The DB22 model plastic magnet-drive centrifugal pump handles capacities up to 50m3/h at maximum differential heads up to 45m. These robust, leak-free pumps are suited for the challenging liquids transfer applications occurring in corrosive and challenging environments. The non-metallic materials used for both the housing and all the key wetted components makes them suitable for pumping corrosive liquids manufacturing and processing or wherever hazardous liquids need to be transferred. A close-coupled design configuration allows for optimum magnet alignment and extended dry-running capability when specified with a carbon bushing.
