V Madhushoodanan of Kerala has developed a miniature submersible water pump. This 3 cm X 2.5 cm pump is indeed tiny and weighs mere 45 gm. However, its 3 mm diameter pipe can lift water up to 2.5 feet! Using a 12 mm diameter copper leaf impeller, this pump requires 3 V to 12 V DC depending upon the discharge ranging from 200 to 800 ml per minute. Mr Madhusoodan has studied up to class six and has made it from commonly available components including a motor from a walkman audio system. This pump has been run for an hour and tested by the District Water Authority, Kerala. It can effectively be used as submersible pump, for aquariums and in chemical processes to pump liquids at various levels.(Appro TEC has developed a very small, leg operated pump with one piston and one cylinder www.approtec.org) |
