SEALED STEADY BEARING ASSEMBLY FOR NON-METALLIC VERTICAL SUMP AND PROCESS PUMPS

摘要

A bearing assembly for radially supporting a drive shaft of a pump such as a vertical sump and process pump. The bearing assembly has a bearing housing, a bearing having inner and outer surfaces, a bearing housing for holding the bearing; seals disposed in the housing for retaining a lubricant pumped into a space formed between the inner surfa ce of the bearing and the drive shaft, and at least one water jacket disposed about a portion of the outer surface of the bearing. The water jacket circulates cooling liquid that contacts the outer surface of the bearing and carries away heat conducted through the bearing due to rotation of the drive shaft during operation of the pump.
