Abstracts: An objective of present work is to design a pendulum-lever mechanism to operate hand pump. A pump operation with the help of a pendulum-lever mechanism require minimum of human strength in comparison to present classic hand water pumps. Hand water pump with a pendulum - provides alleviation of work, because it is enough to move the pendulum occasionally with a little force to pump the water, instead of large swings. Using the minimum of human strength in comparison to present classic hand water pumps enables efficient application in irrigation of smaller lots, for water-wells and extinguishing fires even by old people and children. The advantage of this mechanism compared to present hand pump solutions are: less force to start the pump, less human effort, both arms can be used to fetch the water.
