Please note that we are going to use following seal combination for centrifugal pumps,
1)Feed pump will have double mechanical seal with Sic / Sic IB and C/ Sic as OB.
2) Distillate pump of MEE will have double mechanical seal of  C/Sic and C/ Sic.

3) Distillate pump of ATFD will have  C /Sic seal.

What should be the elastomer part for these mechanical seals  ?
