Abstract
A buoy assembly for use with a pumping system to pump liquid and debris from a flooded shaft or well or any such structure with appreciable depth is provided. The buoy assembly includes a proximal tube that can couple to an end of a hose coupled at an opposite end to the pumping system. A buoy is coupled to the proximal tube that provides the buoy assembly with buoyancy that allows the buoy assembly to float on the liquid in the shaft. The buoy can have one or more aeration ports that can be selectively opened (by removing a plug therefrom) to allow airflow therethrough into the buoy. The buoy assembly also has an adapter socket with feet that define vents therebetween to allow passage of debris via the vents into the buoy. Flow of air into the buoy via the aeration ports facilitates lift of liquid and debris through the conduit during a pumping operation.
