Chain-based rope pump - GIF

Depending on how well the leather cups fit the tube judging by the diameter and the estimated distance between the cups allowing for the volume of the chain it looks like about a liter per piston Now deep is the well ????? who knows how high the water table is ??? again we don't know but he could be pumping around 50 to 60 liters per minute, not bad.
