Abstract
A pump comprises two discrete series of pumping stages, the first having a lower liquid output than the second. The liquid is recirculated from a processing enclosure in particular using reverse osmosis, nanofiltration or the like, to the second series of processing stages where it is mixed with liquid from the first series of stages, whereafter the resulting mixture is conveyed to the processing enclosure. With this high-output system, no second pump is required.
