pendulum based water pump

Hand water pump with a pendulum is a very simple solution for pumping water. It provides alleviation of work, because it is enough to move the pendulum occasionally with a little finger to pump the water, instead of large swings. Work is alleviated because easier, long-lasting and effortless use of the hand water pump has been enabled.

Input energy for starting the process of pumping, in form of occasional pushing of the pendulum, is much less than with typical hand pumps. Whereas typical hand pumps require significant effort and an average person can use the pump continuously only for several minutes, the pendulum pump needs the minimum of the effort, because it is only necessary to swing the pendulum and maintain the oscillation for several hours, without any fatigue.

The advantage of this invention compared to present hand pump solutions are: less force to start the pump, less water consumption, both arms can be used to fetch the water.

It is possible to pump out a 1200 liters of water per hour, without any fatigue and continue with the pumping. Both arms are free for fetching water, and both elderly and children can use it, since maintaining the oscillation of the pendulum does not request any special training or dexterity.

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.
