Pump material as per NACE spec

Pump material as per NACE spec

(OP)
Folks,
I have PD pump to transfer crude to pipeline, (it is mid-stream); Assuming it is sour liquid shall I consider upstream and use NACE 0175, instead of NACE 0103?
Crude analysis specifies total sulfur only and TA value. It specifies no H2S. Should I still consider sour liquid and use NACE spec for material selection?

What material types NACE generally requires for pumps in sour service? Is it covering trim only? Casing? impeller, etc
