Gateway Geyser

The Gateway Geyser, which is the tallest fountain in the U.S. and one of the tallest in the world, is an engineering marvel.  Turning it into reality took a combined effort from the two divisions of Missouri Machinery & Engineering:  Hydro Dramatics and The Pump Shop at MME.

The Gateway Geyser is powered by three 800 horse-power pumps, discharging 8,000 gallons of water per minute, at 250 feet per second, with an axial thrust of 103,000 pounds.

The fountain has an automatic system that detects wind speed and lowers the height of the column as necessary to minimize water fallout.  When wind speeds exceed 13 mph, the fountain is automatically shut down. The Geyser normally propels about 1,100 gallons of water weighing 9,200 pounds into the air.

“The heart of the fountain is really the unique six-foot-tall, Swiss-designed nozzle-within-a-nozzle systems that aerates and gives a true shimmering whiteness to the water,” says Bob Korb, president of The Pump Shop at MME, who worked with Hydro Dramatics’ vice president Kerry Friedman to develop the project.  Korb says that the Geyser includes a sea of complex electrical circuitry and 20-inch diameter supply piping.
