“Humphrey pump “seems to be the most robust motor driven water pump. Nearly 100 years old pump is still in working condition in Australia.
In my second project I have tried to “reincarnate” the very old idea. With minimum of moving parts and filled with available biomass (wood, straw, etc.) this system meets almost all requirements of both maintenance costs and price.
I am sure that 100-years old technology may be reproduced and improved in India without big problems and investments.
