Description
APP pumps are positive displacement axial piston pumps, flow is proportional to the number of revolutions(rpm), unlike centrifugal pumps, they produce a fixed flow at a given speed no matter what the discharge pressure.
APP1.8/APP2.2/APP2.5/APP3.5 high pressure desalination pumps are axial piston pumps designed for seawater desalination RO(reverse osmosis) system with flow rate 1.6/2.2/2.5/3.5 m³/h @ 3000rpm, max. pressure 80bar.
