Modular pumps bring efficiencies

Positive displacement, water lubricated axial piston (AP) pump technology can be used in a modular arrangement to replace less efficient, centrifugal (CF) pumps that are currently the dominant solution for high pressure pumping used in large scale seawater reverse osmosis (SWRO) systems. A preliminary review of the modular positive displacement axial piston pump system reveals this new concept is not only a cost effective alternative to traditional centrifugal pump systems, but may have other advantages during the SWRO facility operating period.
