Mohamed Lamine Camara

African Inventors

November, 2009
Mohamed Lamine Camara is an engineer in mechanical engineering and professor at the Gamal Abdel Nasser University in Conakry. The Guinean is best known for having produced a hydraulic pump which significantly minimizes the physical effort exerted on the lever arm of the well regardless of the well's depth.

On average, one usually needs to exert a 2 or 3 kg pressure on the lever arm of conventional hydraulic pumps to lift 5 kg of water. With Mohamed Lamine Camara's pump, a pressure of 1 kg suffices to lift 10 kg of water.

Another characteristic of Mohamed Lamine Camara's hydraulic pump is the triple-filter system. It is also possible to adapt a bacterial filter on the pump. A bacterial filter is made up of sand, gravel and coal. This pump is also equipped with a system that removes particles that have managed to hang on the inner surface of the pumping system.

Mohamed Lamine Camara would like his invention to be mass produced. But the conditions that have been proposed by some manufacturers are not always to his advantage. Production costs at the local level remain high given the financial situation of this professor. Indeed, the production cost of 12 prototypes is about €13,000 (8.5 million CFA francs) or approximately €10,083 (710,500 CFA francs) per unit. Building a plant in Africa for mass producing this pump could certainly be an interesting approach to look at.

Mohamed Lamine Camara won the gold medal at the 26 International Exhibition of Inventions of Geneva, the gold medal of the World Intellectual Property Organization (WIPO), the gold medal at the Brussels Eureka Fair and received the 3 Grand Prix at the African Invention and Innovation Exhibition in Libreville. Mohamed Lamine Camara's Pump is patented since 1996 with OAPI (Organisation Africaine de la Propriété Intellectuelle or African Intellectual Property Organization).
