ABSTRACT:
A regenerative turbine flow inducer for moving lubricating fluid through a seal chamber of a bearing assembly for lubricating sealing surfaces includes a turbine impeller rotated by the shaft and a pair of liners which enclose the impeller, the liners defining fluid inlets on both sides of the impeller, which are communicated with a source of lubricating fluid, and a fluid discharge outlet, the liners containing lubrication fluid supplied thereto and directing the fluid to the impeller as the impeller is rotated, drawing lubrication fluid through the liners. The regenerative turbine flow inducer may be used with double or tandem mechanical seals.
