Michael Smith Engineers have introduced a range of plastic magnet-drive centrifugal pumps which are designed for use in the most corrosive and challenging environments. The Finnish Thompson DB Series of leak-free pumps comprises eight new models which are available in a choice of either polypropylene or PVDF, and provide flows up to 27m³/hr and heads up to 27 metres.
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 efficiently. 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.
