Potassium Dichromate?

Potassium Dichromate?

Potassium Dichromate?

(OP)
My company has been asked to recommend one of our specialy hydraulic pumps to pump a solution of potassium dichromate.

I assume that they are referring to a water mixture in the 5-10% range.

What I am looking for:
   1) A reference to compatibility with viton rubber and/or similar materials.
   2) A reference to any of the fluid properties of this kind of mixture (viscosity, density, etc.).

 Thanks in advance to anyone that can lead me to any info.

RE: Potassium Dichromate?

In relation to Potassium Dichromate with Viton rubber, there is no problem, I am assuming the temperature would be around ambient conditions. Viton is still OK at elevated temperatures about 150C, but the life of elastomer will obviously not be as long. Sorry I cannot help you with your second point.
I hope this helps...............

RE: Potassium Dichromate?

Chemical supply companies often include an extensive table in their catalogs showing the compatibility of various chemicals with various kinds of O-ring rubber (& sometimes with metals too.)  I'd call Sargent Welch or Malinkrodt or maybe Cole Parmer and ask if they could send you a catalog.

Meintsi,

If there are still fluid properties you need, email me and I'll send you a table of stuff I found.  Sciguyjim@yahoo.com
