The Danfoss range of PAHT G high-pressure pumps is specifically designed for use with technical water such as: Ultra-pure water that has undergone multiple reverse osmosis processes, De-ionized water, Demineralized water Danfoss PAHT G pumps are positive displacement pumps, with axial pistons that move a fixed amount of water in each cycle. Flow is proportional to the number of input shaft revolutions (rpm). Unlike centrifugal pumps, they produce the same ow at a given speed independently of no matter what the discharge pressure. The range of PAHT G pumps is based on the standard PAHT pump series. The PAHT G pumps are made with extra coatings that reduce the wear of the pump. This coating is particularly important for pumps used in gas turbine applications or other similar applications where the wear of the pumps is higher due to the ultra pure water quality.
