Elephant Pumps
The Elephant Pumps are used for getting clean water. To make these pumps is quite simple and it only takes about four hours.
Now, what makes the Elephant Pump so different from the other popular low maintenance pump is that these pumps are made way diffrent. There depth is 80-100m. High durability, low-maintenance vs. <40m depth, simple design, cheaper.
These pumps are made for schools. The Elephant Pump yields about one litre of clean water every second for an average well depth of 20 metres.”
