Hi Kevin,
Others have already pointed to this. I'll just chime in my support. A good, old fashioned "Jack Pump" would be my choice. It's a simple, submerged, positive-displacement pump that sits at the bottom of the discharge pipe. Because it operates as a discharge-lift, vs a suction-lift, you can pump from much greater depths (Total Dynamic Head).
Further, these old hand-operated jack pumps can also be operated by the old fashioned windmills, with a crank on the turbine axis that oscillates a rod (the "sucker rod") that's attached to the pump.
