Ceramic Pump Seals:

    Ceramic - Generally a 99.5% aluminum oxide offering excellent wear characteristics due to it's hardness. It is chemically inert and can be applied to nearly any product. Ceramic cannot however handle the thermal shocks that Ni-resist or 17-4 seats can.  They will also shatter like a plate if dropped on concrete.

    Ceramic: 99.5% pure aluminum oxide (alumina) is preferred. Lower purity grades (typically 85%) are available, but are more subject to chemical attack and thermal shock.
