Abstract

See full text

A liquid level control pump especially well adapted for use in landfill wells is disclosed. The pump makes use of a pump casing, a discharge tube, a control rod, first and second check valves, a float and a pivoting lever assembly for controlling the application of a pressurized fluid from an external pressurized fluid source. In one aspect the float may include a through slot which allows the control rod to pass therethrough and which helps to reduce the chance of the float hanging due to an accumulation of solids between the control rod and the float. In another aspect a removable and replaceable discharge tube sleeve may be included.
