What is claimed is: 1. A bearing housing for a centrifugal pump, comprising:an outer housing forming a chamber which is structured to retain a fluid for lubricating or cooling the sealing elements of a centrifugal pump; anda separately formed inner housing sized for positioning within said chamber of said outer housing and being axially aligned with said outer housing, said inner housing forming a chamber for retaining a fluid for lubricating or cooling elements of the rotating assembly of the centrifugal pump, said inner housing having a window formed through said inner housing for observation of said chamber formed by said outer housing, the window being oriented at an angle to a defined centerline of the bearing housing, said inner housing further comprising a window formed through said inner housing oriented for observation of the chamber within the inner housing, said window being oriented at an angle to a defined centerline of said bearing housing and said inner housing having means for detachable securement to said outer housing; andan atmospheric barrier drain port extending from a point interior to said inner housing to a point external to said inner housing, said atmospheric barrier drain port being positioned at an angle to a defined centerline of said bearing housing and being positioned laterally to said defined centerline for positioning lateral to a drive shaft positioned through said bearing housing.
