Abstract: A pump assembly including an impeller mounted on a shaft for rotation in an impeller casing to move liquid through the casing, the shaft being supported by bearings located in a bearing housing which contains bearing lubricating fluid, a primary seal providing a seal between the shaft and the impeller casing to prevent leakage of liquid from the casing, a secondary seal providing a seal between the shaft and the bearing housing to prevent leakage of lubricating fluid from the bearing housing and a containment vessel interposed between the impeller casing and the bearing housing connecting the impeller casing to the bearing housing and enclosing the primary seal and the secondary seal, the containment vessel having an orifice through a wall thereof for communicating the interior of the containment vessel with a storage container, the orifice being sized to pass liquid emissions from the primary seal during normal pumping operations to the storage container, but to restrict the amount of pumped liquid that is p

Abstract: A universally adjustable hold-down assembly for mounting a drive unit relative to a respective driven unit includes a support member for supporting the drive unit adjacent to a mounting hole thereof, a rod having a head portion located within a cavity defined by the support member and a shank portion which extends through a circular aperture in the support member and through the mounting hole, and a retaining nut which secures the drive unit to the support member, the rod shank portion being sized to be displaceable relative to the centerline of the aperture and the rod head portion being sized to prevent its passing through the aperture.
