"The operation of the force-pump is similar to that of the suction-pump. The outlet-valve generally opens from the cylinder, the piston being made solid." — Avery, 1895

"In the forcing-pump atmospheric pressure plays but a small part. There is no valve in the piston c, but the water raised through the suction-pipe a, and the valve g, is forced by each depression of the piston up through the pipe e e, which is furnished with a valve to prevent the return of the fluid." — Wells, 1857

"The common pump consists of a hollow tube, the lower part of which, descending into the water, is called the suction-pipe, and the upper part, b, the battel or cylinder; of a spout, s, at the top of the cylinder; of an air-tight priston, which works up and down in the cylinder; and of two valves, both opening upwards, one of which, g, is placed at the top of the suction-pipe, and the other, p, in the piston." — Wells, 1857

"The lift pump or suction-pump consists of a cylinder or barrel, piston, two valves, and a suction pipe, the lower end of which dips below the surface of the liquid to be raised." — Avery, 1895

"The suction pump uses suction, water pressure and one-way valves to suction water from a well or other source, and to expel water through A." —Hallock 1905

A Siphon can be started by inserting one end of a tube in the liquid and sucking at the other end. It is more convenient to apply suction by means of a side tube as shown to prevent the liquid from entering the mouth.

The suction-pump consists of a clindrical pump-barrel traversed by a piston, and communicating by means of a suction-tube with the water in the pump-well.
