Abstract: This paper deals with the research and development work carried out on a traditional water lifting device known as the Rope Pump, with a view to increase its pumping rate and efficiency. The research work resulted in developing and modifying the traditional device to a considerable extent. The newly designed pump, named as the Endless Piston Water Pump (EPWP) delivers 100% more water at the expense of 50% less energy than the traditional pump. Moreover, the EPWP may be installed in boreholes as well as in open wells. The above improvement is possible because the EPWP remedies two shortcomings in the Rope Pump, -namely, the escape of water between rope knot and riser pipe and the slip of the rope on the main pulley.
