For PV direct from that depth, it's got to be positive displacement... perhaps a jack pump, though replacing a foot valve could be a big job in itself. There is the trick of drilling a small hole low on the pipe so while pumping the volume far more than compensates, but leaves the pipe empty between pumping.
