The #pulser-pump depicted here are not quite just #airlift pump #mechanisms; they’re sort of like a geyser pump in that the riser pipe with the output water reaches below the roof of the compression chamber to dip into the water when the water level is high enough, guaranteeing that the pipe will receive pulses of water even if the air and water fully separate in the chamber. This page credits Charles H. Taylor (who built the Ragged Chutes trompe) with inventing it in 01910, though Practical Engineering claims Cáceres reconstructed it in 01911 from 18th-century descriptions of a miraculous pump at the Alhambra.
