ABSTRACT:
An apparatus for removing excess material from a container with a follower plate pump assembly comprising providing an air bladder, disposing the bladder within the container, connecting the bladder to the air source, and inflating the bladder via the source when the follower plate has reached a point in the container where it no longer has the ability to pump material, the air bladder forcing material up to the follower plate. A pump removes material from the container. The apparatus further includes an anti-fouling plate coupled to the bladder which prevents the bladder from interfering with the pump.
