I used pumps (of KSB make) upto 380⁰C temperature for thermic fluid (Nitrogen pressurised dowtherm system) pumping application. The seals used are metal bellow type and worked fine at that temperature with steam quenching. The pumps have cooling arrangement to bearing housing and pedestal. Cooling arrangement to pedestal is to reduce vibration caused by thermal stresses.

We used Burgman metallic bellow seal with carbon, TC seal combination.
