ABSTRACT:
A pump comprising an elongated housing adapted to be positioned in a landfill gas well. The housing has a peripheral wall, an interior chamber and apertures in the peripheral wall leading from the exterior of the housing to the chamber so that liquid can flow from the well into the chamber. A pressure responsive valve member is mounted in the chamber on the peripheral wall and extends across the apertures. A discharge conduit extends from the chamber to a location above the housing. When the liquid level in the chamber rises to a predetermined upper level, gas under pressure is supplied to the chamber. The gas under pressure causes the pressure responsive valve member to close the apertures and it forces the liquid out of the chamber through the discharge conduit.
