Hi Everybody, Does somebody know

Hi Everybody, Does somebody know

(OP)
Hi Everybody,

Does somebody know what the "DR" code in Sundyne materials of construction refers to?
Specially when the wet parts e.g. diffuser, pump casing,etc. are concerned, for instance diffuser P/N: D02NF00DR547ABH
is it addressing to Duplex/Super Duplex?

Thanks in advanced for your comments.

Regards,
Pejman.

RE: Hi Everybody, Does somebody know

Have you contacted the OEM?

RE: Hi Everybody, Does somebody know

It could mean "dressage" (French word, assuming NF stands for French Normative..) for steel.
But this would apply generally to plates (so possibly in the context of a fabricated technology).
In your case, you mention components which may not be fabricated (e.g. casted, forged, etc). Check if DR applies to fabricated parts, if yes then maybe it could be the signification, otherwise discard it completely.

Best is to contact OEM in any case.
