ABSTRACT:
In the representative embodiment of the apparatus of the invention disclosed herein, a circular fluid deflector with a central opening to receive a pump shaft is arranged with a flat transverse face for facing the seal in the pump housing through which the shaft is extended. Fluid-deflecting surfaces are arranged on the deflector including a peripheral rim having an outwardly-diverging inclined surface and one or more annular ribs coaxially disposed between the central opening and the rim which respectively have surfaces facing the shaft seal so that whenever fluids leaking through the shaft seal strike any of these fluid-deflecting surfaces these fluids will be directed outwardly from the deflector member to provide a fluid screen to divert other leaking fluids that would otherwise pass around the deflector and contact adjacent equipment such as the prime mover for the pump.
