Authentic Miller Dunn Shallow Water Dive Pump

Hard hat diving pump, circa 1910. Genuine shallow water diving pump made by the “Miller-Dunn Co. Miami Fla. and a number 1” as cast on the tops of the twin cylinders. This heavy duty pump is the “No. 1” model dive pump that was used primarily with the Style 1 and Style 2 “Divinhood“ brand dive helmets. It consists of a cast iron rocking beam attached to brass rods activating dual pistons. Valves on each cylinder direct air to an outlet via a hard rubber hose which connected to the diver’s air line. The pump is now mounted on to a small section of teak grating. Measures 14 inches long by 6 inches wide on the base, 16 ½ inches high and weighs 30 pounds.
