Hand water pump with a pendulum is very simple solution for pumping water. The advantages of this invention compared to present hand pump solutions are less force to start the pump, elders and children can also operate it 2 without any fatigue, since maintaining the oscillation of the pendulum does not request any special training or dexterity. Pendulum pump can be used to supply water for human needs, fire extinguishing, irrigation and agriculture by disabled or handicapped persons as well as women in areas with less manpower, water supply and electricity, rural areas and undeveloped countries.

3. INTRODUCTION
Water is one of our basic needs. Water pumps move water from point a to point b
for centuries. Modern pumps require electricity and ancient pumps require more
efforts to operate. Therefore Veljko Milkovic came with the concept of pendulum
based water pump.
