best, I won't even rebuild those anymore. It's like a crazy person designed it. The only way to mitigate this is to put the pulley in a lathe and hone off a bit of metal from the V section to try and even it out. On the pump itself, if the shaft is perfectly straight (you usually can't tell by eye), then there isn't much you can do.
