This extremely simple pump was made of cast iron, and had no pistons, rods, cylinders, cranks, or flywheels.
The air chamber is for the purpose of preventing water-hammer in the suction pipe.The pump ran automatically without attendance.
It was praised for its "extreme simplicity of construction, operation, compact form, high efficiency, economy, durability, and adaptability".
Later designs were improved upon to enhance efficiency and to make the machine more accessible for inspection and repairs, thus reducing maintenance costs.
