ABSTRACT:
A protection system for pump shaft bearings which are exposed to water or water combined with various particulate material when the pump and the shaft or a portion thereof are immersed in the water or combined water and particulate material which is being pumped. The protection system includes an enclosing chamber associated with the bearing or bearings supporting the pump shaft which are immersed in the material being pumped with the enclosing chamber being filled with grease exiting from the bearing so that the pressurized lubricant to the bearing will maintain the enclosing chamber filled with grease to exclude the material being pumped from the enclosing chamber and bearing assembly disposed therein. The enclosing chamber is associated with and connected to a conventional flanged shaft bearing and includes grease seals associated with the pump shaft to maintain the interior of the enclosing chamber in isolated relation to exterior environmental conditions.
