Designing a pedal-operated diaphragm pump and assessing its performance

Abstract

This research study presents the design and construction of a pedal-operated water pump that may be put to use in a variety of contexts, including garden irrigation, small-scale agriculture, and the removal of water from a reservoir. The pump that is controlled by pedalling may be constructed using just the resources and know-how available locally.  The water pumping apparatus consists of a centrifugal pump that may be powered by foot pedals.  The housing that the foot pedal and the rotating drive shaft will be linked to on the pump stand is included in the pump stand. It works according to the idea of compressing a tube and then suddenly releasing it. This creates a negative pressure within the tube, which in turn creates a vacuum that sucks water from the sump.  This pump, which is controlled by a bicycle's pedals, can extract water from wells and boreholes that are up to 23 feet deep at a rate of 25 to 30 litres per minute. Irrigation and drinking water are provided by it in areas where there is no access to power. It is possible to construct it using materials that are readily accessible in the area, and it is easy to modify it so that it meets the requirements of the people living there. The user saves money on ever-increasing energy expenses, it can be used anywhere, it does not cause pollution, and it provides a good kind of exercise.
