Titre : hand pumps for village wells Type de document : texte imprimé Auteurs : Spangler, C. D. Mention d'édition : Volunteers in Technical Assistance Editeur : Volunteers in Technical Assistance Année de publication : 1975 ISBN/ISSN/EAN : CI-04919 Note générale : Manually operated pumps of various designs are used in most countries to lift relatively small quantitics of water from wells for either family use and/or irrigation. There are two general types of pump, piston and diaphragm. Both types have two cheek vakues, either on each side of the diaphragm. Or one below the piston and the other incorporated into the piston. The diapragm pump will pump the hargest quantity of water, but can only operate when the water level in the well is within about 15 feet or less of the pump. It is a suction type pump. The piston pump may either be operated as a suction pump or if the water level is more than 20 feet selow the surface, the psiton can be installed below the lowest water level and thus become a deep well pump.
