Roman Bronze Double-Action Water-Pump, Probably 3rd Century CE From Bolsena, Italy, The British Museum, London

This pump had two pistons (a), which were raised and lowered by a rocking-beam (b). The pistons were housed in two cylinders (c). At the bottom of each cylinder was a non-return valve (d).

When one of the pistons was raised, the valve was pushed open and the water rose inside the cylinder. When the piston reached its highest point the valve closed, trapping the water inside the cylinder.
