ABSTRACT:
There is provided a dual pump floating layer recovery apparatus for pumping a floating layer of contaminant out of a well. The apparatus comprises an upper pump and a lower pump. The lower pump creates a cone of depression which increases the amount of the floating layer within the well. The upper pump pumps the contaminant from the well or cone of depression. The upper and lower pumps preferably are gas-actuated pumps. The lower pump preferably includes an automatic switching device to activate the lower pump upon sensing a predetermined amount of fluid within the pump. A gas conduit interconnects the actuation chambers on both pumps such that when the lower automatic pump is provided with pressurized gas, the upper pump is simultaneously provided with the identical pressurized gas. Upon deactivation, both pumps relieve the activation pressure through the lower pump.
