INTRODUCTION 1999

This pump was built in 1978 and this report was written in 1979. I had one refusal from ITDG to publish it then and stupidly gave up instead of persevering. Recently I see that current designs of man powered pumps for use in 3rd world locations are not any better than what I was doing 20 years ago. And opportunities and media (e.g. the Internet) for dissemination of information have bettered by leaps and bounds during those 20 years. So here is the report. Note that some of the lengthy stuff like a survey of alternative pumps and a survey of human power output is shortened or deleted to avoid boredom or duplication with many other publications. There is nothing extremely clever or exceptional about this pump, but it is a nice design which works well with or without modification.
