Abstract
A pumping unit operable to pump water has a longitudinal pumping unit axis. A pump shaft engages shaft bearings in a pump shaft housing. A drain conduit includes a drain conduit inlet segment, a drain conduit ascending segment, and a drain conduit terminal segment. The drain conduit inlet segment has a longitudinal drain conduit axis disposed at an obtuse angle to the longitudinal pumping unit axis. The drain conduit ascending segment is disposed at an obtuse angle to the drain conduit inlet segment. The drain conduit terminal segment is disposed at an obtuse angle with respect to the drain conduit ascending segment and is disposed at a level above the shaft bearing. Accordingly, backflow water flowing through the drain conduit terminal segment, the drain conduit ascending segment and the drain conduit inlet segment, respectively, flows into the pump shaft housing to contact and cool the shaft bearing.
