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.
