Finish Thompson’s range of plastic magnet-drive centrifugal pumps has recently been expanded following the addition of a new DB22 model, which is capable of handling capacities up to 50m³/h at maximum differential heads up to 45m. These robust, leak-free pumps are ideal for most challenging liquids transfer applications occurring in corrosive and challenging environments. As a result of the non-metallic materials used for both the housing and all the key wetted components, they are ideal for pumping corrosive liquids in chemical manufacturing, metal plating, surface treatment, wastewater treatment, electronics manufacture or wherever hazardous liquids need to be transferred safely and effi ciently. They are available in a close-coupled design configuration for optimum magnet alignment and provide extended dry-running capability when specified with a carbon bushing and are therefore protected from system upsets.
