ABSTRACT:
An above ground--below ground pump apparatus for use in pumping underground fluids to the ground surface. The pump apparatus includes an above ground pump for alternately propelling fluid into a well casing surrounding the pump apparatus and discharging underground fluid therefrom and a second pump is mounted underground within the well casing at a pre-determined location. The second pump includes alternately movable pistons which draw in fluid from the well casing and discharge the fluid through conduits to the ground surface. An anchoring device is attached to the exterior of the first and second conduits for anchoring the second pump at a pre-determined position within the well casing.
