| David Arnfield posted The Holly high duty triple expansion pumping engine at the Spring Garden pumping station philadelphia. capacity 30,000,000 us gallons per 24 hours Allen Phillips: The steam was expanded three times in progressively larger cylinders at progressively lower pressures. The Liberty ship engine had cylinders 24", 37", and 70" in diameter, all with a 48" stroke. Steam (mildly superheated) entered the HP cylinder at 200 psi, and exhausted into the IP cylinder at around 60 psi. That steam exhausted into the LP cylinder at around 10-15 psi and exhausted into the condenser at 25 1/2 inches/mercury vacuum and a temperature around 130degrees F. |

In 1845, Spring Garden was a town that was independent of Philadelphia. This pumping station also supplied water to Northern Liberties. "The districts and their system were annexed by the City of Philadelphia in 1854. At the time of annexation Spring Garden was the ninth largest city in the United States and Northern Liberties was the eleventh largest." [WaterworksHistory]
