摘要： The present disclosure relates to a modular fluid pump system for configuring a fluid pump in a selected one of first and second configurations. The system may have a first pump casing with a first diameter, and a second pump casing with a second diameter smaller than the first diameter. A tubular frame may be included along with a first float having a first diameter positioned over the tubular frame for sliding longitudinal movement along the tubular frame. The first pump casing may be used to configure the fluid pump in the first configuration, to thus provide a first degree of clearance between the first float and an inner surface of the first pump casing, or alternatively the second pump casing may be used to configure the fluid pump in the second configuration, which provides a second degree of clearance between the first float and an inner of the second pump casing.

摘要： 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.
