A circulating lubrication system for a centrifugal pump, or other rotating equipment
utilizing an oil sump, is disclosed. The lubrication system includes an external
reservoir located distant from the main lubrication chamber, so that lubricating
fluid from the main misting chamber is forced out of the main chamber, cooled and
cleaned (i.e. filtered) in the external reservoir, and thereafter fed back into
the main lubricating chamber. In such a manner, the lubrication system maintains
substantially clean, cool, and moisture free lubricating fluid in the main misting
chamber and reduces the required downtime of the device. Thus, the life span of
the device is lengthened while at the same time production is increased.
