Problems associated with pumping 98-99% Nitirc Acid

[pumpking]

We have recently been asked to recommend a pump for roadtanker unloading 98-99% Nitric Acid to a bulk storage tank, and seeked assistance from one of my French colleagues who has vast experience in such applications - only problem is i cant understand French so dont fully understand the problems associated with pumping this high concentration Nitric.

He was saying that one of the key concerns was the NPSHa in the system as the Nitric pull out into gases ? We are handling the product with PFA lined pumps successfully, but it is the theory behind the system implications that i do not understand 100%

Can anyone assist in this please ??
