US manufacturer Finish Thompson Inc’s DB22 model that it introduced last year in its range of plastic magnet-drive centrifugal pumps has been launched in the wider international market through Michael Smith Engineers, UK.

Offering capacities up to 50 cu m per hour at maximum differential heads up to 45 m, the DB22 can be used in corrosive or hazardous liquid transfer applications.
“As a result of the non-metallic materials used for both the housing and all the key wetted components, the DB22 is 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,” the company said in a statement.  “It is available in a close-coupled design configuration for optimum magnet alignment and provides extended dry-running capability when specified with a carbon bushing and is therefore protected from system upsets,” it added.
Other features and benefits specified by the company include: high operating efficiency resulting in lower energy consumption; improved hydraulic coverage for both 50 and 60 Hz operation with evenly spaced impeller trims enabling duty points to be precisely met; a two-piece impeller design which allows the impeller or inner drive magnet to be individually replaced.
