Double-acting Force Pump

“A double-acting pump of the piston pattern is shown [here]. Such a pump has two sets of suction valves and delivery valves, one set for each side of the piston. With the piston moving in the direction of the arrow, the pressure of the atmosphere forces the water up the suction pipe P into the left-hand end of the pump cylinder, the left-hand suction valve opens and the left-hand delivery valve is closed...The water now flows up the delivery pipe P’.” —Hallock 1905
