Lifting Pump

“In some cases it is desired to raise water higher than it can be forced by the pressure of the atmosphere into the chamber of a simple suction pump. To accomplish this the pump chamber with its bucket and valves are set at a distance above the supply not exceeding that to which the air will successfully force the water. A closed pipe, P’, called the delivery, or discharge, pipe, is then led from the upper part of the chamber to the point where it is desired to deliver the water.” —Hallock 1905
