Manometer Bubble Pump
A bubble pump. A diy pulser pump shown also.

Solution

Like a gravity siphon that is induced with an air-lift bubble pump. One way check valve located for additional pumping height. The air inlet could be moved closer to the bottom (deep down the well).  The depth of the bubbler determines the pumping height. With the manometer  'loop' the 'effective air-lift pump depth is higher. The air flow volume (at water pressure depth air pressure) controls the volume flow. PV  used for  air supply with aquarium pump or 12V tire inflator . Higher pressure tire inflator for additional water depth(manometer loop height).


The pulser pump shown could be added for shallow ponds.
