The International Exhibition: centrifugal pump by Easton, Amos, and Co... 1862. Creator: Unknown
The International Exhibition: centrifugal pump by Easton, Amos, and Co. - from a photograph by the London Stereoscopic Company, 1862. The machine...consists of an Appold's pump, placed in a case or tank of cast iron, on the top of which are fixed two high-pressure expansive condensing steam-engines, each of the nominal power of twenty horses, giving motion to the vertical spindle of the pump by means of a bevil-geared flywheel working into a pinion. The water is raised from a cast-iron tank, 12ft. deep, partly sunk in the ground, and containing 24, 000 gallons, and is delivered over the edge of the upper tank in a sheet 42ft. wide and 10in. thick. The quantity raised as computed by Mr. Beardmore's hydraulic tables (the best authority on the subject) would be rather over 180 tons per minute...the water in the large tank is made use of for the purposes of condensation, so that the full power is got out of the steam...In the colony of Demerara, which is a low-lying fiat country, dependent entirely upon artificial means for keeping the land dry during the tropical rainy season, a great number of these pumps have been erected...[The pump is] especially suited for emptying docks, or for any purposes where tidal influence has to be encountered'. From "Illustrated London News", 1862

EDITORS COMMENTS
This photograph, taken by the London Stereoscopic Company in 1862, showcases an impressive centrifugal pump designed by Easton, Amos, and Co. The engineering marvel consists of an Appold's pump enclosed in a cast iron tank, with two high-pressure expansive condensing steam-engines, each producing approximately twenty horsepower, situated on top. These engines transmit power to the vertical spindle of the pump via a bevel-geared flywheel and pinion. The water is drawn from a 12ft. deep cast-iron tank, holding 24,000 gallons, and is discharged as a 42ft. wide and 10in. thick sheet over the edge of the upper tank. According to calculations by Mr. Beardmore's hydraulic tables, the pump is capable of raising an impressive quantity of water, surpassing 180 tons per minute. The water in the large tank is utilized for condensation, ensuring maximum efficiency from the steam. In the colony of Demerara, where the terrain is flat and relies entirely on artificial means to keep the land dry during the tropical rainy season, numerous instances of this pump have been erected. Its unique design makes it particularly suitable for emptying docks or any purposes where dealing with tidal influence is necessary.
