Why the vibratory pumps, which are commonly used in Brazil, are not used in rural sector as they can be cheap and efficient ?
Is there any company in india who can supply the vibratory pump which operates at within our utility power supply? Information regarding vibratory pumps can be had here : http://www.kolmus.com.pl/english.htm
