Designed to help uplift rural life in developing countries around the globe, the pump has been patented in more than a hundred countries earlier this year.
The Ezee Pump is operated by using various configurations of separate attachments to suit the strength or number of operators: It can be pedalled by an adult male, or using a cranking mechanism, two women can operate the pump by turning the handles. When a second pedalling mechanism is attached, two teenage children can pump in tandem.
Cost of the Ezee Pump and a single attachement is around $600.The pump can also be powered by electric motor, petrol or diesel engines and solar panels.
Its simple operation and movability sets the Ezee Pump apart from similar pumps which are generally heavy and very difficult to operate manually, according to company spokesman Brian Servant. “Our pump has two large wheels on which it can easily be rolled to the pumping location.”
For operation the pump is turned into a vertical position. It can be used to raise water to a supply tank on a stand and by multiple pumps, can increase the height accordingly by pumping from one pump to another using water from the 160 litre reservoir in the lower wheel of each pump.
Another advantage is the fact that the pump has no impellers within the water flow which can be damaged, while a 50mm suction hose together with the pipes in the machine allows water to flow freely.
The pump is designed to pump readily available surface water with grit or sludge within 9 metres below the pump. It can produce 3 litres water per second on flat ground, 2 litres per second at a height of 6 metres and 1 litre per second at 9 metres.
“One pump, working continuously during normal daylight hours, raising water from a source 6 metres below at a rate of 2 litres per second, could provide 8,640 people with 10 litres of water per day,” says Servant.
It is also suitable for water transfer into dams, storage tanks, irrigation canals or directly onto hydroponic areas.
The pump is driven at 270 revolutions per minute, which is considered to be slow for water pumps and should therefore extend its life. The pedalling and cranking mechanisms consist of standard BMX bicycle parts which are easily obtainable throughout large parts of the world.
