ABSTRACT:
There is disclosed a pressure extraction pump system for recovering liquid hydrocarbons from contaminated ground water collected in a well. The pump system includes a pump with a pump vessel and an open top sleeve extending above the pump vessel for skimming the upper portion of the liquid collected in a well bore. The pump also includes a liquid level sensing device for sensing the level of the liquid in the sleeve and activating a pumping cycle. The pump also has a quick closing intake valve.
