Hand water pump with a pendulum - Veljko Milkovic

Veljko Milkovic - Hand water pump with a pendulum - replicated by Miroslav Zupkov - August 2004, Novi Sad (Serbia) Hand water pump with a pendulum - new manual hand pumping system - 1200 litres per hour (Note: The pipe is placed at the depth of 12 meters, but because of hydrostatic pressure, water level is at the depth of 3 to 5 meters (depending on underground waters, atmospheric rainfalls etc.)) Capacity of 1200 litres per hour is calculated by pumping the bucket of 20 litres per minute - 20 l/min
