T he benefits of induced flow solar powered water pumps

This paper presents the case for using a novel type of solar water pump—the ‘induced flow’ pump. This type of pump is shown to be particularly appropriate for use with small, stand-alone units of up to 500 Wp, an area in which traditional solar powered water pumps do not excel. The pump is demonstrated to have performance characteristics combining those of centrifugal and reciprocating pumps over the full range of head and solar irradiance. Consequently the ‘induced flow’ water lifter offers considerable advantages over traditional, site-specific pumps and promises a significant advance in solar powered water pumping.  2003 Elsevier Science Ltd.
