A bearing flushing system is provided which enables the clearance between a bearing (156) and shaft (24) to be flushed with water but prevents the backflow of the pumped liquid into the region. The system includes a flow restrictor (166) located downstream of the bearing (156) which presents a second clearance (172) between the shaft (24) to screen out particulates (190). A ring (168) may be provided between one of a pump impeller (15) and the shaft (24) downstream of the flow restrictor (166) to provide an additional backflow restriction.
