Abstract
A rotary pump includes an impeller mounted on a shaft 12 supported for rotation in bearings. A bearing and bearing casing assembly 26 proximate the impeller is prone to ingress of undesirable matter. A shield assembly 40 includes the shaft 12 and a shield 40 rotatable with the shaft and positioned intermediate the impeller and the bearing assembly 26. The shield comprises an integral, moulded, disc 42 and composite rim 44, which includes a lip 50 having an inwardly proud beading 52 normally touching an outer periphery 34.1 of the bearing assembly. A cowl 48 surrounds the lip with clearance when the shaft 12 rotates. The beading 52 dilates under centrifugal force to provide running clearance.
