ABSTRACT:
Centrifugal pumps for handling acids or slurries incorporate a ball bearing assembly as the force-responsive governor to control opening and closing of a fluid path leading from the expeller region into a seal, the seals being composed of hard, low-friction sealing materials for handling acids and of resilient materials for handling slurries owing to the solids content in the slurries.
