One of two thousand steam powered pumps built at the turn of the century by the Jeanesville Iron Works Company, the Jeanesville Pump was relocated by Union Oil Company from Georgia, where it had been operating pumping molasses, to California’s central coast. It was purchased and disassembled in Georgia, transported by train to San Luis Obispo, and then taken by twenty-mule team to Shandon. There it was needed to pump oil through a newly constructed Union Oil pipeline carrying crude oil from Central California to the Pacific Coast, where the crude oil could be moved by ship to refineries in San Francisco. Union Oil commissioned the pump in 1910 and decommissioned it in 1986 after more than 76 years of uninterrupted service. Its specifications were approximately 85 tons in weight, a pumping capacity of 1000 barrels per hour, a flywheel weight of 14 tons, a flywheel diameter of 14 feet, a stroke of 96 inches, and steam piston diameters of 26 and 42 inches.
