ABSTRACT:
A high temperature, centrifugal pump includes a thermally isolated and dynamically air cooled shaft seal. Carbon graphite insulators formed of plural elements juxtaposed together (46) insulate the seal assembly (34) from the pump housing (16). A hollow drive shaft limits heat conducted from the impeller during operation while a fan (56) forcibly flows air past the seal assembly to conduct heat energy away from the shaft seal. The insulator (46) reduces heat energy conducted to the seal assembly (42).
