Cross section and details of a pitcher pumpAnimation of a suction hand pump. On the up stroke of the piston the foot valve opens and suction brings water into the pump head. On the following down stroke of the piston the valve on the piston opens up and allows water to flow above the piston. On the successive up stroke of the piston water is pushed out of the outlet.A rural handpump in Belgium.Hand-powered force pump, with an air chamber to smooth out variations in flow rate
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are positive displacement.[1]
Hand pumps are commonly used in developing countries for both community supply and self-supply of water and can be installed on boreholes or hand-dug wells.
