Hand pumps are water pumps powered by the movement of human arms. They are used for lifting water from low-head cisterns and wells, and some types can force water at a pressure to suit domestic applications. There are different classifications, including lift type and force type, with force type pumps further divided into single-acting and double-acting. Hand pumps consist of components like a pump head, handle, plunger, cylinder assembly, suction inlet, and outlet. They are designed to be manually operated and are crucial for water supply in many areas, especially in rural settings and developing countries. The manufacturing requirements specify materials such as cast iron or better for various parts, and performance requirements include the ability to lift water to certain heights.
