The traditional lower bearing is based on a non-rotating stub shaft that is rigidly mounted to the bottom of the inlet and a bronze bush sleeve bearing, mounted to the lower end of the screw pump, that is rotating around the stub shaft to ensure that eventual wear will occur evenly distributed. A very small amount of grease is constantly pumped into the bearing by a grease pump that is installed at the top.
Spaans Babcock ERGO-guard gives the screw pump and lower bearing maximal protection by using guards/shrouds around the lower bearing. By using this cover the possibility of items such as rags, ropes, cables and other debris wrapping around the bearing will be eliminated.
