ABSTRACT:
A bearing flushing system is provided that enables the clearance between a bearing and shaft to be flushed with water but prevents the backflow of the pumped liquid into the region. The system hereof includes a flow restrictor located downstream of the bearing which presents a second clearance between the shaft to screen out particulates. A ring may be provided between one of a pump impeller and the shaft downstream of the flow restrictor to provide an additional backflow restriction.
