Abstract
A pump assembly for conventionally driven centrifugal pumps having a rolling element comprised of product lubricated ceramic or hybrid anti-friction bearings. The ceramic bearings are comprised of ceramic balls and ceramic races, whereas the hybrid bearings are comprised of ceramic balls with races made of another material. The ability of these bearings to perform well with poor lubrication allows the fluid that is being pumped to be used to lubricate and cool the bearings. An alternate embodiment comprises a double suction pump with the same durability and cost saving advantages.
