Persian Wheel

Archimedean Screw

Dragon-Tooth Pump

Washer Pump

Axial flow pump

Quasi-centrifugal pump (inverse sprinkler)

Rope pump

 

RECOMMENDATIONS

Of the "Village Technology" solutions, the shadoof, the cableway-and-bucket, and the bucket-and-chain pumps appear to me the most suitable.

Of the "off-the-shelf" solutions, the piston pump and the semi-rotary pump appear the most useful.

The vane pump and the axial flow pump could be feasible innovative solutions.

For the urban or rural craft workshop level, the locally-produced piston pump is possibly the best solution.
