RE: HVOF powder for Impeller
My guess is that MDEA is probably intended to mean: Methyl Diethanolamine in this instance. I would guess that this pump operates in a chem/petrochem refinery type environment. MDEA is a common sweetening agent for these types of facilities.
That said, I don't know enough about the behavior of the chemical or the pump application to give this post more meaning. A "solution" doesn't really provide much meaning either. Presumably you are referring to an aqueous solution, but it could also be alcohol or some other hydrocarbon solvent, and concentration may play a role in suitability as well.
In addition there are concerns about the form of wear you have encountered in the pump. If this is cavitation wear, then the recommendation will differ from sliding abrasion or corrosion/erosion. Can you provide finer detail?
