I imagine that you should be able to trap out all the F2 before it gets
near your pumps.  We use KBr @150c.  At least that is what we do.
I think I would be more worried about what happens to the pump if it gets a
burst of F2 than the oil.  The reaction between halides and organics can be
pretty exothermic from what I hear.
